Abstract

Disclosed are display apparatus, remote controller, a display system and a control method thereof. The display system includes a display apparatus and a remote controller for controlling the display apparatus. The display apparatus includes: a first communicating unit that communicates with the remote controller; and an image control unit that generates control item information for controlling a predetermined control item, transmits the generated control item information to the remote controller, and controls the control item according to a control signal received from the remote controller. The remote controller includes: a second communicating unit that receives the control item information from the display apparatus; a user selection unit for selection by a user; and a remote control unit that allocates a control function for controlling the control item to the user selection unit and outputs the control signal corresponding to the control function selected by the user to the display apparatus.

Claims

1. A remote controller for controlling an external display apparatus, comprising:

a communication unit that receives control item information for controlling control items of the external display apparatus, from the external display apparatus;

a user selection unit that receives input from a user; and

a controller unit that allocates a control function for controlling one of the control items to the user selection unit based on the control item information and outputs a control signal corresponding to the control function selected by the user, to the external display apparatus.

2. The remote controller according to claim 1, wherein the communication unit conducts RF communication with the external display apparatus.

3. The remote controller according to claim 1, wherein the control item information comprises a key code for controlling the one of the control items and the control signal is generated based on the key code.

4. The remote controller according to claim 1, wherein the user selection unit comprises a touch panel, and the controller unit displays an image indicating the control function on the touch panel.

5. The remote controller according to claim 1, wherein the user selection unit comprises a plurality of buttons and the control function is one of a plurality of control functions,

the remote controller further comprising a display unit which displays the plurality of control functions corresponding to the plurality of buttons.

6. The remote controller according to claim 1, wherein the control function is one of a plurality of control functions and the user selection unit comprises a plurality of buttons, and the plurality of buttons comprises light-emitting elements that emit lights if the plurality of control functions is allocated to the plurality of buttons.

7. The remote controller according to claim 1, wherein, upon receiving the control item information corresponding to a mode from the external display apparatus, the controller unit allocates the control function to change a channel of a broadcasting signal and another control function for adjusting a sound of the external display apparatus, to the user selection unit.

8. A display apparatus controlled by an external a remote controller, comprising:

a communication unit that communicates with the remote controller; and

a controller unit that generates control item information on a control function for controlling a control item, transmits the generated control item information to the external remote controller, and controls the control item according to a control signal corresponding to the control function received from the external remote controller.

9. The display apparatus according to claim 8, wherein the control item information comprises a key code for controlling the control item.

10. The display apparatus according to claim 8, wherein the controller unit transmits user interface (UI) information for controlling the control item, to the external remote controller.

11. The display apparatus according to claim 8, further comprising a broadcasting receiving unit that receives a broadcasting signal and a power supply that turns on or off power supplied to the broadcasting receiving unit,

wherein, if the power supply turns on the power, the controller unit transmits control item information for a mode for changing a channel of the broadcasting signal and sound of the display apparatus, to the external remote controller.

12. The display apparatus according to claim 8, wherein, if an external device is connected to the display apparatus, the controller unit generates control item information for controlling the external device, transmits the generated control item information for controlling the external device to the external remote controller, and controls the external device according to a control signal generated based on the control item information for controlling the external device, received from the external remote controller.

13. A display system including a display apparatus and a remote controller for controlling the display apparatus, the display apparatus comprising:

a first communication unit that communicates with the remote controller; and

an image control unit that generates control item information for controlling a control item, transmits the generated control item information to the remote controller, and controls the control item according to a control signal received from the remote controller, and the remote controller comprising;

a second communication unit that receives the control item information from the display apparatus;

a user selection unit which receives an input of a user; and

a remote control unit that allocates a control function for controlling the control item to the user selection unit and outputs the control signal corresponding to the control function selected by the user, to the display apparatus.

14. The display system according to claim 13, wherein the first communication unit conducts RF communication with the second communication unit.

15. The display system according to claim 13, wherein the control item information comprises a key code for controlling the control item and the control signal is generated based on the key code.

16. The display system according to claim 13, wherein the display apparatus further comprises a broadcasting receiving unit for receiving a broadcasting signal and a power supply unit that turns on or off power supplied to the broadcasting receiving unit,

wherein, if the power supply unit turns on the power, the image control unit transmits the control item information for a mode for changing channel of the broadcasting signal and a sound of the display apparatus, to the remote controller, and

wherein the remote control unit allocates a control function to change the channel of the broadcasting signal and the sound of the display apparatus, to the user selection unit.

17. A method of controlling a display system including a display apparatus and a remote controller having a user selection unit, the method comprising:

generating control item information for controlling a control item, and transmitting the generated control item information to the remote controller;

allocating a control function for controlling the control item to the user selection unit based on the control item information;

outputting a control signal corresponding to the control function selected by a user, to the display apparatus; and

controlling the control item according to the control signal.

18. The method according to claim 17, wherein the display apparatus conducts RF communication with the remote controller.

19. The method according to claim 17, wherein the control item information comprises a key code for controlling the control item and the control signal is generated based on the key code.
