Description

Method of video information transmission in a kind of video living broadcast programs

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 all is unidirectional issue, promptly 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 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 then 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 finished based on heterogeneous networks, and shared resource is more, and such information can only carry out single, really do not reach interaction.Even can carry out in the Internet of switch type message transmission, the live video programme information also is an one-way transmission, spectators can only be with computer or the unidirectional video living broadcast programs of watching of mobile phone, if want host's exchange of information with programme televised live, still will be by other communication modes, to the interchange both sides of information, equally very inconvenient, also take too much extra resource, the Communicator will pay extra cost.3G license granting at present 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, the traditional mode of watching program of this also very big change.And mobile phone watches that program does not have a kind of interaction that reaches truly yet, also can't exchange mutually with the welcome guest in other spectators and the program at present.

Summary of the invention

The objective of the invention is to increase the degree of participation of spectators when watching video living broadcast programs, promote the interactive of video frequency program, propose the method for video information transmission in a kind of video living broadcast programs, this method comprises the steps:

1) video server sends live video information to client, plays after the client player receiver, video information;

2) customer end A sends to direct broadcast server and opens the request of video in place interaction, 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 is handled the real-time audiovisual information that client Λ sends, and the audio frequency of looking in real time of customer end A is transmitted to other and watches live customer end B;

4) another additional window occurs in the main window of the player of customer end B, client end of playing back A's looks audio frequency in real time in this additional window.

In above-mentioned living broadcast interactive, customer end B can maximize the additional window of looking audio frequency in real time of client end of playing back A or minimize, or regulates its size and moving window position.Customer end B can be closed the additional window of looking audio frequency in real time 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 audio frequency in real time 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: export by the audio frequency that player can select to cut out a window, or export two audio frequency in the window simultaneously 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 transmit, what customer end A can be selected any one or a plurality of client Λ looks voice playing in real time, and that can change or close any one or a plurality of customer end A at any time in playing process looks voice playing in real time.Client can freely be selected the multichannel interdynamic video like this.

In live process, direct broadcast server can be closed the real-time audiovisual information of any one or a plurality of customer end A at any time and be transmitted, when closing on the customer end B corresponding broadcast window close automatically.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 that the user can therefrom select the live customer end A of any interaction to watch its interdynamic video.

The above-mentioned client Λ that carries out interactive live video comprises following several situation:

The net cast server sends video program data by the Internet to customer end B, and correspondingly, described customer end B is for inserting the computer of the Internet.

The net cast server sends video program data by mobile communication network to customer end B, and correspondingly, described customer end B is for inserting the mobile phone of mobile communication network.The mobile communication network here can divide following two kinds:

◆ mobile communication network is a GPRS network, and correspondingly, described customer end B is for supporting

And open the gsm mobile telephone of GPRS network.

◆ mobile communication network is a 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 some has the value of discussion topic in the video frequency program, 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.
