ABSTRACT:
A transport stream (TS) is recorded and the recorded TS is reproduced simultaneously. An input PID parser extracts the first packet only to be recorded, the second packet to be recorded and to be used for controlling, and the third packet to be used only for controlling from among the TS packet that constitutes the TS supplied from a descrambler. The first and second packets are supplied to a receiver and supplied to a hard disk drive (HDD) for recording. The second and third packets are supplied to an MUX. On the other hand, the TS packet stored in the HDD is read out and supplied to the MUX by way of an output PID parser. The MUX multiplexes the second or third packet supplied from the input PID parser and the TS packet read out from the HDD, and supplies the multiplexed packet to a CPU that controls a descrambler or the like.
