Abstract
A method by which video compression parameters of different video streams are changed to optimize overall bandwidth utilization according to rules related to the varying interactions among group members. Different video streams are allocated different portions of the overall bandwidth based on a priority scheme. The priority scheme is based upon group dynamics. A controller (central or distributed) receives a group dynamics monitoring signal which monitors the various activities of group members. The controller (central or distributed) uses the network congestion control feedback signal and the priorities assigned to the different video streams to send feedback signals to the different video transmitters requesting the transmitters to adhere to, increase, or decrease their video data rates by changing parameters controlling the video encoding process.
