Abstract

A method and an apparatus are provided for providing a remote User Interface (UI) to a terminal in a remote UI system. The method includes downloading, by the first terminal, an application from a remote server; driving the application; requesting a new application from the remote server; receiving the new application from the remote server; driving the new application; requesting a second terminal to a change the control UI according to the new application; receiving a message requesting a new control UI for controlling the new application from the second terminal; and providing the new control UI for controlling the new application to the second terminal in response to the message.

Claims

1. A method for providing a control User Interface (UI) by a first terminal in a remote UI system, the method comprising:

downloading, by the first terminal, an application from a remote server;

driving the application;

requesting a new application from the remote server;

receiving the new application from the remote server;

driving the new application;

requesting a second terminal to a change the control UI according to the new application;

receiving a message requesting a new control UI for controlling the new application from the second terminal; and

providing the new control UI for controlling the new application to the second terminal in response to the message.

2. The method of claim 1, wherein requesting the second terminal to change the control UI comprises:

requesting the change of the control UI to a Remote Control Function (RCF) Control Point (CP) in the first terminal using a parameter value of an Application Programming Interface (API) provided by an RCF plug-in in the first terminal; and

requesting, by the RCF CP, the second terminal to the change the control UI using a command Uniform Resource Identifier (URI) provided by the second terminal.

3. The method of claim 2, wherein the parameter value includes one of “

/rcf/request_cui”

, “

/rcf/request_msg”

, and “

/rcf/create_app”

.

4. The method of claim 2, wherein, when the first terminal does not have the command, the RCF CP connects to the second terminal through an embedded server of the first terminal to obtain the command URI from the second terminal.

5. The method of claim 2, wherein the RCF CP adds a message value to the command URI and transmits the message value-added particular command URI to the second terminal.

6. The method of claim 5, wherein the message value is changed according to the parameter value.

7. The method of claim 6, wherein the message requesting the new control UI includes the message value.

8. The method of claim 1, wherein providing the new control UI to the second terminal comprises one of:

receiving the new control UI for controlling the new application from the remote server and providing the received new control UI to the second terminal; and

providing a control UI existing in the first terminal to the second terminal.

9. A terminal apparatus for providing a control User Interface (UI) in a remote server, the terminal apparatus comprising:

a handler for driving an application downloaded from the remote server;

a Remote Control Function Control Point (RCF CP) for sending a control UI change request to another terminal, when a new application is driven by the handler without a request from the another terminal; and

an embedded server for receiving a message requesting a new control UI for controlling the new application from the another terminal and providing the new control UI for controlling the new application to the another terminal.

10. The terminal apparatus of claim 9, wherein the handler requests the control UI change to the RCF CP using a parameter value of an Application Programming Interface (API) provided from an RCF plug-in, and

the RCF CP sends the control UI change request to the another terminal using a command Uniform Resource Identifier (URI) provided by the another terminal.

11. The terminal apparatus of claim 10, wherein the parameter value comprises one of:

“

/rcf/request_cui”

;

“

/rcf/request_msg”

; and

“

/rcf/create_app”

.

12. The terminal apparatus of claim 10, wherein, when the terminal apparatus does not have the command URI, the RCF CP obtains the command URI from the another terminal by performing a Device Discovery &

Description procedure for connection to the another terminal through the embedded server.

13. The terminal apparatus of claim 10, wherein the RCF CP adds a message value to the command URI and transmits the message value-added particular command URI to the another terminal.

14. The terminal apparatus of claim 13, wherein the message value changes according to the parameter value.

15. The terminal apparatus of claim 14, wherein the message requesting the new control UI comprises the message value.

16. The terminal apparatus of claim 9, wherein the embedded server receives the new control UI for controlling the new application from the remote server and provides the received new control UI to the second terminal, or provides a control UI existing in the first terminal to the second terminal.
