Abstract

A method is described for controlling a television. While receiving and displaying a broadcast signal on a screen of the television, the television receives a first signal from a remote controller and displays a control icon corresponding to the remote controller on the screen. The screen is partitioned into a first and second partition, the first partition being a broadcast signal display region continuing to display the broadcast signal, and the second partition being a television control region that includes television control icons and/or subregions. A second signal is wirelessly received from the remote controller, the second signal representing a movement of the remote controller. The control icon is moved across the screen of the television in response to the movement of the remote controller. A channel list is displayed based on whether the second sign is recognized within or out of the second partition.

Claims

1. A digital broadcast receiver controlled by a motion remote controller, the digital broadcast receiver comprising:

an infrared (IR) module configured to receive an IR signal from the motion remote controller;

a controller configured to change a power-off state of the broadcast receiver into a power-on state of the broadcast receiver based on the received IR signal; and

a radio frequency (RF) module configured to receive an RF signal from the motion remote controller,

wherein the controller is further configured to;

display a screen remote controller in a predetermined region on a screen and during displaying of a broadcast program on the screen, wherein the screen remote controller comprises a first, second and third control regions, the first control region corresponding to at least one number used to change at least one channel of the broadcast receiver, the second control region corresponding to at least one special character used to identify a major channel number with a minor channel number and the third control region corresponding to a function item for returning to a previous channel,

move a position of a pointer within the screen remote controller based on movement information of the motion remote controller included in the RF signal, and

change a current channel into another channel in response to the pointer being located at a specific control region among the first, second and third control regions within the screen remote controller and a specific button signal being received from the motion remote controller.

2. The digital broadcast receiver of claim 1, wherein the movement information of the motion remote controller further identifies direction information and speed information of a movement of the motion remote controller.

3. The digital broadcast receiver of claim 1, further comprising:

a memory configured to store data on a frequency band for pairing the digital broadcast receiver with the motion remote controller.

4. The digital broadcast receiver of claim 3, wherein the screen remote controller corresponds to image data pre-stored in the memory.

5. The digital broadcast receiver of claim 1, wherein a location of the pointer within the screen remote controller is further configured to be controlled by a touch sensor included in the motion remote controller as well as a motion sensor included in the motion remote controller.

6. The digital broadcast receiver of claim 5, wherein the location of the pointer is changed depending on the movement information from the touch sensor as well as the motion sensor.

7. The digital broadcast receiver of claim 6, wherein the controller is further configured to enlarge or reduce a size of the screen remote controller displayed on the screen in response to the motion remote controller being moved back and forth.

15. The digital broadcast receiver of claim 1, wherein the controller is further configured to stop displaying the screen remote controller after a predetermined period of time.

16. The digital broadcast receiver of claim 1, wherein display coordinates of the screen remote controller are controlled by the motion information of the motion remote controller.

17. The digital broadcast receiver of claim 1, wherein the controller is further configured to display at least one control region on the screen for performing another function different than the changing at least one channel of the broadcast receiver.

18. The digital broadcast receiver of claim 17, wherein the at least one control region includes a guide control region for providing a broadcast guide in response to the position of the pointer being located within the guide control region.

19. The digital broadcast receiver of claim 17, wherein the controller is further configured to display the at least one control region above the first control region corresponding to at least number used to change at least one channel of the broadcast receiver.

20. The digital broadcast receiver of claim 1, wherein

wherein the first control region includes the numbers 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0;

the special character of the second control region includes the dash character “

-”

; and

the third control region corresponding to the function item for returning to the previous channel includes information for returning to the previous channel.

21. The digital broadcast receiver of claim 1, wherein functions corresponding to the first control region, the second control region and the third control are absent from the motion remote controller.

22. The digital broadcast receiver of claim 1, wherein a number of sub-regions on the screen remote controller for executing functions on the digital broadcast receiver is greater than a number of sub-regions on the motion remote controller for controlling functions on the digital broadcast receiver.

8. A method for processing data in a digital broadcast receiver, the method comprising:

receiving an infrared (IR) signal from a motion remote controller;

changing a power-off state of the broadcast receiver into a power-on state based on the received IR signal;

receiving a radio frequency (RF) signal from the motion remote controller;

displaying a screen remote controller in a predetermined region of a screen and during displaying of a broadcast program, wherein the screen remote controller comprises a first, second and third control regions, the first control region corresponding to at least one number used to change at least one channel of the broadcast receiver, the second control region corresponding to at least one special character used to identify a major channel number with a minor channel number and the third control region corresponding to a function item for returning to a previous channel;

moving a position of a pointer within the screen remote controller based on movement information of the motion remote controller included in the RF signal; and

changing a current channel into another channel in response to the pointer being located at a specific control region among the first, second and third control regions within the screen remote controller and a specific button signal being received from the motion remote controller.

9. The method of claim 8, wherein the movement information of the motion remote controller further identifies direction information and speed information of a movement of the motion remote controller.

10. The method of claim 8, further comprising:

storing data on a frequency band into a memory for pairing the digital broadcast receiver with the motion remote controller.

11. The method of claim 10, wherein the screen remote controller corresponds to image data pre-stored in the memory.

12. The method of claim 8, wherein a location of the pointer within the screen remote controller is further configured to be controlled by a touch sensor included in the motion remote controller as well as a motion sensor included in the motion remote controller.

13. The method of claim 12, wherein the location of the pointer is changed depending on the movement information from the touch sensor as well as the motion sensor.

14. The method of claim 13, further comprising:

enlarging or reducing a size of the screen remote controller in response to the motion remote controller being moved back and forth.
