  Television broadcasts such as terrestrial digital broadcasts are made with broadcast radio waves of different frequencies transmitted from a plurality of broadcast stations. Since the frequency of the broadcast radio wave transmitted from each broadcast station is determined in advance, a channel number is set corresponding to each frequency, and each broadcast station corresponds to each frequency. There are many broadcasting stations throughout the country, and television broadcasting that can be received in each area is limited by the reach of radio waves used for broadcasting. In addition, the channel that can be received and the corresponding broadcasting station may differ depending on the region.

  Normally, in order to receive terrestrial digital broadcasting, broadcasting stations that can be received at the current location are searched by tuning and held as a channel list. However, as described above, since broadcasting stations differ depending on the region such as Kanto and Kansai, Every time the broadcast area changes, it is necessary to switch the channel list.

  On the other hand, simulcasting is currently the center, but as described in Non-Patent Document 1, there is an area-specific one-seg broadcasting demonstration test, etc., which guides users to set channels and watch users. The method to do is being discussed. Although it is possible to use GPS as a means for knowing the current location, there is a problem in that it is a burden on the CPU and power consumption increases in order to simultaneously operate the digital terrestrial function and the GPS function with a mobile phone.

  For example, Patent Literature 1 discloses a television receiver-integrated mobile phone device that selects a channel of the affiliated station when moving outside the service area of a broadcasting station that was viewed before a call. For example, Patent Literature 2 discloses a method for acquiring receivable channel information in a mobile phone with a TV broadcast receiving function that can reduce the number of executions of the receivable channel search process and improve usability.
