摘要： A multipoint controller unit in which the audio signal processing is distributed among several audio ports. The control of the audio signal processing may be centrally or distributively managed by one or more audio controllers. The audio signal processing may include selecting audio streams from a common interface and/or mixing the signals from the common interface. Each audio port may enhance the audio signal and generate control information from the audio signal. The audio ports are synchronized by a common information channel while the audio controllers are synchronized by a common control channel interface. Port fragmentation is reduced since the audio signal processing that relates to an endpoint within a conference is handled by a single audio port.

摘要： The present invention is a system and a method for providing a control unit for a multipoint multimedia/audio conference that enables one or more participants to take part in more than one conference simultaneously. The control unit can operate in audio and/or video sections of an MCU and/or Management and Control System (MCS). The MCS, in an exemplary embodiment of the present invention, controls the participation of at least one participant in more than one conference simultaneously by using a Cross-Conference Database (CCDB). The MCU performs connection changes affecting which participants are associated with one or more conferences based on the information that is stored in the CCDB.

摘要： The disclosed method provides audio location perception to an endpoint in a multipoint videoconference by providing a plurality of audio streams to the endpoint, wherein each of the audio streams corresponds to one of the loudspeakers at the endpoint. The audio streams are differentiated so as to emphasize broadcasting of the audio streams through one or more loudspeakers closest to a position of a speaking endpoint in a videoconference layout that is displayed at the endpoint. For example, the audio broadcast at a loudspeaker that is at a far-side of the screen might be attenuated or time delayed compared to audio broadcast at a loudspeaker that is located at a near-side of the display. The disclosure also provides a multipoint control unit (MCU) that processes audio signals from two or more endpoints according to the positions in a layout of the endpoints and then transmits processed audio streams to the endpoints in a way that allows endpoints to broadcast spatially correlated audio.

摘要： A system and method particularly useful in handling the video of a “large” conference is disclosed. The system and method initially defines certain conferees as panel members, which can provide input video signals to the multipoint control unit and can receive output video signals or a composite layout for the conference from the multipoint control unit. The system and method also initially defines audience members, which only passively receive the output video signals or layout from the multipoint control unit and do not have their video signals incorporated into the layout of the videoconference. In one aspect, an audience terminal can request to participate in the conference. By making an appropriate request, the audience terminal can, if system resources are adequate, participate fully as a panel member and may supply video signals to the conference for at least some portion of time. Alternatively, the audience member can supply information other than video signals to the conference, such as voting data or other data allowing the audience member to participate in the conference as more than a merely passive viewing participant.
