Abstract

Disclosed is an apparatus for controlling an AV device, comprising a web browser receiving a structured document to contain a script from the AV device, and providing the same to a user, and a first program module including a function called by the script and transmitting information on a device control command to the AV device through a protocol previously defined by use of the function, wherein the AV device comprises a web server module transmitting the structured document and a second program module receiving the device control command information from the first program module through the protocol and controlling the AV device in response to the command information.

Claims

1. An apparatus for controlling an audio/video (AV) device, comprising:

a processor;

a web browser which receives a structured document including a script from the AV device, and which provides the structured document to a user, the script including a first function and a second function; and

a first program module, executed by the web browser in response to the user selecting first function of the script, which transmits a request to the AV device to query whether the first function of the script received from the AV device is supported by the AV device, receives a response from the AV device that indicates whether the first function is supported by the AV device, and transmits device control command information to the AV device through a protocol if the response received by the first program module indicates that the first function of the script is supported by the AV device,

wherein the AV device comprises a web server module which transmits the structured document and a second program module which receives the request, transmits the response, and receives the device control command information from the first program module through the protocol, and which controls the AV device in response to the device control command information,

wherein the first program module receives an event information from the second program module when an event is generated in the AV device, and calls the second function of the script to perform an operation corresponding to the received event information.

2. The apparatus as claimed in claim 1, wherein the device control command information includes information on channel control.

3. The apparatus as claimed in claim 1, wherein the device control command information includes information on volume control.

4. The apparatus as claimed in claim 1, wherein the device control command information includes information on PLAY control.

5. The apparatus as claimed in claim 1, wherein the device control command information includes information on channel control.

6. The apparatus as claimed in claim 1, wherein the device control command information includes information on volume control.

7. The apparatus as claimed in claim 1, wherein the device control command information includes information on PLAY control.

8. The apparatus as claimed in claim 1, wherein the processor controls the web browser.

9. An audio/video (AV) device, comprising:

a processor;

a web server module which transmits a structured document including a script a to an apparatus controlling an AV device, the script including a first function and a second function; and

a first program module which receives device control command information from the apparatus through a protocol and which controls the AV device in response to the device control command information,

wherein the web server module receives a query from the apparatus as to whether the first function of the script transmitted from the AV device to the apparatus is supported by the AV device in response to the user selecting the first function of the script and transmits a response to the apparatus that indicates whether the first function is supported by the AV device, and

wherein if the response indicates that the first function of the script is supported by the AV device, the first program module receives the device control command information from the apparatus through the protocol,

wherein the first program module transmits an event information to the second program module when an event is generated in the AV device, and the second function of the script transmitted from the AV device is used to perform an operation corresponding to the event information.

10. The AV device as claimed in claim 9, wherein the device control command information includes information on channel control.

11. The AV device as claimed in claim 9, wherein the device control command information includes information on volume control.

12. The AV device as claimed in claim 9, wherein the device control command information includes information on PLAY control.

13. The AV device as claimed in claim 9, wherein the device control command information includes information on channel control.

14. The AV device as claimed in claim 9, wherein the device control command information includes information on volume control.

15. The AV device as claimed in claim 9, wherein the device control command information includes information on PLAY control.

16. The apparatus as claimed in claim 9, wherein the processor controls the web browser.

17. A method for controlling an AV device, comprising:

(a) collecting information on a plurality of AV devices from the plurality of AV devices connected to a network and providing the information to a user;

(b) receiving a menu of a control item of a device controlling the AV device and a script corresponding to the control item, the script describing a function of the device controlling the AV device, to control the AV device if the AV device is selected to be controlled by the user from the information on the plurality of AV devices, and providing the menu of the control item to the user, the script including a first function and a second function;

(c) calling, by the script corresponding to the control item, a function to transmit the device control command information, as a called function, if the user specifically selects the control item from the menu provided in (b);

transmitting to the selected AV device a query whether the first function of the script corresponding to the control item and being received from the selected AV device is supported by the selected AV device, and receiving a response from the selected AV device that indicates whether the first function of the script corresponding to the control item is supported by the selected AV device; and

transmitting, by the called function, the device control command information to the selected AV device by use of a protocol if the response indicates that the first function of the script corresponding to the control item is supported by the selected AV device; and

(d) if an event is generated in the selected AV device, receiving information on the event as received event information from the selected AV device by use of the protocol, calling the second function of the script and performing an operation corresponding to the received event information by using the second function of the script.

18. The method as claimed in claim 17, wherein the information on the plurality of AV devices includes information on a device name, an image to indicate a device, a device model, the function provided by the device, and the script to carry out the function.

19. The method as claimed in claim 17, wherein the device control command information includes information on channel control.

20. The method as claimed in claim 17, wherein the device control command information includes information on volume control.

21. The method as claimed in claim 17, wherein the device control command information includes information on PLAY control.

22. The method as claimed in claim 17, wherein the information on the plurality of AV devices includes information on a device name, an image to indicate a device, a device model, the function provided by the device, and the script to carry out the function.

23. The method as claimed in claim 17, wherein the device control command information includes information on channel control.

24. The method as claimed in claim 17, wherein the device control command information includes information on volume control.

25. The method as claimed in claim 17, wherein the device control command information includes information on PLAY control.
