The invention has the beneficial effects as follows: based on stream media technology platform, utilizing P2P technological development to depart from tradition p2p VOD system server hardware and the highest constraint of bandwidth requirement, be truly realized i.e. to put and i.e. broadcast, drag and drop are no-delay.It both can support the equipment of tradition instructor in broadcasting's machine, it is adaptable to large-scale live demand；Can go into battle with a light pack again, it is only necessary to carry instructor in broadcasting's machine flexibly equipment light and handy with mobile phone, notebook, moving camera etc., small-sized live recording demand can be met.Comply with the tendency of the day of unification of three nets, enrich the source video sequence of instructor in broadcasting's machine, reduce the threshold of new media industry, allow more people participate in this industry, promote its development and prosperity.
Detailed description of the invention
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
As it can be seen, a kind of new media director system based on full UNICOM framework, comprising: front-end acquisition device, instructor in broadcasting's all-in-one, user source server, microspur cloud source server, microspur cloud mirror image server, microspur cloud load-balanced server；Wherein, described front-end acquisition device is for the video acquisition at instructor in broadcasting scene；The video signal that described instructor in broadcasting's all-in-one gathers for receiving front-end harvester also and sends to next stage microspur cloud source server, and it supports that hardware loading, wireless loading, IP network load；Described user source server is used for storing user profile, detects and adds up online user's number, and information sent in real time to microspur cloud source server；Described microspur cloud source server is for receiving described instructor in broadcasting's all-in-one and the information of user source server transmission, and make analysis judgement, when the online number of user source server gets more and more, and when reaching the threshold value set, microspur cloud source server can carry out dividing potential drop to user automatically, when the threshold value that online number not up to sets, the most do not carry out dividing potential drop；Described microspur cloud mirror image server is for receiving the information that microspur cloud source server sends；Described microspur cloud load-balanced server is for integrating the information that microspur cloud mirror image server sends, and carries out load balancing, then sends video information to each video terminal.
In the present invention, the acquisition mode of described front-end acquisition device includes hardware collection, wireless collection and network collection.The front-end acquisition device of hardware collection includes the full interface of SDI/HD-SDI/3G-SDI/HDMI/DVI/VGA/YpbPr, and the front-end acquisition device of wireless collection includes taking photo by plane unmanned plane or long distance wireless photographic head or broadcast level high definition professional camera.The full interface of SDI/HD-SDI/3G-SDI/HDMI/DVI/VGA/YpbPr supported by described instructor in broadcasting's all-in-one, and supports RTMP/RTSP/MMS/VJVGA/VJTEACHER/HTTPThe network video stream of TS/UDP TS agreement loads, and also supports to connect the wireless terminal device such as mobile phone or PAD by self integrated WIFI.
Preferably, the quantity of described microspur cloud mirror image server is at least two, and is communicatively coupled with microspur cloud source server, microspur cloud load-balanced server the most respectively.The transmission of Intranet mirror-image fashion is used between described microspur cloud source server and microspur cloud mirror image server, the transmission of public network mirror-image fashion is used between microspur cloud source server and user source server, Intranet TCP/UDP mode is used to transmit between described microspur cloud mirror image server and microspur cloud load-balanced server, VJMS/HTTP or HLS mode is used to transmit between described microspur cloud load-balanced server and video terminal, network plug-flow or hardware is used to connect two ways between described front-end acquisition device and instructor in broadcasting's all-in-one, the i.e. video camera hardware by the full interface of SDI/HD-SDI/3G-SDI/HDMI/DVI/VGA/YpbPr, IP video camera passes through cable network, mobile phone or PAD wireless terminal device transmit by the way of wireless network.
Preferably, described video terminal is outdoor large-size screen monitors, computer, mobile phone, one or more in PAD；Described microspur cloud load-balanced server and open air use VJMS/HTTP mode to propagate between large-size screen monitors, computer, use HLS mode to transmit between microspur cloud load-balanced server and mobile phone, PAD.
Use full-mesh framework collection interaction recorded broadcast, mobile recorded broadcast, scene interaction teaching, practice-training teaching, large-scale activity to take photo by plane in the present invention, numerous new medias such as Campus TV Station, wechat video platform are applied to the whole body.Its front-end collection supports that hardware collection, wireless collection and network video stream load.Hardware collection can realize the full interface of SDI/HD-SDI/3G-SDI/HDMI/DVI/VGA/YpbPr；Wireless collection includes that unmanned plane is taken photo by plane, the wireless collection of long distance wireless camera collection (mobile radio terminal such as mobile phone, PAD), broadcast level high definition professional camera etc. is remote, in, closely gather 1080P video and entirely support, the HD video of collection is steady and audible；Network video stream loads can realize RTMP/RTSP/MMS/VJVGA/VJTEACHER/HTTPTS/UDP TS etc. entirely support, it would be preferable to support video load mode near-complete, the most omnipotent.
The present invention uses to receive and adds DYNAMIC DEPLOYMENT(Dynamical Deployment technology) add VOD CACHE(program request caching techniques with receiving), and include supporting CDN structure and load balancing networking strategy, the users such as broadcasting and TV, education, the Internet, enterprises and institutions can be realized and the programs such as activity, meeting, performance are play to the requirement of round, guaranteeing user's the most dilatory program progress during watching, order video is followed one's inclinations and is seen.
The video signal of UAV Video of taking photo by plane, mobile phone and PAD mobile terminal in Fig. 1 can be loaded in microspur source server by the way of wireless image transmission, and hot line video also can take wireless image transmission or wired network mode to be linked in microspur source server.Microspur cloud mirror image server and microspur cloud load-balanced server are to cooperate with microspur source server and carry out intelligence dividing potential drop, load balancing, are the equal of the clustering functionality of a Cloud Server.Under this framework, front end can connect whole video source (hardware loading, wireless loading, IP network load), use end that various terminal (including outdoor large-size screen monitors, mobile phone, PAD, computer) can be used to carry out live watching, when online number gets more and more, the when that user source server bandwidth reaching certain threshold value, microspur source server carries out dividing potential drop and intelligent load balancing automatically, and user source server does not then have any exception.
The ultimate principle of the present invention, principal character and advantage have more than been shown and described.Those of ordinary skill in the art it should be appreciated that above-described embodiment limits the scope of the invention the most in any form, the technical scheme that the mode such as all employing equivalents is obtained, all fall within protection scope of the present invention.
Part that the present invention does not relate to is the most same as the prior art maybe can use prior art to be realized.
