Abstract

A contents player, a method for playing contents, a mobile code providing device and a method for providing a mobile code, that are applied to a digital rights management (DRM) system. The contents player applied to the DRM system, according to an embodiment of the present invention, includes a network interface part which receives the contents and additional data regarding the contents; a DRM module management part which demodulates the contents by a predetermined DRM module and if the DRM module capable of demodulating the contents does not exist, updates the DRM module through the network interface part; and a contents playing part which plays the demodulated contents. Accordingly, all the contents provided by a content provider can be used regardless of the DRM technology applied to the contents and a platform of a demodulator.

Claims

1. A contents player applied to a digital rights management (DRM) system, the contents player comprising:

a network interface part which receives contents which are encrypted by a DRM technology and additional data regarding the contents;

a DRM module management part which demodulates the contents by a DRM module, and if the DRM module is not capable of demodulating the contents, updates the DRM module through the network interface part; and

a contents playing part which plays the contents, which are demodulated.

2. The contents player of claim 1, wherein the additional data comprises meta data of the contents and meta data interpretation module information.

3. The contents player of claim 2, wherein the meta data interpretation module information includes a uniform resource identifier which receives the DRM module.

4. The contents player of claim 2, further comprising a meta data interpretation part which analyzes the meta data by a meta data interpretation module.

5. The contents player of claim 4, wherein, if the meta data interpretation module does not correspond to the meta data, the meta data interpretation part updates the meta data interpretation module through the network interface part.

6. The contents player of claim 5, wherein the meta data interpretation module is provided in the form of a Java-based mobile code.

7. The contents player of claim 1, wherein the DRM module is provided in the form of a Java-based mobile code.

8. The contents player of claim 1, wherein the contents are received from a contents providing server.

9. The contents player of claim 8, wherein the contents providing server comprises a DRM module database which stores at least one DRM module.

10. A method for playing contents, applied to a digital rights management (DRM) system, the method comprising:

receiving contents encrypted by a DRM technology from a contents providing server and additional data regarding the contents;

demodulating the contents by a DRM module;

if the DRM module is not capable of demodulating the contents in the demodulating operation, updating the DRM module and demodulating the contents by the DRM module which is updated; and

playing the contents which have been demodulated.

11. The method of claim 10, wherein the additional data comprises meta data of the contents and meta data interpretation module information.

12. The method of claim 11, wherein the meta data interpretation module includes a uniform resource identifier which receives the DRM module.

13. The method of claim 11, further comprising analyzing the meta data by a meta data interpretation module.

14. The method of claim 13, further comprising, if the meta data interpretation module does not correspond to the meta data, updating the meta data interpretation module.

15. The method of claim 14, wherein the meta data interpretation module is provided in the form of a Java-based mobile code.

16. The method of claim 10, wherein the DRM module is provided in the form of a Java-based mobile code.

17. A mobile code providing device comprising:

a network interface part which receives a mobile code requesting signal from a contents player;

a mobile code request processing part which extracts a mobile code of a digital rights management (DRM) module and a meta data interpretation module from a database based on the requesting signal which was received; and

a mobile code transmission part which transmits the mobile code of the DRM module which is extracted and the meta data interpretation module to the contents player.

18. The mobile code providing device of claim 17, wherein the database comprises a DRM module database which stores the mobile code of the DRM module and a meta data interpretation module database which stores the mobile code of the meta data interpretation module.

19. A method for providing a mobile code to a contents player, the method comprising:

receiving a mobile code requesting signal from the contents player; and

extracting a mobile code based on the requesting signal which is received and transmitting the mobile code which is extracted to the contents player.

20. The method of claim 19, further comprising, after receiving the mobile code requesting signal, transmitting an error message to the contents player if the mobile code does not exist.
