Polytopic dot video conference and polytopic dot video conference device

摘要

In a multi-point video conference system, when a user of one multi-point video conference terminal assigns another multi-point video conference terminal as the other side of a privacy communication, other multi-point video conference terminals which are not an object of the privacy communication control an image and voice of the one multi point video conference terminal on the basis of output control signals from the other multi-point video conference terminals which are not the object of the privacy communication. Therefore, it becomes possible to perform a privacy communication with using a usual multi-point control unit to hereby provide a multi-point video conference system having a general utility at low cost.
