Abstract

See full text

A multi-site video conference control system comprising a number of video conference terminals respectively situated at a number of sites and a video conference control unit for controlling a video conference. A communication line interface provided at each terminal makes a single calling with respect to the video conference control unit. A connection data section, which is provided at each terminal, manages connection data for other terminals to be connected and transmits the connection data to the video conference control unit. A control calling section, which is provided at the video conference control unit, calls the terminal corresponding to the connection data to be transmitted from the connection data section, based on the single calling. A connection controller, which is provided at the video conference control unit, connects the calling terminal, whose communication line interface made the single calling, and the other terminals called by the control calling section, with communication lines.
