Abstract
A video conference is set up by a video conference system between three or more video terminals. Each video terminal in the video conference sends its video stream to the video conference system. The video conference system in turn sends out the video streams to video terminals to set up a video conference in the traditional manner. A video controller receives an indication of a change in how at least one of the other video terminals is displaying a video stream from one of the video terminals. Based on the indication of change, a change to the bit rate of the video stream is made. This results in the video conference system be able to send reduced bandwidth based on who is viewing the video conference.
