Description
Technical field
The present invention relates to the video stream media application, especially relate to the method for video information transmission in a kind of video living broadcast programs.
Background technology
At present, the information in video living broadcast programs is all unidirectional issue, namely can only be released news to recipient user by content publisher such as TV station, and recipient user can not feedback information; In some cases, some programs of TV station need to exchange with the user, usual way is on broadcast data server, the content program of broadcasting to be carried out superposition, to hang the form adding advertisements information of angle advertisement, the user can reach background server by modes such as phone, notes with feedback information.Under this pattern, the issue of TV information and the feedback of user profile are completed based on heterogeneous networks, and shared resource is more, and such information can only carry out single, really do not reach interaction.Even in can carrying out the Internet of switch type communication, the live video programme information is also one-way transmission, spectators can only be with computer or the unidirectional watching video programme televised live of mobile phone, if want the host's exchange of information with programme televised live, or will be by other communication modes, to the interchange both sides of information, very inconvenient equally, also take too much extra resource, the Communicator will pay extra cost.At present 3G license granting is in sight, and mobile video will be faced with opportunity to develop, increasing cellphone subscriber can be by mobile phone live or some video frequency programs of program request appreciate or carry out video study, this is the traditional mode of watching program of very large change also.And at present mobile phone watch program also not truly reach a kind of interaction, also can't with other spectators and program in the welcome guest mutually exchange.
Summary of the invention
The objective of the invention is to increase the degree of participation of spectators when the watching video programme televised live, promote the interactive of video frequency program, propose the method for video information transmission in a kind of video living broadcast programs, the method comprises the steps:
1) video server sends live video information to client, plays after client player receiver, video information;
2) customer end A sends to direct broadcast server and opens the in place interaction request of video, and after direct broadcast server was accepted this request, customer end A starts local video shot with video-corder, and this audiovisual information of shooting with video-corder is in real time sent to direct broadcast server;
3) direct broadcast server real-time audiovisual information that customer end A is sent is processed, and the audio conversion of looking in real time of customer end A is issued other and watched live customer end B;
4) another additional window occurs in the main window of the player of customer end B, in this additional window, client end of playing back A's looks audio frequency in real time.
In above-mentioned living broadcast interactive, customer end B can maximize the additional window of looking in real time audio frequency of client end of playing back A or minimize, or regulates its big or small also moving window position.Customer end B can be closed the additional window of looking in real time audio frequency of client end of playing back A, and this moment, direct broadcast server no longer sent the real-time audiovisual information of customer end A.
When the additional window of looking in real time audio frequency of the main window of the player of customer end B and client end of playing back A has video content to play simultaneously, the situation that the audio frequency phase mutual interference of 2 windows will occur, solution is: can select to close the audio frequency output of a window by player, or export simultaneously two audio frequency in window by left and right acoustic channels.
In above-mentioned living broadcast interactive, the quantity of customer end A can be more than 2 or 2, direct broadcast server can select the real-time audiovisual information of the customer end A more than 1 or 1 wherein to forward, customer end A can select the audio frequency of looking in real time of any one or a plurality of customer end A to play, and can change at any time or close the audio frequency of looking in real time of any one or a plurality of customer end A and play in playing process.Client can freely be selected the multichannel interdynamic video like this.
In live process, the real-time audiovisual information that direct broadcast server can be closed any one or a plurality of customer end A at any time forwards, corresponding broadcast window autoshutdown on customer end B when closing.Direct broadcast server can be controlled the interactive live video from client like this.
Further improvement in the technical proposal is: direct broadcast server can show below information in real time: the total quantity of connected client; The total quantity of the live customer end A of connected interaction; The quantity of other client that each interactive live customer end A connects.These information can show in the specialized information window of player, and the user can therefrom select the live customer end A of any interaction to watch its interdynamic video.
The above-mentioned customer end A of carrying out interactive live video comprises following several situation:
Living streaming server sends video program data by the Internet to customer end B, and correspondingly, described customer end B is the computer of accessing Internet.
Living streaming server sends video program data by mobile communication network to customer end B, and correspondingly, described customer end B is the mobile phone of access mobile communication network.The mobile communication network here can divide following two kinds:
◆ mobile communication network is GPRS network, and correspondingly, described customer end B is for supporting and open the gsm mobile telephone of GPRS network.
◆ mobile communication network is cdma network, and correspondingly, described customer end B is for supporting and open the CDMA mobile phone of cdma wireless online.
The present invention can bring following beneficial effect:
Use technical scheme of the present invention, spectators can participate in the live video program of its appreciation, carry out video interactive with the host of current programme televised live, and send the scene of video interactive to other spectators and share, the obvious like this interest of appreciating video frequency program that promoted, especially in video frequency program, some has the value of discussion topic, more can cause spectators' participation enthusiasm, improve the audience ratings of video frequency program, remote online training as net cast, after teacher putd question to, the student can answer, and the process of teachers and students' question and answer shows in live.
