By monitoring the reception level used when adjusting the antenna of the tuner unit 101 during recording, a sudden level change and a state where no signal can be received are monitored (step 202).

Thereafter, if there is a problem with the monitored reception level, the date and time of occurrence and the reception level data of the reception level are stored in the backup memory 104 (step 203), and this reception level monitoring is repeated during scheduled recording. After the end of the scheduled recording (step 204), it is determined whether there is reception level data of the reception level during the recording after the end of the scheduled recording (step 205).

If there is a problem as a result of monitoring the reception level, a rebroadcast is searched from the EPG to search the same channel (step 206), and a search is performed using the information on the program name and contents. Is the episode of the episode, so the data is also used as a comparison target. When searching other channels, the same program may have slightly different program names and contents in the EPG. Is set by the user, and if it is not found in the EPG within one week, the setting is made to continuously search.

Further, an EPG search (step 206)
Is performed to determine whether or not there is rebroadcast data (step 207). If there is such data, the broadcast date and time of the rebroadcast found from the EPG is set in the recording reservation (step 208). When the broadcast overlaps with the PPV (pay-per-view: pay broadcast for each program) and the recording reservation set by the user, the user's setting is prioritized. In the case of the integrated device 100, the control unit 103 controls the tuner unit. In the case of a separate type device 106, the control unit 103 generates a remote control code and records it on the recording device 107, and starts the recording in conjunction with the video output.
