Abstract

A method for an electronic device configured to control a display device by using a watermark is provided. The method includes receiving a captured image of the display device from a remote control device, extracting a watermark from the captured image, acquiring a menu for the display device based on the watermark, and transmitting the menu to the remote control device for controlling the display device.

Claims

1. A method for an electronic device configured to control a display device by using a watermark, the method comprising:

receiving, by the electronic device, a captured image of at least one display device from a remote control device;

extracting, by the electronic device, a watermark from the captured image;

acquiring, by the electronic device, a menu for controlling the display device based on the watermark; and

providing the menu from the electronic device to the remote control device,

wherein the extracting comprises;

extracting a plurality of watermarks, including the watermark, from the captured image; and

identifying the at least one device, including the display device, corresponding to the plurality of watermarks respectively,

wherein the providing the menu comprises providing a plurality of menus, including the menu, matched with the at least one device respectively to the remote control device, and

wherein the plurality of menus are displayed on a screen of the remote control device.

2. The method of claim 1, wherein the electronic device is a server.

3. The method of claim 1, wherein the acquiring the menu comprises:

determining a function of the display device based on the watermark;

retrieving function information related to the function; and

selecting the menu based on at least the function information.

4. The method of claim 1, wherein the menu includes a control command for controlling the remote control device, and

wherein the menu is used by the remote control device to control the display device.

5. The method of claim 1, wherein the captured image is generated by the remote control device photographing the display device.

6. The method of claim 5, wherein the display device is photographed by the remote control device when the remote control device is positioned toward the display device, and

wherein the captured image is generated by the remote control device based on the photographed display device.

7. The method of claim 5, wherein the captured image is generated by the remote control device in response to a predetermined gesture.

8. The method of claim 1, wherein the acquiring the menu further comprises:

determining whether the watermark is valid;

acquiring a device identifier (ID) of the display device matched with the watermark in response to the watermark being valid; and

acquiring a menu based on the device ID, wherein the menu is configured to control the display device.

9. The method of claim 1, further comprising:

determining that the display device is usable within a network;

generating the watermark for the display device;

acquiring function information related to a function of the display device; and

matching and registering a device identifier (ID) of the display device with the watermark and the function information.

10. The method of claim 1, wherein the menu is displayed on a screen of the remote control device and is edited based on an input on the remote control device.

11. The method of claim 1, wherein the captured image is generated by photographing an image displayed on the display device, and

wherein the image displayed on the display device includes the watermark rendered by the display device and video content rendered by the display device.

12. The method of claim 1, wherein the acquiring of the menu comprises:

receiving the menu from at least one of the display device, another device of a user, and a manufacturer server.

13. The method of claim 1, further comprising:

receiving a user input selecting one of the plurality of menus; and

sending at least one controlling command to a display device corresponding to a menu selected by the user input.

14. An electronic device configured to control a display device by using a watermark, the electronic device comprising:

a processor configured to extract a plurality of watermarks from a captured image that is received from a remote control device, identify at least one display device corresponding to the plurality of watermarks respectively,

acquire a plurality of menus for respectively controlling the at least one display device based on the plurality of watermarks, and

a communication interface configured to transmit the plurality of menus to the remote control device.

15. The electronic device of claim 14, wherein the electronic device is a server.

16. The electronic device of claim 14, wherein the captured image is generated by the remote control device in response to a predetermined gesture.

17. The electronic device of claim 14, wherein the processor is further configured to determine whether the plurality of watermarks are valid, and

wherein the plurality of menus are acquired in response to the plurality of watermarks being valid.

18. The electronic device of claim 14, wherein the processor is further configured to generate the plurality of watermarks of the at least one display device.

19. The electronic device of claim 14, further comprising:

a database configured to store matching information after matching a device identifier (ID) of the at least one display device, the plurality of watermarks, and function information regarding a function of the at least one display device.

20. A method for a remote control device configured to control a display device, the method comprising:

transmitting a captured image of at least one display device from the remote control device to an electronic device;

receiving, by the remote control device, a plurality of menus for controlling the at least one display device, respectively, from the electronic device; and

controlling, by the remote control device, the display device based on a user input selecting a menu among the plurality of menus,

wherein the captured image includes a plurality of watermarks of the at least one display device, and

wherein the plurality of watermarks are used in acquiring the plurality of menus for the electronic device to control the at least one display device respectively.
