Abstract

In a display apparatus, an Electric Program Guide (EPG) is distinctively displayed to overlap with current broadcasting data being displayed. A method for displaying EPG includes determining whether an EPG display request signal is received while broadcasting data is displayed. When the EPG display request signal is received, at least one of brightness and chroma of a screen displaying the broadcasting data is modified. The EPG is displayed on the screen so that the displayed EPG has a different brightness or chroma than the modified brightness or chroma of the screen. This may improve recognizability and/or legibility of EPG by employing a modification in brightness or chroma when the EPG is displayed on current broadcasting data. For further improved recognizability and/or legibility, a border effect or a blur effect may be applied to a user'"'"'s selected item in the displayed EPG.

Claims

1. A method for displaying an Electric Program Guide (EPG) on a display apparatus, the method comprising:

determining whether an EPG display request signal is received while broadcasting data is displayed;

modifying at least one of brightness and chroma of a screen displaying the broadcasting data when the EPG display request signal is received; and

displaying the EPG on the screen so that the displayed EPG has a different brightness or chroma than the modified brightness or chroma of the screen.

2. The method of claim 1, wherein, if the at least one of brightness and chroma of the screen are modified such that the at least one of brightness and chroma of a screen are reduced, the EPG is displayed on the screen with a brightness and chroma that is greater than the modified at least one of brightness and chroma of the screen.

3. The method of claim 1, wherein, if the at least one of brightness and chroma of the screen are modified such that the at least one of brightness and chroma of a screen are increased, the EPG is displayed on the screen with a brightness and chroma that is less than the modified at least one of brightness and chroma of the screen.

4. The method of claim 1, further comprising:

applying a border effect to a user'"'"'s selected item in the displayed EPG so that outer edges of the user'"'"'s selected item have a different color from that of the user'"'"'s selected item.

5. The method of claim 4, wherein the applying of the border effect further comprises applying a blur effect to the outer edges of the user'"'"'s selected item.

6. The method of claim 1, further comprising:

discontinuing the display of the EPG when an EPG display cancel signal is received; and

reestablishing brightness or chroma of the screen to a brightness or chroma of the screen from before the EPG display request signal was received.

7. The method of claim 1, further comprising:

adding a cursor to a user'"'"'s selected item in the displayed EPG.

8. The method of claim 7, wherein the cursor is located adjacent to one side of the user'"'"'s selected item.

9. The method of claim 1, further comprising:

receiving a broadcast signal;

dividing the received broadcast signal into broadcasting data and the EPG; and

displaying the broadcasting data on the screen.

10. The method of claim 1, wherein the at least one of brightness and chroma are modified based on a user setting.

11. A display apparatus, the apparatus comprising:

a display unit for simultaneously displaying broadcasting data and Electric Program Guide (EPG) data;

a broadcast signal receiver for receiving a broadcast signal and for dividing the broadcast signal into the broadcasting data and the EPG data;

a tuner for receiving the broadcasting data from the broadcast signal receiver and for sending current broadcasting data of a selected channel to the display unit;

an EPG processing unit for receiving the EPG data from the broadcast signal receiver and for delivering the EPG data to the display unit when an EPG display request signal is received; and

a control unit for modifying at least one of brightness and chroma of a screen displaying the broadcasting data when the EPG display request signal is received, and for controlling the display unit to display the EPG on the screen so that the displayed EPG has a different brightness or chroma than the modified brightness or chroma of the screen.

12. The apparatus of claim 11, wherein, if the at least one of brightness and chroma of the screen are modified by the control unit such that the at least one of brightness and chroma of a screen are reduced, the control unit controls the display unit to display the EPG on the screen with a brightness and chroma that is greater than the modified at least one of brightness and chroma of the screen.

13. The apparatus of claim 11, wherein, if the at least one of brightness and chroma of the screen are modified by the control unit such that the at least one of brightness and chroma of a screen are increased, the control unit controls the display unit to display the EPG on the screen with a brightness and chroma that is less than the modified at least one of brightness and chroma of the screen.

14. The apparatus of claim 11, wherein the control unit applies a border effect to a user'"'"'s selected item in the displayed EPG so that outer edges of the user'"'"'s selected item have a different color from that of the user'"'"'s selected item.

15. The apparatus of claim 14, wherein the control unit applies a blur effect to the outer edges of the user'"'"'s selected item.

16. The apparatus of claim 11, wherein the control unit discontinues the display of the EPG when an EPG display cancel signal is received, and reestablishes the brightness or chroma of the screen to a brightness or chroma of the screen from before the EPG display request signal was received.

17. The apparatus of claim 11, wherein the control unit adds a cursor to a user'"'"'s selected item in the displayed EPG.

18. The apparatus of claim 17, wherein the cursor is located adjacent to one side of the user'"'"'s selected item.

19. The apparatus of claim 11, wherein the control unit modifies the at least one of brightness and chroma based on a user setting.
