System and method for video conferencing
First Claim
1. A method for video conferencing comprising:
- receiving a request to subscribe to a voice activated (VA) multicast group from one or more VA endpoints;
receiving a request to subscribe to a continuous presence (CP) multicast group from one or more CP endpoints;
multicasting a current speaker'"'"'s stream to the VA endpoints that are not the current speaker; and
multicasting a continuous presence, current speaker stream to the CP endpoints that are not the current speaker, wherein the continuous presence, current speaker video stream comprises two or more video streams, one of which includes at least a portion of the current speaker'"'"'s video stream.

Abstract
In one embodiment, an apparatus includes two modules. A first module receives a request from a first endpoint to subscribe to a voice activated multicast group and causes the first endpoint to receive a current speaker'"'"'s video stream if the first endpoint is not the current speaker and to receive a last speaker'"'"'s video stream if the first endpoint is the current speaker. A second module receives a request from a second endpoint to subscribe to a continuous presence multicast group and causes the second endpoint to receive a continuous presence, current speaker video stream if the second endpoint is not the current speaker and to receive a continuous presence, last speaker video stream if the second endpoint is the current speaker. The continuous presence, current speaker video stream includes a composition or two or more video streams, one of which includes at least a portion of the current speaker'"'"'s video stream. The continuous presence, last speaker video stream includes a composition or two or more video streams, one of which includes at least a portion of a last speaker'"'"'s video stream.
