US20070079324A1 - Method and apparatus for combining broadcast schedules and content on a digital broadcast-enabled client platform - Google Patents

Abstract

§A service provider broadcast system and method are described. The method includes acquiring network service information regarding broadcast service content to be broadcast by a broadcast service system over a predetermined period. Using the network service information, a composite content list is created, including meta-data describing service provider content available from the service provider system and the broadcast service content. The composite content listed is broadcast to client systems, which in turn, provide ratings for the service provider and broadcast service content described by the composite content list. Using the received ratings, the service provider system selects a portion of the broadcast service content and generates a broadcast schedule for the selected content. The broadcast schedule is then broadcast to the client systems to enable the client systems to store one or more of the content data files from the selected portion of the broadcast service content.

Description

CROSS-REFERENCE TO RELATED APPLICATION
• This application is a continuation of co-pending U.S. patent application Ser. No. 09/854,129, filed May 11, 2001.
FIELD
• The present invention relates generally to broadcast systems. In particular, the present invention relates to a method and apparatus for combining broadcast schedules and content on a digital broadcast-enabled client platform.
BACKGROUND
• Broadcast systems traditionally transmit data in one direction—from a server system to a plurality of client systems. Users of the client systems typically consume the signals received from the server system as they are broadcast. One paradigm in which users are provided with content on demand involves server systems that broadcast the same data continuously and/or at staggered intervals. Thus, if a user desires to consume a particular data file on demand, the user “tunes in” to one of the repeated broadcasts of the data file.
• One example of this paradigm can be illustrated with present day “pay per view” movies that are available from cable or satellite television providers. For instance, cable television providers commonly broadcast the same movies repeatedly on multiple channels at staggered intervals. Users that wish to watch a particular movie, “on demand,” simply tune in to one of the channels on which the desired movie is broadcast prior to a broadcast time of the movie. Unfortunately, these continuous and repeated broadcasts of the same data or programs results in a very inefficient use of broadcast bandwidth. Bandwidth used to broadcast the same data repeatedly on multiple channels could otherwise be used to broadcast different data.
• Another paradigm for providing content on demand in a broadcast system involves a user recording a particular data file and later accessing the data file “on demand. For example, a user can set up his or her video cassette recorder (VCR) to record a desired television program. Later, when the user wishes to watch the television program, “on demand,” the user simply plays the earlier recorded program from his or her VCR. Recently, more advanced digital video recorders have become available, which record television broadcasts on internal hard drives instead of the video cassette tapes used by traditional VCRs. However, use of the digital video recorders is similar to traditional VCRs in that the users are required to explicitly set the criteria used (e.g. date, time) to determine which broadcasts are recorded on the internal hard drives.
• Another limitation with present day broadcast systems is that it is difficult for most users of the client systems to provide feedback to broadcasters with regard to programming. As an example, many of today's television broadcasters rely upon Neilson ratings to determine broadcast programming and/or scheduling. Neilson ratings are generally based upon only a small sampling of a cross-section of the public. Consequently, most television viewers have relatively little or no impact on broadcast schedules and/or content. In fact, the pay-per view movies available are certainly not based on user feedback. Furthermore, the user does not have a choice as to when to view a pay-per view event, and therefore must be available during the event broadcast date and time.
• Therefore, there remains a need to overcome one or more of the limitations in the above-described, existing art.

• System Architecture
• FIG. 1 is an illustration of one embodiment of a conventionalbroadcast service system100, as known to those skilled in the art. Thebroadcast service system100 includes aserver103 configured to broadcastinformation101 to a plurality ofclients105,107 and109.Client105 receives a broadcast fromserver103 through alink115 from abroadcast antenna111. Similarly,client107 receives a broadcast fromserver103 through alink117 andclient109 receives a broadcast fromserver103 through alink119 frombroadcast antenna111. Unfortunately, links115,117 and119 are uni-directional wireless radio frequency (RF) links frombroadcast antenna111. Consequently, thebroadcast service system100 lacks the capability for enabling users of the client systems to provide feedback to broadcasters with regard to programming. Moreover, thebroadcast service system100 broadcasts thesame data101 continuously and/or at staggered intervals. Unfortunately, these continuous and repeated broadcasts of the same data orprograms101 results in a very inefficient use of broadcast bandwidth.
• Referring now toFIG. 2A, a serviceprovider broadcast system150 is depicted. The serviceprovider broadcast system150 is designed to work in conjunction with a standard broadcast system, such as thebroadcast service system100, as depicted inFIG. 1. As will be described in further detail below, the service provider broadcast system enables companies or broadcast systems who want to optimize pay-per view royalties or subscription fees to combine their existing broadcast content with digital broadcast cached content provided by a service provider broadcast system.
• The serviceprovider broadcast system150 is configured to broadcastinformation151 to a plurality ofclients155,157 and159, for example, utilizing bandwidth provided by thebroadcast service system100. As such, the serviceprovider broadcast system150 transmits theinformation151 to thebroadcast server103. Theservice provider information151 along with thebroadcast information101 is then broadcast, viaantenna111, to the plurality ofclients155,157 and159. However, those skilled in the art will appreciate that the broadcast of information, as contemplated by the present invention, includes broadcast via cable, satellite, broadcast antenna or the like, as described in further detail below.Client155 receives a broadcast from thebroadcast server103 through alink165 from abroadcast antenna111. Similarly,client157 receives a broadcast from thebroadcast server103 through alink167 andclient159 receives a broadcast frombroadcast server103 through alink169 frombroadcast antenna111. In this embodiment,links165,167 and169 are uni-direction, wireless radio frequency (RF links) frombroadcast antenna111. The format of such broadcasts is, for example but not limited to, known amplitude modification (AM) or frequency modification (FM) radio signals, television (TV) signals, digital video broadcasts (DVB) signals, or the like, which are broadcast through the atmosphere.
