Media detection and packet distribution in a multipoint conference
First Claim
1. A method for distributing media packets in a multipoint conference, comprising:
- receiving a plurality of audio signals, each of the plurality of audio signals including 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;
extracting one or more audiometrics from one or more audio packets for each of the plurality of audio signals;
selecting one or more active audio signals based on the one or more extracted audiometrics;
determining a change in the active audio signal;
updating a media forwarding table in response to determining a change in an active audio signal, the media forwarding table including a directory for routing one or more of the plurality of audio signals; and
distributing audio packets to one or more conference sites in accordance with the media forwarding table.

Abstract
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.
