ABSTRACT:
A method of controlling video signals in a multi-participant video conference involves assessing the level of video signal required from each participant to mix the desired broadcast video signals, and using the result of this assessment to dynamically control the video output from the endpoints of the conference participants. The assessment of the required level of video signal preferably utilizes an audio mixing algorithm, such that the video outputs of those participants whose audio signals are currently being discarded in the audio mixing process are switched off at the endpoints, or are transmitted in a lower bandwidth format, thereby reducing the overall bandwidth requirements of the conference and reducing processor resources to mix the broadcast video signals.
