Abstract
A processor detects a data error in the TS packet by utilizing a value of 'adaptation_field_control' and a value of 'adaptation_field_length' included in the TS packet of a transport stream. A TS packet filter of the processor deletes the relevant TS packet in the transport stream if the data error in the TS packet is detected, and outputs the relevant TS packet to a PID filter if the data error in the TS packet is not detected. The PID filter detects PCR (Program Time Clock) from the TS packet. In a period of time when the PCR does not arrive at a clock reproducer, a frequency of a reference clock when the last PCR arrived is maintained, and then, when the PCR arrives at the clock reproducer, a value of STC (System Time Clock) is set and the frequency of the reference clock CK is controlled by the clock reproducer such that the value of the STC becomes equal to a value of the new PCR.
