BACKGROUND OF THE INVENTION
• 1. Field of Invention
• The present invention relates generally to the field of content and/or data delivery over a network. More particularly, the present invention is related in one exemplary aspect to apparatus and methods for the selection and insertion of secondary content.
• 2. Description of Related Technology
• In the context of network services, it is often highly desirable to provide users of the network with ready and instant access to a variety of different types of content, accessible at different locations, and on different platforms. In many cases, it is also desirable to provide the same user with “secondary” content (such as e.g., advertisements, promotions or “info-mercials”, related shorts, telescoping information/advertisements, etc.). The secondary content may be directly or indirectly related to the “primary” content which the user selected in the first place (such as via a common theme or context, common persons of interest, common demographic factors, etc.), or can be totally unrelated.
• Secondary content insertion may comprise a major source of revenue for commercial television distributors, and for the network operator. For example, where the secondary content comprises advertisements, it may be a main source of income for national television broadcasters and their local over-the-air affiliates. Cable, satellite, and other content distribution networks, as well as Internet content providers, also derive income from the sale of advertising time.
• Hence, an advertiser may seek to maximize the return on their advertising investment by targeting specific subscribers which are likely to be most receptive to the commercial message embodied in the advertisements. One of the most widespread and simplest ways of targeting viewers involves identifying what types of viewers generally watch specific television programs. For example, it may be found that sports programming is overwhelmingly viewed by men ages 18-32; if it is also true that this segment of the population includes a number of persons who are likely to purchase automobiles, an advertiser may take advantage of this information and provide automobile advertisements during e.g., football games, or advertisements logically coupling the two topics (e.g., an automobile advertisement involving a well recognized sports figure).
• Another method of targeting specific viewers involves selecting advertisements based on a geographical region in which the advertisement is to be broadcast. In other words, it is advantageous to provide certain advertising content to viewers in one local or regional area which is different than that provided to the viewers in a different local or regional area. For example, the advertisements may be limited by the geographic area in which the business operates. Hence, it would typically only make financial sense for an advertisement for that business to be provided in geographical areas where the business is operated.
• Currently, the aforementioned mechanisms are limited with respect to providing secondary content insertion into programming, such as that requested “on demand”. Examples of on-demand content include e.g., video on-demand or VOD, subscription video-on-demand (SVOD), which gives customers on-demand access to the content for a flat monthly fee, free video-on-demand (FVOD), which gives customers free on-demand access to some content, and movies on-demand (MOD), which provides on-demand access to movie content only.
• The aforementioned on-demand services may be provided to customers without secondary content inserted therein, or having secondary content which is not targeted or applicable to all viewers. In the first instance, prior art approaches fail to provide an effective mechanism for the insertion of secondary content into on-demand (or other content such as previously recorded content) that did not originally have secondary content inserted therein.
• With respect to the second instance, on-demand (or other content) having secondary content inserted therein under the prior art approaches may only be provided to customers “as is”. For example, under the previous methods, when content is recorded the secondary content therein cannot be easily modified to be targeted to a subsequent group of viewers or updated to insert more temporally relevant content.
• Just as different varieties of VOD service offerings have evolved over time, several different network architectures have also evolved for deploying these services. These architectures range from fully centralized (e.g., VOD servers at a central location) to fully distributed (e.g., multiple copies of content distributed on servers or other “edge” devices very close to customer premises), as well as various other network architectures enabling distribution of on-demand (and other) content to devices outside the traditional home network. Since most cable television networks today consist of optical fiber towards the “core” of the network which are connected to coaxial cable or copper wire networks towards the edge, VOD transmission network architectures also consist of a mixture of optical fiber and coaxial/wire portions. As these technologies emerge, there has been a noticeable lag in the ability of the network operator to ensure the content delivered to the remote devices also includes secondary content targeted to these subscribers, their locations, and/or to the capabilities of the requesting devices.
• Hence, apparatus and methods for providing primary content having secondary content inserted therein to a plurality of users are desired. Ideally, these apparatus and methods would be monitored and controlled by various management entities of the network, and may be used to provide content to users no matter where they are located (and regardless of their hardware/software context). Efficient delivery of the primary and secondary content is also desired. Secondary content insertion which targets the user, the device, and/or is related to the context of the primary content, would also ideally be provided.

Overview
• The present invention discloses, inter alia, methods and apparatus for providing primary content to network users, the primary content having secondary content (e.g., targeted advertisements or promotions, info-mercials, telescoping advertisements, etc.) inserted therein, or otherwise associated therewith.
• In one exemplary aspect, a network operator's on-demand product portfolio (e.g., single selection/purchase VOD, SVOD, FVOD, etc.) is leveraged as a platform for multiple different types of targeted secondary content insertion, offered as placement opportunities to prospective or existing advertisers. This approach also advantageously provides the opportunity for generating a new revenue stream for the network operator by creating placement opportunities where none existed before.
• In one variant, an “upfront” secondary content insertion model is provided, which takes advantage of non-advertising supported on-demand platforms (e.g., FVOD, NDVR, etc.) to provide placement opportunities to advertisers before the start of the primary content event. This approach is also extensible to general VOD paradigms, such as with a subscriber opt-in.
• In another variant, a “pause” secondary content insertion model is utilized which provides a dynamic placement opportunity for additional secondary content (e.g., advertising) when the subscriber returns to an on-demand content element (e.g., FVOD, Startover, Lookback, or NDVR content element) already being viewed, after having been paused for a time. Other variants for stopped content, and content played to completion, are also described.
• In another aspect of the invention, a “network promotion” product or model is disclosed which allows clients of an MSO (e.g., studios, networks, advertisers, etc.) to utilize the foregoing upfront and/or pause tools to specifically target advertising or other secondary content based on the characteristics of the subscriber and/or the particular on-demand asset being viewed.
• In one implementation of the foregoing, a content and data distribution network comprising primary content sources and secondary content sources, at least one content server, and management entities which cooperate to provide content (including secondary content) to various CPE and portable media devices (PMD) in communication with the network (including via a non-MSO network) is utilized. Various management entities are given which cooperate to provide VOD content having advertising or other secondary content inserted therein to the CPE and PMD. The inserted secondary content may include for example targeted advertisements, multimedia applications, interactive programming, scheduled programming (e.g., “live”) content, etc. The primary content may include for instance long form content (i.e., content into which secondary content has not yet been inserted) or short form content (i.e., content having secondary content inserted therein).
• In another embodiment, viewing patters of the CPE are monitored at the headend of the network and the selection of secondary content is based in part on the monitored viewing patterns. Secondary content insertion is further managed in one variant by a “campaign manager”, in accordance with various business rules.
• In another embodiment, the apparatus is configured so that all of the available primary and secondary content may be pushed to the edge of the network if desired, in order to facilitate more efficient transmission thereof to the client. In addition, the content may be pushed to edge devices (such as local service nodes) based on the applicability of the content to the group of devices serviced by the edge device (e.g., the service group associated with the node), thereby making content which is specific to a certain group of users available to the server or node which services these users.
• Several methods are discussed for the insertion of secondary content including e.g., a replacement model, a fill model and an additive model for content insertion. According to one implementation of the replacement model, one or more segments of secondary content are used to replace one or more segments of secondary content currently resident within a primary content element. For example, the segments may be replaced “one-for-one”, “one-for-N”, or “N-for-one”.
• The fill model is used to insert secondary content into primary content which does not otherwise have secondary content inserted therein, and/or may be used to increase the frequency of inserted secondary content therein.
• Lastly, the additive model is used to insert secondary content in a non-disruptive fashion into primary content which does not otherwise have secondary content inserted therein, and/or non-disruptively increase the frequency of inserted secondary content. In one example, the fill model may insert secondary content according to user-initiated interruptions, thereby appearing non-disruptive to the viewer.
• The foregoing secondary content insertion models may be utilized for example to replace secondary content targeted to a particular geographic area designated by a network operator (a so-called “advertisement zone”) with: (i) secondary content targeted to another (different) advertisement zone, (ii) national advertisements, and/or (iii) more specifically targeted advertisements (discussed below). These models may further be advantageously used to replace secondary content so that a given user will receive the same secondary content no matter the device, location, or network/device context from which the request originates. For example, a user request originating from a mobile device for content to be delivered from an IP network will receive the exact same secondary content which that user would receive if the request had originated from the user's CPE (e.g., STB) at home.
• In one variant, a client application is run on the microprocessor of the CPE to facilitate the secondary content insertion of the invention by providing information regarding the subscriber/user (and/or device) to headend entities charged with inserting secondary content (e.g., the management entities discussed above). For example, the client application may provide subscriber, account, or other information upstream in order for the insertion entities to identify the subscriber, and provide content based on what is known about that particular subscriber. In addition, the client application may be configured to collect information regarding the user's actions with respect to content. For example, the client application may log or record button presses, playback events, power up/down events, trick mode events, etc., and pass this information to the headend entities.
• In yet another embodiment, the aforementioned headend entities charged with inserting secondary content may provide the playlist of available secondary content, and/or the secondary content itself, directly to the CPE for storage thereon. The client application in this embodiment dynamically causes insertion of the provided secondary content. A proxy store (e.g., network store, web server, etc.) may also provide the secondary content directly to the CPE.
DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS
• Exemplary embodiments of the apparatus and methods of the present invention are now described in detail. While these exemplary embodiments are described in the context of the aforementioned hybrid fiber coax (HFC) cable system or satellite network architecture having an multiple systems operator (MSO), digital networking capability, IP delivery capability, and plurality of client devices/CPE, the general principles and advantages of the invention may be extended to other types of networks and architectures, whether broadband, narrowband, wired or wireless, or otherwise, the following therefore being merely exemplary in nature. For instance, the invention may be adapted for use on so-called hybrid fiber copper (HFCu) networks, or WiMAX (IEEE Std. 802.16) wireless networks.
• It will also be appreciated that while described generally in the context of a consumer (i.e., home) end user domain, the present invention may be readily adapted to other types of environments (e.g., commercial/enterprise, government/military, etc.) as well. Myriad other applications are possible.
• It is further noted that while described primarily in the context of a cable system with 6 MHz RF channels, the present invention is applicable to literally any network topology or paradigm, and any frequency/bandwidth, such as for example 8 MHz channels. Furthermore, as referenced above, the invention is in no way limited to traditional cable system frequencies (i.e., below 1 GHz), and in fact may be used with systems that operate above 1 GHz band in center frequency or bandwidth, to include without limitation so-called ultra-wideband systems.
• Also, while certain aspects are described primarily in the context of the well-known Internet Protocol (described in, inter alia, RFC 791 and 2460) and Session Initiation Protocol (SIP), it will be appreciated that the present invention may utilize other types of protocols (and in fact bearer networks to include other internets and intranets) to implement the described functionality.
• Moreover, while many aspects of the invention are described within the context of traditional “on demand” services provided over e.g., a cable, satellite, of HFCu network (e.g., FVOD, SVOD, MOD, etc.), it will be appreciated that the concepts and apparatus described herein are readily extensible to other content delivery paradigms which provide content “on demand”, including without limitation: (i) “pay per view”; (ii) content rental or purchase via mail or other tangible delivery platform (e.g., the prior art “Netflix®” service); and (iii) selection of a video for play via the Internet, such as via the “YouTube®” website. See the discussion regarding alternate on-demand delivery paradigms provided subsequently herein.
• Other features and advantages of the present invention will immediately be recognized by persons of ordinary skill in the art with reference to the attached drawings and detailed description of exemplary embodiments as given below.
Network—
• FIG. 1 illustrates a typical content delivery network configuration with which the apparatus and methods of the present invention may be used. The various components of thenetwork100 include (i) one or more data and application origination points102; (ii) one ormore content sources103, (iii) one or moreapplication distribution servers104; (iv) one ormore VOD servers105, and (v) customer premises equipment (CPE)106. The distribution server(s)104,VOD servers105 and CPE(s)106 are connected via a bearer (e.g., HFC)network101. A simple architecture comprising one of each of theaforementioned components102,104,105,106 is shown inFIG. 1 for simplicity, although it will be recognized that comparable architectures with multiple origination points, distribution servers, VOD servers, and/or CPE devices (as well as different network topologies) may be utilized consistent with the invention. For example, the headend architecture ofFIG. 1a(described in greater detail below) may be used.
• The data/application origination point102 comprises any medium that allows data and/or applications (such as a VOD-based or “Watch TV” application) to be transferred to adistribution server104. This can include for example a third party data source, application vendor website, CD-ROM, external network interface, mass storage device (e.g., RAID system), etc. Such transference may be automatic, initiated upon the occurrence of one or more specified events (such as the receipt of a request packet or ACK), performed manually, or accomplished in any number of other modes readily recognized by those of ordinary skill.
• Theapplication distribution server104 comprises a computer system where such applications can enter the network system. Distribution servers are well known in the networking arts, and accordingly not described further herein.
• TheVOD server105 comprises a computer system where on-demand content can be received from one or more of theaforementioned data sources102 and enter the network system. These servers may generate the content locally, or alternatively act as a gateway or intermediary from a distant source.
• TheCPE106 includes any equipment in the “customers' premises” (or other locations, whether local or remote to the distribution server104) that can be accessed by adistribution server104.
• Referring now toFIG. 1a, one exemplary embodiment of a headend architecture useful with the present invention is described. As shown inFIG. 1a, theheadend architecture150 comprises typical headend components and services includingbilling module152, subscriber management system (SMS) and CPEconfiguration management module154, cable-modem termination system (CMTS) andOOB system156, as well as LAN(s)158,160 placing the various components in data communication with one another. It will be appreciated that while a bar or bus LAN topology is illustrated, any number of other arrangements as previously referenced (e.g., ring, star, etc.) may be used consistent with the invention. It will also be appreciated that the headend configuration depicted inFIG. 1ais high-level, conceptual architecture and that each MSO may have multiple headends deployed using custom architectures.
• Theexemplary architecture150 ofFIG. 1afurther includes a multiplexer-encrypter-modulator (MEM)162 coupled to theHFC network101 adapted to process or condition content for transmission over the network. Thedistribution servers164 are coupled to theLAN160, which provides access to theMEM162 andnetwork101 via one ormore file servers170. TheVOD servers105 are coupled to theLAN160 as well, although other architectures may be employed (such as for example where the VOD servers are associated with a core switching device such as an 802.3z Gigabit Ethernet device). As previously described, information is carried across multiple channels. Thus, the headend must be adapted to acquire the information for the carried channels from various sources. Typically, the channels being delivered from, theheadend150 to the CPE106 (“downstream”) are multiplexed together in the headend, as previously described and sent to neighborhood hubs (FIG. 1b) via a variety of interposed network components.
• It will also be recognized, however, that the multiplexing operation(s) need not necessarily occur at the headend150 (e.g., in the aforementioned MEM162). For example, in one variant, at least a portion of the multiplexing is conducted at a BSA switching node or hub (see discussion ofFIG. 1cprovided subsequently herein). As yet another alternative, a multi-location or multi-stage approach can be used, such as that described in U.S. Pat. No. 7,602,820, entitled “APPARATUS AND METHODS FOR MULTI-STAGE MULTIPLEXING IN A NETWORK” incorporated herein by reference in its entirety, which discloses inter alia improved multiplexing apparatus and methods that allow such systems to dynamically compensate for content (e.g., advertisements, promotions, or other programs) that is inserted at a downstream network node such as a local hub, as well as “feed-back” and “feed forward” mechanisms for transferring information between multiplexing stages.
