Abstract
A videoconference system includes a camera at each several user locations, a computer at each user location linked to the camera at each location, and one or more bridges linking the computers to one another. A video encoding program stored on each computer causes each computer to encode video data received from the camera at the user location. A decode information set request monitoring program stored on at least one of the computers causes the computer to monitor the bridges for reception of a decode information set request message; and respond to the decode information set request message by querying the request message for an ID. If the ID of the request message matches an ID assigned to the computer, the computer generates a decode information set based on video data received from the camera, and communicates the decode information set to all of the other computers.
