Abstract

An information playback method includes reading out information from a recording medium storing a stream which includes meta data of a moving picture capable of being played back upon playback of a video content, and which is formed of access units as data units capable of being processed independently, and storing specific information used to select a stream corresponding to the meta data in accordance with a moving picture playback period of the video content, and playing back the video content, and playing back the meta data with selecting a stream corresponding to the meta data on the basis of the specific information.

Claims

1. An information recording medium for use in playback information recorded thereon, the information comprising:

a stream which includes meta data of a moving picture capable of being played back upon playback of a video content, and which is formed of access units as data units capable of being processed independently; and

specific information used to select a stream corresponding to the meta data of the moving picture in accordance with a moving picture playback period of the video content.

2. The medium according to claim 1, wherein the video content includes a set of one or more titles, and the moving picture playback period of the video content corresponds to a playback period of the title.

3. The medium according to claim 1, wherein a playback order of the video content is designated by a program chain defined by a set of one or more programs, and the moving picture playback period of the video content corresponds to a playback period of the program chain.

4. The medium according to claim 1, wherein the playback period is specified by time information.

5. The medium according to claim 1, wherein the video content includes at least one of a moving picture data stream corresponding to the video content, and audio and caption data streams corresponding to the video content, at least one of the moving picture, audio, and caption data streams has an attribute associated with itself, and the specific information includes information associated with the attribute.

6. The medium according to claim 5, wherein the video content includes a plurality of audio data streams of one or more types, and the information associated with the attribute includes a stream number of each audio data stream.

7. The medium according to claim 5, wherein the video content includes a plurality of caption data streams using one or more types of languages, and the information associated with the attribute includes a stream number of each caption data stream.

8. The medium according to claim 5, wherein the video content includes a plurality of multi-angle video data streams, and the information associated with the attribute includes a stream number of each multi-angle video data stream.

9. The medium according to claim 5, wherein a video picture of the video content is displayed at one of two or more types of aspect ratios, and the information associated with the attribute includes information used to specify one of the aspect ratios.

10. The medium according to claim 1, wherein each access unit has identification information used to identify that access unit, and the identification information corresponds to the specific information.

11. An information playback method, comprising:

reading out information from a recording medium storing a stream which includes meta data of a moving picture capable of being played back upon playback of a video content, and which is formed of access units as data units capable of being processed independently, and storing specific information used to select a stream corresponding to the meta data in accordance with a moving picture playback period of the video content; and

playing back the video content, and playing back the meta data with selecting a stream corresponding to the meta data on the basis of the specific information.

12. The method according to claim 11, wherein the video content includes a set of one or more titles, and the moving picture playback period of the video content corresponds to a playback period of the title.

13. The method according to claim 11, wherein a playback order of the video content is designated by a program chain defined by a set of one or more programs, and the moving picture playback period of the video content corresponds to a playback period of the program chain.

14. The method according to claim 11, wherein the playback period is specified by time information.

15. The method according to claim 11, wherein the video content includes at least one of a moving picture data stream corresponding to the video content, and audio and caption data streams corresponding to the video content, at least one of the moving picture, audio, and caption data streams has an attribute associated with itself, and the specific information includes information associated with the attribute.

16. An information recording method, comprising:

recording on a first area of an information recording medium, a stream which includes meta data of a moving picture capable of being played back upon playback of a video content, and which is formed of access units as data units capable of being processed independently; and

recording on a second area of the information recording medium, specific information used to select a stream corresponding to the meta data of the moving picture in accordance with a moving picture playback period of the video content.

17. The method according to claim 16, wherein the video content includes a set of one or more titles, and the moving picture playback period of the video content corresponds to a playback period of the title.

18. The method according to claim 16, wherein a playback order of the video content is designated by a program chain defined by a set of one or more programs, and the moving picture playback period of the video content corresponds to a playback period of the program chain.

19. The method according to claim 16, wherein the playback period is specified by time information.

20. The method according to claim 16, wherein the video content includes at least one of a moving picture data stream corresponding to the video content, and audio and caption data streams corresponding to the video content, at least one of the moving picture, audio, and caption data streams has an attribute associated with itself, and the specific information includes information associated with the attribute.
