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.

System and method for using a plurality of processors to support a media conference

Internet nodes having global positioning receivers or the like are configured for communicating position information over the Internet, using an Internet protocol (IP). Preferably, information packets according to the protocol include some or all of a source identifier, a time stamp and/or an indicator of the type or format of the position information. Preferably, end-users may provide for encryption, passwords or other features for controlling the entities which can receive or use the position information.

Real-time positioning internet protocol method and apparatus

A system for maintaining a plurality of media conferences includes digital signal processors (DSPs) and a system resource management (SRM) module coupled to the DSPs. Each DSP receives input data packets from conference participants, processes the input data packets to generate output data packets, and communicates the output data packets to the conference participants. The SRM module may migrate a media conference from a first DSP to a second DSP.

System and method for maintaining a plurality of media conferences

A device for supporting a plurality of media conferences includes digital signal processors (DSPs) and a system resource management (SRM) module coupled to the DSPs. Each DSP receives input data packets from conference participants and processes the input data packets to generate output data packets. Each DSP determines whether the media conference is set to an active mode and communicates the output data packets to the conference participants in response to determining that the media conference is set to the active mode. The SRM module allocates a media conference to a first DSP and a second DSP and sets the media conference to the active mode in the first DSP and a stand-by mode in the second DSP. The first DSP communicates output data packets associated with the media conference in response to the SRM module setting the media conference to the active mode in the first DSP. The SRM module sets the media conference to the active mode in the second DSP and de-allocates the media conference from the first DSP, and the second DSP communicates output data packets associated with the media conference in response to the SRM module setting the media conference to the active mode in the second DSP.
