ABSTRACT:
Nodes of a computer-based teleconferencing network may be able to encode and decode video signals using different video compression/decompression algorithms with different parameters. In order to conduct a video teleconference between two (or more) such nodes, the nodes must first agree on what video algorithms to use. In the present invention, video capabilities are negotiated between nodes, where each node uses a table that identify one or more sets of video capabilities for that node. After video capabilities have been successfully negotiated, the video conferencing can proceed using the negotiated capabilities. Negotiated video capabilities may include algorithms, frame rate, frame resolution, bit rate, and bitstream format.
