VIDEO ENCODER AND METHOD OF SYNCHRONIZING TIMING FROM ENCODER TO DECODER

摘要

PROBLEM TO BE SOLVED: To achieve multiplexing and synchronize transport packetizing devices.

SOLUTION: An 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 a counter 23 which is responsive to a system clock 22, and the count value is embedded in the signal at the transport layer according to a prescribed schedule. At the receiving end of the system, an inverse transport processing device 18 supplies a PCR and a control signal from auxiliary transport data to a system clock generator 27. The clock generator 27 is responsive to these signals and a system clock signal synchronized to operation of at least the inverse transport processing device 18 is generated. This system clock signal is supplied to a receiver system control device 26 in order to control a timing of processing elements.
