  In S <b> 13, the control module 21 displays the recording reservation table 62 on the screen 7. In S14, the control module 21 determines whether either the normal recording reservation or the group recording reservation is selected. If either one is selected, the process proceeds to S15, and if not selected, the process returns to S14.

  In S15, the control module 21 determines whether or not the broadcast program reserved for recording by the user is a broadcast program that has already started broadcasting at that time. If it is in the middle of the broadcast, the process proceeds to S16, and if it is not in the middle of the broadcast, the process proceeds to S18.

  In S16, it is determined whether or not the program to be recorded in the middle of the broadcast is being accumulated and recorded in the recording device a26 having the first recording area. If it is being accumulated and recorded, the process proceeds to S17. If not accumulated and recorded, the process proceeds to S18. In S17, the control module 21 causes the archive processing module 37 to archive the recording data of the recording target program recorded in the first recording area after the recording target program ends from the start of the program.

  In S18, the control module 21 sets a normal recording reservation.

  In S19, the control module 21 determines which of normal recording reservation or group recording reservation is selected in S14. If the group recording reservation is selected, the process proceeds to S20. If normal recording reservation is selected, the process ends.

  In S20, the control module 21 sets a group recording reservation.

  In S21, the determination module 38 determines whether a broadcast program of the same group as the recording target program has been recorded in the first recording area (recording device a26). If it has been recorded, the process proceeds to S22, and if it has not been recorded, the process ends.

  In S22, the control module 21 determines whether or not recording data that has already been archived exists in the second recording area. The control module 21 determines whether the broadcast program already has recorded data in the second recording area in order to avoid archiving the same broadcast program in duplicate. If the recording data of the broadcast program in the same group as the broadcast program reserved for recording has not been archived, the process proceeds to S23. If recorded data exists, the process ends.

  In S23, the control module 21 causes the archive processing module 37 to archive the same group of broadcast programs recorded in the first recording area. In S21, when there are a plurality of recording data of broadcast programs of the same group, the determination of S22 is performed for each broadcast program, and the processing of S23 is executed according to the result. Then, the process ends.

  As described above, when a broadcast program that the user wants to watch is reserved for recording in a recording area that is not loop recording, if a broadcast program of the same group as this broadcast program is recorded in the recording area of the loop recording, The recorded data of the broadcast program of the same group recorded in the recording area of the loop recording is archived, and the broadcast program of the same group is protected from the automatic deletion function of the loop recording. By doing so, the broadcast program of the same group can be protected from overwriting and erasing the loop recording for the broadcast program desired by the user.
