Mobile terminal, image display device and user interface provision method using the same

1. A method for sharing data with a mobile terminal in an image display device, the method comprising:

receiving a broadcast signal including audio and video data;

connecting to the mobile terminal via a wireless network interface;

controlling the wireless network interface to transmit data to the mobile terminal wirelessly connected to the image display device;

controlling the wireless network interface to receive screen information from the mobile terminal wirelessly connected to the image display device; and

displaying a mirroring image based on the screen information received from the mobile terminal in a first region while displaying the video data included in the broadcast signal in a second region, wherein the mirroring image corresponds to a current screen displayed on the mobile terminal, further the video data is received via a tuner while the screen information is received via the wireless network interface different from the tuner.

2. The method of claim 1 , wherein the transmitted data includes information which indicates a screen posture direction of the image display device.

3. The method of claim 2 , wherein the screen information with margins is received from the mobile terminal if a screen posture direction of the mobile terminal is different from the screen posture direction of the image display device.

4. The method of claim 3 , wherein the screen information without the margins is received from the mobile terminal if the screen posture direction of the mobile terminal is same as the screen posture direction of the image display device.

5. The method of claim 1 , further comprising:

receiving a user command for controlling the mobile terminal from a wireless remote controller; and

controlling the wireless network interface to transmit the received user command to the mobile terminal.

6. The method of claim 5 , further comprising:

generating coordinate information of a cursor controlled by the wireless remote controller;

comparing boundary coordinate information of the first region and the second region with the generated coordinate information of the cursor; and

determining which region is to be controlled by the wireless remote controller.

7. The method of claim 1 , further comprising arranging the first region at the foremost side of the display and highlighting the first region in order to notify a user that an event has occurred in the mobile terminal.

8. The method of claim 1 , further comprising:

providing a user interface for changing at least one of a location or a size of each of the first and second regions.

9. The method of claim 1 , wherein the wireless network interface performs based on Wi-Fi, Bluetooth or Zigbee.

10. A digital broadcast terminal for sharing data with a mobile terminal, the digital broadcast terminal comprising:

a tuner configured to receive a broadcast signal including audio and video data;

a wireless network interface configured to transmit data to the mobile terminal wirelessly connected to the digital broadcast terminal and receive screen information from the mobile terminal wirelessly connected to the digital broadcast terminal; and

a signal processor configured to output a mirroring image based on the screen information received from the mobile terminal while outputting the video data included in the broadcast signal received via the tuner, wherein the mirroring image corresponds to a current screen displayed on the mobile terminal.

11. The digital broadcast terminal of claim 10 , further comprising:

a controller configured to receive a user command for controlling the mobile terminal from a wireless remote controller, and control the wireless network interface to transmit the received user command to the mobile terminal.

12. The digital broadcast terminal of claim 11 , wherein the controller is further configured to:

generate coordinate information of a cursor controlled by the wireless remote controller,

compare boundary coordinate information of the first region and the second region with the generated coordinate information of the cursor, and

determine which region is to be controlled by the wireless remote controller.

13. The digital broadcast terminal of claim 12 , wherein the controller is further configured to provide a user interface for changing at least one of a location or a size of each of the first and second regions.

14. The digital broadcast terminal of claim 11 , wherein the wireless network interface performs based on Wi-Fi, Bluetooth or Zigbee.

15. An image display device for sharing data with a mobile terminal, the image display device comprising:

an A/V input unit configured to receive a broadcast signal including audio and video data;

a wireless network interface configured to connect to the mobile terminal; and

a controller configured to:

control the wireless network interface to transmit data to the mobile terminal wirelessly connected to the image display device, wherein the transmitted data includes information which indicates a screen posture direction of the image display device;

control the wireless network interface to receive screen information from the mobile terminal wirelessly connected to the image display device; and

display a mirroring image based on the screen information received from the mobile terminal in a first region while displaying the video data included in the broadcast signal in a second region, wherein the mirroring image corresponds to a current screen displayed on the mobile terminal, further the video data is received via the A/V input unit while the screen information is received via the wireless network interface different from the A/V input unit.

16. The image display device of claim 15 , wherein the screen information with margins is received from the mobile terminal if a screen posture direction of the mobile terminal is different from the screen posture direction of the image display device.

17. The image display device of claim 16 , wherein the screen information without the margins is received from the mobile terminal if the screen posture direction of the mobile terminal is same as the screen posture direction of the image display device.

18. The image display device of claim 15 , wherein the controller is further configured to control the wireless network interface to transmit the received user command to the mobile terminal in response to receiving a user command for controlling the mobile terminal from a wireless remote controller.

19. The image display device of claim 18 , wherein the controller is further configured to:

generate coordinate information of a cursor controlled by the wireless remote controller;

compare boundary coordinate information of the first region and the second region with the generated coordinate information of the cursor; and

determine which region is to be controlled by the wireless remote controller.

20. The image display device of claim 15 , wherein the controller is further configured to arrange the first region at the foremost side of the display and highlight the first region in order to notify a user that an event has occurred in the mobile terminal.

21. The image display device of claim 15 , wherein the controller is further configured to provide a user interface for changing at least one of a location or a size of each of the first and second regions.
