Abstract

An image display apparatus and a method for providing an Xlet of the image display apparatus, are provided. The image display apparatus operated by a remote controller having a plurality of function keys, the image display apparatus comprises: an Xlet unit which performs Xlet included in a data broadcast signal; and a display unit which displays the preoccupied state of the plurality of function keys by the performed Xlet. Accordingly, a user may easily recognize the performed state of the Xlet.

Claims

1. An image display apparatus operated by a remote controller having a plurality of function keys, the image display apparatus comprising:

an Xlet unit which performs an Xlet included in a data broadcast signal; and

a display unit which displays a state of a plurality of function keys preoccupied by the performed Xlet among the plurality of function keys,

wherein the function keys which are preoccupied by the Xlet are operable only for the Xlet.

2. The image display apparatus as claimed in claim 1, further comprising:

a control unit which controls the Xlet unit to perform an operation corresponding to an input signal input from the remote controller, if the input signal corresponds to a selection of one of the function keys preoccupied by the Xlet.

3. The image display apparatus as claimed in claim 1, wherein the display unit displays a plurality of function keys, which excludes the plurality of function keys preoccupied by the performed Xlet.

4. The image display apparatus as claimed in claim 2, wherein the control unit controls the display unit to display the Xlet performed by the Xlet unit, if an input signal corresponds to the selection of the at least one of the function keys preoccupied by the Xlet, which has been set to perform the Xlet.

5. The image display apparatus as claimed in claim 2, wherein the control unit controls the display unit to display a message informing a user that the Xlet is being performed, if an input signal corresponds to the selection of one of the function keys preoccupied by the Xlet, which has not been set to perform the Xlet.

6. The image display apparatus as claimed in claim 2, wherein the control unit controls the display unit to display the Xlet performed by the Xlet unit, if a visual change of the Xlet is generated by the Xlet unit.

7. The image display apparatus as claimed in claim 2, wherein the control unit controls the display unit to display a message informing a user that the Xlet is being performed, if a visual change of the Xlet is not generated by the Xlet unit.

8. The image display apparatus as claimed in claim 6, further comprising:

a screen managing unit which changes a screen in response to a request of the Xlet unit,

wherein the control unit determines that a visual change of the Xlet is generated, if the screen managing unit calls for a function for use when the screen is changed.

17. The image display apparatus according to claim 1, wherein the image display apparatus is located separately from the remote controller.

18. The image display apparatus according to claim 1, wherein the Xlet is one of an automatic start type and a manual start type.

19. The image display apparatus according to claim 1, wherein the Xlet unit manages Xlets received at the image display apparatus and contains information on the Xlets.

20. The image display apparatus according to claim 1, wherein the display unit displays the state of the plurality of functions keys of the remote controller for a predetermined period of time while a general broadcast is viewed on the image display apparatus.

9. A method for providing an Xlet of an image display apparatus operated by a remote controller having a plurality of function keys, the method comprising:

performing the Xlet included in a data broadcast signal; and

displaying a state of a plurality of function keys preoccupied by the performed Xlet among the plurality of function keys,

wherein the function keys which are preoccupied by the Xlet are operable only for the Xlet.

10. The method as claimed in claim 9, the method further comprising:

controlling the Xlet to perform an operation corresponding to an input signal input from the remote controller, if the input signal corresponds to a selection of one of the function keys preoccupied by the Xlet.

11. The method as claimed in claim 9, wherein the state of the plurality of function keys preoccupied by the performed Xlet is displayed by only displaying a plurality of function keys not preoccupied by the performed Xlet.

12. The method as claimed in claim 10, wherein in the performing the operation corresponding to the input signal, the performed Xlet is displayed if the input signal corresponds to the selection of one of the function keys preoccupied by the Xlet, which has been set to perform the Xlet.

13. The method as claimed in claim 10, wherein in the performing the operation corresponding to the input signal, a message informing a user that the Xlet is being performed is displayed if the input signal corresponds to the selection of one of the function keys preoccupied by the Xlet, which has not been set to perform the Xlet.

14. The method as claimed in claim 10, wherein in the performing the operation corresponding to the input signal, the performed Xlet is displayed if a visual change of the Xlet is generated.

15. The method as claimed in claim 10, wherein in the performing the operation corresponding to the input signal, a message informing a user that the Xlet is being performed is displayed if a visual change of the Xlet is not generated.

16. The method as claimed in claim 14, the method further comprising:

calling for a function for use when a screen is changed,

wherein, in performing the operation corresponding to the input signal, it is determined that the visual change of the Xlet is generated, if the function for use when the screen is changed, is called for.
