Abstract Apparatus for developing synchronization of an intermediate layer of signal such as the transport or multiplex layer of a multi-layered compressed video signal, includes at the encoding end of the system apparatus for including a time stamp reference, and provision for a differential time stamp which may be updated by the transit times of respective circuits. At the receiving end of the system, a counter is responsive to a controlled receiver clock signal. The time stamps and the differential time stamps are retrieved from the signal and combined to form a corrected time stamp. The differences of successive sampled count values of the receiver counter are compared with the differences of corresponding successive corrected time stamps to provide a signal to control the receiver clock signal.
