Abstract

An audio/visual (AV) task calculation method, a method of providing summary information for an AV task calculation, and an apparatus for the same are provided. The method includes requesting summary information on media data from an AV server storing media data, receiving the summary information from the AV server, and calculating an AV task through the received summary information.

Claims

1. A method of calculating an audio/visual (AV) task, the method comprising:

requesting summary information on media data from an AV server;

receiving the summary information from the AV server; and

calculating an AV task through the received summary information.

2. The method of claim 1, wherein the requesting comprise:

creating a summary information request message; and

transmitting the summary information request message to the AV server.

3. The method of claim 2, wherein the transmitting comprises:

transmitting the summary information request message through a search operation or a browse operation of Universal Plug and Play (UPnP) AV architecture.

4. The method of claim 2, wherein the summary information request message comprises at least one of type and file format of media data that needs the summary information.

5. The method of claim 4, wherein the controlling comprises several types or file formats of media data.

6. The method of claim 1, wherein the received summary information comprises the number of media data files stored in the AV server.

7. The method of claim 6, wherein the received summary information comprises the number of media data files by type or file format.

8. A method of providing summary information for calculating an audio/visual (AV) task, comprising:

receiving a summary information request message from a control device that calculates AV task; and

transmitting summary information on predetermined media data as a response to the summary information request message to the control device.

9. The method of claim 8, further comprising searching for media data by type or file format, wherein the searching is performed prior to the receiving.

10. The method of claim 8, wherein the summary information is on the media data identified through the summary information request message.

11. The method of claim 8, wherein the summary information request message comprises at least one of type and file format of media data that needs the summary information.

12. The method of claim 8, wherein the transmitting comprises:

searching for the media data identified through the summary information request message;

creating a response message comprising summary information on the retrieved media data; and

transmitting the created response message to the control device.

13. The method of claim 8, wherein the summary information comprises a number of media data by type or file format of the media data identified through the summary information request message.

14. A control device comprising:

a message-creating module that creates a summary information request message and sends the message to an audio/visual (AV) server;

a communication module that transmits the summary-information-request message to the AV server and receives the summary information from the AV server; and

an AV task calculating module that calculates an AV task through the received summary information.

15. The apparatus of claim 14, wherein the summary information request message creating module enables the summary information request message to be included in a search operation or a browse operation of Universal Plug and Play (UPnP) AV architecture.

16. The apparatus of claim 14, wherein the summary information request message comprises at least one of type and file format of media data that needs the summary information.

17. The apparatus of claim 16, wherein the summary information request message comprises several types or file formats of media data.

18. The apparatus of claim 14, wherein the received summary information comprises a number of media data files stored in the AV server.

19. The apparatus of claim 18, wherein the received summary information includes the number of media data by type or file format.

20. An AV server comprising:

a communication module that receives a summary information request message from a control device calculating an audio/visual (AV) task;

a message-creating module that creates a response message including summary information on predetermined media data as a response to the summary information request message;

a control module that transmits the response message to the control device via the communication module.

21. The server of claim 20, further comprising:

a search module that searches for media data by type or file format;

wherein the searching is performed prior to receiving the summary information request message.

22. The server of claim 20, wherein the summary information is on the media data identified through the summary information request message.

23. The server of claim 20, further comprising:

a storage module that stores at least one media data file; and

a search module that searches for the media data identified through the summary information request message;

wherein the message-creating module creates a response message including summary information on the media data retrieved by the search module.

24. The server of claim 20, wherein the summary information request message comprises at least one of type and file format of media data that needs the summary information.

25. The server of claim 20, wherein the summary information comprises a number of media data files by type or file format of the media data identified through the summary information request message.
