摘要： A method for executing a video conference is provided that includes receiving one or more audio streams associated with a video conference from one or more end points and determining an active speaker associated with one of the end points. Audio information associated with the active speaker may be received at one or more media switches. One or more video streams may be suppressed except for a selected video stream associated with the active speaker, the selected video stream propagating to one or more of the media switches during the video conference. The selected video stream may be replicated such that it may be communicated to one or more of the end points associated with a selected one of the media switches.

摘要： 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.

摘要： A method and an apparatus for providing layout selection, participant selection, and/or participant-to-participant far end camera control of the selected participant for use in a continuous presence multipoint videoconference. The method includes receiving an FECC message of a set of FECC messages over a packet network from a first participant, the first participant having a set of FEEC modes and being in one of the FECC modes. The method further includes maintaining knowledge of the mode of the first participant and interpreting the received FECC message according to the FECC mode of the first participant. Depending on the FECC mode of the first participant, the interpreted FECC message, and the set of controls provided by the method (layout selection and/or participant selection to select a participant and/or participant-to-participant camera control), the method further includes one of changing the FECC mode of the first participant, forming a layout for the first participant, selecting a participant for the first participant, or carrying out participant-to-participant camera control of a previously selected participant.
