This invention relates to Multilocation Video Teleconferencing which can be used with the SKYNET? satellite communication services. The system allows a conference director to teleconference with people in any one of several conference rooms on a dynamic basis. In a multilocation video teleconference, the conference director determines which one of the rooms should be seen by all of the remaining rooms. The network performs dynamic switching to bring the new video signals to all rooms. This switching, occurs very quickly after issue of the commands by the director. The network can use two satellite channels. One channel can be assigned to the broadcasting room and the second channel can be assigned to another auxiliary room under the director's control. The video teleconferencing switching controller receives commands from the director's room and requests from the common conference rooms through video conference controllers located in the conference rooms. The video teleconferencing switching controller sends commands to the local controllers, called Monitor And Remote Controller, at the earth stations in order to execute the director's commands. Each Monitor And Remote Controller translates the commands received from the video teleconferencing switching controller to control the associated satellite modem at the earth station per the director's commands.
