Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to at least a two-screen display type capable of displaying an image of another channel or an input video signal on a part of a main screen as a sub-screen. In such a television receiver, various setting screens are displayed on a main screen to improve operability. 2. Description of the Related Art Some large television receivers can display another video screen on a part of a display screen.
So-called PIP (picture in picture) or POP
Some (picture out picture) functions are added. Such a television receiver can, for example, capture a child screen being recorded in a main screen, and simultaneously monitor a BS broadcast screen and a general television broadcast screen. In such a television receiver,
When performing channel setting etc. by remote control operation, etc.
The channel setting character screen is superimposed on the main screen and displayed, or the channel setting character screen is displayed on the sub-screen. For example, a specific UHF station is set by a setting button on a remote controller. When the setting is made such that the selection can be made, the selection switch number is superimposed on the screen, and then the key setting is performed by selecting the receiving screen of the 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, there is a problem that the character information is difficult to see. Also, in the method of displaying the setting screen on the sub-screen by the PIP function and performing channel setting, etc., the characters become small and the same becomes difficult to see.
If the character is set to be displayed in large size, the amount of setting information is limited, and the setting method is complicated. SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a parent screen having a large part of a display screen as a display surface and a child screen having a part of the display screen as a display surface. Video signal
In the television receiver to display, operation setting mode is the start of the previous Symbol for setting operation of the television receiver
When it was, to display the setting operation screen on the main screen, before
Was output to the main screen when the setting operation mode was started.
First display control for displaying the video signal on the small screen
Means for determining the setting operation on the setting operation screen.
Determining means and the sub-screen corresponding to the result of the determining means.
So that the video signal displayed in
And the setting operation mode is terminated.
When the setting is completed, the settings displayed on the main screen
Before hiding the operation screen and outputting to the sub-screen
A second display control means for displaying the video signal on the main screen.
And a step . Is provided. According to the present invention, since the control unit as described above is provided, the character information when the setting mode is set is large and clearly displayed. Further, since the video of the broadcasting station for 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. FIG. 1 is a block diagram showing an outline of a television receiver according to the present invention, wherein 1 is a tuner for selectively receiving VHF and UHF broadcasting stations, and 2 is for intermediate frequency amplification and demodulation. 1 shows a video amplifying unit, and an output signal of the video amplifying unit is supplied to Y / C processing units 4A and 4B which perform Y / C separation and chroma signal processing via a video input changeover switch 3A or 3B. The output signal of the Y / C processing section 4A is mainly supplied to the RGB drive circuit 5 as a signal corresponding to the main screen, while the output signal of the Y / C processing section 4B is supplied to the screen signal processing section 6. The video is supplied and converted to the size of the child screen as is well known. When the two-screen mode for simultaneously outputting the parent and child screens is set, the RGB drive circuit 5 switches so that the signal of the screen signal processing unit 6 is superimposed on a predetermined position of the parent screen. It is supplied to CRT7. Reference numeral 8 denotes an externally supplied video signal V1,
5 shows a switch for selecting V2 and V3, 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 a BS broadcast, and the video of the BS channel selected and received is similarly supplied to the video input changeover switches 3A and 3B. [0010] Such a television receiver is entirely controlled by data from a control unit 10 for controlling the system. The control information can be output from a character generator 11 as character / graphic information to a parent or child screen. It has been made like that. In addition, 1
Reference numeral 2 denotes a light receiving unit that receives data transmitted from the remote controller 13. [0011] The television receiver of the present invention can be set to the two-screen display mode in addition to the normal display mode by having the above-described configuration. For example, a television broadcast is displayed on the main screen as a sub-screen. Recording / playback screen of VTR, etc.
Alternatively, a BS program can be displayed, and the reverse operation (replacement of parent and child screens) can be performed. Further, a setting screen for selecting UHF broadcasting with an empty channel button of the remote controller or a setting operation for operating other electronic devices (VTR, laser disk, etc.) with the remote controller can be performed. By the way, the television receiver according to the present invention uses, for example, an empty channel key of
To select an HF broadcast channel, a channel setting key on the remote control may be operated. Then, A in FIG.
Is converted to the two-screen mode, and as shown in FIG. 2B, the image of the parent screen moves to the child screen, and at the same time, the channel setting screen is displayed on the parent screen. Therefore, the user moves the cursor on the channel setting screen and selects a key button and a channel number. Then, the broadcast screen of the selected channel is transferred to the sub-screen each time as shown in FIG. 2C so that the selected screen can be confirmed. Then, when the channel setting end operation is performed, the image selected and set at that time moves to the main screen as shown in FIG. 2D, and the two-screen mode is canceled. Although the above embodiment has been described with respect to the four-screen type in which three small screens can be formed on a horizontally long television receiver, the same operation is performed in the case of a normal parent / child two-screen television. FIG. 3 shows a flow chart of the control unit 10 for performing the setting as described above (F101).
When there is a channel setting input command (F102)
In in performed POP display (F102), (F103), the switch 3A, when switching the 3B to move the main screen on the child screen to switch the main screen to the video input at the same time, the character information for the time channel setting is supplied You. And (F1
When a channel is selected in 05), the image of the selected channel is displayed on the small screen (F106), and at the same time, a new channel is stored (F107). Next, channel setting is completed (F108).
Then, the parent / child screen is returned to the original state, and (F109)
The POP display ends, and the display returns to the normal display mode. In the above embodiment, the setting of the UHF station has been described.
It can also be used for input of a TR or 8 mm reproduced video signal, setting of a BS channel, and the like. Further, the setting of the color of the image, the setting of the brightness, the setting operation of the contrast, and the like can be performed while viewing the setting screen displayed on the small screen. As described above, when the television receiver of the present invention enters the setting mode, the setting screen is displayed on the main screen by the POP function, and the target image to be set on the sub-screen is set.
Because the image is projected, a large amount of character information can be displayed by enlarging the operation screen, and the advantage that the setting operation is not mistaken because the setting target screen is displayed on the sub screen. is there.