• Content (e.g., audio, video, data, files, etc.) is provided in each downstream (in-band) channel associated with the relevant service group. To communicate with the headend or intermediary node (e.g., hub server), theCPE106 may use the out-of-band (OOB) or DOCSIS channels and associated protocols. The OCAP 1.0, 2.0, 3.0 (and subsequent) specification provides for exemplary networking protocols both downstream and upstream, although the invention is in no way limited to these approaches.
• It will also be recognized that the multiple servers (broadcast, VOD, or otherwise) can be used, and disposed at two or more different locations if desired, such as being part of different server “farms”. These multiple servers can be used to feed one service group, or alternatively different service groups. In a simple architecture, a single server is used to feed one or more service groups. In another variant, multiple servers located at the same location are used to feed one or more service groups. In yet another variant, multiple servers disposed at different location are used to feed one or more service groups.
“Switched” Networks—
• FIG. 1cillustrates an exemplary “switched” network architecture also useful with the present invention. While a so-called “broadcast switched architecture” or BSA network is illustrated in this exemplary embodiment, it will be recognized that the present invention is in no way limited to such architectures.
• Switching architectures allow improved efficiency of bandwidth use for ordinary digital broadcast programs. Ideally, the subscriber is unaware of any difference between programs delivered using a switched network and ordinary streaming broadcast delivery.
• FIG. 1cshows the implementation details of one exemplary embodiment of this broadcast switched network architecture. Specifically, theheadend150 contains switched broadcast control and media path functions190,192; these element cooperating to control and feed, respectively, downstream oredge switching devices194 at the hub site which are used to selectively switch broadcast streams to various service groups. ABSA server196 is also disposed at the hub site, and implements functions related to switching and bandwidth conservation (in conjunction with amanagement entity198 disposed at the headend). Anoptical transport ring197 is utilized to distribute the dense wave-division multiplexed (DWDM) optical signals to each hub in an efficient fashion.
• Co-owned and co-pending U.S. patent application Ser. No. 09/956,688 filed Sep. 20, 2001 and entitled “TECHNIQUE FOR EFFECTIVELY PROVIDING PROGRAM MATERIAL IN A CABLE TELEVISION SYSTEM”, incorporated herein by reference in its entirety, describes one exemplary broadcast switched digital architecture useful with the present invention, although it will be recognized by those of ordinary skill that other approaches and architectures may be substituted.
• In addition to “broadcast” content (e.g., video programming), the systems ofFIGS. 1aand1c(and1ddiscussed below) also deliver Internet data services using the Internet protocol (IP), although other protocols and transport mechanisms of the type well known in the digital communication art may be substituted. One exemplary delivery paradigm comprises delivering MPEG-based video content, with the video transported to user PCs (or IP-based STBs) over the aforementioned DOCSIS channels comprising MPEG (or other video codec such as H.264 or AVC) over IP over MPEG. That is, the higher layer MPEG- or other encoded content is encapsulated using an IP protocol, which then utilizes an MPEG packetization of the type well known in the art for delivery over the RF channels. In this fashion, a parallel delivery mode to the normal broadcast delivery exists; i.e., delivery of video content both over traditional downstream QAMs to the tuner of the user's STB or other receiver device for viewing on the television, and also as packetized IP data over the DOCSIS QAMs to the user's PC or other IP-enabled device via the user's cable modem. Delivery in such packetized modes may be unicast, multicast, or broadcast.
• Referring again toFIG. 1c, the IP packets associated with Internet services are received byedge switch194, and in one embodiment forwarded to the cable modem termination system (CMTS)199. The CMTS examines the packets, and forwards packets intended for the local network to theedge switch194. Other packets are discarded or routed to another component.
• Theedge switch194 forwards the packets receive from theCMTS199 to theQAM modulator189, which transmits the packets on one or more physical (QAM-modulated RF) channels to the CPE. The IP packets are typically transmitted on RF channels (e.g., DOCSIS QAMs) that are different that the RF channels used for the broadcast video and audio programming, although this is not a requirement. TheCPE106 are each configured to monitor the particular assigned RF channel (such as via a port or socket ID/address, or other such mechanism) for IP packets intended for the subscriber premises/address that they serve.
“Packetized” Networks—
• While the foregoing network architectures described herein can (and in fact do) carry packetized content (e.g., IP over MPEG for high-speed data or Internet TV, MPEG2 packet content over QAM for MPTS, etc.), they are often not optimized for such delivery. Hence, in accordance with another embodiment of the present invention, a “packet optimized” delivery network is used for carriage of the packet content (e.g., IPTV content).FIG. 1dillustrates one exemplary implementation of such a network, in the context of a 3GPP IMS (IP Multimedia Subsystem) network with common control plane and service delivery platform (SDP), as described in co-pending U.S. Provisional Patent Application Ser. No. 61/256,903 entitled “METHODS AND APPARATUS FOR PACKETIZED CONTENT DELIVERY OVER A CONTENT DELIVERY NETWORK”, previously incorporated herein. Such a network provides significant enhancements in terms of common control of different services, implementation and management of content delivery sessions according to unicast or multicast models, etc.; however, it is appreciated that the various features of the present invention are in no way limited to any of the foregoing architectures.
Dynamic Insertion Network—
• FIG. 2 is a high-level block diagram of a content anddata distribution network200 configured in accordance with one embodiment of the invention and for use in dynamic secondary content insertion or dynamic advertisement insertion (DAI) as discussed herein. As illustrated, thenetwork200 generally comprises a plurality ofCPE106 adapted to receive content and data via acontent delivery network101, which in turn receives content and data from a content anddata distribution network200. In one embodiment, the content anddata distribution network200 comprises a plurality of entities located at anetwork headend150. As shown, thedistribution network200 comprisesprimary content sources202 andsecondary content sources208, at least one content server206 (e.g., aVoD server105 such as that shown inFIG. 1), and management entities which cooperate to provide content (including secondary content) tovarious CPE106 and portable media devices (PMD)107 in communication with the network101 (including via a non-MSO network103). The management entities include e.g., an advertisement management system, advertisement delivery manager, or advertisement decision manager (collectively and individually referred to as “ADM”)220, an advertisement decision service (ADS)222, and a campaign manager (CM)224.
• In one embodiment, communication between the content anddata distribution network200 andCPE106 and/orPMD107 occurs as discussed in previously incorporated co-owned U.S. Provisional Application Ser. No. 61/256,903 filed on Oct. 30, 2009 and entitled “Methods and Apparatus for Packetized Content Delivery Over a Content Delivery Network”. As discussed therein, a substantially session-based and packetized content delivery approach (e.g., using the well-known Internet Protocol) which allows for temporal, device, and location flexibility in the delivery of the content, and transportability/migration of user sessions (i.e., allows a user to receive any content they desire, delivered at any time and at any location, and on any device they choose), as well as service/content personalization (e.g., on a per-session/user basis) and blending (integration). This approach uses a common or unified delivery architecture in providing what were heretofore heterogeneous services supplied by substantially different, and often vendor-specific, networks.
• Moreover, the foregoing apparatus and methods provide for enhanced content access, reproduction, and distribution control (via e.g., a DRM-based approach and other security and content control measures), as well as quality-of-service (QoS) guarantees which maintain high media quality and user experience, especially when compared to prior art “Internet TV” paradigms. In one exemplary implementation, the network may be based on an IMS (IP Multimedia System, such as e.g., that defined in relevant 3GPP standards) which includes SIP session protocols, as well as a Service Delivery Platform (SDP). In another implementation, the network comprises both “managed” and “unmanaged” (or off-network) services, so that a network operator can utilize both its own and external infrastructure to provide content delivery to its subscribers in various locations and use cases.
• In one variant of this approach, network services are sent “over the top” of other provider's infrastructure, thereby making the service network substantially network-agnostic. In another variant, a cooperative approach between providers is utilized, so that features or capabilities present in one provider's network (e.g., authentication of mobile devices) can be leveraged by another provider operating in cooperation therewith.
• In another embodiment, content may be provided from the content anddata distribution network200 to theCPE106 and/orPMD107 as described in co-owned, co-pending U.S. patent application Ser. No. 11/258,229 filed on Oct. 24, 2005 and entitled “METHOD AND APPARATUS FOR ON-DEMAND CONTENT TRANSMISSION AND CONTROL OVER NETWORKS”, which is incorporated herein by reference in its entirety. As discussed therein, data may be provided according to download or “on demand” paradigms. In one embodiment, the network comprises a cable television network connected with a CSP (cellular service provider) or wireless service provider (WSP), and on-demand content delivery is accomplished via a “point-to-point” approach wherein a session is established between a content receiving entity (such as a cellular telephone) and a distributing entity (e.g., a VOD server). Session establishment and data flow control are advantageously implemented using protocols and bandwidth that are typically used for (i) providing on-demand services to subscribers within the cable network, and (ii) delivery and control of streaming multimedia to client mobile devices.
• In yet another embodiment, content may be purchased and/or received at a device in a remote network as discussed in co-owned, co-pending U.S. patent application Ser. No. 11/440,490 filed on May 24, 2006 and entitled “PERSONAL CONTENT SERVER APPARATUS AND METHODS”, which is incorporated herein by reference in its entirety. As discussed therein, access to content (e.g., program viewing) delivered over a content-based network via other networks or communication channels outside of the content-based network are provided. For example, in the context of a cable television network, programming or other content delivered to a subscriber over the cable network can be accessed via other (secondary) networks such as the Internet, LANs/WANs/MANs, a wireless service provider (WSP) network, cellular service provider (CSP) network, or even a satellite network. In one embodiment, a personal content server located, e.g., at the head-end of the bearer (cable) network may be used to distribute content to the remote requesting location(s), thereby eliminating repetitious traffic to and from subscriber's premises to fulfill the requests for remote content delivery. Information relating to the requesting subscriber's prior activity for the requested content may be used as a basis for authorizing delivery of the remote content. A “network DVR” or “virtual DVR” may be used to provide remote access privileges to content to a subscriber at a location outside the bearer network and/or who does not have a DVR on his premises. In one variant, the network DVR may be web-based, thereby allowing subscribers to request and access content from a website. Broadcast or “live” content can also be accessed via the secondary network approach discussed.
• Yet other mechanisms and architectures for providing content to PMDs or CPE located in or out of a managed network may be used consistent with the invention as well, the foregoing being merely exemplary of the broader principles.
• Referring now toFIG. 2a, a detailed block diagram illustrating one embodiment of the content anddata distribution network200 ofFIG. 2 is shown. As illustrated, thenetwork200 generally comprises primary content (e.g., VOD content)sources202 and secondary content (e.g., advertisement content)sources208, at least oneVOD content server206 anapplication server214, and various management entities including e.g., an advertisement management system (ADM)220, an advertisement decision service (ADS)222, a campaign manager (CM)224, a package media gateway (PMG)210, and a business management system (BMS)212. ThePMG210 in the illustrated embodiment performs content packaging and movement throughout the network. ThePMG210 also acts as a storage and forwarding device, allowing the content to be “manipulated”. TheBMS212 is a VOD back office component including metadata management and package/entitlement management functions. The aforementioned components, similar to those discussed above with respect toFIG. 2, cooperate to provide VOD content having advertisement content inserted therein to theCPE106 andPMD107 in communication via the network101 (and/or via a non-MSO network (not shown) in communication with the network101).
• Although discussed herein with respect to advertisement insertion into VOD content, it is appreciated that the foregoing may be utilized in conjunction with the provision of various types of primary and secondary content. For example, multimedia applications, interactive programming, linear or scheduled programming (e.g., “live”) content, etc. may be provided.
• Additional headend entities are provided in the detailed embodiment ofFIG. 2awhose function will be discussed subsequently herein. These entities also work in conjunction with the aforementioned content sources (202,208), management entities (220,222,224,210,212), and content server (206,214), in order to provide authorization and content to theCPE106 and/orPMD107.
• It is further appreciated that one or more of the aforementioned components may be disposed at various other locations as desired consistent with the architecture implemented (e.g., closer to the network edge, such as at the BSA hub in a BSA network).
• In the illustrated embodiment, long form content is received at one or morecontent catchers204 from a plurality ofcontent sources202. The long form content comprises content which into which secondary content has not yet been inserted. In one embodiment, long form content is not formatted for secondary content insertion. The long form content is presented to the users, in one embodiment, as on-demand content. Content retrieved via thecatchers204 is transmitted to a video on-demand (VOD)server206 for storage. In this model, the VOD platform effectively acts as a splicer from the “streamer” at session playout. Alternatively, short form content may be received at one or morecontent catchers204 from a plurality ofcontent sources202, as discussed elsewhere herein.
• Metadata regarding the assets stored at theVOD server206 is maintained, and utilized to catalogue and carousel the offerings by the broadcast file system (BFS)216. TheBFS216 performs the basic function of a data carousel. In the illustrated embodiment, a switched digital video manager (SDV/M)234 is consulted to see if there is available bandwidth to support the playout of additional stream in a shared bandwidth model. In another embodiment, a global resource session manager or GSM (not shown) may be used to manage the resources in the network.
• One or moreadvertisement content sources208 are also illustrated. Advertisement content is received from theadvertisement content sources208 and via thePMG210. The secondary content is transmitted to the enhanced TV application gateway (ETAG)238 andHTA240. TheETAG238 is responsible for the “spooling”/streaming of interactive content (EBIF) and receiving any responses from the clients. The secondary content is also delivered from thePMG210 to theVOD server206. In this manner, the advertisement content may be inserted into other VOD content prior to delivery to the users.
• FIG. 2 further illustrates that the advertisement content is provided as short form content to theVOD server206. The campaign manager (CM)224, advertisement decision service (ADS)222, and advertisement management system (ADM)220 cooperate to manage insertion of the secondary content (e.g., advertisements) into the primary content (e.g., VOD content).
• Communication between theCM224 andADS222 occurs via the traffic and billing interface (T&B)236. TheT&B system236 traffics linear advertising insertion, and is responsible for producing affidavits for billing purposes. The interface between theCM224 and may comprise e.g., any number of CCMS (Content and Campaign Management System) schedule files, or other appropriate interface/file transfer mechanisms. TheADM220 communicates with theCM224 via an entity providing a centralized view of all the advanced advertising systems in network (MSSV234) and business intelligence (BI)226 entities.
• In one embodiment, theADM220 andADS222 are of the type discussed in co-owned, co-pending U.S. patent application Ser. No. 12/503,749 filed on Jul. 15, 2009 and entitled “METHODS AND APPARATUS FOR EVALUATING AN AUDIENCE IN A CONTENT-BASED NETWORK”, which is incorporated herein by reference in its entirety.
• In another embodiment, theADM220 andADS222 are adapted to comply with the requirements set forth in the Society of Cable Telecommunications Engineers SCTE 130-1, 130-2, and SCTE 130-3 Digital Program Insertion—Advertising Systems Interfaces standards, each of which is incorporated herein by reference in its entirety.
• TheADM220 is utilized to select individual ones of a plurality of secondary content for delivery to individual ones of theCPE106 via an application server (AS)214. TheADM220 is in communication with theADS222; theADS222 determines individual ones of the plurality of secondary content from the content store to deliver to theCPE106 based in part on data collected from a headend collecting entity.
• TheAS214 is the headend entity responsible for monitoring viewing patterns of thevarious CPE106, and providing content thereto based on the information collected by the monitored viewing patterns. TheAS214 may further enable dynamic insertion of secondary content prior to distribution, in accordance with one embodiment of the invention.
