- step S37 it is determined whether or not the operation is to change the acquisition time of the EPG data of the CS channel.
- multiple candidate times are displayed from the time zone that does not overlap with the acquisition time of the terrestrial EPG data, Either one can be selected from the time (step S38).
- step S39 it is determined whether or not there is a recording reservation for a time overlapping with the acquisition time zone set at that time.
- a warning indicating that the recording reservation overlaps
- the notification is displayed on the setup screen at that time (step S40). The display of this warning may be accepted from the user. If accepted, the recording reservation is canceled (step S55). If not, return to step S35. If the consent is not accepted, the process proceeds to step S55.
- the user confirms from the warning display that the acquisition time zone of the EPG data and the recording reservation overlap, the user does not operate properly by changing the acquisition time of the EPG data or the recording reservation time. Can be avoided.
- the controller 122 determines whether or not it is time to acquire terrestrial EPG data from the time when the clock section 124 counts (step S41), and acquires terrestrial EPG data. Wait until the time is reached. Then, when it is determined that the time to acquire the terrestrial EPG data has come, the tuner 101 receives a channel for acquiring the terrestrial EPG data registered in advance (step S42). With this reception, EPG data is obtained (step S43). This acquisition process is started, and it is determined whether or not all the EPG data of one unit has been acquired (step S44), and the process is performed until the acquisition is completed. In the case of this example, the electronic program guide data for all channels broadcast in the area (except for some channels that do not have EPG data) from the day to one week ahead is acquired.

- One channel It takes, for example, about one minute to acquire one week's worth of electronic program guide data.
- the acquisition process in step S55 until one week's worth of electronic program guide data for the corresponding channel can be acquired I do.
- the one week's worth of EPG data is stored on the hard disk (step S57).
- step S58 it is determined whether or not the next smallest channel number among the registered reception channels is the same broadcast service channel as the channel number from which the EPG data was obtained immediately before (step S58). If it is a broadcasting service, switch to reception of the front motion channel of another broadcasting service (step S59). «Here, if a CS tuner that requires satellite switching operation is connected, It is necessary to send a channel switching command after sending a satellite switching command.
- step S58 If it is determined in step S58 that the broadcasting service is the same, and after the processing in step S59, processing for acquiring EPG data for the channel acquired at that time is performed (step S6). 0), it is determined whether or not the data of the electronic program guide for the channel number up to one week from the day has been obtained (step S61). When one week's worth of electronic program guide data for the corresponding channel has been obtained, the one week's worth of EPG data is stored on the hard disk (step S62).
- step S58 to step S62 The processing from step S58 to step S62 is repeated as long as there is a channel registered to receive.
- the maximum number of CS broadcast channels that can be registered is 20, so the EPG data acquisition processing is performed a maximum of 20 times. If EPG data for all registered channels can be obtained and saved on the hard disk, the power is turned off to the CS channel device 200. Is sent (step S63), and the CS tuner 200 is set to the standby state. However, if the power supply of the CS tuner device 200 is set to be unlinked, the processing in step S63 is not necessary.
- the EPG data stored on the hard disk is subjected to a data reduction process to convert the EPG data into a data format that can be easily used by the hard disk recording / reproducing device 100 (step S64).
- the EPG data acquisition process ends. If it takes about 1 minute to acquire the EPG data for one CS channel, it is possible to register up to 20 channels, so it takes about 20 minutes to receive, and the subsequent step S 6 For example, it takes about 10 minutes to organize the data in 4, and it takes about 30 minutes in total.
- the EPG data can be stored in the hard disk recording / reproducing device 100, and the program guide is displayed on a connected television receiver or the like based on the stored EPG data. Then, by selecting the program to be recorded from the displayed program guide by GUI operation or the like, the program to be reserved for recording can be easily selected.
