Abstract
In a multilocation conference terminal for transmitting audio and video information to a plurality of remote locations, rapid video and non-disrupted audio switching are obtained by employing a plurality of single composite digital signals each including all the video information from an associated location and all of the audio mixes for all of the locations in a conference. Then, the composite signals are switched prior to conversion for transmission to one or more of the locations. Since each composite signal includes all the audio mixes for all of the locations, when video from anyone of the locations is selected for transmission to any of the locations, the audio mixes for those locations are also switched.
