A method includes receiving a plurality of audio signals. Each of the plurality of audio signals includes audio packets, wherein one or more audio packets from each of the plurality of audio signals is coded with an audiometric, the audiometric including an acoustic measurement from a conference site. The method further includes, for each of the plurality of audio signals, extracting an audiometric from one or more audio packets and selecting an active audio signal based on the extracted audiometrics. In addition, the method includes determining a change in the active audio signal and in response to determining a change in the active audio signal, updating a media forwarding table, the media forwarding table including a directory for routing one or more of the plurality of audio signals. The method further includes distributing audio packets to one or more conference sites in accordance with the media forwarding table.

Media detection and packet distribution in a multipoint conference

A method for assigning video signals includes receiving a plurality of video signals from a plurality of cameras located at one or more remote sites, the plurality of video signals for display on a plurality of monitors at a local site. The method includes determining an optimal monitor for displaying a first video signal associated with a first camera based on the location and alignment of the first camera in relation to one or more of the plurality of cameras. The method includes calculating a respective difference between a number of video signals assigned to the optimal monitor and a respective number of video signals assigned to each respective monitor of the plurality of monitors. The method further includes assigning the first video signal to the optimal monitor if the respective difference is not greater than a threshold value with respect to each of the plurality of monitors.

Method and system for optimal balance and spatial consistency

A method for distributing media packets in a multipoint conference includes receiving a plurality of audio signals. Each of the plurality of audio signals includes audio packets, wherein one or more audio packets from each of the plurality of audio signals is coded with an audiometric, the audiometric including an acoustic measurement from a conference site. The method further includes, for each of the plurality of audio signals, extracting an audiometric from one or more audio packets and selecting an active audio signal based on the extracted audiometrics. In addition, the method includes determining a change in the active audio signal and in response to determining a change in the active audio signal, updating a media forwarding table, the media forwarding table including a directory for routing one or more of the plurality of audio signals. The method further includes distributing audio packets to one or more conference sites in accordance with the media forwarding table.

A method for assigning video signals includes receiving a plurality of video signals from a plurality of cameras located at one or more remote sites, the plurality of video signals for display on a plurality of monitors at a local site. The method also includes determining an optimal monitor for displaying a first video signal associated with a first camera based on the location and alignment of the first camera in relation to one or more of the plurality of cameras. In addition, the method includes calculating a respective difference between a number of video signals assigned to the optimal monitor and a respective number of video signals assigned to each respective monitor of the plurality of monitors. The method further includes assigning the first video signal to the optimal monitor if the respective difference is not greater than a threshold value with respect to each of the plurality of monitors.