• In one embodiment, theapplication server214 comprises an application server (AS) such as that discussed in co-owned, co-pending U.S. patent application Ser. No. 11/263,015 filed Oct. 2, 2002 and entitled “NETWORK BASED DIGITAL INFORMATION AND ENTERTAINMENT STORAGE AND DELIVERY SYSTEM”, now published as U.S. Patent Application Publication No. 2003/0208767, each of the foregoing incorporated herein by reference in its entirety. In one variant, theAS214 is a Mystro™ server device of the type utilized by the Assignee hereof, although it will be appreciated that other configurations may be utilized with equal success. With respect to the aforementioned exemplary embodiment utilizing the Mystro server, it is appreciated that the present invention may take advantage of the start-over acquisition process to capture broadcast linear television after local advertisement insertion has occurred. Alternatively, in another embodiment, the network feed may be captured, and have the local advertisements inserted back into the stream from the VOD system. As discussed therein, theAS214 monitors the content reserved and viewed by a user, and thus can create a profile relating to the user's interests. This information may then be used to assist (theADM220 and ADS222) in providing targeted advertising that would be of most use and interest to the user (and therefore most effectiveness to advertisers). Further, because reserved programs are recorded prior to distribution to a user, theAS214 may provide the ability to vary advertising content prior to distributing a program to the CPE106 (e.g., dynamically, in response to changing events or conditions).
• The aforementioned concepts may be applied in the context of VOD programming presentation as well. In other words, since VOD programming is pre-stored at the VOD server, theAS214 may perform one or more of the steps necessary for VOD session setup. Further, the ADM portion of the MAS backoffice may be responsible obtaining an advertisement decision and working with the VOD system to create a stream. The VOD system is responsible for the actual content splicing, multiplexing and transmitting to the user.
• The dynamic insertion of secondary content is further monitored and controlled by the business management system (BMS)212 ofFIG. 2.
• TheADM220 andADS222 may be further utilized for reporting purposes. For example, theADM220 andADS222 may cooperate to transmit secondary content to CPE106 (discussed above) and simultaneously send metadata regarding the secondary content to a collectingentity230 and report generatingentity228. In one embodiment, the collectingentity230 and report generating entities comprise e.g., Everstream™ products, such as the interactive data gateway (EV-IDG) product, and/or the interactive data warehouse (EV-IDW) product.
• In another embodiment, a content information service (CIS), subscriber information service (SIS) and/or placement opportunity information service (POIS) communicate with theADM220 and/orADS222 to provide metadata and other information thereto. The CIS is an interface which describes a logical service, it may be run on any entity managing metadata or on an entity in communication with a second entity containing metadata describing the content. The CIS sources metadata to consumers (via the ADM and ADS). The CIS does not define how to move the content around, however a separate CIS implementation may be given to provide such functionality.
• Acampaign manager224 is utilized in the illustrated embodiment to manage the insertion of secondary content as discussed herein. In one embodiment, the campaign manager is of the type disclosed in co-owned, co-pending U.S. patent application Ser. No. 12/503,772 filed on Jul. 15, 2009 and entitled “METHODS AND APPARATUS FOR CLASSIFYING AN AUDIENCE IN A CONTENT-BASED NETWORK” which is incorporated herein by reference in its entirety, although other approaches may be used with equal success. As discussed therein, the campaign manger may comprise multiple components or processes which are either co-located or distributed across two or more entities (CM224) within the content anddata distribution network200. The campaign manager (CM224) enables an operator associated with MSO (or another entity) to control one or more aspects of secondary content selection and insertion, therefore enabling an operator to ensure that the goals of the secondary content providers (e.g., advertisers) are accomplished. TheCM224 further allows the MSO to create and maintain billing schema for the various secondary content providers. TheCM224 may further be adapted to manage conflicts, and optimize business value or other business-related parameters such as profit and/or revenue.
• Further, theCM224 provides a user interface which enables the operator associated with the MSO to perform the campaign management functions described herein, whether in whole or part, as well as make adjustments to settings, or simply monitor activity.
• In one model, in order for content to be provided to a CPE106 (or PMD), it must be determined that theCPE106 orPMD107 is “entitled” to the content. In one approach, this is accomplished via the methods and apparatus disclosed in co-owned, co-pending U.S. patent application Ser. No. 12/536,724 filed on Aug. 6, 2009 and entitled “SYSTEM AND METHOD FOR MANAGING ENTITLEMENTS TO DATA OVER A NETWORK”, which has been previously incorporated herein by reference in its entirety.
• As illustrated, the present system supports advertisement sales operations performed at both the regional and national levels. The centralized view of theentire footprint11 is provided to monitor system activity and performance. CCMS schedule files or other transfer files9A are obtained for planned or scheduled linear insertion. The campaign management to campaign management interface5D allows CM's from different entities to “exchange” campaigns and/or “placement opportunity” and inventory information.
• The various entities of the content anddata distribution network200 are responsible for providing data and/or content to theCPE106. These entities may comprise functionality located at one or more of the headend entities discussed above with respect toFIGS. 1-1d, or may comprise additional entities discussed herein. In one embodiment, thenetwork200 utilizes information obtained from or stored at an authorization server (not shown) to determine whether aCPE106 requesting content is authorized to receive the content. In another embodiment, restrictions to the provision of content to a user at a display device associated with theCPE106 are determined by theCPE106 itself, as discussed in co-owned, co-pending U.S. patent application Ser. No. 12/716,131 filed on Mar. 2, 2010 and entitled “APPARATUS AND METHODS FOR RIGHTS-MANAGED CONTENT AND DATA DELIVERY”, which is incorporated herein by reference in its entirety. As discussed therein, a downloadable or transferrable rights profile coupled with a “smart” media player application are given. The rights profile contains information regarding the specific rights of a device and/or a subscriber to access content. It is via the rights profile that the device (via the media player, and its associated rights management application) determines whether to provide content to a subscriber.
• Still further, thecontent server206 and/or theAS214 of theCPS204 may in one embodiment be adapted to utilize information regarding the CPE106 (or PMD107) capabilities (e.g., such as in the event a capabilities profile is received from these devices) to perform de-encapsulation/re-encapsulation of content where necessary as is disclosed in co-owned, co-pending U.S. patent application Ser. No. 12/582,619 filed on Oct. 20, 2009 and entitled “GATEWAY APPARATUS AND METHODS FOR DIGITAL CONTENT DELIVERY IN A NETWORK”, which is incorporated herein by reference in its entirety. As discussed therein, thecontent server206 of the present invention may be configured to process content including de-encapsulating the content from a first media file container format and subsequently re-encapsulating the content to a second media file container format which is known to be compatible with the requestingCPE106. For example, content which is delivered from a host server or other content source may be encapsulated in e.g., MP4, if the receivingCPE106 is not capable of reading the MP4 files, thecontent server206 may re-encapsulate the content to e.g., MPEG-2 or to another format that the receivingCPE106 is capable of reading. Other exemplary network architectures may be useful with the present invention as well. For example, thecontent server206 may provide data and/or content to a plurality of user devices via thenetwork101, including e.g., a converged premises device (CPD) and/or a media bridge. The CPD may for example be of the type described in co-owned and co-pending U.S. patent application Ser. No. 11/378,129 filed Mar. 16, 2006 and entitled “METHODS AND APPARATUS FOR CENTRALIZED CONTENT AND DATA DELIVERY”, incorporated herein by reference in its entirety. As discussed therein, the CPD comprises a WLAN (e.g., Wi-Fi) and/or PAN (e.g., Bluetooth or 802.15) wireless interface. Packetized (e.g., IP) traffic may be exchanged between the CPD and aPMD107 via, e.g. the WLAN/PAN interface. Hence, in one embodiment, thePMD107 may request content from the CPD.
• The media bridge apparatus may be for example of the type disclosed in co-owned, co-pending U.S. patent application Ser. No. 12/480,597 filed Jun. 8, 2009 and entitled “MEDIA BRIDGE APPARATUS AND METHODS”, incorporated herein by reference in its entirety. As discussed therein, the media bridging apparatus acts as a connection between a PMD107 (which may include e.g., an iPod™, handheld computer, smartphone, PDA, etc.) and a user's home network. This bridging apparatus may be used, for example, to convert content stored on the PMD205 to a format capable of being presented on a user's set-top box or other client device. The bridging apparatus may also be utilized for transmitting content to the PMD107 (such as by converting the content to a format capable of being stored/presented on the PMD107) provided the user of thePMD107 is authorized to receive the content.
• In another embodiment, all (or portions of) of the available primary and secondary content may be pushed to the edge of the network in order to facilitate more efficient transmission thereof to the client. In addition, the content may be pushed to edge devices, such as local service nodes, based on the applicability of the content to the group of devices serviced by the edge device (e.g., the service group associated with the node). For example, it may be determined that the CPE serviced by a particular local node are all within a given advertisement zone. Hence, secondary content specific to that advertisement zone may be pushed to the node which services that zone for more efficient delivery thereof.
Methodology—
• Referring now toFIG. 3, an exemplary method for providing primary and secondary content to a plurality of user devices (e.g.,CPE106 and/or PMD107) according to the present invention is described. As shown, perstep302, primary content is ingested. In the illustrated embodiment, the primary content comprises on-demand content of the type previously referenced herein.
• Alternatively, other types or forms of content may be ingested, and hence the method ofFIG. 3 can be readily applied and adapted to non-OD content delivery models. For example, so called “quick clips” content (described in co-owned U.S. Pat. No. 7,174,126 issued Feb. 6, 2007 and entitled “TECHNIQUE FOR EFFECTIVELY ACCESSING PROGRAMMING LISTING INFORMATION IN AN ENTERTAINMENT DELIVERY SYSTEM” incorporated herein by reference in its entirety), so-called “start-over” content (described in co-owned, co-pending U.S. Patent Publication No. 2005/0034171 entitled “TECHNIQUE FOR DELIVERING PROGRAMMING CONTENT BASED ON A MODIFIED NETWORK PERSONAL VIDEO RECORDER SERVICE” incorporated herein by reference in its entirety), so-called “lookback” content (as described in co-owned, co-pending U.S. patent application Ser. No. 10/913,064 filed Aug. 6, 2004 and entitled “TECHNIQUE FOR DELIVERING PROGRAMMING CONTENT BASED ON A MODIFIED NETWORK PERSONAL VIDEO RECORDER SERVICE” incorporated herein by reference in its entirety), and/or so-called “remote DVR” content (as discussed in co-owned U.S. Pat. No. 7,457,520 issued Nov. 25, 2008 and entitled “TECHNIQUE FOR PROVIDING A VIRTUAL DIGITAL VIDEO RECORDER SERVICE THROUGH A COMMUNICATIONS NETWORK” incorporated herein by reference in its entirety) may be ingested. Other types of content may be utilized consistent with the invention as well.
• In another embodiment, the types or forms of content ingested atstep302 may comprise long form and/or short form on-demand content.
• Next, perstep304, secondary content is ingested. In one embodiment, secondary content is obtained from one or more secondary content sources via aPMG210. ThePMG210 communicates the secondary content to the content server206 (which is monitored by the BMS212).
• Atstep306, a catalog of primary content offerings is created from metadata generated regarding the primary content received (at step302). In one embodiment, the catalog comprises a user readable listing of content which is presented to the user via a user interface displayed on the CPE106 (and/or PMD107). The catalog may bear substantial similarity to an electronic programming guide (EPG). In other words, the catalog presented to the user may comprise a series of selectable titles (or other program identifying information). A user may view the titles by using e.g., one or more menu functions/buttons on theCPE106,PMD107, or a remote control device. A user may select a particular one of the presented programs; the user's selection is then received at theDNCS218, and communicated to the BMS212 (step308).
• In response to the user selection, a stream is set up (step310). In the case where the content comprises on-demand content (or other content requiring a unicast delivery), the stream set up may comprise a resource negotiation.
• As will be discussed in greater detail herein below, one or more methods are implemented to provide for the insertion of secondary content into the requested primary content. Hence, theADM220 is contacted to set up a stream as well (step310). TheADM220 andADS222 cooperate to select one or more pieces of secondary content for insertion into the selected primary content (step312). Selection of targeted secondary content, as well as methods for the insertion of secondary content, are described subsequently herein.
• Perstep314, campaigns are entered and managed centrally. In other words, the campaign manager (CM)224 is consulted to ensure that the secondary content is inserted according to one or more management rules. TheCM224 as discussed above is configured to manage advertising campaigns for one or more advertisement/promotional providers in order to, for example, (i) increase advertising or associated sales revenue for an MSO, as well as to (ii) increase the likelihood a particular advertiser will reach its targeted audience as precisely as possible (and within any limitations of an advertiser-MSO defined relationship). As discussed below, these CM “rules” may also be overlaid with other logical rule sets or constructs (e.g., MSO operational and/or business goals, which may not always be compatible with the CM goals of precision targeting under (ii) above).
• Finally, perstep316, the selected primary content is provided to the user having the secondary content inserted therein.
• Referring now toFIG. 3a, a detailed implementation of the method ofFIG. 3 is given. As shown, perstep322, long form content is ingested into theVOD server206. As noted previously, long form content comprises content which does not have secondary content inserted therein and/or which is not formatted to have such secondary content inserted. In one embodiment, the long form content comprises content which does not have secondary content splice indicators.
• Next, perstep324, advertisements are received from one or more secondary content sources via e.g., thePMG210.
• Atstep326, the primary content offerings are cataloged and carouseled by theBFS216. The catalog of content is then presented to the client, which selects at least one offering to play (step330). In response to the selection, VOD resources are negotiated, and a stream is set up for delivery of the selected asset (step332).
• Atstep334, TheVOD server206 calls theADM220 to set up a stream for delivery of the selected asset. In order to fulfill the session setup, theADM220 requests an advertisement decision from the ADS (step336). TheADS222 determines individual ones of the plurality of secondary content from the content store to deliver to the requesting client.
• In one variant, the secondary content is selected based in part on data collected from a headend collecting entity regarding the requesting client or subscriber, the requesting device, or other factor. As will be discussed below, advertisement decisions may be based on an advertisement zone (as determined by e.g., zip code, area code, or other indicator assigned to a subscriber and/or device), unique characteristics of the requesting subscriber (demographics, psychographics, firmographics, and/or behavioral variables), or other factor.
• Next, atstep338, campaigns are entered and centrally managed. It is theCM224 which enters and manages the advertisement campaigns in the illustrated embodiment. TheCM224 permits the control of advertisement selection by an operator associated with the MSO. It is via theCM224 campaign management that the goals of the advertisers and/or the MSO are accomplished.
• Lastly, perstep340, the VOD asset having one or more secondary content elements (e.g., targeted advertisements) disposed therein is streamed to the client.
Secondary Content Insertion—
• As discussed previously, when a user selects content for delivery, theCM224,ADM220, andADS222 cooperate to select and insert secondary content into the requested primary content. Several methods are discussed herein for the insertion of secondary content, although the invention should in no way be considered limited to these described methods.
• When a CPE or PMD (e.g., set top box) establishes a session, a request is sent to the components at the headend that support dynamic secondary content insertion (e.g.,CM224,ADM220 and ADS222). In response to the request, a presentation stream is assembled by combining primary content and secondary content assets (also referred to elsewhere herein as “entertainment content assets (EC)” and “advertisement content assets (AC)”, respectively). The presentation stream is then delivered back to the set top box, where it plays out as an uninterrupted session.
