Description
Technical field
The present invention relates to communication technique field, more particularly, relate to a kind of video communication bridge system and method.
Background technology
Along with rapid development of economy, the Internet becomes the leading of the world gradually, and in the time, it is more and more perfect that network becomes at short many decades.Networks development has also promoted the variation of mechanics of communication, and traditional exchange way can not satisfy the growing demand of people.Video communications system real-time Transmission video and audio-frequency information make both sides can carry out real audio frequency and video directly perceived at a distance and exchange.Utilize the support of multimedia technology, video communications system can better give expression to the idea of oneself, can more effectively link up.
The video communications system of main flow has two types in the market.One type is based on standard agreement, such as the video communications system of H323/SIP, is mainly used in private network network environments such as government, bank; Be characterized in good at private network environment middle pitch video quality; Be simple and easy to usefulness, its shortcoming is the network environment of incompatibility the Internet fluctuation, and price is also relatively more expensive in addition.The another kind of video communications system that is based on proprietary protocol is mainly used in the internet communication environment, and its advantage is that network-adaptive property is strong, and function is abundanter and flexible, low price, and its shortcoming is that mutual said audio frequency and video fluidity is poor.
Under the situation of a lot of reality; Such as large and medium-sized enterprise or province, department of municipal government; Have private network circuit environment, adopted expensive H323/SIP video communications system, and to three, level Four administrative department; Possibly have only internet environment, the client need a kind ofly can satisfy the video communication product that can adapt to internet environment with original H323/SIP system docking, again.How realizing the bridge joint of this two type systematic, is the problem of at present a lot of manufacturers headache, although some manufacturer has also proposed some solutions, realizes that effect is not very desirable.
Existing bridge joint implementation mainly contains two kinds:
1, adopts the back-to-back mode of hardware.See also Fig. 1, be hardware formula video communication bridge joint sketch map back-to-back.As shown in Figure 1; In same meeting-place, set up two dissimilar terminals, a video communication terminal that is based on proprietary protocol; Such as ANYV video communication terminal; Another is based on the video communication terminal of standard agreement, such as H323/SIP video communication terminal, and the input and output each other of the audio frequency and video of two equipment.
2, adopt the software package mode.See also Fig. 2, be software package formula video communication bridge joint sketch map.As shown in Figure 2; At video communication terminal based on proprietary protocol; Such as articulating the support standard agreement on the ANYV video communication terminal; Such as the plug-in unit (DLL or OCX) of H323/SIP agreement, the conversion that the video communication terminal inner is done signaling and Media Stream (ANYV stream and rtp streaming) realizes the video bridging functionality at xenogenesis communications protocol terminal.
Yet there is following shortcoming in existing technical scheme at present:
1, adopts the back-to-back mode of hardware.Need two locking terminals, the extra increase system cost of one side meeting, the bridge joint setting up procedure need be operated two equipment simultaneously on the other hand, and is very inconvenient.
2, adopt the software package mode.The signalling interactive process of realizing bridge joint on the one hand is complicated, is one the tunnel because H323/SIP connects the audio frequency and video input and output rtp streaming of supporting on the other hand, can't realize the bridge joint of multichannel audio-video frequency stream.
Summary of the invention
