Abstract: The present invention provides a video conference system. The video conference system includes a plurality of terminal equipment and a server. Each of the terminal equipment estimates and transmits real-time bandwidth and conference requirements to the server. A multipoint control unit of the server includes a multipoint controller and a multipoint processor. The multipoint controller determines, according to the real-time bandwidth and the conference requirements, a transfer rule and an allocation scheme corresponding to each of the terminal equipment. The multipoint processor receives the transfer rule and voice data stream or video data stream from the terminal equipment. The server transmits each of the allocation schemes to the corresponding terminal equipment. When any of the terminal equipment transmits new real-time bandwidth or new conference requirements to the server, the multipoint controller determines the transfer rule and the allocation schemes once again.
