Abstract
Techniques are disclosed for controlling the communication of multimedia electronic signals representing audio, video, and/or data. These techniques operate in conjunction with a system including a network, a multimedia server (MMS) connected to the network, and a plurality of endpoint devices connected to the network. The network is comprised of communications links and switches adapted for selectively connecting and disconnecting the communications links. The endpoint devices are adapted for converting multimedia electronic signals into audio, video, and/or data. The MMS is equipped to control the network such that multimedia signals may be exchanged among a plurality of endpoint devices, thereby providing a multimedia conference.