• Thebroadcast server103 is configured to broadcast a plurality of broadcast service content data files101, which may be received byclients155,157 and159. In addition, thebroadcast server103 allocates bandwidth to theservice provider server153 in order to broadcast a plurality of provider content data files151, which are also received byclients155,157 and159. The content data files101/151 may include, for example, any combination of a number of different types of files including for example video, audio, graphics, text, multi-media or the like. For purposes of explanation, many of the examples provided in this disclosure assume that the content data files to be broadcast by the server are audio/video files, such as for example movies with moving images and sound. However, it will be appreciated that the content data files broadcast in accordance with the teachings of the present invention are not limited only to audio/video files.
• As illustrated inFIG. 1, thebroadcast service system100 includes a one-way or uni-directional link between theserver103 andclients105,107 and109. However, the serviceprovider broadcast system150, as depicted inFIG. 2A, includes a “back channel” or communications link between each ofclient155,157 and159 and theservice provider server153. In particular, the serviceprovider broadcast system150 showslinks161,163 and165, which may be used byclients155,157 and159, respectively, to send information back toservice provider server153, such as providing feedback to broadcasters regarding programming. Althoughlinks161,163 and165 are illustrated as direct links betweenclients155,157 and159 andservice provider server153, it is appreciated thatclients155,157 and159 may communicate information to theservice provider server153 through indirect links. Indirect links include, for example, but are not limited to broadcasted wireless signals, network communications or the like.
• FIG. 2B is an illustration of a further embodiment of the serviceprovider broadcast system170 in accordance with the teachings of the present invention. As shown, theservice provider server153 utilizes bandwidth provided by thebroadcast server103 to broadcastinformation151 to a plurality ofclients155,157 and159 through anetwork163. In one embodiment,network163 may be any type of communications network through which a plurality of different devices may communicate such as for example but not limited to the Internet, a wide area network (WAN), a local area network (LAN), an Intranet, an Extranet or the like.
• In the embodiment,client155 receivesinformation101/151 broadcast frombroadcast server103 throughlink165. Similarly,client157 receivesinformation101/151 broadcast frombroadcast server103 throughlink167 andclient159 receivesinformation101/151 broadcast from thebroadcast server153 throughlink169. It is noted thatlinks165,167 and169 are shown as uni-directional links fromnetwork163 toclients155,157 and159, in which a back channel, as depicted inFIG. 2A, may be used to communicate information to theservice provider server153. In another embodiment,links165,167 and169 are bi-directional links, which enableclients155,157 and159 to communication information to theservice provider server153.
• FIG. 3 is a block diagram illustrating one embodiment of amachine201 that may be used for theservice provider server153, orclients153,155 or157 in accordance with the teachings of the present invention. Themachine201 is, for example, a computer or a set top box that includes aprocessor203 coupled to a bus207. Themachine201 includes amemory205, astorage211, adisplay controller209, acommunications interface213, an input/output controller215 and anaudio controller227 are also coupled to bus207.
• In one embodiment,machine201 interfaces to external systems throughcommunications interface213. Communications interface213 may include, for example, a radio transceiver compatible with AM, FM, TV, digital TV, DVB, wireless telephone signals or the like. Communications interface213 may also include, for example, an analog modem, Integrated Services Digital Network (ISDN) modem, cable modem, Digital Subscriber Line (DSL) modem, a T-1 line interface, a T-3 line interface, an optical carrier interface (e.g. OC-3), token ring interface, satellite transmission interface, a wireless interface or other interfaces for coupling a device to other devices.
• Acarrier wave signal223 may be received bycommunications interface213 to communicate withantenna111. In addition, acarrier wave signal225 may be received/transmitted betweencommunications interface213 andnetwork113. Thecarrier wave signal225 may also be used to interfacemachine201 with another computer system, a network hub, router or the like. The carrier wave signals223 and225 are, for example, considered to be machine readable media, which may be transmitted through wires, cables, optical fibers or through the atmosphere, or the like.
• Theprocessor203 may be a conventional microprocessor, such as, for example, but not limited to an Intel x86 or Pentium family microprocessor, a Motorola family microprocessor, or the like.Memory205 may be a machine readable medium such as dynamic random access memory (DRAM) and may include static random access memory (SRAM).Display controller209 controls, in a conventional manner, adisplay219, which may be a cathode ray tube (CRT), a liquid crystal display (LCD), an active matrix display, a television monitor or the like. The input/output device217 coupled to input/output controller215 may be, for example, a keyboard, disk drive, printer, scanner and other input and output devices, including a television remote, mouse, trackball, trackpad, joystick, or the like. In one embodiment,audio controller227 controls in a conventional manneraudio output231, which may include for example audio speakers, headphones, an audio receiver, amplifier or the like. In addition, the audio controller may also control, in a conventional manner,audio input229, which may include for example a microphone or input(s) from an audio or musical device, or the like.
