Description of drawings
Fig. 1 is the flow chart of the method for video conference provided by the invention;
Fig. 2 is the structure chart of a kind of video conferencing system provided by the invention.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
The invention provides a kind of method of video conference, (multi controlunit MCU) finishes this method, and this method comprises the steps: as shown in Figure 1 by multipoint control unit
S11, after video conference connect to be set up, receive session that the roll-call terminal the sends request of calling the roll;
S12, send this session request of calling the roll to quilt roll-call terminal;
S13, after receiving this session roll-call request responding that is sent by the roll-call terminal, obtain the roll-call terminal and by the video data of roll-call terminal;
S14, broadcasting described roll-call terminal and by the video data of roll-call terminal.
Optionally, realize that the method for S14 can also comprise later: be merged into a voice data with the roll-call terminal with by the voice data of roll-call terminal, the voice data that broadcasting is associated with.
Realize S14 method can for, with described roll-call terminal be broadcast to all terminals of video conference with the form of many pictures by the video data of roll-call terminal.Concrete implementation method can for: be merged into the video data of many pictures with the video data of roll-call terminal with by the video data of roll-call terminal, broadcast the video data of many pictures; Wherein the video data of many pictures can for: with the video data of picture-in-picture form, can certainly be the video data of roll-call terminal for half of display screen, second half is by the video data of roll-call terminal.
Need to prove that the above-mentioned session request of calling the roll can be a new command request that is provided with, can certainly in original request, increase a session identification and realize session roll-call request.In addition, this session request of calling the roll also includes by the sign of roll-call terminal (for example IP address or MAC Address).
Need to prove, the implementation method body of above-mentioned S14 can for: send roll-call terminals and by the video data of roll-call terminal to all terminals of video conference.
The implementation method of certain above-mentioned audio data broadcasting can also for: send voice data after merging to other terminal (except that the roll-call terminal with by all terminals the roll-call terminal) of video conference; Send by the voice data of roll-call terminal to the roll-call terminal, send the voice data of roll-call terminal to quilt roll-call terminal.The method that adopts this kind mode to describe with respect to epimere reduces the transmission of voice data, has the advantage that reduces transmitted data on network, with the roll-call terminal is example, because what sent this moment only is by the voice data of roll-call terminal, do not need to send the voice data of roll-call terminal, so reduced the traffic volume of data, and the voice data that does not send the roll-call terminal can also avoid system's echo (because Network Transmission always has certain time-delay, if play self voice data of (call the roll or by the roll-call terminal), then system's echo may occur).
Need to prove, above-mentioned with the roll-call terminal and by the voice data of roll-call terminal be merged into a voice data method can for: obtain roll-call terminal audio frequency data time and should time corresponding audio data, obtain by time of roll-call terminal audio frequency data and should time corresponding audio data, be merged into a voice data chronologically with roll-call terminal audio frequency data with by roll-call terminal audio frequency data.Certainly the method that merges voice data can also be other method of the prior art, and the present invention does not limit the concrete grammar that merges voice data.
Optionally, said method can also comprise after S14: shield the voice data that other terminal (except the roll-call terminal with by the terminal the roll-call terminal) is sent.
When method provided by the invention is carried out video session at needs, obtain, broadcast the roll-call terminal and, make all conference terminals can both see the video data of roll-call terminal by the video data of roll-call terminal by the video data of roll-call terminal and roll-call terminal.
The specific embodiment of the invention also provides a kind of video conferencing system, this system as shown in Figure 2, comprise: comprise multipoint control unit 21, and a plurality of video conference terminals that are connected with described multipoint control unit (3A, 3B, 3C, 3D, 3E), wherein multipoint control unit comprises:
Receiver module is used for after video conference connects foundation, receives the session roll-call request that the roll-call terminal 3A in a plurality of video conference terminals sends, and this session is called the roll and asked to comprise the sign of stating to some extent by the roll-call terminal;
Sending module is used for asking to this session roll-call that sent by roll-call terminal 3D of a plurality of video conference terminals;
Receiver module also is used to receive this session roll-call request responding that is sent by roll-call terminal 3D,
Acquisition module is used for after receiver module receives this response, obtains roll-call terminal 3A and by the video data of roll-call terminal 3D;
Broadcast module is used to broadcast roll-call terminal 3A and by the video data of roll-call terminal 3D.
Optionally, above-mentioned broadcast module specifically can be used for described roll-call terminal and is broadcast to all terminals of video conference by the video data of roll-call terminal with the form of many pictures.
Video conferencing system provided by the invention is obtained by the video data of roll-call terminal and roll-call terminal, broadcasts the roll-call terminal and by the video data of roll-call terminal, makes all conference terminals can both see the video data of roll-call terminal.。
It should be noted that said system, each included unit is just divided according to function logic, but is not limited to above-mentioned division, as long as can realize function corresponding; In addition, the concrete title of each functional unit also just for the ease of mutual differentiation, is not limited to protection scope of the present invention.
In addition, one of ordinary skill in the art will appreciate that all or part of step that realizes in the foregoing description method is to instruct relevant hardware to finish by program, corresponding program can be stored in a kind of computer-readable recording medium, the above-mentioned storage medium of mentioning can be a read-only memory, disk or CD etc.
In sum, technical scheme provided by the invention has and can make all terminals see the roll-call terminal and by the advantage of roll-call terminal video data.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
