Abstract

A method and apparatus for acquiring DRM contents in a mobile communication terminal at a reduced expense by acquiring information about the DRM contents provided through a plurality of content providers are provided. The method and apparatus for acquiring DRM contents includes acquiring price information for DRM contents provided from a plurality of content providers upon request for acquiring DRM contents, selecting a content provider using the acquired price information and acquiring the DRM contents and a license from the selected content provider. Therefore, DRM contents can be acquired by selecting the least expensive DRM content provider at a present point in time using a content information server in which the content information is stored and then connecting to the corresponding content provider to ultimately reduce the cost for acquiring the DRM contents.

Claims

1. A method of acquiring digital rights management (DRM) contents from a plurality of content providers comprising:

acquiring information about DRM contents;

selecting a content provider using the acquired content information; and

acquiring DRM contents and a license from the selected content provider.

2. The method of claim 1, wherein the acquiring of the content information comprises:

connecting to a content information server comprising the content information;

sending a request for the content information to the content information server; and

acquiring the content information from the content information server.

3. The method of claim 1, wherein selecting a content provider comprises:

displaying price information of DRM content for at least one content provider using the acquired content information; and

selecting one of the displayed content providers.

4. The method of claim 1, wherein the content provider comprises a content server and a license server.

5. The method of claim 4, wherein the acquiring of the DRM contents and license comprises:

connecting to the content server of the selected content provider;

acquiring the DRM contents from the connected content server;

connecting to the license server of the selected content provider; and

acquiring a license for the DRM contents from the connected license server.

6. The method of claim 1, wherein the content information comprises price information of the DRM contents of the content provider.

7. A method of reacquiring DRM contents from a plurality of content providers comprising:

displaying expiration of a license for DRM contents;

receiving a request for reacquiring the DRM contents for which the license expiration is displayed;

acquiring information about the DRM contents for which reacquisition is requested;

selecting a content provider using the acquired content information; and

acquiring the DRM contents and the license from the selected content provider.

8. The method of claim 7, wherein the displaying of the expiration of the license comprises:

requesting execution of the DRM contents;

determining whether the license has expired for the DRM contents for which the execution is requested; and

displaying, if the license for the DRM contents has expired, a message for informing of the expiration of the license.

9. The method of claim 7, wherein the acquiring of the content information comprises:

connecting to a content information server comprising the content information;

sending a request for the content information to the content information server; and

acquiring the content information from the content information server.

10. The method of claim 7, wherein selecting a content provider comprises:

displaying price information of the DRM content for at least one content provider using the acquired content information; and

selecting one of the displayed content providers.

11. The method of claim 7, wherein the content provider comprises a content server and a license server.

12. The method of claim 11, wherein the acquiring of the DRM contents and license comprises:

connecting to the content server of the selected content provider;

acquiring the DRM contents from the connected content server;

connecting to the license server of the selected content provider; and

acquiring the license for the DRM contents from the connected license server.

14. The method of claim 7, wherein the content information comprises price information of the DRM contents of the content provider.

13. (canceled)

15. A mobile communication terminal comprising:

an information acquisition unit for acquiring information about DRM contents;

a provider selecting unit for selecting a content provider using the acquired content information;

a content acquisition unit for acquiring DRM contents and a license from the selected content provider; and

a network communication unit for receiving at least one of the acquired DRM contents, license, and content information.

16. The mobile communication terminal of claim 15, wherein the information acquisition unit acquires the content information by connecting to a content information server comprising the content information.

17. A method of providing information about DRM contents in a mobile communication terminal comprising:

receiving a request signal for content information from the mobile communication terminal;

extracting the requested content information based on the request signal for content information; and

transmitting the extracted content information to the mobile communication terminal.

18. The method of claim 17, wherein the receiving of the request signal comprises:

connecting to the mobile communication terminal; and

receiving the request signal for information about specific DRM contents from the connected mobile communication terminal.

19. The method of claim 17, wherein the extracting of the requested content information comprises using a content information database in which various content information is stored.

20. The method of claim 19, wherein the extracting of the requested content information comprises:

searching the content information database to determine whether the requested content information is in the content information database; and

extracting, if the requested content information is in the content information database, the content information from the content information database.

21. The method of claim 20, further comprising:

if the requested content information is not in the content information database in the searching of the content information database,

connecting to a content provider;

requesting the content information to the content provider;

acquiring the requested content information from the content provider;

storing the acquired content information in the content information database; and

extracting the stored content information.

22. The method of claim 21, wherein, if there is a plurality of content providers, connecting to the content providers, requesting the content information, acquiring the requested content information, and storing the acquired content information, are sequentially repeated for each of the plurality of content providers before extracting the stored content information.

23. The method of claim 19, wherein the extracting of the requested content information comprises:

connecting to a content provider;

sending a request for the content information to the content provider;

acquiring the requested content information from the content provider;

storing the acquired content information in the content information database; and

extracting the stored content information.

24. The method of claim 23, wherein, if there is a plurality of content providers, the connecting to the content providers, the requesting of the content information, the acquiring of the requested content information, and the storing of the acquired content information, are sequentially repeated for each of the plurality of the content providers before extracting the stored content information.

26. (canceled)

27. A DRM content acquisition system comprising:

a plurality of content providers, each comprising a content server for providing DRM contents and a license server for providing a license for the DRM contents;

a content information server for collecting and storing content information from the content provider; and

a mobile communication terminal for acquiring the content information from the content information server, selecting a content provider based on the acquired content information, and acquiring the DRM contents and the license from the selected content provider.

28. The DRM content acquisition system of claim 27, wherein the content information stored in the content server is price information for each content provider of the DRM contents.
