Abstract

A dynamic user interface (UI) system and method is provided for remote controlling of a legacy device, which is not compatible with a peer-to-peer (P2P) middleware, through a P2P network. The dynamic UI system of the present includes at least one legacy device, a proxy for registering and managing the at least one legacy device and supporting a dynamic remote control user interface using a multi legacy device control protocol, and an edge peer for downloading the dynamic remote control user interface from the proxy and requesting control of the at least one legacy device to the proxy.

Claims

1. A dynamic user interface system for remotely controlling a legacy device, comprising:

at least one legacy device;

a proxy for registering and managing the at least one legacy device, and supporting a dynamic remote control user interface using a multi legacy device control protocol; and

an edge peer for downloading the dynamic remote control user interface from the proxy and requesting control of the at least one legacy device to the proxy.

2. The dynamic user interface system of claim 1, wherein the proxy comprises:

a dynamic user interface server for providing user interface information to the edge peer;

a content sharing service unit for transmitting the user interface information provided by the dynamic user interface server to edge peer;

a multi legacy device control protocol request handler for processing a remote control request message received from the edge peer; and

a device management unit for managing the dynamic remote control user interfaces of the legacy devices.

3. The dynamic user interface system of claim 2, wherein the proxy further comprises a proxy advertisement manager for generating, transmitting, and parsing proxy advertisements.

4. The dynamic user interface system of claim 3, wherein the proxy advertisement manager comprises:

a generator for generating a proxy advertisement; and

a parser for parsing the proxy advertisement.

5. The dynamic user interface system of claim 2, wherein the proxy further comprises a security manager for authenticating the edge peer.

6. The dynamic user interface system of claim 1, wherein the edge peer comprises:

a dynamic user interface client for receiving the dynamic remote control user interface and transmitting a remote control message to the proxy; and

a multi legacy device control protocol response handler for processing a remote control result message received from the proxy.

7. The dynamic user interface system of claim 1, wherein the multi legacy device control protocol defines a proxy advertisement, a legacy device interface advertisement, a control message for controlling the legacy device, a control response message containing a value resulted from controlling the legacy device.

8. A device registration method for remotely controlling legacy devices, comprising:

advertising a proxy using a proxy advertisement;

;

receiving a request for registering a legacy device;

generating a universal unique identifier to be assigned to the legacy device;

updating the proxy advertisement; and

registering a user interface of the legacy device.

9. The device registration method of claim 8, wherein the proxy advertisement comprises a unique identifier of the proxy, a unique group identifier of a group in which the proxy participates, and version information of the proxy.

10. The device registration method of claim 8, wherein the proxy advertisement comprises a unique identifier, type, name, detailed description, and extendibility information of the legacy device.

11. The device registration method of claim 8, wherein the proxy advertisement comprises information on a platform supporting the dynamic remote control user interface;

information on a title, width, and height of the dynamic remote control user interface; and

dynamic remote control extendibility information.

12. A dynamic user interface method for remotely controlling legacy devices, comprising:

detecting, at an edge peer, a proxy advertisement;

selecting a legacy device referring the proxy advisement;

downloading a dynamic remote control user interface for the selected legacy device;

executing the downloaded dynamic remote control user interface;

transmitting a control request message for controlling the legacy device; and

receiving a control result message containing a value resulted from controlling the legacy device.

13. The dynamic user interface method of claim 12, wherein the control request message comprises a unique identifier of a proxy as a receiver, a unique identifier of the legacy device to be controlled, a control command, and a control parameter.

14. The dynamic user interface method of claim 12, wherein the control result message comprises a unique identifier of a proxy as a sender, a unique identifier of a peer edge as a receiver, a time stamp, a control command, and a control result indicator.
