The area code information is described in 'B11-B8' in the EID, and the broadcaster unique number information is described in 'B7-4'. In addition, the area code information is described in 'B11-B8' in the video / data related SID, and the broadcaster unique number information is described in 'B7-4'. In addition, the area code information is described in 'B7-5' in the audio related SID, and broadcaster unique number information is described in 'B4-2'.

When the area code information and the broadcaster unique number information are determined from the broadcast signal, the controller 180 searches for a region name corresponding to the identified area code in the table of Table 1 included in the memory 160 [S114]. .

The controller 180 displays the searched region name and the broadcaster unique number identified in step S113 in the names of broadcast channels of the current region scanned in step S111 [S115].

In this case, the controller 180 may identify the region name and the broadcaster unique number so that the user can easily identify the region name and the broadcaster unique number within the names of the broadcast channels.

For example, the controller 180 displays the region name and the broadcaster unique number at the front or rear end of the broadcast channel names, so that the user can easily identify the region name and the broadcaster unique number within the names of the broadcast channels. can do.

In addition, the controller 180 further emphasizes the font style of the region name and the broadcaster unique number rather than the font style of the broadcast channel names, so that the user can easily identify the region name and the broadcaster unique number within the names of the broadcast channels. You can do that. In this case, the font style includes a display color, a size, an underline, a background color, whether a blinking, transparency, and the like.

The controller 180 groups the broadcast channels marked with the current region name and the broadcaster's unique number into the current region, and stores them in the memory 160 in a list form [S116]. The list is displayed on the display unit 160 [S117].

In this case, the controller 180 may generate a tab window-type list divided by region on one screen, and update broadcast channels in which a current region name and a broadcaster unique number are displayed in a tab window corresponding to the current region in the list.

In addition, the controller 180 may generate folders classified for each region and store broadcast channels in which a current region name and a broadcaster unique number are indicated in a folder corresponding to the current region.

In addition, when displaying a list of broadcast channels in which the region name and broadcaster unique number are displayed, the controller 180 may arrange and display broadcast channels in the list according to a frequency of use of a user or a predetermined importance and priority. have. In addition, the controller 180 may display the sorted order of reception sensitivity of the broadcast channels.
