Abstract

The present invention relates to a recording medium containing moving picture data and additional information thereof and to reproducing method and apparatus of the recording medium. The present recording medium has script files including additional information about moving picture data, e.g., scene descriptive text and introduction of characters, etc. In addition, information linking each script file with a section of moving picture data to be presented with contents of the script file is included in a link data file or is contained in a filename of the script file. In reproduction of the recording medium, a script file linked with presently reproduced moving picture data section is determined and searched for based on the link data file or every filename of the script files, and contents of the found script file are presented together with the presently reproduced moving picture data. Furthermore, previously presented additional information is removed depending on data or filename of the found script file.

Claims

1. A method of providing information for managing reproduction of video data, comprising:

providing a metadata indicator for indicating whether or not metadata set exists in a specific stream including the metadata indicator, the metadata set being a set of metadata and an additional information describing the video data, and a linking information for associating the metadata set with the video data,

wherein the metadata indicator includes one of a first metadata indicator value indicating that the metadata set associated with the video data does not exist in the specific stream and a second metadata indicator value indicating that the metadata set associated with the video data exists in the specific stream wherein the metadata indicator is a flag, and

wherein the metadata set includes metadata having one of a plurality of predetermined formats.

2. The method of claim 1, wherein the metadata set comprises one or more metadata for describing one or more sections of the video data.

3. The method of claim 2, wherein the metadata comprises one or more metadata sections, wherein the metadata section is decoded at a specific instant in a time.

4. The method of claim 1, wherein the metadata set comprises one or more metadata in a same format.

5. The method of claim 1, wherein the metadata set is provided separately from the video data.

6. A non-transitory storage medium storing a data structure for managing reproduction of video data from the storage medium, comprising:

a data area storing video data;

a navigation area storing a metadata indicator for indicating whether or not metadata set exists in a specific stream including the metadata indicator, the metadata set being a set of metadata and an additional information describing the video data, and a linking information for associating the metadata set with the video data,

wherein the metadata indicator includes one of a first metadata indicator value indicating that the metadata set associated with the video data does not exist in the specific stream and a second metadata indicator value indicating that the metadata set associated with the video data exists in the specific stream wherein the metadata indicator is a flag, and

wherein the metadata set includes metadata having one of a plurality of predetermined formats.

7. The medium of claim 6, wherein the metadata set comprises one or more metadata for describing one or more sections of the video data.

8. The medium of claim 7, wherein the metadata comprises one or more metadata sections, wherein the metadata section is decoded at a specific instant in a time.

9. The medium of claim 6, wherein the metadata set comprises one or more metadata in a same format.

10. The medium of claim 6, wherein the metadata set is provided separately from the video data.

11. A method of processing metadata set associated with video data, comprising:

identifying the metadata set associated with the video data on a basis of a metadata indicator for indicating whether or not metadata set exists in a specific stream including the metadata indicator, the metadata set being a set of metadata and an additional information describing the video data, and a linking information for associating the metadata set with the video data,

wherein the metadata indicator includes one of a first metadata indicator value indicating that the metadata set associated with the video data does not exist in the specific stream and a second metadata indicator value indicating that the metadata set associated with the video data exists in the specific stream wherein the metadata indicator is a flag, and

wherein the metadata set includes metadata having one of a plurality of predetermined formats;

and processing the identified metadata set to output the metadata set together with the associated video data.

12. The method of claim 11, further comprising:

storing temporarily the metadata set and the management information, and

wherein the identifying step identifies the specific metadata set associated with the video data from the stored metadata set and the processing step includes decoding the specific metadata and decoding the video data.

13. The method of claim 12, further comprising:

reproducing the decoded metadata set in synchronized manner with the decoded video data.

14. The method of claim 11, wherein the identifying step specifies the metadata set based on the linking information if the metadata set is present in the specific stream based on the metadata indicator.

15. The method of claim 11, wherein the metadata comprises one or more metadata sections, wherein the processing step processes the metadata sections in a specific instant in a time.

16. A method of processing metadata set associated with video data, comprising:

receiving a metadata indicator for indicating whether or not metadata set exists in a specific stream including the metadata indicator, the metadata set being a set of metadata and an additional information describing the video data, and a linking information for associating the metadata set with the video data,

wherein the metadata indicator includes one of a first metadata indicator value indicating that the metadata set associated with the video data does not exist in the specific stream and a second metadata indicator value indicating that the metadata set associated with the video data exists in the specific stream wherein the metadata indicator is a flag, and

wherein the metadata set includes metadata having one of a plurality of predetermined formats;

and utilizing the linking information to output the metadata set together with the associated video data.

17. The method of claim 16, further comprising:

identifying the metadata set based on the linking information if the metadata set is present in the specific stream on a basis of the metadata indicator.

18. An apparatus of processing metadata set associated with video data, comprising:

a controller configured to identify the metadata set associated with the video data on a basis of a metadata indicator for indicating whether or not metadata set exists in a specific stream for the including the metadata indicator, the metadata set being a set of metadata and an additional information describing the video data, and a linking information for associating the metadata set with the video data,

wherein the metadata indicator includes one of a first metadata indicator value indicating that the metadata set associated with the video data does not exist in the specific stream and a second metadata indicator value indicating that the metadata set associated with the video data exists in the specific stream wherein the metadata indicator is a flag, and

wherein the metadata set includes metadata having one of a plurality of predetermined formats;

and a data processor, coupled to the controller, to process the identified metadata set to output the metadata set together with the associated video data.

19. The apparatus of claim 18, further comprising:

a data storage to temporarily store the metadata set and the management information, and

wherein the controller identifies the specific metadata set associated with the video data from the stored metadata set and the processor decodes the specific metadata and the video data.

20. The apparatus of claim 19, wherein the data processor reproduces the decoded metadata set in synchronized manner with the decoded video data, according to a control of the controller.

21. The method of claim 18, wherein the metadata comprises one or more metadata sections, wherein the data processor processes the metadata sections in a specific instant in a time.