• In one embodiment, secondary content may be inserted into any type of on-demand or on-demand-like programming. For example, secondary content may be inserted according to the present invention into video on-demand (VOD), free on-demand (FOD), subscription video on-demand (SVOD), movies on-demand (MOD), start-over, lookback etc. Although discussed herein with respect to secondary content insertion into session-based (on-demand) content, it is appreciated that the apparatus and methods discussed herein may also be utilized for dynamic secondary content insertion into linear (e.g., broadcast) or other non-session-based content with proper adaptation, such adaptation being readily within the skill of the ordinary artisan given the present disclosure.
• The models of secondary content insertion discussed herein provide for insertion: (i) prior to the start of the primary content, (ii) when primary content is paused, (iii) when primary content is stopped prior to completion, and/or (iv) when primary content plays to completion. It will be appreciated, however, that the invention is not limited to these four instances or scenarios. For example, it may be that a “rewind” or “FF” model is used, so that an advertisement or placement opportunity is created when these functions are invoked. Moreover, if the same primary content is replayed (e.g., a movie watched twice within a prescribed availability window), the secondary content inserted at the second play might be made to be different or the same same as that for the first play, depending on the advertiser/MSO (or even user) preference.
• In one embodiment, high definition (HD) content segments are down-converted prior to insertion into or being appended to standard definition (SD) content segments. In other words, a mechanism is given to determine whether the primary content is standard or high definition content, and whether the secondary content to be inserted or appended thereto is standard or high definition content. If the primary content is standard definition content, the secondary content which will be presented therewith (e.g., is inserted therein) is down-converted to standard definition if necessary. As is well known, traditional SD content consumes about ¼ the bitrate/bandwidth of HD content, and hence the video resolution/clarity of the HD content versus the SD may be an undesirable artifact of mixing the two; resolution matching is useful in providing a satisfying user experience. For example, if the user is watching programming in SD, and HD advertisements are available, the HD advertisements are down-converted automatically. Resolution mismatches often result in problems such as macroblocking or audio drops. Alternatively, if the user is watching programming in HD, and SD advertisements are available, then the advertisements can be up-converted. As yet another alternative, SD programming can be upconverted to HD (or near-HD) in order to better match available HD advertising. These approaches may be applied to H.264/AVC, 3D, Silverlight, Apple, or any other media formats.
Replace Model—
• A first model for providing secondary content insertion is illustrated atFIG. 4. According to this model, a first segment of secondary content is used to replace another extant segment of secondary content. For example, the segments may be replaced one-for-one. Alternatively, the segments of inserted secondary content may be longer or shorter in length than those being replaced. Further, the number of secondary content segments inserted may be greater than or fewer than the number of replaced segments.
• The present secondary content segment replacement model may be utilized, in one embodiment, to replace secondary content targeted to a particular advertisement zone with secondary content targeted to another advertisement zone, national advertisements, and/or more specifically targeted advertisements (discussed below), although other purposes will be recognized by those of ordinary skill given this disclosure.
• The content segment replacement model may also advantageously be used to replace secondary content so that a user will receive the same secondary content no matter the device, location, or network from which the request originates. For example, a user requesting content from a mobile device to be delivered from an IP network will receive the exact same secondary content that the same user would receive if the request had originated from the user's STB at their home. In this manner, the MSO can ensure that demographic, psychographic, geographic, etc. information known about a subscriber is translated and utilized for the provision of content to the subscriber via any network and/or device in a consistent and predictable manner.
• As illustrated inFIG. 4, a primary content asset having secondary content inserted therein is generated for delivery to a first set of users. The asset is comprised of afirst content block402 comprised of a first primary content program (program A)406 divided into segments. In the illustrated embodiment, the primary content406 is divided into three segments (406a,406b,406c), but other numbers and division schemes may be used. The primary content406 is separated by secondary content segments (Content Asset B408 and Content Asset C410). As shown, the first segment ofprimary content406aand the second segment ofprimary content406bare separated by the first secondary content asset (Content Asset B)408; the second segment ofprimary content406bis separated from the third segment ofprimary content406cby the second secondary content asset (Content Asset C)410. Thecontent block402 is specifically generated to be provided to the first set of users. That is to say, the secondary content asset B and content asset C are specific to the first set of users according to e.g., demographics, geography (such as by advertisement zones, zip code, area code, etc.), psychographics, etc.
• When a user not belonging to the first set of users requests program A, the secondary content inserted therein is evaluated by a dynamic secondary content insertion application (e.g., an application running on one of the aforementioned management entities such as theADM220,ADS222, and/or CM224) to determine whether it is appropriate for transmission to the requesting user. The determination may be based on at least one of: (i) user demographics, (ii) user geographic location, (iii) advertisement zone, (iv) user psychographics, or (v) other information known about the requesting user, their present context, or the requesting device. This may be accomplished by comparing metadata or other descriptive information relating to the secondary content to information known about the requesting user (information obtained from the headend), or the requesting device. From a VOD perspective, the information about the subscriber is in the illustrated embodiment sent with the advertisement decision request. The advertisement decision manager can use that information to best determine what secondary content to insert (e.g., what advertisement to play). If the secondary content assets B and C are both appropriate for delivery to the requesting user, the asset it provided “as is” (with no changes).
• If it is determined that one or more of the secondary content assets (Content Asset B408 and/or Content Asset C410) provided in thecontent block402 are not targeted or otherwise suitable for delivery to a subsequent requesting user, the unsuitable secondary content is removed (such as by “ranging out” the segment of content in question), and new secondary content is placed in the content block in its place, thereby creating asecond content block404 comprising the original primary content406, having one or more new secondary content assets (such asContent Asset L412 and/or Content Asset M414) inserted therein. The process of ranging out may include for instance commands indicating “play from here-to-here in content X but not from there-to-there”, “play this part of content Y instead in the there-to-there part of X”, and so forth. These instructions may be performed by e.g., the ADM as part of an advertisement decision. In one embodiment, the secondary content is chosen for insertion by theADS222 andCM224. The dynamic secondary content insertion application (discussed below) running at theADM220 is responsible for removal of the unsuitablesecondary content assets408,410 and/or for insertion of the secondary content assets selected for replacement by theADS222 andCM224. Alternatively, the computer application(s) required for secondary content removal and/or insertion may be run at e.g., an entity of theBMS212, thecontent server206, or other headend entity discussed herein.
• The VOD system is responsible for preparing content for delivery (e.g., making the content appear acceptable). The VOD system functions as a splicer in an on-demand fashion. The ADM (which may be part of the VOD platform) is functionally responsible for knowing detecting a “trigger”, such as a session setup, and obtaining a decision or set of decisions about what advertisement or set of advertisements to play and where they go. Once the decision set is established the ADM can work with the VOD system to make the stream appear as it is supposed to by playing segments of one or more pieces of content out as a continuous stream.
• If the replacement secondary content segment (such asContent Asset L412 and/orContent Asset M414 ofFIG. 4) is shorter than the original secondary segment which it replaces, (such asContent Asset B408 and/orContent Asset C410, respectively), the primary content segment scheduled to follow the secondary content will play immediately following completion of the replacement content. Suppose for exampleContent Asset B408 is to begin at 1:30:00 and run to 1:33:15 relative the beginning of thefirst content block402. Suppose then, that the dynamic secondary content insertion computer application determines that Content Asset B408 (having a total running time of 00:03:15), is to be replaced by Content Asset L412 (having a total running time of 00:02:54). WhenContent Asset B408 is replaced,Content Asset L412 begins at 1:30:00 and runs to 1:32:54. In this instance, thesecond segment406bof the primary content406 as presented in thesecond content block404 will begin immediately afterContent Asset L412 ends e.g. at 1:32:54 (as opposed to starting at 1:33:15 as it would in the first content bock402). Subsequent content blocks or segments are therefore shifted forward in time so as to make them contiguous with any inserted secondary content.
• If the replacement secondary content (such asContent Asset L412 and/orContent Asset M414 ofFIG. 4) is longer than the original secondary content segment which it replaces, (such asContent Asset B408 and/orContent Asset C410, respectively), the primary content segment scheduled to follow the secondary content will play immediately following completion of the replacement content. Suppose for exampleContent Asset C410 is to begin at 1:30:00 and run to 1:33:15 relative the beginning of thefirst content block402. Suppose then, that the dynamic secondary content insertion computer application determines that Content Asset C410 (having a total running time of 00:03:15), is to be replaced by Content Asset M414 (having a total running time of 00:03:30). WhenContent Asset C410 is replaced,Content Asset M414 begins at 1:30:00 and runs to 1:33:30. In this instance, thesecond segment406bof the primary content406 as presented in thesecond content block404 will begin immediately afterContent Asset M414 ends e.g. at 1:33:30 (as opposed to starting at 1:33:15 as it would in the first content bock402).
• Referring now toFIG. 4a, amethod420 is given for performing the content replacement such as that discussed above with respect toFIG. 4. As illustrated, perstep422, afirst content block402 is provided to at least one first user. In one example, thefirst content block402 comprises primary content (Program A)406 having secondary content assets A408 andB410 inserted therein.
• Next, perstep424, a request is received from a second user for the primary content (Program A)406 at theDNCS218. Perstep426, the user must be authenticated in order to receive content. In one embodiment, the entitlements of the user to receive requested content are determined utilizing the systems and methods discussed in co-owned, co-pending U.S. patent application Ser. No. 12/536,724 filed on Aug. 6, 2009 and entitled “SYSTEM AND METHOD FOR MANAGING ENTITLEMENTS TO DATA OVER A NETWORK”, previously incorporated herein by reference in its entirety.
• In response to receiving the request, the dynamic secondary content insertion application determines whether the secondary content residing within thefirst content block402 should be replaced (step428). The determination of whether the secondary content should be replaced is based on, in one embodiment, the extent to which the secondary content is appropriate for the specific requesting subscriber and/or device. For example, secondary content advertising ski equipment may not be necessary and/or suitable for playback to devices located in e.g., Miami, Florida. In another embodiment, the determination may be based on whether the secondary content has “expired”. For example, certain secondary content may be directly related to a current event, a time of year, or may be otherwise in appropriate if not viewed by users within a given time frame. Such secondary content will therefore be replaced according to the methods discussed herein.
• The determination of whether the secondary content is appropriate may also be based on the context of the primary content with which it is associated. For example, the methods and apparatus discussed in co-owned, co-pending U.S. patent application Ser. No. 11/441,476 filed on May 24, 2006 and entitled “SECONDARY CONTENT INSERTION APPARATUS AND METHODS”, which is incorporated herein by reference in its entirety, may be utilized to provide dynamic secondary content insertion (e.g., replacement of dated or geographically inappropriate advertisements or promotions), and thereby allow the MSO or other network operator to adjust the secondary content to make it more applicable to the remote user's context (e.g., location, hardware/software environment, date/time, etc.).
• If the dynamic secondary content insertion application determines that the secondary content does not need to be replaced, thefirst content block402 is provided to the second user (step430). However, if the dynamic secondary content insertion application determines that the secondary content in thefirst content block402 should be replaced, then, perstep432, the secondary content is identified and replaced. In one embodiment, the secondary content is identified by the aforementioned dynamic secondary content insertion application via a header or metadata associated with the content. Once identified, the secondary content may be removed, and replaced by other secondary content.
• TheCM224,ADS222 andADM220 cooperate to select secondary content for insertion. In one embodiment, the content is selected from a playlist of available secondary content targeted specifically to the user and/or the device. The playlist may be created by theADM220 in response to receiving a message from theprimary content server206 that includes information identifying a subscriber (such as by subscriber account, device identification, etc.), and which may be made anonymous (i.e., specific to that user, but the identity of the user being unknown). The information identifying the subscriber may then be correlated to records in a data warehouse (not shown) which indicate various demographic (e.g., age and gender), psychographic (e.g., personality, values, attitudes, interests, or lifestyles), firmographic (e.g., industry, seniority or functional area), geographic (e.g., zip code, area code, or advertisement zone), and/or behavioral (e.g., usage rate or loyalty) variables associated with the given subscriber or group of subscribers. Information regarding the device from which the subscriber request was received (e.g., MAC address, IP address, configuration data, etc.) may also be collected and utilized. TheADM220,ADS222, and/orCM224 may then use the information to select appropriate (e.g., targeted) secondary content for the playlist, and then make insertion decisions from the playlist. Various business-related rules for this determination are discussed herein below. For example, which one(s) of the secondary content are inserted may be dependent on one or more factors relating to the primary content, the subscriber, the type of delivery requested, etc. The insertion of the selected secondary content (as replacement content) creates a second content block404 (comprising the new secondary content and previously referenced primary content (Program A)406).
• Next, perstep434, thesecond content block404 is provided to the second user.
Fill Model—
• FIG. 5 illustrates another model for secondary content insertion according to the present invention.
• The secondary segment fill insertion model may advantageously be used to insert secondary content into primary content which might not otherwise have secondary content inserted therein, and/or to increase the frequency of inserted secondary content (or move secondary content around within the primary content). In this manner, a user receiving primary content (such as via a network other than the traditional HFC network) at devices located within the user's home may additionally receive secondary content, including secondary content specifically directed to the user and/or device. For example, a user requesting a movie on-demand to be delivered over an IP network to their laptop computer will, according to the insertion methods discussed herein, receive the movie with secondary content inserted therein or associated therewith. In one variant, the secondary content is the same secondary content that user would receive if the request had originated from the user's STB at their premises. In this manner, the MSO can ensure that demographic, psychographic, geographic, etc. information known about a subscriber is translated and utilized for the provision of any content to the subscriber via any network and/or device. The fill insertion model further allows for secondary content insertion into long form content.
• In the model ofFIG. 5, one or more segmented secondary content assets (e.g.,Content Asset B510 and/or Content Asset C512) are inserted at splice points506a,506bin the primary content (Program A508) stream.
• A splice point is a location in a bitstream that provides an opportunity to splice. It is an attribute of an individual PID stream, not of a program; each PID of a program has a splice point which corresponds to each splice point in the PCR_PID. A splice point is marked by syntax in a transport packet. The “point” refers to an imaginary point between two packets of a PID stream. The splice points may be seamless, therefore requiring the program stream be encoded with buffer delay at the splice point, or non-seamless.
• The splice points may be predetermined by the primary content provider, or may be determined by the MSO or other network controller according to one or more business rules. Splice points may be correlated to events within the program itself (e.g., at logical pauses, breaks, or changes of scene), or have no correlation whatsoever. Splice Points may also occur at irregular intervals, or alternatively, at constant intervals. For example, secondary content (such as Content Asset B) may have a splice point at both its beginning and end. Since splice points merely represent opportunities to splice, the dynamic content insertion application of the present invention may insert splice points regularly (e.g., once every second, or once every GOP), thereby enabling theCM224,ADS222 andADM220 to insert secondary content at any of the splice points which are determined to be appropriate.
• In the illustrated example, an uninterrupted primary content asset (Program A)508 is provided as afirst content block502. The uninterrupted block comprises primary content only and does not have secondary content inserted therein. However, it is appreciated that in an alternative embodiment, the content block may be received as an interrupted block (i.e., a content block having one or more secondary content insertion points therein). If the dynamic secondary content insertion application determines that secondary content should be inserted, as illustrated inFIG. 5, secondary content assets (e.g.,Content Asset B510 and/or Content Asset C512) are inserted therein. As shown,Content Asset B510 is inserted intoProgram A508 at afirst splice point506a, thereby creating first andsecond program segments508a,508b. A third program segment508eis created by the insertion ofContent Asset C512 at asecond splice point506b. In this manner, the programming content ofProgram A508awill play out to a user, followed byContent Asset B510; immediately following the termination ofContent Asset B510,Program A508bwill continue where it left off prior to the switch.
