Abstract

A video display device includes: an image display device including: a signal operating unit which operates image quality of a source image; a first OSD unit which generates a first OSD signal; a control unit for controlling the image display device, and a memory which is connected to the control unit; and a video device including: a second OSD unit which generates a second OSD signal; and a video device control unit for controlling the video device, wherein the OSD signal output is always displayed with constant image quality, image quality data of the second OSD display stored in the memory is used as the image quality data of the signal operating unit when the second OSD display is performed, and, if the OSD display is finished, the image quality data of the display returns to the image quality data of the source image.

Claims

1. A video display device including a video device comprising:

a TV receiver including;

a tuner which demodulates a radio wave received through an antenna;

an external device connecting terminal connected to an external device;

a selector which is connected to the tuner, the external device connecting terminal and a DVD playback unit, receives source signals output from the tuner, the external device connecting terminal and the DVD playback unit, and selects and outputs any one of the source signals;

a signal operating unit which operates the source signal output from the selector to have predetermined image quality and outputs the operated source signal;

an image display unit which displays an image based on the source signal output from the signal operating unit;

a first OSD unit which outputs a first OSD signal which is a setting display signal of the TV receiver to the signal operating unit;

a control unit for controlling the respective units;

a memory which is connected to the control unit and stores data, and

an external input unit for transmitting an external operation instruction signal to the control unit;

the DVD playback unit including;

a motor for rotating a DVD medium;

a pickup unit for reading data recorded in the DVD medium;

a decoder for decoding the data read by the pickup unit and transmitting the data to the selector as the source signal;

a second OSD unit which is provided in parallel to the decoder and outputs a second OSD signal which is a setting display signal of the DVD playback unit to the selector; and

a DVD control unit for controlling the respective units, wherein;

the control unit and the DVD control unit are connected to each other and, when the OSD signal input to the external input unit is input to the control unit, source image display, the first OSD display, and the second OSD display are sequentially repeated;

the OSD signal output from the first OSD unit is always displayed with constant image quality;

when the display is switched to the second OSD display, the control unit transmits the second OSD signal to the DVD control unit and the second OSD display is performed based on image quality data of the second OSD display stored in the memory;

when the second OSD display is finished, the image quality data of the signal operating unit returns to the image quality of the source image before the OSD display is performed; and

the image quality data of the second OSD display is the same or the substantially same as that of the first OSD display.

2. A video display device including a video device comprising:

an image display device including;

a signal operating unit which operates image quality of a source image based on image quality data;

a first OSD unit which generates a first OSD signal for setting the image display device;

a control unit for controlling the image display device, and a memory which is connected to the control unit and stores various data; and

a video device including;

a second OSD unit which generates a second OSD signal for setting the video device; and

a video device control unit for controlling the video device, wherein

the OSD signal output from the first OSD unit is always displayed with constant image quality, the image quality data of the second OSD display previously stored in the memory is used as the image quality data of the signal operating unit when the second OSD display is performed, and, if the OSD display is finished, the image quality data of the display returns to the image quality data of the source image.

3. The video display device according to claim 2, wherein

the image quality data of the second OSD display is the same or the substantially same as that of the first OSD display.

4. The video display device according to claim 2, wherein

the image quality data of the second OSD display can be optionally set by a user.

5. The video display device according to claim 2, wherein

the image quality data of the second OSD display can be optionally selected from a plurality of image quality data which are previously prepared by a user.
