Definitions for "Multipoint Control Unit"
A device that combines audio, video and data streams originating from different endpoints to all other endpoints taking part in the conference. An MCU generally consists of an MC and an MP
A device that bridges together multiple inputs so that more than three parties can participate in a videoconference. The MCU uses fast switching techniques to patch the presenter's or speaker's input to the output ports representing the other participants.
A device to link three or more videoconference locations for fully interactive audio, data and video teleconferencing. An ITU-T compatible MCU must meet the requirements of H.231 and H.243. In addition, the T.12x and T.13x suites of standards, desirable for both codec and MCU, provide greater functionality for multipoint videoconferencing.
