The data stored in the broadcast station code / region code storage unit 106 includes a broadcast station code and a character string representing a region code corresponding to the broadcast station code, and has a format of “broadcast station code // region code”. It consists of.

For example, as shown in FIG. 3, when an ADAMS broadcast is detected by the broadcast station code acquisition unit 105, the broadcast station code is "317" and the broadcast station code is "317".
Is “Osaka, Nara”, so the broadcast station code / area code 103 stores “317 // Osaka, Nara” as data.

The operation of the region-specific broadcast channel setting device configured as described above will be described. First, when the regional broadcast channel setting device is activated, the channel selection unit 101 sequentially tunes in from low frequency broadcast channels. The channel pattern acquisition unit 102 determines that the channels 2, 4, and 6 among the channels selected by the channel selection unit 101 can be received, and sets the first area code acquisition unit 104 as the channel pattern “2, 4, 6”. Output to Then, the first area code obtaining unit 104 outputs the area code “Osaka,” corresponding to the channel pattern “2, 4, 6” output from the channel pattern obtaining unit 102.
“Hyogo, Kyoto” is obtained from the channel pattern / area code storage unit 103 and output to the area code comparison unit 108.

The broadcast station code acquisition section 105 detects an ADAMS broadcast wave on channel 6 among the channels selected by the channel selection section 101. Then, the broadcast station code “31” included in the detected ADAMS broadcast wave
7 ”and outputs it to the second area code acquisition unit 107. Then, the second area code acquisition unit 107 outputs the broadcast station code “31” output from the broadcast station code acquisition unit 105.
The area code “Osaka, Nara” corresponding to “7” is acquired from the broadcast station code / area code storage unit 106 and output to the area code comparison unit 108.

The area code comparing section 108 has an area code "Osaka, Hyogo, Kyoto" obtained by the first area code obtaining section 104 and an area code "Osaka, Nara" obtained by the second area code obtaining section 107. And outputs a matching area code “Osaka” to the area-specific broadcast channel data acquisition unit 110. Then, the area-specific broadcast channel data acquisition section 110 outputs the area-specific broadcast channel data “2-NHK Osaka, 4-Mainichi broadcast, 6-Asahi broadcast” corresponding to the area code “Osaka” output from the area code comparison section 108. From the region code / region-based broadcast channel data storage unit 109 and output to the channel setting unit 111. And
