Abstract
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.
