Abstract

A digital content distribution method and system for delivering a content package including a Digital Rights Management (DRM) content and an advertisement content which is played to generate a license for playing the DRM content is disclosed. The content object format of the present invention includes a target content object; a pilot content object containing specific advertisement data; and a header indicating locations of the target content object and the pilot content object.

Claims

1. A content object format configuration system, comprising:

means for generating a target content object;

means for generating a pilot content object containing specific advertisement data; and

means for generating a header indicating locations of the target content object and the pilot content object.

2. The system of claim 1, wherein the target content object and the pilot content object are packaged in a single Digital Rights Management Content Format (DCF), and the header includes metadata information related to configuration of the DCF.

3. The system of claim 2, wherein the pilot content object is positioned before and after the target content object in a content region of the DCF.

4. The system of claim 3, wherein the header comprises offset information indicating a position of the pilot content object.

5. The system of claim 2, wherein the target content object and the pilot content object are configured in a multipart DCF, the target content object being included in a content region of a first part of the multipart DCF, the pilot content object being included in a content region of a second part of the multipart DCF, and the header is included in the first part DCF.

6. The system of claim 5, wherein the header comprises a pilot content identifier for identifying the pilot content object.

7. The system of claim 2, wherein the target content object is included in a content region of the DCF, and the pilot content object is included in an extended box following the content region of the DCF.

8. The system of claim 7, wherein the header comprises information indicating a location of the pilot content object in the extended box.

9. The system of claim 2, wherein the pilot content object is included in a mutable information box following at least one DCF.

10. The system of claim 9, wherein the header comprises information indicating a location of the pilot content object in the mutable information box.

11. The system of claim 1, wherein the header is configured using textual headers or DCF extensibility.

12. A package content configuration method for carrying at least one content object, comprising:

forming a package content containing a target content object and a pilot content object having a specific advertisement data; and

adding a header indicating positions of the target content object and the pilot content object according to a package content format type.

13. The package content configuration method of claim 12, wherein forming a package content comprises:

positioning the pilot content object before or after the target content in a content region of the package content; and

inserting offset information indicating the position of the pilot content object into the header

14. The package content configuration method of claim 12, wherein forming a package content comprises:

packaging the package content into a multipart Digital Rights Management Content Format (DCF);

placing the target content object in a content region of a first part of the multipart DCF;

placing the pilot content object in a content region of a second part of the multipart DCF; and

inserting a pilot content identifier indicating a position of the pilot content object in the header.

15. The package content configuration method of claim 12, wherein forming the package content comprises:

forming a box in an extended box of the package content;

packaging the pilot content object in the extended box; and

inserting information indicating the position of the pilot content object in the extended box.

16. The package content configuration method of claim 12, wherein forming the package content comprises:

adding a mutable information box following at least one DCF;

placing the pilot content object in the mutable information box; and

inserting information indicating a position of the pilot content object into the header.

17. The package content configuration method of claim 12, wherein the header is configured using textual headers or DCF extensibility, and includes metadata information related to a configuration of the DCF.

18. A content playback method of a mobile terminal, comprising:

checking, when a content playback request for playing a content is detected, whether a header indicating a pilot content object exists in the content;

playing, when a header indicating a pilot content object exists in the content, the pilot content object according to information on the pilot content object, the information being included in a header; and

playing a target content object using a license generated while playing the pilot content object.

19. The content playback method of claim 18, further comprising playing, when no header indicating a pilot object exists in the content, the content using a given license.

20. The content playback method of claim 18, wherein the header comprises additional information corresponding to types of the target content object and the pilot content object.