• FIG. 5aillustrates anexemplary method520 for secondary content insertion according to the fill model discussed herein. As shown, perstep522, a request for primary content is received from a user at theDNCS218. Next, atstep524, it is determined whether the user is entitled to receive the content requested. In one embodiment,step524 is determined utilizing the systems and methods discussed in co-owned, co-pending U.S. patent application Ser. No. 12/536,724 filed on Aug. 6, 2009 and entitled “SYSTEM AND METHOD FOR MANAGING ENTITLEMENTS TO DATA OVER A NETWORK”, previously incorporated herein by reference, although other approaches may be used as well.
• Atstep526, the dynamic secondary content insertion application determines whether secondary content should be inserted into the requested primary content. If it is determined that secondary content does not need to be inserted, perstep528, the uninterrupted primary content block (first content block502) is provided to the user. Alternatively, if it is determined that secondary content should be inserted, then, perstep530, secondary content is identified and inserted at one or more splice points506 in the primary content.
• In one embodiment, secondary content for insertion is identified via cooperation of theCM224,ADS222, and ADM220 (discussed elsewhere herein). The dynamic secondary content insertion application provides information to the aforementioned entities regarding the number of available splice points (506a,506b) in the requested primary content. In one embodiment, these splice points are created by the dynamic content insertion application. For example, the application may createsplice points506a,506bat half hour intervals in the primary content, Program A406. TheCM224,ADS222, andADM220 may then use individual ones of these splice points to insert one or more secondary content assets.
• Secondary content may be selected from a playlist of available secondary content targeted specifically to the user and/or the device. The playlist, in this embodiment, is created by theADM220 in response to receiving a message from theprimary content server206 having information identifying the requesting subscriber (such as by subscriber account, device identification, etc.) contained therein, and which may be made anonymous as previously described. The information identifying the subscriber is correlated to data warehouse (not shown) records which indicate various demographic, psychographic, firmographic, geographic and/or behavioral variables, etc. attributed with the given subscriber; other information regarding the devices may also be derived and utilized, as well as context information relating to the user (or the primary content itself). For instance, the user may have different usage models (e.g., “Work”, “Home”, etc.) corresponding to different contexts; the secondary content selected for insertion in these different use contexts may be different.
• TheADM220,ADS222, and/orCM224 use the subscriber (and/or device or context) specific information to select appropriate (e.g., targeted) secondary content for the playlist, and then make insertion decisions from the playlist. The insertion decisions may be based on various business-related rules as will be discussed elsewhere herein. For example, which one(s) of the secondary content are inserted may be dependent on one or more factors relating to the primary content, the subscriber, the type of delivery requested, the target device, etc.
• Insertion of the secondary content (step530) results in the formation of a second content block which is, perstep532, provided to the requesting user.
Additive Model—
• FIG. 6 provides yet another model for secondary content insertion according to the present invention.
• The secondary content additive insertion model may advantageously be used to add or insert secondary content as needed. The additive insertion model can be used to insert secondary content in a non-disruptive fashion into primary content which might not otherwise have secondary content inserted therein, and/or to increase the frequency of inserted secondary content such as according to user initiated interruptions. In this manner, a user receiving any content, on any device, in any network via and from any location may receive secondary content, including secondary content specifically directed to the user and/or device, at various points during the playback of content without disrupting the playback of the requested content in the manner the user intended. For example, a user requesting a movie on-demand over an IP network for delivery to their laptop computer may receive the movie with secondary content being inserted ahead of and behind the movie playback. Additionally, secondary content may be provided at one or more instances where that user pauses, stops, fast-forwards, and/or rewinds the playback of the movie content.
• In one variant, the secondary content is the same secondary content that user would receive if the request had originated from the user's premises STB. In this manner, the MSO can ensure that demographic, psychographic, geographic, etc. information known about a subscriber is translated and utilized for the provision of any content to the subscriber via any network and/or device in a consistent and predictable manner.
• As illustrated inFIG. 6, one or more segmented content assets are combined dynamically. New secondary content is placed at the beginning (such as Content Asset P608) or at the end (such asContent Asset Q610 and Content Asset Z612) of a segment of primary content (such as Program A606).
• In the embodiment ofFIG. 6, the determination to insert secondary content is made “on the fly”. For example, a user viewing primary content may elect to pause or otherwise stop the program midstream (including for fast-forwarding, rewinding, or otherwise manipulating the content). In such a situation, the dynamic secondary content insertion application (and headend entities in association therewith) immediately determines whether to insert one or more secondary content assets therein.
• According to one embodiment of the additive model, secondary content assets are placed into a playlist. For example, a single playlist can be created which is utilized for secondary content insertion regardless of the primary content and/or requesting devices. Alternatively, various playlists may be created; individual ones of the playlists may be created (e.g., as primary content is requested), based on information contained in the request and/or information regarding the requested content or requesting user/device, or their context. For example, the genre of the selected primary content may be used as a basis for selecting secondary content to add to a playlist. Alternatively (or in conjunction), metadata associated with the requested content may include descriptions of various aspects or attributes of the requested content, various segments thereof (akin to a “scene” approach in prior art DVDs), etc. For instance, metadata may indicate that a given requested movie has: (i) one or more car chase scenes; (ii) one or more romantic scenes; (iii) one or more airport-related scenes, and so forth. A playlist incorporating secondary content (e.g., advertising) relating to one or more of these topics (i)-(iii) could then be generated. Where contextual synchronization is possible (e.g., content references or splice points exist within the primary content associated with the various scenes having the aforementioned topical content), the playlist may be structured so that only certain advertisements are placed at certain points, so as to have contextual relevance. For instance, the aforementioned car chase scene may begin at a first time, and end at a second time, and have 3 splice points or content references associated therewith. Only advertisements contextually related to car chases (e.g., for sports cars, high performance tires, fuel, etc.) would be inserted at any of those three points (or any time coordinates between the start and end points) if the opportunity arose, such as a user pausing during the car chase scene and then restarting play.
• The playlist, in another embodiment, is arranged according to a hierarchy. In other words, secondary content associated with certain sources is prioritized over other secondary content, in order to e.g., effect one or more business goals. For example, secondary content sources having paid higher premiums may have the secondary content associated therewith favored in the playlist (such as by being prioritized and/or placed more often therein) over those associated with other secondary content sources. As another option, the performance history of a given advertisement may be considered when ranking for the hierarchy; e.g., an advertisement that has experienced less pauses or tune-away events than another may be placed higher up within the hierarchy than the other advertisement.
• The playlist may comprise metadata enabling the dynamic secondary content insertion application to locate and insert the identified secondary content assets. Alternatively, the playlist may comprise links to the content associated therewith.
• In another embodiment, the asset playlist comprises an ordered list of segments, with each segment describing a range within a piece of content. The playlist according to this embodiment comprises both primary and secondary content. As will be discussed in greater detail below, in the instance the insertion of a particular secondary content asset fails, the entire playlist does not fail, but rather proceeds to display the next asset (whether primary or secondary content).
• According to the present invention, the aforementioned playlists may be created on-the-fly, based on the settings of the on-demand service and addressability parameters. Once the addressability parameters are created they are assigned they quickly associated with a session at session setup time in order to assist in the decision making of an advertisement decision.
• There are often adverse effects to the end-user if there are significantly different bit rates. Further, from a resource management perspective, it is difficult to have predictive knowledge of available bandwidth if the streams are constantly varying. In one embodiment, these adverse effects are avoided by capping the bitrates of the segments of a playlist at the highest bit rate so that from a planning perspective, it can be managed effectively.
• Additionally, secondary content may be inserted at the beginning and/or ending of the playback of the selected primary content according to the additive model. Thus, the dynamic secondary content insertion application supports dynamic insertion of content segments at the beginning and/or at the end of another segment (including other secondary content segments). The secondary content may be inserted immediately, or when the user resumes playback of the primary content.
• Referring now toFIG. 6a, oneexemplary method620 for secondary content insertion using the additive model is given. As shown, perstep622, a request for primary content is received. In one embodiment, the request comprises a request for VOD content from a user terminal. The request may be received at theprimary content server206 via theDNCS218.
• TheDNCS218 receives a message indicating the entitlements of the requesting subscriber to view the requested content in order for the content to be provided thereto. In one embodiment, this is accomplished via the “entitlements” approaches discussed previously herein.
• As discussed previously, theprimary content server206 may, in response to receiving the request, send a message to theADM220 thereby triggering the creation of a playlist of secondary content (step624). The message identifies the subscriber (such as by subscriber account, device identification, etc.), e.g., anonymously in order to enable the entities charged with identifying secondary content (e.g., theADM220,ADS222, and/or CM224) perform the selection based on what is known about the subscriber (such as by querying a data warehouse having records indicating demographic, psychographic, firmographic, geographic and/or behavioral variables) and/or the requesting device.
• Perstep626 of the method, the dynamic secondary content insertion application determines whether content will be inserted at the beginning of play out of the requested primary content. Various business-related rules for this determination are discussed below. For example, whether secondary content is inserted may be dependent on one or more factors relating to the primary content, the subscriber, the type of delivery requested, the requesting device, the user context, etc. The secondary content may comprise for example advertisements, which are inserted at the beginning of the primary content. If it is determined that secondary content should be inserted at the beginning of play out of the requested content, then perstep628, at least one of the secondary content assets from said playlist is added ahead of the beginning of the primary content and, perstep630, the secondary and primary content are provided to the requesting user (the secondary content being inserted so as to play out prior to play out of the primary content). Alternatively, if it is determined that secondary content will not be inserted at the beginning of play out of the primary content, the primary content is merely provided to the user (step632).
• In either instance, during the playback of the primary content, a pause or stop command is received. The pause or stop command may be received from a user, such as for example by the user pressing a “pause” or “stop” button or function key on the user's remote control device associated with the display device for playing out the primary (and secondary) content, and/or on the display device itself.
• A pause or a stop command may also be embedded within the primary content, such as at the end of the content or elsewhere therein (e.g., for a preprogrammed intermission). Hence, when the embedded command is reached, a signal is automatically generated and sent to the dynamic secondary content insertion application (e.g., running on one or more of themanagement entities220,222,224,210,212). When the pause or stop command is received, the dynamic secondary content insertion application determines whether secondary content should be inserted (step636).
• If it is determined that secondary content is not to be inserted, then perstep642, the primary content will resume play out if any portion of the primary content remains to be played. In one embodiment, the play out of the remaining portion of the primary content does not begin until a signal is received to do so. For example, the user may select a “play” button or function key on his remote control device or display device, thereby indicating that the user is ready to resume viewing the primary content.
• Perstep638, secondary content from the playlist is inserted at the pause/stop command if the dynamic secondary content insertion application determines that content should be inserted. Then, atstep640, the secondary content is presented to the user. Perstep642, subsequent to the presentation of the secondary content (step640), the primary content resumes play if there is any portion of the primary content which remains to be played. As discussed above, the primary content may resume upon user selection (such as via a “play” button on the user's remote control or display device). In another embodiment, the primary content may resume playback after a predetermined number of secondary content assets have completed play, or a prescribed time period has elapsed.
• Alongside the determination of whether secondary content will be inserted, the dynamic secondary content insertion application (or other entity in communication therewith) may also determine the number, types, and length of secondary content assets to be inserted. If a pause signal is received, the secondary content inserted may be a shortened form e.g., “clip” or in the form of a so-called “quick clip” (as discussed in previously incorporated co-owned U.S. Pat. No. 7,174,126 entitled “Technique for effectively accessing programming listing information in an entertainment delivery system”). If, on the other hand, a stop signal is received and/or if the program ends (and an automatic stop signal is received), the secondary content inserted may be longer format, and/or more than one secondary content asset may be inserted.
• Additional models for secondary content insertion may be utilized in conjunction with the present invention as well, the foregoing being merely illustrative of broader principles.
User-Based Selection
• In another variant of the invention, the aforementioned playlist of secondary content may be provided directly to the user. The user may then select the specific secondary content to receive from among the available secondary content. The playlist may be presented for example when a user selects a primary content element for viewing, or at some other time (e.g., when a user first starts up their CPE or display device). The selected secondary content will be displayed throughout the playback of the selected primary content at the appropriate secondary content insertion points (e.g., at the beginning, end, upon user-initiated interruption, or throughout according to splice points). Alternatively, the playlist may be presented at each instance of possible secondary content insertion, thereby ensuring that the viewer is present to view the presentation of the secondary content. In other words, when it is determined that secondary content should be inserted (either due to reaching one or more identified points in the content, or in response to the user's inputted commands), the user must physically select one of a plurality of possible advertisements. Optionally, the system may be configured to select an advertisement for the user if he/she does not make a selection within a prescribed time period.
Server—
• FIG. 7 illustrates andexemplary content server206 apparatus for use with the present invention. As illustrated, theserver206 generally comprises anetwork interface702 for interfacing with thecontent delivery network101, aprocessor704, astorage apparatus706 and a plurality ofinterfaces708 for communication with other entities of the content anddata distribution network200. The other entities with which thecontent server206 may be in communication as well as thecontent server206 itself with may be located at anetwork headend150. In one embodiment, as discussed above, thecontent server206 comprises a VOD content server.
• In the illustrated embodiment, the server comprises at least a dynamic secondarycontent insertion application710 running thereon. Although illustrated as a single application running on theserver206, it is appreciated that the foregoing dynamic secondary content insertion functionality may comprise a distributed application running on a plurality of entities in data communication.
• When a user establishes an on-demand session, or resumes a previous session, the server checks for updated content to place into the presentation stream. For instance, primary or secondary content may have a prescribed lifetime due to e.g., topical relevancy, and hence must be replaced periodically.
• Appropriate permissions may be required for the dynamic secondarycontent insertion application710 to assert controlling or management aspects with respect to the selection, insertion, and/or provision of secondary content to a client device. For example, the aforementioned management or control may require that the dynamic secondarycontent insertion application710 be given appropriate permissions from the MSO.
• In one example, the privileged or trusted application is configured to have appropriate permissions set up in the configuration tool to display playlist reports. In other words, theapplication710 is a privileged or trusted application which is able to access the configuration tool and direct the display of the playlist reports. The configuration tool is used to register primary content (such as on-demand content) for the herein-described dynamic content insertion. In one embodiment, the configuration tool is run at (or associated with) theADM220. The configuration tool allows or controls which decision services can make decisions for a given OD service. Accordingly, the dynamic secondary content insertion capabilities may be controlled or managed at theADM220 via the configuration tool. Playlist reports show what activity (sessions, session composition, playout results, performance characteristics etc.).
• The dynamic secondarycontent insertion application710 may also have appropriate permissions to set up theADS222,ADM220 and/orCM224, and direct theADS222,ADM220 and/orCM224 to select secondary content for insertion.
• The secondarycontent insertion application710 may use the configuration method specified on theAS214. In one embodiment, theAS214 specifies whether theADM220 will determine secondary content insertion, or whether metadata of the primary content will determine secondary content insertion.