• Thestorage211 may, for example, include machine readable media such as for example but not limited to a magnetic hard disk, a floppy disk, an optical disk, a smart card or another form of storage for data. Alternatively, thestorage211 may include, for example, removable media, read-only media, readable/writable media or the like. Some of the data may, for example, be written by a direct memory access process intomemory205 during execution of software incomputer system201. It is appreciated that software may reside instorage211,memory205 or may be transmitted or received via modem orcommunications interface213. For the purposes of the specification, the term “machine readable medium” shall be taken to include any medium that is capable of storing data, information or encoding a sequence of instructions for execution byprocessor203 to causeprocessor203 to perform the methodologies of the present invention. The term “machine readable medium” shall be taken to include, but is not limited to solid-state memories, optical and magnetic disks, carrier wave signals, and the like.
• Referring now toFIG. 4, one embodiment of a serviceprovider broadcast system300, such as illustrated inFIGS. 2A and 2B, is depicted. In one embodiment, the serviceprovider broadcast system300 is configured to have aservice provider server303 broadcast the provider content data files151 to a plurality ofclients305,307 and309 utilizing bandwidth provided by abroadcast server103. The serviceprovider broadcast system300 utilizesbroadcast service content101 broadcast by a broadcast service system, such as thebroadcast service system100 depicted inFIG. 1, in order to select the provider content data files151 broadcast to theclients305,307 and309.
• As described above, thebroadcast service system100 generally broadcasts the same content continuously and/or at staggered intervals to the system's clients,105,107 and109 (FIG. 1). In one embodiment, the serviceprovider broadcast system300 utilizes network service information, which describes the content thebroadcast service system100 will be broadcast over a predetermined period to generate a composite broadcast schedule or composite content meta-data set. In an alternative embodiment, theclient systems305,307 and309 generate the composite broadcast schedule utilizing the network service information for thebroadcast service system100 and network service information for theservice provider system300, which describes a plurality of service provider content data files available from theservice provider system300. The content meta-data describes the plurality of service provider content data files available from theservice provider system300 as well as the broadcast service content data files101.
• In general, meta-data can be considered as a set of descriptors or attribute values that describe content or data files to be broadcast or potentially broadcast fromservers303 and103. In this embodiment, once the composite content meta-data set is formed, the serviceprovider broadcast system300 broadcasts the composite content meta-data set toclients305,307 and309 and receives feedback from the users of the client system regarding the content data files described by the content meta-data. Using this information, the serviceprovider broadcast system300 ranks the service provider content data files and the broadcast service content data files101. Alternatively, thesystem300 may rank the data files based on box office returns, public opinion polls, movie awards (e.g., the Academy Awards), user requests or the like. Once ranked, thesystem300 selects a portion of the content data files having, for example, a higher ranking.
• The selected portion of the service provider content forms the content provider content data files151 that thesystem300 broadcasts to theclients305,307 and309 via thebroadcast server103. Theclient systems305,307 and309 will then store one or more content data files from the provider content data files151. However, in order to direct theclient system305,307 and309 to store one or more content data files from the selected portions of the broadcast service content, thesystem300 generates a selected broadcast service content schedule. In an alternative embodiment, the client system determines the selected broadcast service content broadcast schedule based on network service information for thebroadcast service system100 and network service information for the content provider content data files151. Procedural methods for performing the teaching of the present invention are now described.
• Operation
• FIG. 5 depicts a flow diagram illustrating the flow of events performed in a server and a client of a serviceprovider broadcast system300, for example, as depicted inFIG. 4, for combining broadcast schedules and content on a digital broadcast-enabled client platform. As known to those skilled in the art, digital broadcast networks (whether satellite, cable or terrestrial) make use of service information (SI) to announce the availability of, and acquisition parameters, for content. Typically, these announcements are consumed by a receiver's electronic program guide (EPG), and are used to present and acquire programming. In this environment, premium content (e.g., “Pay-Per-View”, HBO, etc.) may be scattered across the spectrum presented by the EPG. This problem is exacerbated by the introduction of additional broadcasting services, such as cached content service providers that also deal in the distribution of (possibly overlapping) content that may or may not be directly integrated into a broadcast service network's SI. Therefore, in order to reduce the cognitive load placed on users, cached content service providers can become aware of the broadcast service network service information, preferably in a pre-processed (i.e., pre-EPG state) in order to generate a composite content listing.
• Consequently, atprocess block401, aservice provider server303 acquires network SI regarding broadcast service content to be broadcast by a broadcast service system, for example, as depicted inFIGS. 1 and 4, over a predetermined period of time. Atprocess block403, a composite content list or composite content meta-data set is created. The composite content meta-data set includes meta-data describing service provider content available from theservice provider system300 and the broadcast service content to be broadcast by thebroadcast service system100.
• In one embodiment, the creation of the composite content list requires the exclusion of certain content data files that fall into one or more predetermined categories. In certain embodiments, the predetermined categories may include sports programs and events, television programs, news or other repeating broadcasts. However, the service provider broadcast system may include rating an eventual broadcast of such programs. As such, non-excluded programs are then tagged with additional SI attributes. Presumably, these attributes will include a key that can be cross-referenced with data available to the service provider broadcast system. As such, the keys serve the dual purpose of identifying desirable content while simultaneously facilitating the identification of potentially duplicate content. As part of the creation of the composite content list, all duplicate programs are identified and flagged for future reference. In one embodiment, the predetermined period of time during which network SI for the broadcast service content is acquired is, for example, two weeks.
• As referred to herein, a cached content service provider describes a broadcast system wherein the system selects one or more data files to broadcast to one or more client system based on feedback generated by the client system in response to user access of data files. Once the one or more data files are selected, the data files are broadcast to the one or more client systems, which selectively store the one or more of the data files based on rankings of the data files contained in a content rating table. The data files are stored by the client systems in order to enable viewing at a later date and time by a user. This cached content service is provided by the serviceprovider broadcast system300, as depicted inFIG. 4.
