PCR jitter is improved when writing an input stream TS having a packet with a PCR in a memory 10 and reading it at a high speed. An oscillator 44 oscillates a local clock signal having a frequency of a reference clock for the input TS and a counter 46 counts the local clock signal. When a PCR detection section 38 detects the PCR in the input TS, a latch circuit 42 latches a counted value of the counter and a PCR exchange section 40 exchanges the original PCR with a result of subtracting the latched count value from the PCR of the input TS.