• In operation, the dynamiccontent insertion application710 at theserver206 is in communication with theAS214 andADS222. When a user attempts to set up a session to receive primary content (such as on-demand content) from thecontent server206, theAS214 receives the user request and informs theapplication710. In response, theapplication710 queries theADS222 to determine the correct secondary content to associate with the requested primary content. TheADS222 returns at least one appropriate secondary content asset and/or a playlist of appropriate secondary content assets as discussed above to theapplication710. When theapplication710 receives at least information identifying appropriate secondary content for insertion, theapplication710 passes this information to back to theAS214. TheADS222 is the illustrated embodiment the “brains” for what secondary should be inserted; hence, it incorporates logic for making secondary content insertion decisions, although these may also be made in whole or part by other entities. In another embodiment, theinsertion application710 inserts the secondary content as appropriate, and transmits a content stream comprising the primary and secondary content to theAS214 for subsequent delivery to the user.
• Alternatively, the selection of secondary content for insertion may not be based on the primary content, but instead may be based on one or more other factors such as e.g., the subscriber or device identity, the advertisement zone, a time of day or time of year, or other business consideration as described elsewhere herein. Hybrids of the foregoing (i.e., considering both primary content and other factors) are also contemplated.
• Thus, in the case of an on-demand session, prior to setting up the session, theAS214 queries the dynamic secondarycontent insertion application710 to determine the correct secondary content asset(s) to associate with that session (e.g., based on the selected primary content, and/or other factor). TheADS222 then informs theapplication710 of the correct secondary content asset(s) for insertion at the beginning of playout of the selected primary content.
• Furthering the example, when a paused or stopped session is resumed (or when the pause signal is received), theAS214 queries the dynamic secondarycontent insertion application710 to determine the correct secondary content asset(s) to associate with that session. TheADS222 then informs theapplication710 of the correct secondary content asset(s) for insertion prior to resuming playback of the primary content after the pause or stop.
• In another embodiment, as discussed above, a playlist of one or more secondary content assets may be generated and distributed to thecontent server206 from which thecontent server206 or theADM220 may select secondary content for insertion. The playlist may be delivered at e.g., the initiation of the on-demand session (thereby obviating the need for multiple messages to be sent between these entities as the user pauses/stops playback of the primary content). Alternatively, upon each instance of resuming playback of paused or stopped primary content, a new playlist may be provided.
• An asset playlist of the types discussed herein above may include an ordered list of segments. The playlists may be created “on the fly” based on the settings of the on demand service and various addressability parameters. Exemplary addressability parameters may include e.g., demographics, geographies, or psychographies or basic attributes, such as “has internet” or “subscribes to HBO”. These parameters are weighted as part of an advertisement decision (and/or complex campaign management system). The addressability parameters are typically assigned to the subscriber and “picked up” at session setup time and used to embellish or enhance the request to place an advertisement. In one embodiment, the playlists may comprise only secondary content. Alternatively, the playlists may include both entertainment content (EC) and non-entertainment content (such as advertisements). In the instance both EC and non-EC are listed in a playlist, certain steps must be taken to avoid the entire playlist to fail if there is a failure of any one of the non-EC content elements fails. In one embodiment, this may be accomplished by utilizing at least one mechanism to ensure the bitrate of the content remains substantially constant (allowing for a reasonable level variation). The bitrate may be capped at the highest bitrate of the segments. In another embodiment, this is accomplished by validating each of the segments placed into a playlist and if any non-critical segments fail or do not validate, they are omitted from the playlist.
• It is appreciated that in some instances, secondary content may not be available for insertion at the time it is required. In one embodiment, if a secondary content segment is not available for insertion for any reason (e.g., it may have to be transrated/transcoded, may be damaged, the retrieval latency is too high, etc.), the primary content continues playing uninterrupted. Alternatively, a blank screen or frozen screen may be displayed, as in the case of secondary content insertion attempts at a pause/stop signal. If insertion of a secondary content segment is unsuccessful, the dynamic secondarycontent insertion application710 may reattempt the insertion a prescribed number of times or over a prescribed time interval. Alternatively, theapplication710 may forego reattempts, and default back to the aforementioned blank or frozen screen, or continue playback of the primary content. As yet another option, another secondary content element which is available may be substituted. Unsuccessful attempts to insert secondary content may be logged by the secondarycontent insertion application710, and reports generated from the failure logs if desired. Similarly, theapplication710 may be configured so that it will not attempt a reinsertion of the “failed” secondary content again without further operator intervention (i.e., sequester the failed content).
• In one implementation, theADS222 is able to process at least 100,000 queries per second from the secondarycontent insertion application710. Likewise, theapplication710 is also able to process at least 100,000 queries per second from theAS214, and process at least 100,000 responses per second from theADS222. This assumes that theAS214 can support 100,000 session set-up requests per second, and process at least 100,000 responses per second from the secondarycontent insertion application710. This capability allows the ADS/AS to service large portions of an MSO or other content distribution network from a single, centralized location if desired, and make secondary content selection and insertion effectively transparent to the user in terms of latency.
• In another implementation, when theADS222 receives a request for secondary content information, theADS222 responds to the request within 10 milliseconds and when theapplication710 receives a request from theAS214, it responds within 20 milliseconds. The expectation is that there will be minimal impact to the overall session setup process (i.e., little or no additional delay). Hence, these times are selected as the upper bounds of what would be considered “end-user impacting”.
• The secondarycontent insertion application710 is further responsible for directing the insertion of secondary content at user-invoked pauses. In one embodiment, theapplication710 establishes a time frame within which a secondary content asset should be output to a user after the user initiates the pause (such as via a remote control or display device). When the viewer re-initiates playback of the primary content, display of the inserted secondary content is terminated, and display of the primary content resumes. Alternatively, in another implementation of the invention, the secondary content is not inserted and played until the user initiates playback of the primary content.
• As noted above, the primary content may also be used in conjunction with so-called “start over” content (as described in previously incorporated co-owned, co-pending U.S. Patent Publication No. 2005/0034171 entitled “Technique for delivering programming content based on a modified network personal video recorder service”). As discussed therein, the start-over content may comprise primary content which was originally broadcast “live” to users with secondary content inserted therein. Start-over content uses local advertising zones (so called “ad zones”) to allow for targeted advertising to reach a specific, limited geographic area. Hence in the original broadcast, there are several defined breaks in the programming where local advertisements were inserted into the content stream. According to the present invention, these breaks may be reused for insertion of alternate secondary content by the dynamic secondarycontent insertion application710. The alternate secondary content assets may be selected for instance based on the aforementioned ad zones. For example, when the real time acquisition (RTA) entity starts, it determines the ad zone associated with the correct service group of the requesting user. This allows the correct zoned version of the recording to be played back, so the viewer sees the correct local secondary content. In this manner, national start-over content may be collected and distributed to users with local advertisements. In one embodiment, the RTA entity is disposed within the Mystro acquisition platform (such as the AS or Mystro entity) and is advantageously utilized to enable delivery of start-over and look-back content. The RTA schedules and creates content objects, and manages the content on the video platform as it relates to products like start over.
• A so called “parent zone” for each of the ad zones may be given to replace the ad zone of a request in instances where secondary content is not found for the ad zone from which a request for start-over content is received.
• A portion of the dynamic secondarycontent insertion application710 may be utilized for generating and delivering information to the users regarding the primary and secondary content. In one embodiment, this information is presented in the form of a banner which is displayed on the user's display device. The banner may e.g., be displayed across the bottom of the user's screen and/or may be opaque so as to avoid substantial disruption to the user's viewing experience. The banner may display the length of the session including all inserted or appended content segments. In other words, the secondary content insertion decisions may be made prior to any content is provided to the user; in this manner, the dynamic secondarycontent insertion application710 can calculate the total running time and, at time of presentation, present the running time in the banner. This embodiment may be useful, for example, to correct inaccuracies in the progress banner which result from the addition of secondary content to the entertainment content. Additionally, the method would be useful if the overall duration of what was communicated as part of the primary content is shortened. For example, suppose primary content is 1 hour in duration, and 2 minutes of “pre-roll” advertising are added and 5 minutes of “mid-roll” advertising are added, so that the total duration is 1 hour and 7 minutes. Unless the banner is updated, the user may mistakenly believe the content is 1 hour in duration (based on the primary content).
Exemplary Trick Mode Operation—
• The dynamic secondarycontent insertion application710 further cooperates with per-segment trick mode operations. In other words, theapplication710 uses a navigator application (e.g., a version of the Mystro Digital Navigator (MDN) and OCAP Digital Navigator (ODN) provided by the Assignee hereof) which supports trick modes within individual content segments. The secondary content inserted via theinsertion application710 also complies with the aforementioned trick mode requirements.
• Optionally, trick mode operation may be limited to certain times within each of the primary and/or secondary content segments. Accordingly, the primary and secondary content may include metadata describing time periods within the primary and secondary content during which trick modes are allowed. For example, one or more trick modes may be disabled throughout the entirety of secondary content playback, so as to prevent a user from fast-forwarding through commercials. One or more time-based segments may be associated with a single content asset. Time-based segment descriptors may then be used to determine which trick modes are allowed in each time segment associated with the asset. Alternatively, the content assets may not be associated with any time-based segments and/or descriptors. In one embodiment, the per-segment trick mode control information is made available to the client application (discussed below) in theCPE106 on a per-session basis. In other words, when a session is established for transmitting primary and secondary content to the user, the content insertion application gathers the trick mode control information, and provides this information to theCPE106. The user may also be informed of the trick mode control information associated with that session, such as via an information screen, window or banner display, which may be initiated with the user's input (e.g., only shows when the user attempts a prohibited function).
• The time-based segments associated with the content assets, in one embodiment, also include information describing the segments. For example, the descriptive information may include information indicating the segment type, segment controls (e.g., trick mode permissions), segment normal play time (NPT), start time (in milliseconds), and the segment duration (in milliseconds). The NPT is a time code in the MPEG stream that allows for synchronization.
• The segment types may be identified for example as primary content (e.g., entertainment content), secondary content (e.g., advertisement content), “pause advertisement” and/or other trick mode type (e.g., “trick mode enabled advertisement”, “trick mode disabled advertisement”, etc.). The aforementioned segment controls specify whether fast forward, rewind, pause, etc. functions are enabled or disabled for each time based segment. In one embodiment, certain trick mode operations are disabled or enabled depending on one or more characteristics of the requesting subscriber and/or device. For example, a subscriber having a lower tier or “basic” level subscription may be disallowed to invoke any trick mode operations (such as during primary and/or secondary content play). Alternatively, if a device is unable to perform the trick mode, the trick mode operation will be specified as disabled in the segment controls. However, it is appreciated that the stop function may be constantly enabled; i.e., there will be no disabling of the stop function for any segment.
• For on-demand assets, certain segment controls are not available; hence, they are listed as disabled in the segment controls. These include: “frame-by-frame forward”, “slow motion forward”, and “instant replay”.
• As discussed above, the segment control descriptors are configured to assign per-segment trick mode controls based on service level. Any asset associated with a given service that has not been assigned trick mode controls will have the trick mode controls of the service level applied thereto. Thus, unless an asset's trick modes are defined elsewhere, the trick mode functionality will be defined based on the service level of the requesting subscriber.
• In another embodiment, segment trick modes are assigned on a per-product basis. All the assets associated with a given product (such as MOD, SVOD, FOD, etc.) are given the same trick mode control profile (e.g., the set of trick modes enabled and/or disabled).
• The segment trick modes may also be applied on a per-provider basis. All assets from a given provider may be given the same trick mode control profile.
• In yet another alternative, the trick mode controls may be established on a per-asset (e.g., per primary content element, such as a movie) basis. That is to say, each asset may have a different set of enabled/disabled trick modes regardless of the product, provider, etc. In this manner, different assets associated with the same service, product, or provider may have different trick modes enabled for different assets associated with that service.
• A hierarchy may also be established, by which it is determined which trick mode profile will control for a given asset. In other words, in certain instances, a set of trick modes may be associated with the requesting subscriber's subscriber level, further trick mode controls may be established based on the provider, type, service or other characteristic of the asset. In one embodiment, the asset-based trick mode controls take precedence over the service level controls. If no asset-based trick mode controls have been applied to a particular asset, the service level segment trick mode controls are utilized. If no service level segment trick mode controls have been assigned to the asset, then all trick modes may be enabled for example, or a default profile having some restrictions may be applied. This hierarchy can also be applied only for restrictions; i.e., if no trick mode function restrictions are applied at the asset level, the service level is checked. If no segment trick mode controls have been assigned to an asset, then a default profile enabling all trick modes is utilized. It is appreciated that other default profiles may be utilized as well, including profile having one or more disabled trick modes. If an asset is associated with a per-segment trick mode descriptor which has been assigned by theADS222, then this descriptor will in one variant take precedence over any asset- or service-level descriptors.
• A “forced service level override” function may be assigned per-asset, and defined in the asset level trick mode controls. The forced service level override function identifies whether the asset level trick mode controls are able to take precedence over the service level controls.
• As will be discussed in greater detail below, an application running at the client device is configured to receive and honor the per-segment trick mode controls. As noted previously, if a particular asset is not associated with any time base segment descriptors, then a default trick mode profile is utilized (in one embodiment enabling all trick modes).
• A given session may utilize more than one time-based segment. In such an instance, it is appreciated that if a given trick mode is disabled in any one of the time base segment descriptors in the session, the trick mode may be disabled for the all of the segments in that session. For example, a session is associated with three time based segment descriptors, and fast forward is disabled in one of those segments then fast forward is disabled for the entire session. Hence, a “most restrictive” type of model is applied, wherein the most restrictive policies associated with one segment are applied to all segments, so as to maintain a consistent user experience. It is noted, however, that a “least restrictive” model may also be applied if desired (i.e., if one of the three aforementioned segments is not restricted compared to the other two, the least restrictive policy may be extended to the other two segments, again maintaining consistent user experience.
• If fast-forward is enabled for a given segment (which may include various levels or speeds of FF, such as “slow FF”, “fast FF”, and “skip FF” which provide progressively faster capabilities), the user is able to fast-forward the content associated with that segment, and/or jump forward through the content associated with that segment. If fast-forward is disabled for a given segment, then the user is not provided such capability.
• If rewind is enabled for a given segment (which again may have multiple levels or speeds), the user is able to rewind the content associated with that segment, and/or jump backwards through the content associated with that segment. If rewind is disabled, then the user is not provided these capabilities.
• If pause has been enabled for a given segment, then the user is allowed to pause the playback of that session during the segment where pause is enabled. If pause is disabled, the user is not able to pause the playback of the session. If the user invokes the pause function during playback of the session, the user is presented in one embodiment with several options including at least the ability to (i) resume playback of the session from the pause location, (ii) exit the session, and/or (iii) re-start the session from the beginning (where possible).
• The stop function enables a user to stop the playback of a session. In one embodiment, the stop function is always enabled. When the stop function is invoked by the user, the user is in one embodiment presented with several options including the at least the ability to (i) resume the playback of the session (if possible), (ii) exit the session, and/or (iii) re-start the session (where possible). If a user has stopped the playback of a session during a segment that has the pause function disabled, then the user is not presented with an option to resume the playback of that session. This requirement ensures that the stop/resume combination cannot be used as an alternate way to access the pause functionality during segments when pause has been disabled.
• If the user attempts to invoke a trick mode (such as fast forward, forward jump, rewind, backward jump, etc.) which is disabled, the user will be presented an on-screen indication that the selected trick mode is not allowed. In one embodiment, the on screen indicator is presented as a banner display or window. Alternatively, the indicator maybe displayed apart from the banner, but for the duration of the channel banner display timeout. There is no on-screen indication when a user invokes a trick mode which is enabled, although such display can be included if desired.
