Abstract： |
The video meeting system includes servers and clients with communication relation being built already. The method includes: building three parallel connections in different divisions of work for communications between servers and clients: one for transferring video data, one for transferring audio data, and another one for transferring control information. When network bandwidth is insufficiency, based on principle of preferential guaranteeing transmission of audio data and reasonable quitting transmission of video data, connections of transferring audio data and transferring video data are adjusted. 'Reasonable quitting' means number of video frame in video data queue is limited. The invention guarantees transmission of audio data effectively in case of network bandwidth is insufficiency. |
