<p>Disclosed is a transmission system comprising a transmitter, a receiver and a transport network coupling the transmitter and the receiver. The transmitter is provided with time stamp means for generating respective transmission time stamps (TTS) representing a local clock based counting value included in a respective transport data stream (TS). The receiver is provided with a clock generator having a clock frequency control input. The receiver further comprises a time base regenerator coupled to the transport network for calculating a time difference between received successive transmission time stamps. The time base regenerator is coupled to the frequency control input for influencing the clock frequency based on said calculated time difference. This way the reconstruction of an accurate time base is possible, resulting in a more reliable decoding process in the decoder of the receiver and a decreased vulnerability for jitter, such as introduced by an ATM type network.</p> |
