<p>PURPOSE:To efficiently operate a circuit and to curtail the circuit royalty by providing a function for processing video information, voice information and facsimile information, etc., received from other station by a video conference device of the own station, and also, transferring each received information to a third station. CONSTITUTION:The system is constituted of a transmission control part 10 in an A spot, a video conference device 13 in the A spot, a transmission control part 11 in a B spot, a video conference device 14 in the B spot, a transmission control part 12 in a C spot, a video conference device 15 in the C spot and transmission lines 1, 2, 3 and 4 for connecting each spot, etc. That is, for the purpose of a video conference in the B spot, signals are reproduced by each device, and also, these video information and voice information or facsimile information return to the transmission control part 11 in the B spot through a path 7, pass through the transmission line 2 and reach the C spot. In such a way, in the case of executing a video conference between plural spots, it will suffice that even a station of a terminal bears the circuit royalty only to the relaying spot, and the royalty can be curtailed remarkably.</p> |
