Further, as shown by an arrow B in FIG. 3, when moving from the service area 3 to the service area 2 of the base station 12, the service area of the broadcasting station does not change. Therefore, the broadcast receiving unit 300
There is no need to change the settings of the physical channels in.

Next, referring to FIG. 4, the portable terminal device 30
The operation of will be further described.

The mobile terminal device 30 includes a mobile phone transmitting / receiving unit 2
00, the area identification information is received every predetermined time (S
11). The operation of receiving the area identification information is a well-known mobile phone function originally possessed by the mobile phone transmitting / receiving unit 200, and is usually executed during the standby operation. The mobile phone transmitting / receiving unit 200 receives the area identification information,
The service area of the base station is recognized and the mobile station number is registered in the base station.

When the mobile phone transceiver 200 receives the area identification information, the area identification information is supplied from the mobile phone transceiver 200 to the first controller 220. The first control unit 220 compares the area identification information supplied from the mobile phone transmission / reception unit 200 with the area identification information registered in advance in the first storage unit 250 (S12, S13). As a result, when they match, that is, when the same area identification information as the previous time is received, the first control unit 220 supplies a match signal to the AID / CH conversion unit 310. AID
The / CH converter 310 does not change the physical channel according to the coincidence signal. Therefore, the second control unit 320 is
Due to the non-conversion operation of the ID / CH conversion unit 310, the setting of the physical channel of the broadcast reception unit 300 is not changed (S1).
4, S15).

On the other hand, as a result of comparing the two area identification information in step S13, if they do not match, the first control section 220 sets the new area identification information as the first area identification information.
To the storage unit 250 and update the area identification information (S
16). At the same time, the first controller 220 sends the mismatch signal and the new area identification information to the AID / CH converter 3
Output to 10. The AID / CH conversion unit 310 changes the physical channel information of the broadcasting station group according to the new area identification information. That is, the broadcast channel information corresponding to the newly supplied area identification information is read from the memory (S17). The second control unit 320 stores the physical channel information of the new broadcast group supplied from the AID / CH conversion unit 310 in the second storage unit 330 (S1).

There are, for example, two types of channel setting methods for the ten keys constituting the input unit 260. In the first method, the physical keys are assigned in ascending order of the frequencies of the physical channels. In this case, when the service area of the broadcasting station changes, the relationship between the number of the numeric keypad as the channel selection means and the physical channel changes. On the other hand, in the second setting, the physical channel and the number of the ten-key pad of the broadcasting station broadcasting the program of the same content are set without changing in different service areas. Since the operation after setting the physical channel is the same as the processing described in FIG. 11, the description will be omitted.

According to the first embodiment, the portable terminal device 30 has the portable telephone device 31 and the broadcast receiving device 32, and when the acquired regional identification information is changed by the portable telephone device 31, the AID is used. The / CH conversion unit 310 generates physical channel information of the broadcasting station corresponding to the new area identification information. Therefore, the physical channel information of the broadcast receiving unit 300 can be automatically changed by using the generated physical channel information. Therefore, even if the service area of the broadcasting station changes frequently, there is an advantage that a complicated change work as in the past is not required.

The physical channel information of the broadcasting station group corresponding to the area identification information can be downloaded. Therefore, AI
The D / CH conversion unit 310 does not need to store broadcast channel information corresponding to all area identification information. Therefore, the storage capacity of the memory can be reduced.

Even if the service area described in the first embodiment is changed in the database, for example, the number of the ten key as the channel selection means of the mobile terminal device 30 and the program having the same content in each service area are always displayed. Information for setting the physical channel of the broadcasting station that is broadcasting may be stored, and this information may be downloaded together with the physical channel information of the broadcasting station group.

Further, it is more convenient if the database stores auxiliary information such as program information and advertisement information at a broadcasting station in the area, and the additional information can be downloaded. In this case, for example, when the power of the broadcast receiving device 32 is turned on, the acquired program information and advertisement information can be displayed on the display unit 230 and presented to the viewer. Further, the additional information can be displayed when the viewer specifies the display, or automatically when the reception state of the broadcast wave deteriorates.
