Abstract

A device and method for modifying a video image of a display apparatus method, for efficiently modifying a size and aspect ratio of a video image, is disclosed. The device includes an on-screen display (OSD) generator providing an on-screen display (OSD) on a display for programming a size and an aspect ratio of a video image, and a video processor modifying a displayed video image in accordance with the size and aspect ratio of the displayed video image programmed by a user. Herein, the video processor modifies the video image from a center point of the video image.

Claims

1. A device for modifying a video image of display apparatus, comprising:

a demultiplexer dividing received broadcast signals into a video signal, an audio signal, and supplementary information;

a video processor converting the video signal received from the demultiplexer into a displayable signal;

a microcomputer controlling the video processor so as to adjust a size and aspect ratio of a displayed video image based on the supplementary information received from the demultiplexer; and

a data processor providing a video image modifying menu for allowing a user to remotely change the size and aspect ratio for a currently displayed video image.

2. The device according to claim 1, wherein the microcomputer adjusts the size and aspect ratio of a displayed video image based on a genre information included in broadcast programs.

3. The device according to claim 1, further comprising a memory storing a video size value and a video aspect ratio value corresponding to each genre of broadcast programs.

4. A device for modifying a video image of display apparatus, comprising:

a demultiplexer dividing received broadcast signals into a video signal, an audio signal, and supplementary information;

a video processor converting the video signal received from the demultiplexer into a displayable signal;

a microcomputer controlling the video processor so as to adjust a size and aspect ratio of a displayed video image based on the supplementary information received from the demultiplexer; and

a data processor providing a video image modifying menu for programming and storing a video size and a video aspect ratio for each genre of broadcast programs.

5. The device according to claim 4, wherein the video image modifying menu includes an item for programming a position of subtitles.

6. The device according to claim 4, wherein the video image modifying menu includes an item for changing a color of upper and lower portions of the displayed video image initially shown as a black screen.

7. A method for modifying a video image of a display apparatus, comprising:

dividing received broadcast signals into a video signal, an audio signal, and supplementary information;

converting the video signal for adjusting a size and aspect ratio of a displayed video image based on a genre information of broadcast programs included in the supplementary information; and

providing a video image modifying menu for allowing a user to remotely change the size and aspect ratio for a currently displayed video image.

9. The method according to claim 7, further comprising programming and storing a video size and a video aspect ratio for each genre of broadcast programs.

8. A method for modifying a video image of a display apparatus, comprising:

dividing received broadcast signals into a video signal, an audio signal, and supplementary information;

converting the video signal for adjusting a size and aspect ratio of a displayed video image based on a genre information of broadcast programs included in the supplementary information; and

displaying a video image modifying menu for programming and storing a video size and a video aspect ratio for each genre of broadcast programs.
