ABSTRACT:
The present invention is an apparatus and method to remove delay fluctuations generated on a plurality of networks.A reception apparatus22receives ATM cells transmitted through a network4-1and a network4-2, converting the cells into a transport stream. At that time, the reception apparatus22expresses a PCR packet's timing of arrival at the reception apparatus22by a count value obtained as a result of counting the number of clock pulses (clock pulses Nr) synchronous with a network clock signal of the network4-2. The reception apparatus22also computes a new PCR value W on the basis of the count value and the phase-difference information used as synchronization information. The reception apparatus22then computes a new PCR value X on the basis of an original PCR value E recorded from the beginning on the encoding side and the PCR value W, newly recording the PCR value X.
