VIDEOCONFERENCE SYSTEM

摘要

The invention concerns a conference system of the type comprising a bridge (10) whereto a plurality of terminals (1 to 4) can be connected to participate in a conference, said bridge (10) being designed to receive the audio and/or video data flows from each terminal (1 to 4) and forward them to the terminals. The invention is characterized in that the flows emitted by said terminals (1 to 4) are coded with hierarchical encoding means and said bridge (10) is provided with means (21 to 24, 210 to 243) for processing the audio/video/data flows coming from the terminals (j) so that they have a hierarchical level (q) in the flow addressed to the terminal (i) and means (20) for determining said hierarchical level (q) on the basis of decisional criteria associated with said conference system.
