  • System and method for maintaining a plurality of media conferences
    Patent number: 6744741
    Abstract: 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.
    Type: Grant

  • System and method for communicating data among a plurality of digital signal processors
    Patent number: 6650696
    Abstract: A system for communicating data among digital signal processors (DSPs) includes DSPs and a shift register. Each DSP includes a transmit node that communicates data and a receive node that receives data. The shift register includes an input node coupled to the transmit node of each DSP and an output node coupled to the receive node of each DSP. The input node receives data from the transmit node of each DSP, and the output node communicates the data received at the input node to the receive node of each DSP.

  • System and method for supporting a plurality of media conferences
    Patent number: 6606306
    Abstract: 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.
