Abstract

A display apparatus and a multi-view providing method are provided. The display apparatus includes a signal processing unit for constructing an image frame of first image content; a display unit for displaying the image frame on a screen; a user command input unit for receiving a user input of a multi-view mode start command; and a control unit for, when the multi-view mode start command is received, displaying second image content by generating a sub-screen in the screen, and when the second image content displayed in the sub-screen is selected, controlling the signal processing unit and the display unit to operate in a multi-view mode in which a plurality of content views are displayed by combining an image frame of the first image content and an image frame of the second image content.

Claims

1. A display apparatus comprising:

a signal processing unit for processing a first content and a second content;

a display screen for displaying the first content and the second content;

a user command input unit for inputting a multi-view mode start command to operate the display apparatus in a multi-view mode; and

a control unit operable to enable the second content to be selected in a sub-screen of the display screen while the first content is being viewed, and after the second content is selected via the sub-screen, the control unit is operable in the multi-view mode to display the first content to appear over a full area of the display screen while concurrently displaying the second content to appear over the same full area of the display screen.

2. The display apparatus of claim 1, wherein the second content displayed in the sub-screen can be selected from a plurality of sources including an external media player.

3. The display apparatus of claim 1, wherein the sub-screen is generated in the display screen as Picture in Picture (PIP).

4. The display apparatus of claim 1, wherein, when the multi-view mode start command is input, two sub-screens are generated in the display screen to enable the first content and the second content to be individually selected.

5. The display apparatus of claim 1, wherein the sub-screen is generated in the display screen as Picture by Picture (PBP).

6. The display apparatus of claim 1, wherein, in the multi-view mode, the first content and the second content are concurrently displayed on the display screen by combining image frames of the first content and the second content.

7. The display apparatus of claim 6, wherein, when a content change command for the sub-screen is input while the sub-screen displays the second content, the control unit controls the signal processing unit and the display unit to change a channel of the second content displayed in the sub-screen.

8. The display apparatus of claim 6, further comprising:

a synchronization signal generation unit for generating synchronization signals which synchronize glass apparatuses according to a display timing of an image frame of the first content and an image frame of the second content, and sending the generated synchronization signals to the glass apparatuses,

wherein the control unit controls the signal processing unit and the display unit to alternately display an image frame of the first content and an image frame of the second content, on a frame basis to correspond to the synchronization signals.

9. The display apparatus of claim 5, wherein, when a multi-view mode end command is input, the control unit controls the signal processing unit and the display unit to close the multi-view mode and to enter a screen mode which displays the first content in a main screen and displays the second content in a sub-screen.

10. The display apparatus of claim 9, wherein the control unit controls the signal processing unit and the display unit to remove the sub-screen when the first content displayed in the main screen is selected in the changed screen mode, and to display the second content in the main screen and to remove the sub-screen when the second content displayed in the sub-screen is selected.

11. The display apparatus of claim 1, wherein the number of the sub-screens varies according to a type of the multi-view.

12. A method for providing a multi-view mode on a display apparatus, the method comprising:

displaying a first content on a display screen;

when a multi-view mode start command is input, generating a sub-screen in the display screen;

enabling a second content to be selected via the sub-screen from a plurality of sources; and

when the second content displayed in the sub-screen is selected, operating in a multi-view mode which displays the first content to appear over a full area of the display screen while concurrently displaying the second content to appear over the same full area of the display screen.

13. The method of claim 12, wherein the plurality of sources from which the second content is selectable include an external media player.

14. The method of claim 12, wherein the sub-screen is generated in the screen as Picture in Picture (PIP).

15. The method of claim 12, wherein the sub-screen is generated in the screen as Picture by Picture (PBP).

16. The method of claim 12, wherein, in the multi-view mode, the first content and the second content are concurrently displayed on the display screen by combining an image frame of the first content and an image frame of the second content.

17. The method of claim 12, wherein the operating operation comprises:

when a content change command for the sub-screen is input while the sub-screen displays the second content, changing the second content displayed in the sub-screen.

18. The method of claim 17, further comprising:

generating a synchronization signal which synchronizes an eye glasses apparatus according to a display timing of an image frame of the first content and an image frame of the second content, and sending the generated synchronization signal to the eye glasses apparatus,

wherein the operating operation alternately combines and displays the image frame of the first content and the image frame of the second content, on a frame basis to correspond to the synchronization signal.

19. The method of claim 12, further comprising:

when a multi-view mode end command is input, closing the multi-view mode and entering a screen mode which displays the first content in a main screen and displays the second content in the sub-screen.

20. The method of claim 19, further comprising:

removing the sub-screen when the first content displayed in the main screen is selected in the mode entering operation, and displaying the second content in the main screen and removing the sub-screen when the second content displayed in the sub-screen is selected.

21. The method of claim 12, wherein the number of the sub-screens varies according to a type of the multi-view.
