Abstract
A video conference system enables a video conference to be opened with the exception that a reservation server which accepts the reservation of the conference executes control of conference opening. A user inputs reservation information of the video conference relative to a reservation server while using a personal computer. When the reservation server accepts reservation, the reservation server generates a reservation number. The reservation server transmits the reservation number to any of multi-point control units. The multi-point control unit manages a reserved reservation number. A conference participant inputs the above reservation number on the occasion of circuit connection as a sub-address from any of the video conference terminal devices. The multi-point control unit receives the above reservation number on the occasion of signal reception. The multi-point control unit decides whether or not the reservation number received is the same number that the multi-point control unit manages. If the both numbers agree, it causes the conference to be opened. When another conference participant performs circuit connection with the same reservation number, it causes the conference participant to participate in the video conference which was just opened.
