Abstract
In a multipoint control unit for conferencing audiovisual terminals, conference participants are greeted with audio and video welcome messages and then placed in an automated queue. The automated queue is a holding queue from which a conference operator can select the next available conference participant in the queue and conduct a subconference. Apparatus in the multipoint control unit includes a memory for storing video data and a processor coupled to the memory for controlling playback of the video data to a connected terminal during conference setup.