• However, the serviceprovider broadcast system300 can be utilized to broadcast content in conjunction with thebroadcast service system100 as depicted inFIGS. 1 and 4. Consequently, content selected by the serviceprovider broadcast system300, for example, in response to client rankings, is transmitted to one or more client systems using bandwidth provided by thebroadcast service system100. However, in order to best utilize bandwidth provided by thebroadcast service system100, the serviceprovider broadcast system300 generates a composite broadcast schedule or a composite content meta-data set in order to receive rankings for the service provider content data files, as well as the broadcast service content data files101. In an alternative embodiment, theclient systems305,307 and309 generate the composite broadcast schedule utilizing the network service information for thebroadcast service system100 and network service information for theservice provider system300, which describes the plurality of service provider content data files available from theservice provider system300.
• By using the composite content meta-data set, thesystem300 can receive rankings for both the service provider content data files, as well as the broadcast service data files. Using the rankings, thesystem300 can select a portion of the content data files, described by the composite content meta-data set, to form a composite content schedule describing the selected portion of content data files. Alternatively, thesystem300 may rank the data files based on box office returns, public opinion polls, movie awards (e.g., the Academy Awards), user requests or the like. However, the selected portion of content data files may contain duplicate data files. As referred to herein, duplicate data files are date files that are available from theservice provider system300 and that will also be by thebroadcast service system100 will broadcast over the predetermined period of time. Consequently, the serviceprovider broadcast system300 can determine whether to broadcast these duplicate content data files using its own bandwidth or await a future date and time for broadcast of the duplicate content data files by thebroadcast service system100.
• Atprocess block405, theservice provider server303 may broadcast a composite content meta-data broadcast schedule to the one or more clients. In one embodiment, the meta-data broadcast schedule indicates some point in the future when the actual meta-data is going to be broadcast by the server. Alternatively, the client systems may use known ports such as, for example, those used in the DVB, service advertising protocol (SAP) or the like, to listen for upcoming service announcements from the server. Otherwise, program and system information protocol (PSIP) tables are acquired by decoding a stream (identified by a well-known PID) that has been multiplexed into the MPEG-2 transport stream to listen for upcoming service announcements from the server.
• Otherwise, eachclient305,307 and309 can contain a known scheduling service, which accepts requests to wake up, or be activated, at a specific time to receive the information broadcast by the server. This scheduling service enables the client to wake up at a specified time and select a specified service. For example, in one embodiment, this selection process can be accomplished by tuning to a specific frequency, such as for example in an Advanced Television Systems Committee (ATSC) or a DVB transponder or the like. The selection process can be based on a set of data, such as for example multi-cast Internet protocol (IP) addresses, which define a service.
• At process block407 client systems may receive the composite content meta-data broadcast schedule from theservice provider server303. In one embodiment,client systems305,307 and309 capture and process this pre-broadcast information in order to determine when to wake-up and receive content, where to receive the content and which content to receive. Alternatively, when the meta-data broadcast schedule is received by the client, a registered application in the client is notified to receive the meta-data broadcast schedule.
• At process block409 the composite content meta-data may be broadcast from the server to the clients at the time specified in the composite content meta-data broadcast schedule. At process block411, the client may receive the broadcast of content meta-data from the server. At process block413, the client system may then update a content meta-data table and a content rating table. In one embodiment, a meta-data table and a content rating table are updated and maintained internally or locally by each client system. In addition, a user of the client system may optionally classify any one or more of the content data files that are described by the received composite content meta-data. As will be discussed, the content meta-data table and content rating table are updated by the client if there are any user classifications. This is shown inFIG. 5 withprocess block415.
• Atprocess block417, the client then sends the ratings of the content data files to the server. In one embodiment, each client in the broadcast network sends the ratings for all of the content data files that are described by the composite content meta-data broadcast earlier from the server. Alternatively, each client sends all or part of the content rating table maintained on the client system.
• Atprocess block419, the server may receive the ratings of the content data files from the client(s)305,307 and309. Atprocess block421, the server then selects a portion of the content data files from the service provider content and broadcast service content having, for example, the highest ratings as determined by the client systems. Alternatively, thesystem300 may rank the data files based on box office returns, public opinion polls, movie awards (e.g., the Academy Awards), user requests or the like. In one embodiment, the server includes processing to aggregate all of the ratings received from the clients. Consequently, the content data files are sorted according to the aggregated ranking. As a result, the server broadcasts the most appropriate or relevant data files for the customer base or clients.
• In one embodiment, the data files to broadcast, and/or the broadcast schedule are determined dynamically by the server in response to the ratings received from the client(s) in accordance with teachings of the present invention. Therefore, in one embodiment, broadcast schedules can change over time depending on which data files are available from the server and which content or data files are accessed and/or classified by the clients.
• At process block423 the serviceprovider broadcast system300 generates a broadcast schedule for content data files contained within the selected portion of broadcast service content, which will not be broadcast by the serviceprovider broadcast system300 as the provider content data files151. A selected broadcast service content broadcast schedule is then broadcast to the one or more client systems as shown inblock423.Process block425 shows that the client systems then receive the broadcast service broadcast schedule from the server.
