A plurality of multipoint conference units (MCUs) may optimize bandwidth by selecting particular video streams to transmit to endpoints and/or other MCUs participating in a video conference. An endpoint may generate video streams and audio streams and transmit these streams to its managing MCU. During the video conference, an endpoint may also receive and display different video streams and different audio streams. In a particular embodiment, a controlled MCU receives video streams from its managed endpoints, selects potential video streams based upon the maximum number of video streams that any endpoint can display concurrently, and transmits those potential video streams to a master MCU. The master MCU may also receive video streams from its managed endpoints and may select active video streams for transmission to its managed endpoints and to the controlled MCU, which transmits selected streams to its managed endpoints. |
