Similarly, if the user selects repeat recording every day, the current time is 9: 1. Record from 8 to 10:00, which is the end time of the program you are currently watching, and stop However, from the next day, the broadcast time of the program you are currently watching is from 9:00 to 10:00. Record with. Similarly, if the user chooses to repeatedly record at the same time every week, From the current time 9:18 to 10:00, which is the end time of the program you are currently watching After recording, the program was stopped, and after the same day of the next week, it is the broadcast time of the program currently being viewed. Recording is performed from 9:00 to 10:00.

[0033]   With such a configuration, the user can record the program currently being viewed. In the same time period as the broadcast time of the same program, it is set to record repeatedly after the next day. Can be set. As a result, it is necessary to separately make a reservation recording of the broadcast from the next day. The recording reservation operation can be easily performed. Furthermore, based on broadcast time You can set repeated recording to, so it will be broadcast daily at the same time. , Programs with different program names and contents (for example, 19:00 to 20: If you want to record each program, etc. broadcasted on 00, you must make a recording reservation for each program. This eliminates the need for recording reservation operation.

[0034]   Further, the control unit 8 sets the recording reservation criteria to the broadcast time, the program title, and the program content. If you choose to record repeatedly daily or weekly, you are currently watching After recording the program, the broadcast time of the program reserved for recording will change in the program information. Even if it is changed, this program information is read and the changed broadcast time is stored in the memory 10. Let This will ensure that the next and subsequent broadcasts of the program you are watching are recorded. Wear.
