Multipoint conference video switching
First Claim
1. A method comprising:
- receiving a plurality of audio signals at a conference site, wherein;
the audio signals comprise a plurality of packets containing voice data associated with a plurality of conference participants at the conference site; and
one or more of the audio signals is associated with a video signal;
determining an activity metric at the conference site for each of the plurality of audio signals, wherein the activity metric indicates a confidence value that the audio signal is associated with a conference participant that is currently talking;
encoding, for each of the plurality of audio signals, one or more packets of the plurality of packets with the activity metric; and
sending the plurality of audio signals encoded with an activity metric to a conference bridge.

Abstract
A method includes receiving a plurality of audio signals, wherein the audio signals each include a plurality of packets containing voice data associated with conference participants. One or more of the audio signals is associated with a video signal and at least one of the audio signals is associated with a voice-only conference participant. The method further includes determining an activity metric for each of the plurality of audio signals, wherein the activity metric indicates a confidence value that the audio signal is associated with a conference participant that is currently speaking. The method also includes encoding, for each of the plurality of audio signals, one or more packets of the plurality of packets with the activity metric and sending the plurality of audio signals encoded with an activity metric to a conference bridge.
