Moderator methods, systems and program products for managing video conferences

摘要

A video conference system in which a plurality of users communicate video to one another over a data network in a video conference and at least one moderator that moderates the video conference. At least one conference server links users and at least one moderator over a data network so users can communicate at least one video data stream to others. A hierarchical arrangement of control parameters control communications between the users over the at least one conference server. Moderator control parameters in the hierarchical arrangement permit the at least one moderator to specify control parameters from the hierarchical arrangement for one or more of the plurality of users and/or participation rights of one or more of the plurality of users. Computer program products provide a moderator with control or participation of users in accordance with a user set of parameters.
