Abstract

An apparatus and method for providing an image-based remote user interface (UI) using a web browser are provided. A server includes an user interface (UI) application which provides a dynamic image; a server communication module which, if the dynamic image is updated, transmits an image update event for the updated dynamic image; and a hypertext transfer protocol (HTTP) server which receives a request corresponding to the image update event and transmits the updated dynamic image in response to the received request. The method includes if an image in a remote user interface (UI) is updated, transmitting an image update event for the updated image; receiving a request corresponding to the image update event; and transmitting the updated image in response to the received request.

Claims

1. A remote user interface (UI) server comprising:

a UI application which provides a dynamic image;

a server communication module which transmits an image update event for the updated dynamic image, if the dynamic image is updated; and

a hypertext transfer protocol (HTTP) server which receives a request corresponding to the image update event and transmits the updated dynamic image in response to the received request.

2. The remote UI server of claim 1, wherein the server communication module transmits the image update event to a client, and the HTTP server receives the request from the client and transmits the updated dynamic image to the client.

3. The remote UI server of claim 2, wherein the HTTP server transmits position information of the updated dynamic image to the client.

4. The remote UI user interface server of claim 3, wherein the position information includes X-Y coordinates.

5. The remote UI server of claim 2, wherein the UI application generates a remote UI that includes the dynamic image, and the HTTP server transmits the remote UI to the client.

6. The remote UI server of claim 5, wherein the remote UI complies with a hypertext markup language format.

7. A remote user interface (UI) client comprising:

a browser module which displays a remote UI; and

a client communication module which is informed of an occurrence of an image update event in which an image in the remote UI is updated, and which informs the browser module of the occurrence of the image update event,

wherein the browser module transmits a request for the updated image according to the occurrence of the image update event and displays the updated image on the remote UI.

8. The remote user interface (UI) client of claim 7, wherein the client communication module is informed of the occurrence of the image update event by a server providing the remote UI, and the browser module transmits the request for the updated image to the server.

9. The remote UI client of claim 8, wherein the browser module receives position information of the updated image from the server and displays the updated image according to the position information.

10. The remote UI client of claim 9, wherein the position information includes X-Y coordinates.

11. The remote UI client of claim 8, wherein the remote UI complies with a hypertext markup language format.

12. A remote user interface (UI) proxy server comprising:

a control module which receives an updated image of a remote UI;

a relay communication module which informs a client that displays the remote UI of an occurrence of an image update event for the updated image; and

a hypertext transfer protocol (HTTP) server which receives a request corresponding to the image update event and transmits the updated image in response to the received request.

13. The remote user interface (UI) proxy server of claim 12, wherein the HTTP server receives the request corresponding to the image update event from the client, and transmits the update image to the client in response to the received request.

14. The remote UI proxy server of claim 13, wherein the HTTP server transmits position information of the updated image to the client.

15. The remote UI proxy server of claim 14, wherein the position information includes X-Y coordinates.

16. The remote UI proxy server of claim 13, wherein an UI application creates a remote UI that includes a dynamic image, and the HTTP server transmits the created remote UI to the client.

17. The remote UI proxy server of claim 16, wherein the remote UI complies with a hypertext markup language format.

18. A method for providing a remote user interface (UI), the method comprising:

if an image in a remote UI is updated, transmitting an image update event for the updated image;

receiving a request corresponding to the image update event; and

transmitting the updated image in response to the received request.

19. The method for providing a remote user interface (UI) of claim 18, wherein the image update event for the update image is transmitted to a client if the image in the remote UI is updated, and the updated image is transmitted to the client in response to a received request to display the updated image in the remote UI.

20. The method for providing a remote UI of claim 19, further comprising transmitting position information of the updated image to the client.

21. The method for providing a remote UI of claim 20, wherein the position information includes X-Y coordinates.

22. The method for providing a remote UI of claim 19, wherein the remote UI complies with a hypertext markup language format.

23. A method for providing a remote user interface (UI), the method comprising:

displaying a remote UI;

being informed of an occurrence of an image update event;

transmitting a request for an updated image; and

receiving the updated image and displaying the updated image.

24. The method for providing a remote UI of claim 23, wherein a server providing the remote UI informs of the occurrence of the image update event, the request for the updated image is transmitted from the server according to the occurrence of the image update event, and the updated image is displayed in the remote UI.

25. The method for providing a remote UI of claim 24, wherein the remote UI complies with a hypertext markup language format.
