Abstract

A display apparatus, a source apparatus, and methods of providing content are provided. The display apparatus includes: a receiver which receives content data; a storage which stores frame size information corresponding to a content type; a detector which detects the content type of the content data; a video processor which forms a content frame having a frame size corresponding to the detected content type by using the frame size information stored in the storage; and a display which displays the content frame formed by the video processor.

First claim

What is claimed is:

1. A source device for providing a content to a display device comprising:
an interface; and
a controller configured to:
receive feature information of the display device from the display device through the interface, the feature information comprising information related to a screen size of the display device,
adjust a frame size of a content frame based on the screen size of the display device and a type of the content, and
control the interface to transmit content data including the content frame of the adjusted frame size to the display device,

wherein the content type comprises at least a moving picture content type, and
wherein the adjusted frame size is larger than the screen size of the display if the content type is the moving picture content type.

2. The source device according to claim 1 , further comprising:
a storage storing frame size adjustment information for each content type,
wherein the controller is configured to:
obtain frame adjustment information corresponding to the content type of the content from the storage, and
adjust the frame size of the content based on the frame adjustment information and the screen size of the display device.

3. The source device according to claim 1 , wherein based on identifying that adjusting the frame size by the display device is impossible, the controller is configured to adjust the frame size of the content frame based on the screen size of the display device and the content type.

4. The source device according to claim 1 , wherein based on identifying that adjusting the frame size by the display device is possible based on the feature information, the controller is configured to control information on the content type of the content to be transmitted to the display device.

5. The source device according to claim 4 , wherein based on identifying that the feature information comprises frame size information related to the content type, the controller is configured to identify that the display device is capable of adjusting a frame size.

6. The source device according to claim 1 , wherein the interface is an HDMI interface, and
wherein the controller is configured to control the interface to transmit the content data comprising AVI infoframe which includes information on the content type.

7. The source device according to claim 1 , wherein the controller is configured to control the interface to transmit a message indicating that the frame size of the content frame is adjusted to the display device through the interface.

8. A control method of a source device for providing a content to a display device via an interface, the control method comprising:
receiving feature information of the display device from the display device, the feature information comprising information related to a screen size of the display device,
adjusting a frame size of a content frame based on the screen size of the display device and a type of the content, and
transmitting content data including the content frame of the adjusted frame size to the display device,
wherein the content type comprises at least a moving picture content type, and
wherein the adjusted frame size is larger than the screen size of the display if the content type is the moving picture content type.

9. The control method according to claim 8 , wherein the adjusting the frame size of the content frame comprises:
obtaining frame adjustment information corresponding to the content type of the content from a pre-stored frame size adjustment information, and
adjusting the frame size of the content based on the frame adjustment information and the screen size of the display device.

10. The control method according to claim 8 , wherein the adjusting the frame size of the content frame comprises:
based on identifying that that adjusting the frame size by the display device is impossible, adjusting the frame size of the content frame based on the screen size of the display device and the content type.

11. The control method according to claim 8 , further comprising:
based on identifying that adjusting the frame size by the display device is possible based on the feature information, transmitting information on the content type of the content to the display device.

12. The control method according to claim 11 , further comprising:
based on identifying that the feature information comprises frame size information related to the content type, identifying that the display device is capable of adjusting a frame size.

13. The control method according to claim 8 , wherein the interface is an HDMI interface, and
wherein the transmitting the content data transmitted to the display device comprises AVI infoframe which includes information on the content type.

14. The control method according to claim 8 , further comprising:
transmitting a message indicating that the frame size of the content frame is adjusted to the display device through the interface.

15. A non-transitory computer readable recording medium having embodied thereon a program, which when executed by a processor of a source device causes the source device to execute a method of providing a content to a display device from the source device via an interface, the method including:
receiving feature information of the display device from the display device, the feature information comprising information related to a screen size of the display device,
adjusting a frame size of a content frame based on the screen size of the display device and a type of the content, and
transmitting content data including the content frame of the adjusted frame size to the display device,
wherein the content type comprises at least a moving picture content type, and
wherein the adjusted frame size is larger than the screen size of the display if the content type is the moving picture content type.

16. The non-transitory computer readable recording medium according to claim 15 , wherein the adjusting the frame size of the content frame comprises:
obtaining frame adjustment information corresponding to the content type of the content from a pre-stored frame size adjustment information, and
adjusting the frame size of the content based on the frame adjustment information and the screen size of the display device.

17. The non-transitory computer readable recording medium according to claim 15 , wherein the adjusting the frame size of the content frame comprises:
based on identifying that that adjusting the frame size by the display device is impossible, adjusting the frame size of the content frame based on the screen size of the display device and the content type.

18. The non-transitory computer readable recording medium according to claim 15 , further comprising:
based on identifying that adjusting the frame size by the display device is possible based on the feature information, transmitting information on the content type of the content to the display device.

19. The non-transitory computer readable recording medium according to claim 18 , further comprising:
based on identifying that the feature information comprising frame size information related to the content type, identifying that the display device is capable of adjusting a frame size.

20. The control method according to claim 15 , wherein the interface is an HDMI interface, and
wherein the transmitting the content data transmitted to the display device comprises AVI infoframe which includes information on the content type.
