ABSTRACT:
A system for videoconferencing saves travel time and money. To enable participants to see each other continually and simultaneously, and to show documents and objects, equipment is needed, the costs of which vary with the number of locations to be interconnected, and with measures taken for reducing the needed transmission capacity and the outfit of each terminal. As in known videoconference systems, such as studio, or working place systems, the video and audio signals are switched and/or mixed in the inventive system. The necessary equipment, however, is no longer needed at the respective locations, if a central station for videoconferencing is provided which includes this equipment only in a volume actually necessary for the conference. Each of the connected participant locations only comprises terminal units, the same which are needed for a picture telephone system. In addition, both the video and the audio reception can individually be controlled from each location.
