Abstract
A real time audio multi-point videoconferencing system comprising at least two videoconferencing endpoints in communication with a multipoint control unit, and a method of providing the real time audio. The method comprising capturing input lossless digital audio streams on each of the at least two videoconferencing endpoints, transmitting the input lossless digital audio streams from each of the at least two videoconferencing endpoints to the MCU using a frame size in the range 0.25 ms-3 ms, mixing, using the MCU, the input lossless digital audio streams into a plurality of output lossless digital audio streams, transmitting a different one of the plurality of output lossless digital audio streams to each of the at least two videoconferencing endpoints using a frame size in the range 0.25 ms-3 ms, and playback the plurality of output lossless digital audio streams on each of the at least two videoconferencing endpoints.
