Abstract

A structure of a manifest file containing information on contents stored in a local storage device of a reproducing apparatus, a method of downloading the contents using the structure of the manifest file, and an apparatus for reproducing the contents. The structure of the manifest file includes contents information and 0version information of the manifest file and description information on at least one predetermined unit forming the contents.

Claims

1. A structure of a manifest file including contents information, wherein the manifest file comprises version information of the manifest file and description information on at least one predetermined unit forming the contents.

2. The structure of claim 1, wherein the manifest file further comprises:

a studio ID that represents information on producers that produce the contents;

a disc ID to identify information recording media storing the contents; and

at least a piece of contents information that represents description information in a predetermined unit that divides the contents recorded on the information recording media.

3. The structure of claim 2, wherein the version information comprises:

a version value of a current manifest file; and

a table regarding the predetermined unit relating to a deletion of contents.

4. The structure of any one of claims 1 through 3, wherein the predetermined unit is a play list that represents a reproduction unit forming the contents.

5. The structure of claim 3, wherein the table comprises a contents ID which is deleted, a related manifest file version, a related index table version, a related movie object version, a related play list version, and a related clip version.

6. The structure of claim 2, wherein the contents information comprises a contents ID, related title information, usage of the contents, a total data size, related play list files, related clip information files, and related stream files.

19. A computer readable recording medium having recorded thereon a program for executing the method of claim 5.

20. A computer readable recording medium having recorded thereon a program for executing the method of claim 6.

7. A method of downloading contents from an apparatus to reproduce the contents using a local storage, the method comprising:

receiving a contents download list prepared based on version information of a manifest file including information on contents stored in the local storage; and

selecting contents to be downloaded in the received contents download list, downloading the selected contents if a size of a local memory of the local storage is to determined to be sufficient to download the selected contents, and deleting a part of contents in the local storage device and downloading the selected contents if the size of the local memory is determined to not be sufficient to download the selected contents.

8. The method of claim 7, wherein the manifest file comprises version information of the manifest file and description information on at least one predetermined unit forming the contents.

9. The method of claim 7, wherein the manifest file comprises:

a studio ID that represents information on producers that produce the contents;

a disc ID to identify information recording media storing the contents; and

at least a piece of contents information that represents description information in a predetermined unit that divides the contents recorded on the information recording media.

10. The method of claim 7, further comprising downloading the selected contents based on a related version table included in the manifest file after deleting contents that are selected to be deleted by a user after the deletion of a part of the contents in the local storage device.

11. The method of claim 7, wherein a program used to delete contents after the deletion of a part of the local storage is a JAVA program stored as program data or realized as a resident program in a replacement apparatus.

12. The method according to claim 7, further comprising forming a virtual file system by reading directory information recorded in an information recording medium and the local storage.

13. The method according to claim 12, wherein, where data included in the virtual file system are based on data included in the information recording medium or the local storage such that the directory information is different for each, the virtual file system stores the files under a STREAM directory, a PLAYLIST directory, and/or a BD-J directory.

14. The method according to claim 12, wherein, where both the information recording medium and the local storage device include files having the same name, the virtual file system provides data to an application or a navigation engine based on data recorded on the information recording medium or data stored in the local storage.

15. The method according to claim 12, wherein, where both data stored in the information recording medium and the local storage are used, files recorded on the information recording medium or in the local storage are combined into a play list which is used to form the virtual file system.

16. The method according to claim 12, further comprising reproducing a single file including the directory information on the contents stored in both the information recording medium and the local storage using the virtual file system.

21. A computer readable recording medium having recorded thereon a program for executing the method of claim 7.

22. A computer readable recording medium having recorded thereon a program for executing the method of claim 8.

17. An apparatus to reproduce contents obtained by combining contents stored in a local storage device to store downloaded contents and/or contents read from a recording medium, the apparatus comprising:

an application manager to receive a contents download list prepared based on version information of a manifest file including information on contents stored in the local storage device, selecting contents to be downloaded in the received download list, to download the selected contents if a size of the local memory is determined to be sufficient to download the selected contents, and to delete a part of contents in the local storage device and downloading the selected contents if the size of the local memory is determined to not be sufficient.

18. The apparatus of claim 17, wherein the manifest file comprises:

a studio ID that represents information on producers that produce the contents;

a disc ID to identify information recording media storing the contents; and

at least a piece of contents information that represents description information in a predetermined unit that divides the contents recorded on the information recording media.

23. An application manager of an apparatus to reproduce contents obtained by combining contents stored in a local storage device to store downloaded contents and/or contents read from a recording medium to receive a contents download list based on version information of a manifest file including information on contents stored in the local storage device, to select contents to be downloaded in the received download list, to download the selected contents if a size of the local memory is determined to be sufficient to download the selected contents, and to delete a part of contents in the local storage device and download the selected contents if the size of the local memory is determined to not be sufficient, wherein the manifest file comprises:

a studio ID that represents information on producers that produce the contents;

a disc ID to identify information recording media storing the contents; and

at least a piece of contents information that represents description information in a predetermined unit that divides the contents recorded on the information recording media.
