Method and system for multimedia communication control

摘要

A multipoint control unit (MCU) for facilitating communication between a plurality of endpoints. Each endpoint sends a compressed video signal and receives a compressed video signal. The MCU has a plurality of video input modules and a video output module. Each of the video input modules receives a video signal from one of the endpoints and generally decodes the data into a primary data stream and a secondary data stream. The video output module includes a rate control unit and a generalized encoder that receive the primary and secondary data streams for generally encoding to a compressed output stream for transmission to an endpoint.
