Abstract
This invention enables the digital broadcast receiving section to restore the reception timing even in a system incapable of guaranteeing the real-time feature of digital broadcast data as far as the 1394 Link. The digital broadcast signal received by the RF section and tuner section is restored to ATM cells at the packeting section. The ATM cells are then sent to the time stamp adding section, which adds the arrival time to the ATM cells. The CPU extracts, as a time stamp, the arrival time of the first ATM cell in each transport packet and creates a 4-byte source packet header on the basis of the value of the arrival time and the value of the CTR in the 1394 Link.
