A kind of expanded type multihead display system for video conference
Technical field
The utility model relates to a kind of video conference correlation technique, especially relates to a kind of expanded type multihead display system for video conference.
Background technology
Internet video is along with the arrival in global IT application epoch, and the approach that people understand things, exchange message develops into by modes such as the acousto-optic signals of telecommunication from basic paper, pen, books, speech etc., carries out more accurate, faster, expression more galore.Under the promotion of demand, Multimedia Computer Technology combines with the communication technology, develop into a kind of new mechanics of communication--multimedia communication technology gradually, video conference has been brought into play huge channeling as the typical case of Multimedia session type communication service in social information interchange.It can provide directly for the user, comprehensive communication exchange mode, and can save time, reduce cost, boost productivity.
Along with most enterprises and institutions begin to use video conferencing system, increase to later stage branch, the video system capacity increases, the quantity of the many split screens of MCU under existing technology (multipoint control unit) is had too many difficulties to cope with regard to some, is difficult to realize the regular working meeting of large enterprise and trains convention etc.
The utility model content
The purpose of this utility model is exactly the expanded type multihead display system that is used for video conference that provides a kind of favorable expandability for the defective that overcomes above-mentioned prior art existence, reduced cost.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of expanded type multihead display system for video conference, it is characterized in that, comprise control subsystem, general headquarters' video acquisition display subsystem, branch's video conference terminal and communication network, described control subsystem, general headquarters' video acquisition display subsystem, branch's video conference terminal connect by communication network between any two.
Described control subsystem comprises conference management server and multipoint control unit.
Described general headquarters video acquisition display subsystem comprises general headquarters' video conference terminal, image splicer, the big screen display screen that connects successively, and described general headquarters video conference terminal is connected with communication network.
The number of described branch video conference terminal is 1~112.
Compared with prior art, the utlity model has following advantage:
1, can realize network teleconference system split screen quantity expanded type solution with any producer (according to ITU) standard;
2, to original system and in the effective combination of the system that builds, do not waste any resource;
3, reduce the video conferencing system cost of investment;
4, a bit all can realize split screen expanded type display mode arbitrarily.
