Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display suitable for application to, for example, a television receiver capable of receiving not only general television broadcasting but also satellite broadcasting. Related to the device. 2. Description of the Related Art In recent years, television receivers capable of receiving satellite broadcasts in addition to general television broadcasts such as VHF and UHF have been proposed. [0003] Such a television receiver has a satellite broadcast receiving unit for receiving satellite broadcasts, in addition to a general television broadcast tuner. In such a television receiver, after a mechanical switch is turned on (called a standby state or the like), for example, a main power supply can be turned on or off by a remote controller or the like. . When the main power supply is turned on, power is supplied to a general television broadcast tuner and a satellite broadcast receiving unit, respectively, which perform reception and output operations.
When the main power is turned off, the power supply to the general television broadcast tuner and the satellite broadcast receiving unit is stopped, and the reception and output operations thereof are stopped. Further, in this television receiver, a remote controller or the like is operated to receive a desired reservation program at a desired reservation time, adjust colors, adjust volume, etc. The settings can be made. [0007] A desired item of these items is projected on, for example, a display screen, and parameters and the like of the projected item can be set. [0008] Incidentally, in a television receiver having many setting items as described above, simplification of setting operation is desired. As a method of simplification, for example, a setting item is projected as a menu on the display screen, and a desired item is selected from each item of the menu by moving, for example, a cursor.
After the determination, an image for the selected item is projected, and parameters and the like are set on this image. However, when such a setting method using a menu image is adopted, a hierarchical structure is adopted. Therefore, a certain item is selected and determined in the menu image as the first hierarchy, and the image of the nth hierarchy is projected. At times, a line indicating this item and an item for returning to the original hierarchy are required, which causes an inconvenience that the amount of displayed information such as the number of lines increases. The present invention has been made in view of such a point, and a projection indicating an item for returning to the previous screen and a projection indicating the currently selected item are combined into one, for example, a line. An object of the present invention is to propose a display device capable of reducing the amount of projected information such as the number. According to the present invention, there is provided a display device, as shown in FIGS. 1 to 5, for setting items and corresponding to the setting items.

By selecting and determining the displayed graphic marker, the screen of the immediately preceding hierarchy is displayed. According to the present invention described above, the screen one step before is displayed by selecting the graphic marker corresponding to the item, so that the item for returning to the screen one step before is displayed. And the projection indicating the currently selected item can be combined into one to reduce the amount of projection information such as the number of lines. An embodiment of the display device according to the present invention will be described below in detail with reference to FIG. In FIG. 1, reference numeral 1 denotes an antenna which receives a television high-frequency signal in a VHF band or a UHF band. This television high-frequency signal is supplied to a tuner 2.
