Abstract
A videoconference system includes a plurality of computers associated with the system to collectively send and receive video data streams. A video encoding program is stored in a memory and is executable by at least a first computer. When executed, the executing computer encodes video data using one or more encoding parameters. A decode information set request monitoring program is stored in a memory and is executable by at least the first computer, causing the first computer to perform the steps of monitoring the network for receipt of a decode information set request message and responding to the received request message by querying the received message for an ID and, if the ID of the received message corresponds to a video data stream generated from the first computer, communicating the corresponding decode information set including the encoding parameters to at least a computer that transmitted the message.
