| description | 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. |
