ABSTRACT:
In a digital broadcast multiplexing apparatus for multiplexing a plurality of programs on a single physical channel so as to broadcast the digital multiplexed broadcasting program, there are provided with an apparatus for correcting positions of PCR packets contained in transport streams within the respective programs, and a PCR correction value forming apparatus for applying values of correcting PCR values with respect to a result of the position corrections in order to simply execute a function capable of uniformly synchronizing the PCR packets contained in the transport streams and capable of viewing the received programs without any interruption on the reception side even when a tuning operation is carried out. Then, the digital broadcast multiplexing apparatus outputs such a broadcast program packet stream which has been multiplexed as a single broadcast program in such a manner that the PCR packets are synchronized with each other among the plurality of programs.
