<P>PROBLEM TO BE SOLVED: To provide a video conference system, a band control method, a conference control device, a video conference terminal device and a program, wherein quality of communication can be maintained by preventing an unnecessary bandwidth from being controlled when a use band is varied. <P>SOLUTION: A conference control device is connected with a plurality of video conference terminal devices through a network and controls communication with the video conference terminal devices. The conference control device includes: a communication processing unit which performs transmission and reception processing of conference information containing voice information and image information between the conference control device and the video conference terminal devices through the network; an information collecting unit which collects information on connection paths between the conference control device and the respective video conference terminal devices; a grouping unit which sorts the plurality of video conference terminal devices into a plurality of groups based on information on the connection paths collected by the information collecting unit; a band monitoring unit which monitors the use band of the communication processing unit in the group unit; and a bandwidth control unit which controls, when the group having the use band of less than a predetermined value is detected by the band monitoring unit, the bandwidth of the video conference terminal devices belonging to the group. <P>COPYRIGHT: (C)2010,JPO&INPIT |
