PURPOSE:To realize the efficient multi-point image communication system utilizing effectively a communication channel in which only useful data to be sent are always efficiently relayed. CONSTITUTION:Only storage data by two terminal equipments are sent onto a line tying the terminal equipments. This embodiment is explained about a video conference terminal equipment A301. Video conference terminal equipments D304, E305 receive stored information and send stored information by a video conference terminal equipment E304 and the information produced by their own terminal equipments to a video conference terminal equipment B302 on a clockwise transmission line. On the other hand, video conference terminal equipments B302, C303 receive stored information and send stored information by a video conference terminal equipment B302 and the information generated by their own terminal equipments to a video conference terminal equipment E305 on a counter clockwise transmission line. Since each terminal equipment executes similar relay transmission depending on a terminal equipment storing received information, the information generated in all video conference terminal equipments (A-E) is sent to all the video conference terminal equipments. |
