Abstract
The present invention is an apparatus and method to remove delay fluctuations generated on a plurality of networks. A reception apparatusreceives ATM cells transmitted through a network-and a network-, converting the cells into a transport stream. At that time, the reception apparatusexpresses a PCR packet's timing of arrival at the reception apparatusby 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 network-. The reception apparatusalso computes a new PCR value W on the basis of the count value and the phase-difference information used as synchronization information. The reception apparatusthen 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.
