In a multi-location television conference system that connects five locations A, B, C, D, and E, when speeches take place at the four locations A, B, C, and D at the same time, at a listening location E, images of all the speaking locations A, B, C, and D are displayed on one screen with four divided screen areas. On the other hand, at the speaking location A, images of the speaking locations B, c, and D and an image of the former speaking location E are displayed on one screen with four divided screen areas. In addition, when images of speaking locations are displayed, locations names thereof are also displayed. Thus, a television conference held at a plurality of locations at a time can be smoothly managed as with a real conventional conference.

Multi-location control apparatus, television conference terminal unit,

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.
