ABSTRACT:
PCR jitter is improved when writing an input stream TS having a packet with a PCR in a memory10and reading it at a high speed. An oscillator44oscillates a local clock signal having a frequency of a reference clock for the input TS and a counter46counts the local clock signal. When a PCR detection section38detects the PCR in the input TS, a latch circuit42latches a counted value of the counter and a PCR exchange section40exchanges the original PCR with a result of subtracting the latched count value from the PCR of the input TS.