• In one embodiment, the clients wake-up to receive the selected broadcast service content broadcast schedule from the server. The broadcast schedule indicates, for example, a future time in which selected content data files will be broadcast by thebroadcast service system100. Atprocess block427, the content data files from the selected portion of the broadcast service content are then broadcast from thebroadcast service system100 to the clients at the time specified in the broadcast schedule.Process block429 shows that the client receives the broadcast of contents data file broadcast from thebroadcast service system100. In one embodiment, process block431 shows that client-side filtering is provided by the client selectively storing content data files according to the content rating table as the content data files are broadcast over the predetermined period. In another embodiment, client-side filtering is provided by the client selectively waking up to selectively receive and store content data files broadcast from the broadcast service system according to the content rating table.
• Process block433 shows that the client then updates the content meta-data table and content rating table if there are any user accesses of the stored data files. As described herein, a user access may include a user interacting with, viewing, watching, listening to, reading, consuming, etc., a data file. For instance, one example of a user accessing a data file may be the user watching a particular movie or listening to a particular song provided by one of the stored data files in client. In one embodiment, a user access will result in the meta-data table and content rating table on the client being updated locally.
• FIG. 6 depicts a more detailed flow chart illustrating the selection of the plurality of provider content data files151 that are broadcast to one or more client systems by the service provider broadcast system, for example, as depicted inFIG. 4. Atprocess block501, theservice provider server303 selects a portion of the service provider content data files and the broadcast service content data files101 having higher rankings based on the rankings received from the one or more client systems (selected provider/broadcast content). However, duplicate content data files within both the selected portion of service provider content and broadcast service content should not be broadcast by both the broadcastservice provider system300 as well as thebroadcast service system100.
• Consequently, atprocess block503, it is determined whether a selected content data file is contained in the selected portion of the broadcast service content. If the selected content data file is contained within the selectively selected portion of broadcast service content, at process block505 it is determined whether the selected data file is also contained within the selected portion of service provider broadcast content. If the selected content data file is not contained within the service provider content, atstep509 the selected content data file is added to a set of overlapping content data files.
• Otherwise, atstep507, it is determined whether the selected content data file should be broadcast using service provider bandwidth. (Broadcast by the service provider broadcast system300). If the selected content data file will be broadcast with the service provider bandwidth, atprocess block511, the selected content data file is added to a set of provider content data files151. Atprocess block513,steps503 through511 are repeated for each content data file within the selected portion of service provider content and broadcast service content. As such,steps503 through513 allow the service provider system to determine whether duplicate or overlapping files should be broadcast using service provider bandwidth or broadcast service system bandwidth (broadcast by the broadcast service system100).
• Atprocess block515, the serviceprovider broadcast server300 broadcasts an optimum/provider broadcast schedule prior to broadcast of the provider data files151. The provider data files151 will each be broadcast to the one or more client systems as a group in order to enable storage of the provider data files151 based, for example, on client system content rating tables. However, the overlapping data files may be broadcast at various times, depending on thebroadcast service system100 broadcast schedule. Accordingly, atprocess block517, theservice provider server303 broadcasts a selected broadcast service content broadcast schedule for the overlapping data files prior to broadcast by thebroadcast service system100. Consequently, utilizing the selected broadcast service content broadcast schedule, the one or more client systems can determine whether to store a data file contained within the overlapping data files, once it is available, based on a stored content rating table. In an alternative embodiment, the client system determines the selected broadcast service content schedule based on network service information for thebroadcast service system100 and network service information for the content provider content data files151.
• Atstep519, theservice provider server303 broadcasts the provider content data files151 to the client systems utilizing service provider bandwidth. For example, in an embodiment of the present invention, the service provider broadcast system utilizes bandwidth provided by thebroadcast service system100 in order to broadcast content data files to the one or more client systems viaantenna111. However, the serviceprovider broadcast system300 may broadcast content data files either via antenna311 or vianetwork313. Atprocess block521, thebroadcast service server103 broadcasts content data files from the overlapping content data files to the one or more client systems. As described above, content data files within the overlapping data files will not be sent as a group. These data files are broadcast at the times scheduled by thebroadcast service system100.
• Utilizing a service provider broadcast system in accordance with the teachings of the present invention content available from thebroadcast service system100 may be combined with cached content provided by the serviceprovider broadcast system300. Consequently, atprocess block523, the serviceprovider broadcast system300 receives compensation for each stored data file accessed by a user. Atprocess block525, it is determined whether the data file accessed by the user was broadcast to the user using service provider broadcast system bandwidth or broadcast service system bandwidth. When service provider bandwidth is used, atprocess block527, the serviceprovider broadcast system300 receives a larger portion of the compensation, while atprocess block529, thebroadcast service system100 receives a smaller compensation portion. Alternatively, when broadcast service system bandwidth is used to broadcast a data file, thebroadcast service system100 receives a larger portion of the compensation atprocess block525, while atprocess block531, the serviceprovider broadcast system300 receives a smaller compensation portion.
• Referring now toFIG. 7,FIG. 7 is a flow diagram illustrating events performed by a client system for selectively storing received content data files. Atprocess block601, it is determined whether a client system received a broadcast schedule for the plurality of provider data files151 selected by the serviceprovider broadcast system300. Atprocess block602, once the broadcast schedule is received, the client system stores the broadcast schedule for the plurality of provider content data files151 (FIG. 8). Atprocess block605, it is determined whether a broadcast schedule for the overlapping content data files was received from theservice provider system300.
