| Abstract: | A video conference system based on CATV and IP network is proposed. As a center part, the conference server schedules the transfer of data and control flows. Based on IP network, the data of interactive operations such as conference control and exchange between conference server and conference halls. And the audio and video data of the conferences are uploaded to conference server by IP network. Based on multicast, the uploaded audio and video data are carried by CATV network due to the high-speed and steady downstream bandwidth, |
