摘要

A transport stream is received and recorded, and the recorded transport stream is reproduced normally. A cycle timer (27) generates a time stamp based on a clock generated by means of a clock generation circuit (28) that is independent of the system clock (4) generated by means of a built-in PLL (7A) of an AV decoder (7), a receiver (22) adds the time stamp to a TS packet, and the TS packet is recorded on a hard disk (42). On the other hand, a transmitter (26) supplies the TS packet read out from the hard disk (42) to the AV decoder (7) by way of a switch (31), MPEG link integrated circuit (16), demultiplexer (5), and FIFO memory (6) at a timing so that the time interval between adjacent TS packets is coincident with that of the time when it was received based on the time stamp added to the TS packet.
