Media detection and packet distribution in a multipoint conference
First Claim
1. A method, comprising:
- receiving a plurality of audio signals, wherein each of the plurality of audio signals is coded with one or more audiometrics, each of the audiometrics including an acoustic measurement from a conference site of a plurality of conference sites;
receiving a plurality of video signals, each of the plurality of video signals associated with one or more of the plurality of audio signals;
selecting one or more first active audio signals based on one or more of the audiometrics, wherein the one or more first active audio signals comprise a subset of the plurality of audio signals;
selecting one or more first active video signals based on one or more of the audiometrics, wherein the one or more first active video signals comprise a subset of the plurality of video signals;
updating routing information associated with the selected one or more first active audio signals and the selected one or more first active video signals in response to selecting the one or more first active audio signals and the one or more first active video signals, the routing information indicating conference sites to which the selected first active audio signals and the selected first active video signals should be directed; and
distributing the selected one or more first active audio signals and the selected one or more first active video signals in accordance with the routing information.

Abstract
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.
