The videoconference server rearranges the video signals, the voice signals, and the material data signals received from the plurality of videoconference terminals. It sends the rearranged signals back to the videoconference terminals via the ATM network. The videoconference administration server controls network connections between the videoconference server and the videoconference terminals.
