Abstract
A rate adaptive video conference bridge and related techniques are provided. At a video conference bridge, a source video stream is received from a source endpoint device in a network. The source video stream is encoded using a first encoder unit and second encoder unit to generate respective first and second encoded video streams. A determination is made whether to decrease or increase a bit rate of the source video stream based on network condition information. If the bit rate is to be decreased, the first encoder unit is instructed to send the first encoded video stream to a destination endpoint device. If the bit rate is to be increased, the second encoder unit is instructed to send the second encoded video stream to the destination endpoint device.
