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 web browser receiving a structured document including a script from the AV device, and providing the structured document to a user; and

a first program module including a function called by the script and transmitting device control command information 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 device control command 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 second program module transmits information on an event as received event information to the first program module when the event is generated in the AV device, and the first program module transmits the received event information to the user through the web browser.

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

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

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

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

a web server module transmitting a structured document including a script, to an apparatus controlling an AV device, and

a first program module receiving device control command information from the apparatus through a protocol previously defined and controlling the AV device in response to the device control command information,

wherein the apparatus comprises a web browser providing the structured document to the user and a second program module including a function called by the script and transmitting the device control command information by use of the function through the protocol.

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 first program module transmits information on an event as received event information to the second program module when the event is generated in the AV device, and the second program module transmits the received event information to the user through the web browser.

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

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

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

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 to control the AV device if the AV device is selected as the selected AV device by the user from the information on the plurality of AV devices, and providing the menu of the control item to the user;

(c) transmitting device control command information corresponding to a control item to the selected AV device by a protocol previously defined, if the control item is specifically selected by the user from the menu provided in (b); and

(d) receiving information on an event as received event information from the selected AV device by use of the protocol, if the event is generated in the selected AV device, and processing a received event in response to the received event information.

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 (c) comprises:

calling, by a 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); and

transmitting, by the called function, the device control command information to the selected AV device by use of the protocol previously defined.

23. The method as claimed in claim 22, 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.

24. The method as claimed in claim 22, wherein the device control command information includes information on channel control.

25. The method as claimed in claim 22, wherein the device control command information includes information on volume control.

26. The method as claimed in claim 22, wherein the device control command information includes information on PLAY control.
