摘要
A latency control mechanism for a communication system provides a known constant end-to-end delay between an audio source and one or more end node destinations, even in the case where different paths are used to reach the end nodes. A very low jitter time on the end-to-end latency is obtained, and the latency is controllable within a given range in dependence on the constraints imposed by the implementation. A block RX DPLL and latency control unit adjusts the reading moment and position from the RX buffer so that a delay between the time stamp taken at the source side by the transmitter time stamp unit, and the time stamp taken at the receiver side by receiver time stamp unit is constant and equal to a given value.
