First, a selection item 26 that can be selected only as a higher-level display item shown in FIG. 2 is selected by pressing the cursor button 41 or 43 of the remote controller 36.
Here, the rectangular display area of the selected selection item 26 is displayed larger than the size of the rectangular display area of selection items of the same level other than the selected item. At this time, the setting item 27 at the lower level of the selection item is also displayed at the same time. The size of the display area of the setting item 27 may be an enlargement rate different from the size of the display area of the selection item 26.

  Furthermore, when the selection item 26 is changed, it is changed by pressing the cursor button 41 or 43 of the remote controller 36 again.

  When selecting the selection item 26, for example, as shown in FIG. 2A, when the current upper selection item is a “main body setting” item and all the lower setting items 27 are setting permission items, When the selected setting item is “input 4 terminal setting” 28 and the user presses the cursor button (down) 42, as shown in FIG. 2 (b), the selected setting item is one setting lower. Transition to the state of the item “digital audio output” 29. At this time, the setting item in which the rectangular display area is enlarged is also changed from “input 4-terminal setting” 28 to “digital audio output” 29.

  When the state of the setting item changes from setting permission to setting prohibition in response to an operation for changing from a setting item to a desired setting item by the user, setting is permitted for the rectangular display area of the setting item. The setting item is displayed smaller than the rectangular display area.

  For example, as shown in FIG. 3, when the user is in the analog broadcast viewing state (the state shown in FIG. 3A), the digital broadcast viewing state (the state shown in FIG. 3B) is obtained by pressing the terrestrial digital broadcast network button 38. Since the screen noise removal function “DNR” that is effective only during analog broadcasting automatically transitions from the setting permission item to the setting prohibition item state, the rectangular display area 32 of the setting item is reduced and displayed. .

  In addition, for the setting items that are not permitted to be set, the selection operation by the cursor is also prohibited, and the user selects the “digital audio output” 33 as shown in FIG. When the button 42 is pressed, the setting item “DNR” 34 that is not permitted to be set in the digital viewing state is automatically skipped, and the lower setting item “subtitle display setting” 35 shown in FIG. 4B is selected. Is done.

  In this way, on the menu operation screen, the selected selection item, the setting item that is permitted to be set in a certain operation state of the device, and the size of the display area of the setting item that is not permitted to be set in the operation state By using a unified display format by changing a single attribute in stages, it is possible to visually distinguish the setting items while maintaining the visibility of the setting items, and to improve the operability on the menu operation screen.
