A video conferencing network for providing videos, audio, and data communication between remote video terminals. Each of the video terminals transmits and receives video, audio, and data information through the network. The network includes a central switching network for receiving audio and video information on one of a plurality of audio/video ports and selectively interconnecting this information to remaining audio/video ports. A centralized controller is in data communication with each of the video terminals and the switching network and controls the configuration of the switching network to provide the appropriate audio and video paths in response to the data received by the controller from the video terminals.