• Atprocess block607, the client system stores a selected broadcast service content broadcast schedule for the overlapping content data files (FIG. 9). Atprocess block609, it is determined whether the provider content data files151 are available. Atprocess block611, the client selects one or more content data files from the provider data files151 based on a content rating table (FIG. 10). Generally, the provider content data files selected by theservice provider system300 will include content data files which received an overall popularity rating from the one or more client systems. However, each user of the client system will be different and will generally select a subset of the content data files within the provider content data files151. Once selected, atprocess block613, the client stores the one or more selected content data files for future viewing by a user (FIG. 10).
• Atprocess block621, it is determined whether content data files from the overlapping data files are available. Atprocess block623, it is determined whether a content data file, available from the overlapping data files, is desired by the client system based on the content rating table (FIG. 11). As described above, content data files contained within the overlapping content data files may have various broadcast dates and times. Consequently, the client systems will utilize the broadcast schedules to, for example, activate during the availability date and time of the content data file, assuming the content data file is desired by the client system. Atprocess block625, the client system captures the content data file from the broadcast service broadcast of the broadcast data files101 (FIG. 11). Atprocess block627, the client system stores the content data files for future viewing by a user (FIG. 11).
• Referring now toFIG. 12, themachine201, as depicted inFIG. 3, is illustrated in a set-top box configuration. This partial block diagram of themachine201 depicts thedisplay controller209 and thedisplay219 to illustrate the logical flow of data through an MPEG (Motion Picture Experts Group) pipeline within thedisplay controller209. The illustration depicted inFIG. 12 is provided to demonstrate the capture of selected content data files broadcast by both the serviceprovider broadcast system300 as well as selected content data files broadcast by thebroadcast service system100.
• MPEG-2 defines a standard for coding interlaced images at transmission rates above four million bits per second. As known to those skilled in the art, MPEG-2 is generally used for digital TV broadcast and digital versatile disk. The MPEG-2 standard specifies an MPEG transport stream which is a time division multiplexed set of element streams. Generally, content is received by thedisplay controller209 and is demodulated by thedemodulation block231 to determine the original content transport stream. Once demodulated, the content is demultiplexed bydemultiplex block233 to extract the desired element streams. Next, the element streams area decoded atdecode block235 and displayed viadisplay219.
• Generally, the content is decoded into MPEG-2 to streams and displayed on the display device. In addition, stored content data files contained inblock237 may be viewed by a user by being passed to thedecode block235 and displayed on thedisplay219. Likewise, conditional access (CA) block239 is utilized in order to provide encryption keys for decoding protected content prior to display ondisplay device219, for example, to enable pay-per-view viewing of certain content. Unfortunately, depending on the content capture capabilities provided by the various set-top box of the client's systems, the capture of the selected broadcast content will vary depending on the client set-top boxes201.
• FIG. 13 is a flow diagram illustrating the flow ofevents630 in a client set-top box when capturing selected broadcast content broadcast by thebroadcast service system100. Atprocess block631, client software will siphon MPEG data representing the selected content data file from adecode stage235 of an MPEG content transport stream. Atprocess block633, client software stores the elementary streams and attendant data from the siphoned MPEG data. Atprocess block635, client software encodes the stored content streams and data into, for example, packetized element streams. The encoding will generally include service information and file storage information to enable content play-back. Finally, atprocess block637, the client software stores the packetized element streams into a secondary cache to enable playback by a user of the client system. In an alternative embodiment, the packetized element streams are re-multiplexed into a new MPEG-2 transport stream which is stored in the secondary cache. Consequently, when presenting stored movies to the user, the secondary cache is logically merged with a primary cache to create the illusion of a single unified selection of movies. Upon user selection, the indicated content is retrieved from its specific respective cache and channeled through the platforms MPEG decode pipeline for display viadisplay219.
• FIG. 14 is a flow diagram illustrating the flow ofevents640 performed by client software in order to store selected content data files that are captured utilizing content capture capabilities provided by the client system. The content capture capability includes, for example, PVR functionality. Atprocess block641, content data files are captured using content capture functionality of the client platform. Atprocess block643, client software encodes the captured content data file into a packetized element stream. Atprocess block645, the client software stores the packetized element stream into a secondary cache to enable playback by a user. The encoding procedure described inFIGS. 13 and 14 is required to wrap the resulting or captured streams into a client compatible packaging in order to enable playback of the selected content data files. However, for selected content data files broadcast by the serviceprovider broadcast system300, the content data files will already be encoded into compatible packaging which is recognized by the client software.
• FIG. 15 is a more detailed flow diagram illustrating one embodiment of the flow ofevents650 in a client when processing meta-data broadcasted from a server to update and maintain a meta-data table and a content rating table. In particular, process block653 shows that a content meta-data table is updated with attributes and attribute values included in the content meta-data broadcast from the server.Process block605 shows that the content rating table is then updated with an entry for each one of the content data files described by the content meta-data broadcast from the server.
• To help illustrate the meta-data aspect of the present invention,FIGS. 16-23 illustrate meta-data and content rating tables in accordance with the teachings of the present invention.FIG. 16 is an example of one embodiment of content meta-data700, which may be broadcast by thebroadcast server103 to theclients305,307 and309. For explanation purposes, it is assumed that the data files broadcast by thebroadcast server103 in this example are audio/video files such as, for example, movies or TV programming. As mentioned above, data files may be other types of files such as for example but not limited to audio, graphics, text, multi-media or the like.
