Display system, display apparatus and method for controlling the same

1. A display system comprising:

a display apparatus configured to display a first image;

an image providing apparatus configured to provide a second image based on receiving a control signal for controlling the image providing apparatus;

a first remote control configured to transmit the control signal for controlling the image providing apparatus; and

a second remote control,

wherein the display apparatus is further configured to:

receive the control signal for controlling the image providing apparatus, from the first remote control, and the second image, responsive to the control signal, from the image providing apparatus,

display the received second image,

identify a predetermined object in the second image by comparing the first image with the second image,

obtain apparatus information of the image providing apparatus based on the control signal received from the first remote control and a change status of the identified predetermined object, and

transmit the apparatus information to the second remote control, and

wherein the apparatus information comprises a control code set corresponding to the image providing apparatus.

2. A display apparatus comprising:

a communicator;

a display; and

a processor configured to:

control the display to display a first image received from an image providing apparatus,

receive, through the communicator, a control signal for controlling the image providing apparatus from a first remote control, and a second image, responsive to the control signal, from the image providing apparatus, and

control the display to display the second image,

identify a predetermined object in the second image by comparing the first image with the second image,

obtain apparatus information of the image providing apparatus based on the control signal received from the first remote control and a change status of the identified predetermined object, and

control the communicator to transmit the apparatus information to a second remote control,

wherein the apparatus information comprises a control code set corresponding to the image providing apparatus.

3. The display apparatus as claimed in claim 2 , wherein the processor is further configured to:

compare the first image received by the communicator from the image providing apparatus before the communicator receives the control signal with the second image received by the communicator from the image providing apparatus after the communicator receives the control signal to identify a control command corresponding to the control signal, and

obtain the apparatus information of the image providing apparatus based on the identified control command and the control signal.

4. The display apparatus as claimed in claim 3 , wherein the processor is further configured to control the communicator to transmit the identified control command and the control signal to a server, and receive the apparatus information of the image providing apparatus from the server.

5. The display apparatus as claimed in claim 2 , wherein the processor is further configured to obtain a logo in the second image provided by the image providing apparatus to obtain the apparatus information of the image providing apparatus.

6. The display apparatus as claimed in claim 2 , wherein the processor is further configured to, based on sensing a connection with the image providing apparatus and the communicator receiving the control signal for controlling the image providing apparatus, obtain the apparatus information of the image providing apparatus.

7. The display apparatus as claimed in claim 2 , wherein the processor is further configured to update a source name of the image providing apparatus based on the obtained apparatus information.

8. The display apparatus as claimed in claim 7 , wherein the processor is further configured to control the display to display a source list comprising the updated source name.

9. A method for controlling a display apparatus, the method comprising:

displaying a first image received from an image providing apparatus;

receiving, by the display apparatus, a control signal for controlling the image providing apparatus, from a first remote control, and a second image, responsive to the control signal, from the image providing apparatus;

displaying the received second image;

identifying a predetermined object in the second image by comparing the first image with the second image;

obtaining apparatus information of the image providing apparatus based on the control signal received from the first remote control and a change status of the identified predetermined object; and

transmitting the apparatus information to a second remote control,

wherein the apparatus information comprises a control code set corresponding to the image providing apparatus.

10. The method as claimed in claim 9 , wherein the obtaining the apparatus information of the image providing apparatus comprises:

comparing the first image received before receiving the control signal with the second image received after receiving the control signal to identify a control command corresponding to the control signal, and

obtaining the apparatus information of the image providing apparatus based on the identified control command and the control signal.

11. The method as claimed in claim 10 , wherein the obtaining the apparatus information of the image providing apparatus comprises:

transmitting the identified control command and the control signal to a server, and

receiving the apparatus information of the image providing apparatus from the server.

12. The method as claimed in claim 9 , wherein the obtaining the apparatus information of the image providing apparatus comprises obtaining a logo in the second image provided from the image providing apparatus to obtain the apparatus information of the image providing apparatus.

13. The method as claimed in claim 9 , wherein the obtaining the apparatus information of the image providing apparatus comprises, based on discovering a connection with the image providing apparatus and receiving the control signal for controlling the image providing apparatus, obtaining the apparatus information of the image providing apparatus.

14. The method as claimed in claim 9 , further comprising updating a source name of the image providing apparatus using the obtained apparatus information.

15. The method as claimed in claim 14 , further comprising displaying a source list comprising the updated source name.
