Abstract: In a system that transmits packets containing timestamps and information from a transmission site to a reception site at a transmission bit rate the packets may experience jitter, i.e. variable delay, during transmission. In such a case, the packets are temporally shifted relative to the timestamps and to other packets. Where the timestamp values are inserted into selected packets prior to transmission and that timestamp represent the value of the transmission site clock, the method and apparatus of the present invention substantially removes the jitter and adjusts the timestamp values prior to reception of the packets at the reception site. The present invention achieves this goal by receiving the packets at an intermediate site that has a local clock operates at a nominal frequency substantially equal to the nominal frequency of the transmission site clock and uses that clock as a jitter-free clock to correct the packets.