• In the illustrated embodiment, meta-data700 inFIG. 16 shows that four movies, or data files, will be broadcast later byserver103. These movies shown in this example are “Action Dude,” “The Funny Show,” “Blast 'Em” and “Hardy Har Har.” Meta-data700 includes attributes and attribute values that describe each one of the movies to be broadcast later byserver103. In the example illustrated, two attributes are provided to describe each movie in meta-data700. The attributes shown inFIG. 16 are “Actor” and “Genre.” It is appreciated that other embodiments of the present invention may include different attributes as well as or attributes values. Referring back to the particular example shown inFIG. 16, “Action Dude” is an “action” movie featuring actor “Joe Smith.” “The Funny Show” is “comedy” movie featuring actress “Jane Doe.” “Blast 'Em” is an “action” movie featuring actor “Jane Doe.” “Hardy Har Har” is a “comedy” movie featuring “Joe Smith.”
• FIG. 17 is an example of one embodiment of meta-data table800, which is updated and maintained locally by eachclient305,307 and309. In the illustrated embodiment, meta-data table800 inFIG. 17 has been populated with the data included in meta-data700, which was broadcasted earlier fromserver103. In one embodiment, meta-data table800 includes a list of attributes, attribute values and corresponding relevance values and believability factors. In particular, meta-data table800 includes attribute values “Joe Smith,” “Jane Doe,” “action,” and “comedy.” At this time, the relevance values and believability factors for attribute values “Joe Smith,” “Jane Doe,” “action,” and “comedy” are all zero inFIG. 17. As will be shown, in one embodiment, the relevance values and believability factors of the present invention will be updated and maintained as the user interacts with the client system.
• In one embodiment, the relevance values in meta-data table800 are indicators as to how relevant the associated attribute and attribute values are for predicting a particular user's behavior. For instance, the relevance value indicates how likely it is for the user to watch a particular movie because of this particular attribute value, within a range of values such as for example from −10 to 10. In one embodiment, the believability factors in meta-data table800 are weighting factors to be applied to specific attribute and attribute value pairs when rating or predicting whether a user will actually access a particular data file having that particular attribute value. In one embodiment, believability factors in meta-data table800 are within a range of values such as for example from −10 to 10.
• FIG. 18 is an example of one embodiment of a content rating table900, which is updated and maintained locally by eachclient305,307 and309. In the illustrated embodiment, content rating table900 inFIG. 18 includes a list of the data files described in meta-data700 as well as any additional data files that are currently stored or cached locally by the client.
• In one embodiment, data files may be stored locally by the client in forexample memory205,storage211 or in a locally accessible network bymachine201 ofFIG. 3. For purposes of this disclosure, data files being stored locally by the client may also be interpreted to include a data file stored “locally” by the client in a known network storage configuration, separate from the server. For purposes of this disclosure, the data file being stored or cached locally by the client is to be interpreted as the data file being stored for later access, retrieval or consumption. In one embodiment, the local cache of the present invention is considered to be a first level cache. Thus, the local cache the present invention is sized accordingly to increase the possibility of a single hit.
• Assuming an audio/video data file, a movie is stored locally by the client. After a user watches the movie, the storage space occupied by the movie is generally considered to be available for storage of another movie to be broadcast sometime later. If a user has not watched a particular movie, the storage space occupied by that movie is generally considered not to be available for storage of another movie. However, if there is no additional storage space available and a higher rated movie is to be broadcast, the lower rated unwatched movie may be replaced by the higher rated movie. In an alternative embodiment, a user of the client may retain selected stored content data files.
• Referring back to the embodiment of content rating table900 shownFIG. 18, each movie also has an associated rating, a rating type indicator, an in cache indicator and a next treatment indicator. In one embodiment, the rating indicates a rating value for the associated data file. The rating value in one embodiment may either be explicitly input by a user or implicitly generated by the client system by processing meta-data associated with that particular data file. For example, a relatively high rating value predicts that the particular data file may be of interest to the user. Conversely, a relatively low rating value predicts that the particular data file is unlikely to be of interest to the user.
• In one embodiment, the in cache indicator indicates whether that particular data file is currently stored or cached locally by the client. In the embodiment illustrated inFIG. 18, the movies “Action Dude,” “The Funny Show” and “Blast 'Em” already exist in the local storage of the client system. Conversely, the movie “Hardy Har Har” has not been stored in the local storage of the client system in the example illustrated inFIG. 18.
• In one embodiment, the next treatment indicator is used to track future actions to be taken for the particular data file. For example, if a movie has already been watched by the user, the next treatment indicator would indicate “replace” to indicate that the storage space occupied by that particular movie is available for storage of another movie. However, if the movie has not yet been watched by the user, the next treatment indicator would indicate “keep.” In addition, if the movie has not been stored locally by the client and if the rating value predicts that this particular movie may be of interest to the user, the next treatment indicator would indicate “capture.” While if the movie has not yet been broadcast by the server and the rating predicts that this movie is unlikely to be of interest to the user, the next treatment indicator would indicate “ignore.”
• Referring again toFIG. 15,decision block657 shows that it is then determined whether there is a user classification of any of the data files. Referring briefly toFIG. 16, a user classifies some of the movies, as described by meta-data700. In particular, the user has expressed interest in the movie “Action Dude” by indicating that he or she wishes to receive that movie. In addition, the user has expressed that he or she does not have any interest in the movie “The Funny Show” by indicating that he or she refuses that movie. However, the user has not provided any information or classification regarding any of the remaining movies.
• Referring back toFIG. 15, if the user has classified any of the data files, process block659 shows that the relevance values of the particular attributes of the classified data files are updated in meta-data table800.Process block661 shows that the ratings of data files having attribute values with relevance values that were adjusted in response to the user classification(s) are also adjusted. For example, referring to meta-data table800 inFIG. 20, the relevance values for attribute values “Joe Smith” and “action” are adjusted to reflect that the user explicitly expressed an interest in “Action Dude.” However, if the user has not classified any data files, process blocks409 and411 are skipped.
