Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a high definition television receiver.

Conventional technology High-definition television displays detailed television images on a large wide screen to provide new appeal such as power and realism that cannot be obtained with current television broadcasting. Interest is increasing in all countries. This high-definition television was proposed by the Japan Broadcasting Corporation (NHK), and has a screen aspect ratio of 5:3 (or 16:9) (hereinafter referred to as 6:3) and 1125 scanning lines. Current standard TV (aspect ratio 4:3.
(526 scanning lines).

FIG. 4 shows a schematic configuration for displaying current standard television signals on a conventional high-definition television receiver. The current standard television signal is input to the current standard television signal input terminal 41, and then the signal conversion circuit 43 converts the scanning line into 6
Performs scan conversion to double the number of lines from 25 to 1060 lines. Then, the converted signal and the high-definition television system signal are switched by the switching circuit 44 and displayed on the high-definition display 43.

Next, FIG. 3 shows a state in which a current standard television signal scan-converted is displayed on a high-definition display. In Fig. 3, numeral 31 is a high-quality display screen with an aspect ratio of 6:3, and the aspect ratio 4: which has been scan-converted from this screen.
Since the aspect ratio is different from the current standard TV signal of 3, the screen of the current standard TV when the vertical length of the screen is the same, and the screen of the current standard TV when the horizontal length of the screen is the same. 33 are respectively displayed on a high-definition display 46 as shown in FIG. 3 a, l).

The problem that the invention aims to solve However, with the above configuration, high quality D.

If you project any image of the current standard ten on Spray 45, the third
As shown in Figure A, no image is displayed on both the left and right edges (shaded area) of the screen of a high-definition display, or as shown in Figure 3, both the top and bottom edges (shaded area) of the current standard TV image are displayed. However, this method has problems such as missing necessary images.

In view of the above-mentioned problems, the present invention provides that when displaying current standard TV images on a high-definition display, the images at both the left and right ends of the screen are not cut off due to the difference in aspect ratio. A high-definition television receiving apparatus of the present invention is capable of displaying high-definition television signals in order to solve the above-mentioned problems. Displays scan-converted current standard television images on the display, and also controls multiple devices connected via buses to the left or right side of the display screen where images do not appear due to differences in aspect ratio. It is characterized by displaying information and making it possible to control various devices by operating the remote control unit.

According to the above-mentioned structure, the present invention makes it possible to display the current standard television image on a high-definition television receiver by making the vertical length of the screen the same so that the image at both the upper and lower ends of the screen is not cut off. and set either the left or right edge of the screen as the part where no image is generated. Then, display the control information of various devices connected through the bus in this area, and use it as a table chart for remote control operation to create an image on the left or right edge of the display screen and make effective use of the area next to it. It can be done.

Embodiment Hereinafter, a high-definition television receiving apparatus according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram showing an image projected on a display screen of a high-definition television receiver according to an embodiment of the present invention. In Fig. 1, 11 is the screen of a high-definition display;
2 is the part that displays the current standard television image, 13
is a part that displays control information for various devices.

FIG. 2 is a schematic diagram of a high-definition television receiving apparatus according to an embodiment of the present invention. In the figure, 26 is a device a that is an example of a device connected to the high-definition television receiver through a bus, 27 is a two-way information transmission circuit between the high-definition television receiver and the device, 28 is a composite screen creation circuit, 29 is a remote control receiving terminal, 30 is a remote control, and the rest is the same as that of the conventional example shown in FIG.

The high-definition television receiving apparatus configured as above will be explained below with reference to FIGS. 1 and 2.

The current standard television signal inputted from the current standard television signal input terminal 22 is subjected to signal conversion processing such as scanning conversion by the signal conversion circuit 23, and is inputted to the composite screen creation circuit 28.

On the other hand, the control information of a plurality of devices, of which device (4) 2s is an example, is input to the composite screen creation circuit 28 via the bidirectional information transmission circuit 27 via the bus, and the signal conversion circuit 23 performs signal conversion processing such as scan conversion. The video information of the current standard television signal that has been processed is synthesized, and the switching circuit 24 switches it to a high-definition television signal and displays it on the high-definition display 2.
The video information of the current television signal is displayed on the current standard television video projection section 12 of No. 5, and the device control information display section 1
3, control information for a plurality of devices is displayed.

When the user of the high-definition television receiver operates the remote control 30 in response to the control information of this device, the operation details are input to the two-way information transmission circuit 27 via the remote control reception terminal 29, and the operation details of the remote control 30 are The corresponding control is transmitted to the devices (a) 2e, and the change in the control content of the device a is also transmitted to the composite screen creation circuit 28,
The display content of the device control information display section 13 is changed.

Effects of the Invention As described above, according to the present invention, when displaying current standard television signals on a high-definition television receiver, high-definition display reception is performed via a bus on the left or right part of the display screen where no image is displayed. By showing control information for various devices connected to the device and using it as a table chart for control operations using a remote control, the display screen can be used effectively without missing current standard television signals. can do 0