• If the user tunes away from an in-progress on-demand session playing on a dedicated on-demand channel (e.g., selects another numerical program channel via the EPG/remote), then the session is paused, and the standard on-demand session pause timeout parameters are applied. The pause timeout parameters are configurable, and in one embodiment are set to 20 minutes. If the user then returns to the dedicated on-demand channel while the session is still paused, the user is presented with the option to resume playback of the session. If the session pause has timed out, then if the user returns to the dedicated on-demand channel, the user is presented with a standard entry screen for that dedicated on-demand channel.
Data Collection
• As viewers interact with on-demand programming, events such as remote or CPE button presses or function invocations are captured. To accomplish this, the end-user's interactions with the CPE client software are communicated to the VOD system; the VOD system reports on a per-session basis these user events. Each user event is in one embodiment referred to as a placement status events (PSN).
• The captured information is transmitted to one or more of the above-referenced data collection entities, and may be used later in report generation, and/or to assist in selecting content for insertion. For example, one or more patterns regarding a user or device may be “learned” from the users' button presses and other actions taken with respect to content as discussed in co-owned, co-pending U.S. patent application Ser. No. 12/414,576 filed on Apr. 30, 2009 and entitled “RECOMMENDATION ENGINE APPARATUS AND METHODS”, which is incorporated herein by reference in its entirety. As discussed therein, the learned patterns can be used to identify and recommend content targeted to a particular user (or group of users) within a content-based network, such as a cable television or satellite network. Content may then be selected to align with a user's preferences (the latter which the viewer need not enter manually). In another aspect, the client applications discussed above are implemented by a network-based entity such as a hub or headend server adapted to perform the above-described functions for a variety of user profiles (e.g., individual user profiles, or user accounts) simultaneously.
• In one example, if it appears that the user often fast forwards through sports-related advertisements, but will view advertisements for family programming, a recommendation engine (not shown) will assist theADS222 in selecting content for insertion that is related to family programming and/or family related events (such as theme parks, children's or family movie trailers, etc.).
Targeted Secondary Content Insertion—
• As noted above, in one embodiment, inserted secondary content may be specifically targeted to the user, context, and/or device from which a request is received, as well as the primary content requested. Information may be obtained, for example, relating to the geographic location, advertisement zone, demographics, or psychographics of the subscriber. Information may be obtained regarding the geographic location, capabilities, etc. of the device as well. Still further, the secondary content may be logically related to the context of the primary content. For example, sports-related primary content may invoke the insertion of sports related advertisements. The user context may also be exploited; i.e., knowing that a user is at work or their primary home or their vacation home may each trigger selection of different secondary content.
• For example, the apparatus and methods discussed in co-owned, co-pending U.S. patent application Ser. No. 11/198,620 filed on Aug. 4, 2005 and entitled “METHOD AND APPARATUS FOR CONTEXT-SPECIFIC CONTENT DELIVERY”, which is incorporated herein by reference in its entirety, may be utilized consistent with the present invention. As discussed therein, contextually-related “secondary” content (e.g., advertising messages, useful informational links, etc.) may be provided in association with other primary content selected by the user. In one exemplary embodiment, the secondary content is selected at least in part based on metadata associated with the primary content. The metadata may be provided by, e.g., the content originator or the network operator, and is sent to a network entity (e.g., advertising server) which returns contextually specific advertising matching the search terms. In one variant, the search term is simply one or more keywords drawn from the metadata and used as an input to a search engine. In another variant, more sophisticated analysis of the metadata is performed so as to ostensibly reduce the number of irrelevant or marginally relevant “hits” returned by the search engine/advertising server.
• The apparatus and methods discussed in co-owned, co-pending U.S. patent application Ser. No. 11/441,476 entitled “SECONDARY CONTENT INSERTION APPARATUS AND METHODS”, previously incorporated herein, may be utilized to further provide secondary content insertion. As discussed therein, secondary content may be inserted dynamically (e.g., replacement of dated or geographically inappropriate advertisements or promotions), thereby allowing the MSO or other network operator to adjust the secondary content to make it more applicable to the remote user's context (e.g., location, hardware/software environment, date/time, etc.).
• Still further, the methods and apparatus discussed in co-owned, co-pending U.S. patent application Ser. No. 12/503,710 filed Jul. 15, 2009 and entitled “METHODS AND APPARATUS FOR TARGETED SECONDARY CONTENT INSERTION”, which is incorporated herein by reference in its entirety, may be utilized as well. This embodiment is particularly useful in targeting content to a set of subscribers, such as those serviced by a local service node. As discussed therein, content targeted to a particular audience within a content-based network may be identified and inserted. For instance, the content is identified by analyzing audience or viewer qualities (i.e., psychographic, geographic, or demographic, characteristic or classifications) at a particular insertion opportunity using an advertisement management system (and associated advertisement decision maker process). The audience information can in one embodiment be gathered in real-time directly from users' CPE (i.e., set top boxes, cable modems, PC, etc.), thereby allowing information to be gathered which is specific to actual content viewers. Historical or other information relating to particular subscribers (or subscribers in general, or even the broader general population) may also be utilized in characterizing an audience. The advertisement management system then uses the gathered audience information to correlate particular advertisements or other content thereto. In one variant, an algorithm is used to analyze audience qualifiers (i.e., attributes of an audience or its behavior), and determine the “proximity” of a given audience (e.g., that currently viewing a program where an impending placement opportunity will occur) to a set of audience qualifiers of a target audience of an advertisement. The placement opportunity can then be optimized for one or more variables (e.g., proximity, revenue, impressions, etc.) by selecting the best fitting advertisement for that opportunity.
• The aforementioned methods and apparatus can advantageously provide content across multiple delivery platforms utilizing substantially extant network infrastructure and components compatible with a number of different client device and delivery systems including both wired and wireless technologies.
• Subscriber privacy and anonymity is also optionally maintained via e.g., hashing or encrypting data relating to the CPE and/or subscriber (as discussed below), thus ensuring that stored data is not traceable to a specific user account. In alternative embodiments, only information designated by a consumer is eligible for content collection and/or analysis. In this manner, subscriber privacy is effectively safeguarded, and user control of their private information (including for example preferences or user profile) is protected as well.
• The primary and secondary content can also be manipulated to perform all relevant advertising formats and schemes (e.g., bookends, replacement, pause, telescoping, etc.) on the content transferred by the network or from other content source. See, e.g., co-pending and co-owned U.S. patent application Ser. No. 10/662,776 filed Sep. 15, 2003 and entitled “SYSTEM AND METHOD FOR ADVERTISEMENT DELIVERY WITHIN A VIDEO TIME SHIFTING ARCHITECTURE”, incorporated herein by reference in its entirety, which describes exemplary methods and apparatus for implementing the foregoing (and other) schemes and formats within the context of a content-based network.
Enhancement Model—
• In another embodiment, the primary content and/or secondary content discussed herein may comprise so-called “enhanced content” as discussed in co-owned, co-pending U.S. patent application Ser. No. 12/582,653 filed Oct. 20, 2009 and entitled “METHODS AND APPARATUS FOR ENABLING MEDIA FUNCTIONALITY IN A CONTENT-BASED NETWORK”, which is incorporated herein by reference in its entirety. As discussed therein, the secondary content and/or primary content may comprise one or more user-interactive media features or applications. In one particular implementation, various of the foregoing interactive “media” applications are disposed at one or more headend entities; also provided is a servlet application which facilitates communication between the various applications and one or more client applications resident on the user's premises system. In this manner, a user at his/her premises or client device, may access and interact with various ones of the applications in an integrated fashion.
• In another implementation, individual ones of the interactive applications are in communication with an internet (e.g., Internet) host server in order to obtain data therefrom via a gateway device located at e.g., the headend of the network. In other words, the gateway device requests and receives internet data and/or content from the host servers on behalf of the media application(s). The data and/or content is then processed as required and, via the servlet, delivered to one or more client devices. For example, the content may be de-encapsulated from a first container format, and re-encapsulated into a second format for delivery to the client device. The content may also optionally be transcoded and/or transrated if desired. The servlet application may serve as a proxy for various ones of the applications which utilize a different content format than the client device. The servlet application will refer the client device (such as by the SIP REFER method) to a media application which utilizes the same content format as the client device. For example, if the media application provides standard HTTP APIs, then the client device may communicate directly therewith.
• In another embodiment, one or more of the interactive media applications is configured to utilize the Enhanced TV Binary Interchange Format (EBIF). Further, the client application running on the client device(s) may comprise an EBIF user agent. The user agent enables a user of the client device to view and interact with various EBIF pages of the particular media application(s) of interest.
• One of the exemplary interactive media applications is a search application, which enables a user to search the internet for data relating to displayed program or advertising content. For example, the user may use the search application simultaneous with the playing of a commercial for a restaurant to find the nearest location and/or directions, or other information about the restaurant (such as reviews, Zagat™ rating, etc.).
• Another media application useful in various embodiments of the present invention is a real-time web-based micro-blogging application, which enables a user to post, view and navigate micro-blogs from the user's CPE (e.g., set top box or converged media device) simultaneously with viewing programming and advertising content.
• Yet another media application useful with the invention is a so-called “request for information” or RFI application. In one embodiment, the RFI application enables the user to select to receive additional information about a product or service, such as via a “telescoping” function discussed in co-owned, co-pending U.S. patent application Ser. No. 12/284,757 filed on Sep. 24, 2008 and entitled “METHODS AND APPARATUS FOR USER-BASED TARGETED CONTENT DELIVERY”, which is incorporated herein by reference in its entirety. As discussed therein, exemplary methods and apparatus are configured to correlate the content of the secondary content and the content of the contemporaneous primary content via metadata, thereby placing the advertisement or promotion “in context”. Additionally, the correlation may be “fine tuned”, such as based on the subscriber demographic data. At yet a further level of precision, the metadata in the primary content and/or secondary content can be provided with a timing index or other reference and further information (e.g., descriptive codes) that allow for precise placement of the secondary content within a program stream for maximum efficacy.
Anonymity—
• As noted above, certain collected data may be particular to or identified with a particular subscriber, user, or user device. Accordingly, such data may be anonymized by inter alia, the use of a cryptographic hash to protect the privacy of the identified subscriber, user, and/or device. In one embodiment, the techniques for providing anonymity utilizing a cryptographic hash described in U.S. patent application Ser. No. 11/186,452 filed Jul. 20, 2005 and entitled “METHOD AND APPARATUS FOR BOUNDARY-BASED NETWORK OPERATION”, which is incorporated herein by reference in its entirety, may be utilized in conjunction with the present invention. As disclosed therein, the identity of a CPE or subscriber is anonymized by using a cryptographic hash coupled with an optional “opaque” variable which carries information relating to the CPE of the hash with which it is associated. The hash and opaque variable frustrate de-encryption or reverse-engineering of the individual subscriber's identity or specific location. Alternative methods of providing anonymization may also be utilized consistent with the present invention.
Exemplary CPE—
• FIG. 8 is a block diagram of one exemplary embodiment of theCPE106 discussed above. In the illustrated embodiment, theexemplary CPE106 includes anetwork interface802, aprocessor804 and associatedstorage806, and a plurality of back end interfaces808 for communication with other devices.
• The illustratedCPE106 can assume literally any discrete form factor, including those adapted for settop/desktop, hand-held, or wall-mounted use, or alternatively may be integrated in whole or part (e.g., on a common functional basis) with other devices if desired.
• It will also be recognized that the CPE configuration shown is essentially for illustrative purposes, and various other configurations of theCPE106 are consistent with other embodiments of the invention. For example, theCPE106 inFIG. 8 may not include all of the elements shown, and/or may include additional elements and interfaces such as for example an interface for the HomePlug A/V standard which transmits digital data over power lines, a PAN (e.g., 802.15), Bluetooth, or other short-range wireless interface for localized data communication, etc.
• Thenetwork interface802 of the illustratedCPE106 receives content and/or data. In one embodiment, the network interface may comprise one or more RF tuners configured to receive content from anHFC network101. The RF tuner(s) may comprise traditional video RF tuner(s) adapted to receive video signals over, e.g., a QAM. For example, the RF tuner(s) may comprise one or more tuners, a demodulator, decryption module, and demultiplexer of the type well known in the art, although other configurations may be used. A wideband tuner arrangement such as that described in co-owned and co-pending U.S. patent application Ser. No. 11/013,671 entitled “Method and Apparatus for Wideband Distribution of Content” filed Dec. 15, 2004 and incorporated herein by reference in its entirety, may also be utilized, such as where the content associated with one or more program streams is distributed across two or more QAMs. Additionally, the RF tuner(s) may incorporate functionality to modulate, encrypt/multiplex as required, and transmit digital information for receipt by upstream entities such as the CMTS.
• Alternatively, thenetwork interface802 may comprise any other means for receiving content from a network. Digital data received via thenetwork interface802 may include for example MPEG-2 encoded programming data that is forwarded to a television monitor via a video interface. Programming data may also be stored on theCPE storage unit806 for later distribution by way of the video interface, or using a Wi-Fi interface, Ethernet interface, Firewire (IEEE Std 1394), USB/USB2, or any number of other such options.
• In another embodiment, theCPE106 may further comprise a cable modem (CM) of the type known in the art, including one or more tuners configured to tune to DOCSIS QAMs. In this fashion, and content or data normally streamed over the CM can be received and distributed by theCPE106, such as for example packetized video (e.g., IPTV). In accordance with the exemplary embodiment of the invention, the DOCSIS cable modem may also be utilized for delivery of traditional broadband Internet services. As discussed elsewhere herein, content and/or data sent to theCPE106 will only be presented to those subscribers having appropriate rights to receive the data/content.
• Programming and other types of data including pictures, video, music or MP3 files, software applications, metadata files, etc. may also be received by way of the various digital interfaces in theCPE106. These data may be stored locally (e.g., in the CPE storage unit806) or even on a device or network agent in communication with theCPE106, for later use by a user as is discussed in co-owned co-pending U.S. patent application Ser. No. 11/378,129 entitled “METHODS AND APPARATUS FOR CENTRALIZED CONTENT AND DATA DELIVERY”, previously incorporated herein.
• TheCPE106mass storage device806 of the illustrated embodiment comprises a Serial-ATA (SATA) or Ultra-ATA (also known as Ultra-DMA, or ATA-4/5/6/7) hard disk drive for the operating system and content storage of at least 500 GB, although higher capacities and even RAID arrays may be used for this purpose. TheCPE106 hard disk is preferably removable without the need for tools, and theCPE106 is also configured allow for an external USB (e.g., USB 2.0) drive or other easily removable storage device to be attached and automatically added to the existing storage. It will also be appreciated that USB keys of the type well known in the art can be used consistent with the USB port(s) of theCPE106, so as to make the data storage device highly mobile and of very small size.
• During operation of theCPE106, a client application810 (located in the storage unit806) is run on themicroprocessor804. Theclient application810 facilitates the secondary content insertion discussed herein by providing information regarding the subscriber/user and/or device to the insertion entities discussed above. For example, theclient application810 may provide subscriber account information upstream in order for the ADS22 (and other entities) to identify the subscriber and provide content based on what is known (at the headend) about the subscriber. In addition, theclient application810 may be configured to collect information regarding the user's actions with respect to content. For example, theclient application810 may record button presses, playback events, trick mode events, etc. and pass this information to theADS222 and other headend entities.
