<P>PROBLEM TO BE SOLVED: To develop synchronization of a multiplexing and transport packetizing apparatus. <P>SOLUTION: An apparatus for developing synchronization of a signal of an intermediate layer, such as the transport or multiplex layer of a multi-layered compressed video signal, includes, at the encoding end of a system, a counter 23 that is responsive to a system clock 22, and the counted value is embedded in the signal at the transport layer according to a predetermined schedule by a processor 13. At the receiving end of the system, an inverse transport processor 18 supplies to a system clock generator 27 a PCR and control signals from auxiliary transport data. The clock generator 27 generates, in response to these signals, a system clock signal at least synchronizing with the operation of the inverse transport processor 18. The system clock signal is supplied to a receiving system controller 26 to control the timing of processing elements. <P>COPYRIGHT: (C)2010,JPO&INPIT |
