Further, in such a television receiver,
When performing channel setting etc. by remote control operation,
The channel setting character screen is displayed superimposed on the parent screen, or the channel setting character screen is displayed on the child screen. For example, a specific UHF station is selected by the setting button of the remote controller. In the case of setting so as to be selectable, a key is set by superimposing a selection switch number on the screen and then selecting an image receiving screen of a desired broadcasting station.

[0004]

By the way, as described above, when the set character is superimposed on the main screen,
Since the image as the background changes, the problem that the character information is difficult to see occurs. Also, in the method of displaying the setting screen on the sub screen by the PinP function and performing the channel setting etc., the characters become small and it becomes difficult to see likewise.
If the setting is made so that the characters are displayed in large size, the amount of setting information is limited and the setting method becomes complicated.

[0005]

In order to solve such a problem, the present invention displays a parent screen showing most of the display screen and a child screen having a part of the parent screen as a display surface, In a television receiver that is controlled so that at least the image of the parent screen and the image of the child screen can be exchanged, when entering various operation setting modes of the television receiver, the setting operation screen is changed to the parent screen. A television characterized by being provided with a control unit for displaying and controlling the video of the main screen output at the time of setting to move to the sub screen, and changing the video of the sub screen in accordance with the setting operation. A receiver is provided.

[0006]

Since the present invention is provided with the control section as described above, the character information when the setting mode is set is large and is clearly displayed. Further, since the image of the broadcasting station on which the setting operation is performed is displayed in the sub-screen, the key setting can be performed while watching the screen of the selected channel, and the reliable operation can be performed.

1 is a block diagram showing an outline of a television receiver according to the present invention, in which 1 is a tuner for selectively receiving VHF and UHF broadcasting stations, and 2 is an image amplification section for performing intermediate frequency amplification and demodulation. The output signal of the video amplification unit is supplied to the Y / C processing units 4A and 4B which perform Y / C separation and chroma signal processing via the video input changeover switch 3A or 3B.

The output signal of the Y / C processing unit 4A is supplied to the RGB drive circuit 5 mainly as a signal corresponding to the parent screen, while the output signal of the Y / C processing unit 4B is supplied to the screen signal processing unit 6. The supplied image is converted to the size of the small screen as is well known. Then, when the two-screen mode for simultaneously outputting the parent and child screens is set, the signal of the screen signal processing unit 6 is switched by the RGB drive circuit 5 so as to be superimposed on a predetermined position of the parent screen, It is supplied to the CRT 7.

Reference numeral 8 is a video signal V1 supplied from the outside.
A switch for selecting V2 or V3 is shown, and only the selected video signal is supplied to the video input changeover switch 3A or 3B. Reference numeral 9 denotes a BS tuner for receiving BS broadcasting, and the selectively received BS channel image is similarly supplied to the image input changeover switches 3A and 3B.

Such a television receiver is entirely controlled by the data from the control unit 10 which controls the system, and the control information can be output from the character generator 11 as character / graphic information on the parent or child screen. It is done like this. 1
Reference numeral 2 denotes a light receiving unit for receiving the data transmitted by the remote controller 13.

By providing the television receiver of the present invention with the above-described structure, it is possible to set the two-screen display mode in addition to the normal display mode. For example, the television broadcast is displayed on the main screen as the sub-screen. Recording / playback screen of VTR,
Alternatively, the BS program can be displayed, and the reverse operation (replacement of parent / child screen) can be performed. Further, it is possible to perform a setting screen for selecting UHF broadcast by the empty channel button of the remote controller and a setting operation for operating other electronic devices (VTR, laser disk, etc.) by the remote controller.

By the way, the television receiver of the present invention uses, for example, an empty channel key of a remote controller to make a U
