APPARATUS AND METHOD FOR DISPLAYING IMAGE
First Claim
1. An image display apparatus comprising:
- a tuner for receiving broadcasting signals;
a demodulator for demodulating signals of a channel selected by the tuner;
a demultiplexer for demultiplexing signals demodulated by the demodulator into audio signals, video signals, and a program and system information protocol (PSIP) table;
a controller for controlling information of an electronic program guide extracted from demultiplexed data to be output in the form of an on-screen-display, and dividing the electronic program guide into a text region and a background region to set gradation on the background region of the electronic program guide;
an on-screen-display controller for performing a gradation process on the background region of the electronic program guide using a gradation value set by the controller;
a graphic driver for allowing the electronic program guide on which the gradation process is performed by the on-screen-display controller to be displayed as an image in the form of the on-screen-display; and
an on-screen-display displayer for displaying the on-screen-display representing the electronic program guide delivered from the graphic driver on a screen together with decoded image signals.

Abstract
Provided is an image display apparatus. The apparatus includes a tuner, a demodulator, a demultiplexer, a controller, an OSD controller, a graphic driver, and an OSD displayer. The tuner receives broadcasting signals, the demodulator demodulates signals of a channel selected by the tuner, and the demultiplexer demultiplexes signals demodulated by the demodulator into audio signals, video signals, and a PSIP table. The controller controls information of an electronic program guide extracted from the demultiplexed data to be output in the form of an on-screen-display, and divides the electronic program guide into a text region and a background region to set gradation on the background region of the electronic program guide. The OSD controller performs a gradation process with respect to the background region of the electronic program guide using a gradation value set by the controller. The graphic driver allows the electronic program guide on which the gradation process is performed by the on-screen-display controller to be displayed as an image in the form of the on-screen-display. The on-screen-display displayer displays the on-screen-display representing the electronic program guide delivered from the graphic driver on a screen together with decoded image signals.

6. An image display method comprising:
-
parsing information of an electronic program guide from demultiplexed data; dividing the information of the electronic program guide into a text region and a background region to generate an on-screen-display regarding the electronic program guide; dividing the background region of the electronic program guide into a plurality of regions; setting a gradation value to each of the plurality of regions forming the background region of the electronic program guide to perform gradation on the background region of the electronic program guide; and generating an on-screen-display according to the set gradation value to output the on-screen-display together with decoded image signals on a screen. - View Dependent Claims (7, 8, 9)
