METHOD AND DEVICE FOR CONDUCTING VIDEO CONFERENCES Russian patent published in 2004 - IPC

FIELD: communications engineering.

SUBSTANCE: proposed method designed for conducting multipoint H323 audio/video conferences using TCP/IP protocol in star circuit of broadcast networks to ensure video conference between central device and two terminal devices of broadcast transport network using server of multipoint video conference organization includes transfer of audio/video information from terminal devices and its processing on server, as well as transfer of audio/video data stream from server to terminal devices by means of routers connected to each of them through transceiving channel-forming devices. Filtered off across central router are all audio/video data streams arriving from server, except for first one, with preset address passed to all terminal routers where address is converted so as further on each subscriber codec could acquire given data stream as that assigned to it. This solution makes it possible to transfer data from multichannel video conference organization server to subscriber devices (codices) in broadcast networks with aid of video conference communication equipment using transport protocol TCP/IP and control protocol H323 or SIP.

EFFECT: reduced throughput capacity of data transfer channel between server and codices.