• In another embodiment, the aforementioned secondary content insertion entities (e.g.,ADS222, etc.) may provide the playlist of available secondary content and/or the secondary content itself directly to theCPE106 for storage thereon. Theclient application810 in this embodiment may be configured to dynamically cause insertion of the provided secondary content upon the occurrence of a particular event. For example, theclient application810 may insert secondary content when the user pauses or otherwise stops playback of requested content. Such mechanisms may utilize the methods discussed above with respect toFIGS. 6 and 6aabove. Theclient application810 may insert secondary content from the provided secondary content. Alternatively, theclient application810 may utilize metadata of the provided playlist to request secondary content for insertion from the headend; once received, theclient application810 may insert the content as discussed above.
• In one embodiment, theCPE106 may be further adapted to perform de-encapsulation/re-encapsulation of content where necessary as is disclosed in U.S. patent application Ser. No. 12/582,619 entitled “GATEWAY APPARATUS AND METHODS FOR DIGITAL CONTENT DELIVERY IN A NETWORK”, previously incorporated herein. In this embodiment, theCPE106 is adapted to processes content from a first media file container format to one or more second media file container formats which are compatible with theCPE106 capabilities or with the capabilities ofother CPE106 in communication therewith.
• In another aspect, theCPE106 of the present invention may be also compatible with the methods and apparatus disclosed in U.S. patent application Ser. No. 11/363,578 filed Feb. 27, 2006 and entitled “METHODS AND APPARATUS FOR SELECTING DIGITAL ACCESS TECHNOLOGY FOR PROGRAMMING AND DATA DELIVERY”, which is incorporated herein by reference in its entirety. Specifically, a plurality of CPE106 (electronic devices such as set-top boxes, PMDs, etc.) containing one or more hardware and software functions or modules are used; the hardware and software functions/modules of thedifferent CPE106 on the network contain various capabilities and options, including conditional access capabilities, video coding or compression capabilities, encryption schema, and network interfaces. These capabilities may be utilized by thecontent server206 as a basis for determining which conditional access, coding, encryption, and/or network interfaces to utilize for delivery of content to eachparticular CPE106. TheCPE106 of the present invention can accordingly be equipped with such capability if desired in order to, inter alia, profile theCPE106 for tailoring content or other functions (e.g., CA) to thatspecific CPE106 environment. For example, if the CPE106 (or any of its connected “client devices”) has only an MPEG-2 decoder, only MPEG-2 encoded content would be sent to that CPE106 (or passed on to the client devices), or alternatively the CPE or devices would obtain the necessary codec (e.g., MPEG-4 or Real) from another source, such as an MSO or third party.
Business/Operational Rules Engine—
• In another aspect of the invention, a so-called “rules” engine may be disposed at e.g., theADM220,ADS222,CM224,CPE106, or other location (e.g., rendered as one or more computer programs disposed thereon). This engine comprises, in an exemplary embodiment, one or more software routines adapted to control the secondary content insertion process in order to achieve one or more goals relating to operations or business (e.g., profit). Included within these areas are network optimization and reliability goals, increased maintenance intervals, increased subscriber or user satisfaction, increased subscription base, higher profit (e.g., from increased advertising revenues, more subscriber “views” of given content, higher data download speed, increased bandwidth and responsiveness to changing demands for bandwidth, reduction of undue QAM replication, and so forth.
• These rules may comprise a separate entity or process, and may also be fully integrated within other processing entities (such as the applications running on the aforementioned entities and/or the client application810), and controlled via e.g., a GUI displayed on a device connected to the relevant server or CPE. In effect, the rules engine comprises a supervisory entity which monitors and selectively controls secondary content insertion operation at a higher level, so as to implement desired operational or business rules. The rules engine can be considered an overlay of sorts to the more fundamental algorithms used to accomplish required network operation, such as IP address assignment, secondary content selection and insertion, statistical multiplexing, BSA switching, and so forth.
• For example, theADM220,ADS222,CM224 orCPE106 may invoke certain operational protocols or decision processes based on information or requests received from theCPE106, conditions existing within the network, demographic data, geographic data, etc. However, these processes may not always be compatible with higher-level business or operational goals, such as maximizing profit or system reliability. Hence, when imposed, the business/operational rules can be used to dynamically (or manually) control the selection and/or insertion of secondary content. The rules may be, e.g., operational or business-oriented in nature, and may also be applied selectively in terms of time of day, duration, specific local areas, or even at the individual user level (e.g., via specific identification of the CPE or client device via TUNER_ID, IP address, MAC address, or the like, or via a user-based login or “entitlements” profile).
• For example, one rule implemented by the rules engine may comprise providing secondary content from certain secondary content sources according to a tiered system. Secondary content under such an approach might be selected in part on the revenue such insertion will bring to the MSO based on the secondary content source.
• Alternatively, historical “performance” of a given secondary content element may be considered, irrespective of source. For instance, each of a plurality of secondary content sources may have playlists comprising several advertisements. However, the selection of a given advertisement from the playlist may also consider whether an advertisement has historically received a disproportionate number of tune-away or pause events during the playout thereof (i.e., indicating users are not interested in the advertisement).
• Other metrics of performance may be used as well, such as one relating to MSO revenue or profit per unit time of play. For instance, it may be that insertion of two (2) advertisements of 15 seconds each would (based on historical data) produce a greater revenue or profit for the MSO (or content source) than a single advertisement of 30 seconds.
• Two or more secondary content elements may also be selected in coordinated or “ganged” fashion so as to meet one or more desired business goals. For instance, in the case of the previous example of a primary content element (e.g., movie) having a car chase scene, it may be that there are splice points or insertion opportunities at either end of the segment containing the car chase scene. Hence, one secondary content selection model might comprise selection of two car-related advertisements for these two insertion opportunities, thereby sotensibly enhancing the contextual relevance of the advertisements to the primary content.
• As another example, the selection algorithms may be configured to purposely select, or purposely avoid, placement of two advertisements having a given commonality, proximate to one another in “advertisement space”. For example, the commonality may comprise a common actor or personality advertising different goods/services for a common source or advertiser. The commonality may also comprise the same goods and services from competing advertisers (e.g., the MSO way wish to avoid placing advertisements for competing cellular service providers one after the other).
• Moreover, it is appreciated that the “user” and “device” specific data previously referenced herein may also apply to multiple individuals, or organizations. For example, a device identification may relate to a DSTB or other CPE within a family premises having several individual family members associated therewith. Each of these family members may have different demographics, psychographics, etc., and hence the present invention contemplates that the CM or other supervisory/selection entity can be configured to construct advertising or promotional campaigns based on (i) two or more person as individuals, or (ii) on the entity in the aggregate. For example, a “family” or “company” profile may be constructed, which considers the various attributes, demographics, psychographics, etc. of the entity as a whole, or multiple sub-profiles for each of the individuals may be used. User-specific logins such as those described in co-owned, co-pending U.S. patent application Ser. No. 12/414,554 filed on Mar. 30, 2009 and entitled “PERSONAL MEDIA CHANNEL APPARATUS AND METHODS”, which is incorporated herein by reference in its entirety, may be used for this purpose; i.e., to specifically identify an individual within an entity, so as to tailor the secondary content for that individual (as opposed to the larger entity as a whole).
• It is also appreciated that the enhanced opportunities for targeted secondary content insertion described herein may be exploited by network operators or advertisers via a “network promotion” product or model. For example, clients of an MSO (e.g., studios, networks, advertisers, etc.) can utilize the foregoing content insertion tools (e.g., replacement, fill, and/or addition) to specifically target advertising or other secondary content based on the characteristics of the subscriber and/or the particular on-demand asset being viewed.
• Moreover, individual user devices associated with a common account may be used as the basis for selection and insertion. That is, knowledge of a particular requesting device may tell the CM, ADM, etc. what the context of a user is at the time of request. For example, a given subscriber account may have three (3) separate devices registered therein or associated therewith, such as (i) a DSTB; (ii) a 3G or 4G (e.g., WiMAX or LTE enabled) mobile smartphone; and (ii) a WiFi-enabled PMD. Origination of an OD content request via the smartphone or PMD (e.g., over a WiFi WLAN in communication with the subscriber's “home” cable or satellite network) may be used to determine that the subscriber has a “mobile” context (i.e., is not at their premises), and therefore may wish to receive, or can make best use of, a certain class of secondary content (e.g., advertisements related to mobility-related topics, such as on-line sources for directions, things having an “on-the-go” theme, travel topics, etc.). Conversely, where the request originates from that user's DSTB, the context may indicate that premises-related advertisements (e.g., home repair or upgrade, real estate purchase, major appliances, etc.) are more suitable or effective.
• The types or formats of secondary content to be inserted may also vary according to the status of the requesting subscriber and/or device (e.g., certain subscribers or classes of subscribers may receive upgraded content formats). As noted previously, these rules may be implemented at the device level (e.g., CPE106) or at theADM220,ADS222, orCM224. TheCPE106 may possess high definition (HD) decoding capability, for example, but programs rendered in HD would not be made available to such subscribers unless they met certain criteria (e.g., “premium” subscription, etc.). Similarly, if the subscriber did not possess a required codec, CA keys, or network interface, the download of this missing component could be controlled to only subscribers meeting certain criteria. In one embodiment, the business rules engine running on aprocessor804 of theCPE106 and/or at theaforementioned ADM220,ADS222, orCM224 implements these criteria.
• Many other approaches and combinations of various operational and business paradigms are envisaged consistent with the invention, as will be recognized by those of ordinary skill when provided this disclosure.
Alternate Delivery Paradigms—
• As previously noted, the concepts and apparatus described herein are readily extensible to other content delivery paradigms which provide content “on demand”, including without limitation: (i) “pay per view (PPV)”; (ii) content rental or purchase via mail or other tangible delivery platform (e.g., the prior art “Netflix®” service); and (iii) selection of a video for play via the Internet, such as via the “YouTube®” website.
• For example, typical PPV services offer customers the ability to tune into existing linear content broadcasts which begin at staggered times across various different program channels offered by the MSO. The user does not “demand” the content per se, but rather demands access to an existing asset stream. Since the content stream is ubiquitous and delivered identically and simultaneously to a plurality of different subscribers, the opportunities for targeted insertion of secondary content before or during the primary content stream play are limited; however, at the completion of the PPV stream, an insertion opportunity exists. In one approach, the user, content, or device-specific data is sent upstream to theADM220,ADS222, orCM224 upon PPV request. At a subsequent time, theADM220,ADS222, orCM224 uses the user-specific data to identify a targeted advertisement for delivery to the user immediately upon completion of the PPV movie (or even upon detection of a tune-away event received before completion of the PPV event, e.g., within one minute of the end of the program, when people normally tune away while the credits are being played). A brief user-specific “on demand” session is instantiated automatically, and the short advertisement played, but the session may be terminated if the user tunes away (or alternatively, the user may be “held captive” for the duration of the advertisement by preventing user termination of the session or tune-away, and then control subsequently restored when the advertisement has been completed).
• In terms is of content rental or purchase, user, context, or device-specific data may be used to select secondary content for inclusion within purchased or leased media delivered to the user. For example, in one such variant, user- (or premises) specific DVD or other physical media is dynamically generated and sent to a user. For instance, a user might access a media provider's Internet website via their cable or satellite modem (whether interactively, such as in the context of an IPTV scenario, or via traditional data channels), and select a title for delivery via “hard” media. The request may include information regarding the user, which can be used to access demographic, psychographic, etc. data relating thereto. Targeted secondary content can then be dynamically selected and inserted (“burned”) onto the DVD before shipment (e.g., in a just-in-time fashion), so that each DVD delivered to each customer is uniquely tailored to them in terms of secondary content (e.g., trailers, previews, advertisements, etc.).
• In another variant, the methods and apparatus described in co-owned and co-pending U.S. patent application Ser. No. 11/080,693 filed on Mar. 14, 2005 and entitled “METHOD AND APPARATUS FOR NETWORK CONTENT DOWNLOAD AND RECORDING”, which is incorporated herein by reference in its entirety, may be used consistent with the present invention. As described therein, extant high-speed network download and data recording technologies may be used to provide the network subscriber or other user the ability to timely and rapidly download new content such as a new-release movie or game, along with the ability to promptly reduce the downloaded content onto a desired medium (e.g., DVD). The downloaded content may include e.g., targeted secondary content selected and inserted according to the methods and apparatus discussed elsewhere herein. The provision of the new content for viewing can also be tied to a purchase of the content (or other commerce-based event), such as where the content is only delivered after the user agrees to purchase the content and record it onto a DVD or similar media. This capability provides a number of distinct advantages, including, inter alia: (i) the ability to sell the subscriber a movie or other title in an earlier window than would otherwise be available under prior art network content distribution paradigms; (ii) the ability to download a disk image to the customer's DVR hard disk or other storage device at a very high speed; and (iii) the customer's ability to run the downloaded content directly from their hard disk and also produce a fixed or erasable medium copy (e.g., DVD, memory stick, USB key, etc.), as desired.
• In terms of online (Internet) content demands, the MSO may utilize knowledge regarding a particular subscriber, account, device, use or content context, etc. to selectively insert advertising or other secondary content into the requested video. For instance, a user requesting to watch a YouTube video on their PC (or television monitor via, e.g., the methods and apparatus of U.S. Provisional Patent Application Ser. No. 61/256,903 entitled “METHODS AND APPARATUS FOR PACKETIZED CONTENT DELIVERY OVER A CONTENT DELIVERY NETWORK” previously referenced herein) will be identified as being a particular MSO network subscriber, and hence demographic, device, context, etc. information can be used to populate one or more insertion opportunities with targeted secondary content within the delivered IP transport of the primary content. For instance, in one variant, the secondary content is appended contiguously to the front or back of the requested video, akin to prior art video delivery windows now ubiquitous on the network. One salient distinction over these prior art approaches, however, is an explicit association between the requesting subscriber and particular demographics, psychographics, device contexts, etc. and the inserted advertising.
• In yet another embodiment, content providers which provide the content fixed a physical medium (such as the aforementioned Netflix system) may generate and re-use user-customized versions of the content. In other words, the content may be placed on a DVD or other fixed or transitory medium with secondary content inserted therein which is specific to (e.g., targeted to) a first user. Once the DVD is returned, the targeted DVD may be categorized based on e.g., demographics, psychographics, etc. and subsequently provided to a second user requesting the content who shares the demographic, psychographic, etc. of the first user. In this manner, multiple uniquely targeted content versions may be created and shared among a plurality of users.
• It will be recognized that while certain aspects of the invention are described in terms of a specific sequence of steps of a method, these descriptions are only illustrative of the broader methods of the invention, and may be modified as required by the particular application. Certain steps may be rendered unnecessary or optional under certain circumstances. Additionally, certain steps or functionality may be added to the disclosed embodiments, or the order of performance of two or more steps permuted. All such variations are considered to be encompassed within the invention disclosed and claimed herein.
• While the above detailed description has shown, described, and pointed out novel features of the invention as applied to various embodiments, it will be understood that various omissions, substitutions, and changes in the form and details of the device or process illustrated may be made by those skilled in the art without departing from the invention. The foregoing description is of the best mode presently contemplated of carrying out the invention. This description is in no way meant to be limiting, but rather should be taken as illustrative of the general principles of the invention. The scope of the invention should be determined with reference to the claims.
