    Abstract: A system for using a plurality of processors to support a media conference includes a mixing processor and a first media transformation processor coupled to the mixing processor. The mixing processor mixes input media information associated with two or more first participants to generate output media information for communication to a second participant. The first media transformation processor receives the output media information from the mixing processor, encodes the output media information to generate an output data stream, and communicates the output data stream to the second participant's end-user device.