• Referring again toFIG. 15, if the user accesses any of the data files, as determined indecision block663, process block665 shows that the relevance values and the believability factors of the particular attributes of the user accessed data files are updated in meta-data table800.Process block417 shows that the ratings of data files having attribute values with relevance values that were adjusted in response to the user access are also adjusted. In one embodiment, each time a user accesses or interacts with particular data file, the believability factor of the attribute values of that film are adjusted or updated. For example,FIG. 21 shows a meta-data table800 that is updated or adjusted in response to the user access of “Action Dude.” In this example, the believability factors of “Joe Smith” and “action” are increased since the relevance values for these attribute values were greater than zero. If the user has not accessed any data files, process blocks415 and417 are skipped.
• FIG. 22 shows content rating table900, which is updated in response to the user access of “Action Dude,” as described in process block667. As mentioned earlier, content rating table900 is also updated as described inprocess block661. As shown in content rating table900 ofFIG. 22, “Action Dude” has a rating value of 1. The rating type of “Action Dude” is “explicit” because the user explicitly classified “Action Dude,” as described above in connection withFIG. 19. The in cache indicator indicates that “Action Dude” is presently locally stored by the client system. The next treatment indicator indicates replace because the user has already watched “Action Dude.”
• As shown in meta-data table800 ofFIG. 23, the relevance values and believability factors are updated for the attribute values of unclassified data files that are accessed. For instance, assume that the user now watches the movie “Blast “Em,” which the user did not classify. Recall fromFIG. 16 that the movie “Blast 'Em” features “Jane Doe” and is an “action” movie. As shown inFIG. 21, the relevance value of “Jane Doe” was less than zero, or −1, prior to the user watching “Blast 'Em.” Nevertheless, the user watched “Blast 'Em,” despite the fact that it featured actress “Jane Doe.” Accordingly, the believability factor of the “Jane Doe” attribute the value is adjusted downward since this particular attribute value now appears less likely or relevant when predicting a user's viewing habits. However, the relevance value and believability factor for the attribute value “action” are adjusted upwards since “action” had a relevance value of greater than zero prior to the user watching “Blast 'Em.” Thus, in this example, the relevance value is adjusted upwards from 1 to 2 and the believability factor is also adjusted upwards from 1 to 2. Therefore, the content rating table800 ofFIG. 23 now predicts that “action” movies are movies that the user is more likely to watch.
• It is appreciated that the user is not required to classify data files explicitly in order for the meta-data table800 and content rating table900 to be updated in accordance with the teachings of the present invention. As a result, the content rating table over time will more accurately predict data files in which the user is interested.
• In one embodiment, the data files in which the user is predicted implicitly to be most interested as well as the data files in which the user explicitly classified an interest will be the data files that are cache locally on the client system. In effect, the movies that the user is most likely to want to watch are automatically stored locally, and therefore available “on demand,” without the user having to explicitly request these movies in advance or explicitly specify criteria used to identify the movies.
Alternate Embodiments
• Several aspects of one implementation of a service provider broadcast system for combining existing broadcast content with cached content have been described. However, various implementations of the service provider broadcast system provide numerous features including, complementing, supplementing, and/or replacing the features described above. Features can be implemented as part of the server or as part of the user's computer system in different implementations. In addition, the foregoing description, for purposes of explanation, used specific nomenclature to provide a thorough understanding of the invention. However, it will be apparent to one skilled in the art that the specific details are not required in order to practice the invention.
• In addition, although an embodiment described herein is directed to a video broadcast, it will be appreciated by those skilled in the art that the teaching of the present invention can be applied to other systems. In fact, systems for broadcasting audio, graphics, text, multi-media files or the like are within the teachings of the present invention, without departing from the scope and spirit of the present invention. The embodiments described above were chosen and described in order to best explain the principles of the invention and its practical applications. These embodiments were chosen to thereby enable others skilled in the art to best utilize the invention and various embodiments with various modifications as are suited to the particular use contemplated.
• It is to be understood that even though numerous characteristics and advantages of various embodiments of the present invention have been set forth in the foregoing description, together with details of the structure and function of various embodiment of the invention, this disclosure is illustrative only. In some cases, certain subassemblies are only described in detail with one such embodiment. Nevertheless, it is recognized and intended that such subassemblies may be used in other embodiments of the invention. Changes may be made in detail, especially matters of structure and management of parts within the principles of the present invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed. For example, the particular element may vary depending on the particular application for the data file format while maintaining substantially the same functionality without departing from the scope and spirit of the present invention.
• The present invention provides many advantages over known techniques. The present invention increases the breadth of offering provided by a service provider system by enabling scenarios such as access to content that the service provider system would not ordinarily have broadcast rights to. This provides the user with access to programming for multiple services, thereby increasing their overall satisfaction with the service. In addition, the present invention reduces the user's cognitive load by providing a single personalized list of selections from the various services residing on the box. The user need only learn one interface to access content and is not required to visit more than one location for essentially the same service. Finally, the system allows for optimization of bandwidth by enabling the service provider to factor content already slated for broadcast (albeit via a different channel) to a client out of its scale. This means that the service provider will not have to pay for rebroadcasting content that would already be sent to a client in a timely fashion, but rather concentrate on providing a unique offering to the consumer.
