Abstract

A display apparatus includes a display, a communicator configured to communicate with a server, and a processor. The processor is configured to control the communicator to transmit graphic data to be displayed on the display to the server, control the communicator to receive from the server video data into which the graphic data is converted, and process and display the received video data on the display.

First claim

What is claimed is:

1. A display apparatus comprising:
a display;
a communicator configured to communicate with a server; and
a processor, by which video data having a first resolution is processible, and which is configured to:
receive content including graphic data,
identify the graphic data including first graphic data and second graphic data, wherein the first graphic data has the first resolution, the second graphic data has a second resolution, the first resolution is greater than the second resolution, and the first graphic data having the first resolution is not processible by the processor,
in response to the identifying the first graphic data having the first resolution included in the identified graphic data, control the communicator to transmit the first graphic data to the server, and, receive the video data, wherein the received video data corresponds to the transmitted first graphic data which has been converted into the video data by the server,
process the received video data, and
display the processed video data on the display.

2. The display apparatus according to claim 1 , wherein the second graphic data is greater in a degree of change in an image than the first graphic data.

3. The display apparatus according to claim 1 , wherein the processor is further configured to:
identify among the graphic data a part of the graphic data that has a greater degree of change in an image than a remaining part of the graphic data, and
divide the graphic data so that the second graphic data includes the part of the graphic data that has the greater degree of change in the image, and the first graphic data includes the remaining part of the graphic data.

4. The display apparatus according to claim 1 , wherein the processor is further configured to process the second graphic data without converting the second graphic data into video data.

5. The display apparatus according to claim 1 , wherein the processor is further configured to:
obtain synthesized data by synthesizing the video data with the second graphic data, and
display the video data and the second graphic data as the synthesized data.

6. The display apparatus according to claim 1 , wherein the video data obtained by converting the first graphic data by the server is a first video data, and
the processor is further configured to:
directly process a second video data received via the communicator from an external device,
obtain synthesized data by synthesizing the first video data received from the server with the directly processed second video data, and
display the second graphic data and the synthesized data on the display.

7. The display apparatus according to claim 1 , wherein the processor comprises a graphics processor configured to directly process and display the second graphic data in correspondence with the second resolution of the second graphic data processible by the graphics processor.

8. The display apparatus according to claim 7 , wherein the processor is further configured to:
obtain synthesized data by synthesizing the video data with the second graphic data directly processed by the graphics processor, and
display the video data and the second graphic data as the synthesized data.

9. The display apparatus according to claim 1 , wherein the processor is further configured to convert the graphic data into the video data by performing a color space conversion.

10. A display apparatus comprising:
a display; and
a processor, by which video data having a first resolution is processible, and which is configured to:
receive content including graphic data to be displayed on the display,
identify the graphic data including first graphic data and second graphic data, wherein the first graphic data has the first resolution, the second graphic data has a second resolution, the first resolution is greater than the second resolution, and the first graphic data having the first resolution is not processible by the processor,
in response to the identifying the first graphic data having the first resolution included in the identified graphic data, convert the first graphic data into the video data having the first resolution, wherein the video data corresponds to the first graphic data, and
process and display the video data having the first resolution on the display.

11. A control method of a display apparatus, the control method comprising:
receiving content including graphic data;
identifying the graphic data including first graphic data and second graphic data, wherein the first graphic data has a first resolution, the second graphic data has a second resolution, the first resolution is greater than the second resolution, video data having the first resolution is processible by a processor of the display apparatus, and the first graphic data having the first resolution is not processible by the processor,
in response to the identifying the first graphic data having the first resolution included in the identified graphic data, transmitting the first graphic data to a server, and receiving the video data, wherein the received video data corresponds to the transmitted first graphic data which has been converted into the video data by the server;
processing the received video data; and
displaying the processed video data.

12. The control method according to claim 11 , wherein the second graphic data is greater in a degree of change in an image than the first graphic data.

13. The control method according to claim 11 , wherein the identifying the content including the first graphic data and the second graphic data further comprises:
identifying among the graphic data a part of the graphic data that has a greater degree of change in an image than a remaining part of the graphic data; and
dividing the graphic data so that the second graphic data includes the part of the graphic data that has the greater degree of change in the image, and the first graphic data includes the remaining part of the graphic data.

14. The control method according to claim 11 , wherein the processing further comprises:
processing the second graphic data without converting the second graphic data into video data.

15. The control method according to claim 11 , further comprising:
obtaining synthesized data by synthesizing the video data received from the server with the second graphic data; and
displaying the video data and the second graphic data as the synthesized data.

16. The control method according to claim 11 , wherein the video data obtained by converting the first graphic data by the server is a first video data, and
the control method further comprises:
obtaining synthesized data by synthesizing the first video data received from the server with the directly processed second video data; and
displaying the second graphic data and the synthesized data.

17. The control method according to claim 11 , wherein the processing further comprises:
directly processing the second graphic data, in correspondence with the second resolution processible by a graphics processor of the display apparatus.

18. The control method according to claim 17 , wherein the directly processing further comprises:
obtaining synthesized data by synthesizing the video data with the second graphic data directly processed by the graphics processor, and
displaying the video data and the second graphic data as the synthesized data.

19. The control method according to claim 11 , wherein the graphic data is converted into the video data by performing a color space co
