Abstract

A navigation area of the recording medium stores navigation management information associated with each title of video data. The navigation management information indicates at least one reproduction path for the title of video data and includes an attribute field indicating at least one attribute of the navigation management information.

Claims

1. A recording medium storing a data structure for managing reproduction of video data having multiple titles, comprising:

a data area storing a stream file including the video data;

a playlist area storing a playlist file including at least one playitem identifying a playing interval of a clip of the video data, the playlist file being separate from the stream file; and

a navigation area storing a navigation file separate from the playlist file, the navigation file including navigation management information indicating the playlist file, the navigation management information indicating whether a title search is permitted or prohibited for a title managed by the navigation management information.

2. The recording medium of claim 1, wherein at least two playitems, each from a different playlist file, identify a same clip.

3. The recording medium of claim 1, wherein at least one clip represents video data common to more than one reproduction path.

4. The recording medium of claim 1, wherein at least one clip represents video data for a single reproduction path.

5. The recording medium of claim 1, wherein the video data are recorded in forms of packets.

6. The recording medium of claim 1, wherein the video data has multiple reproduction path.

7. The recording medium of claim 5, wherein at least a portion of the packets belonging to different reproduction paths are multiplexed.

8. The recording medium of claim 1, wherein the video data includes video data for a director'"'"'s cut title and video data for a theatrical title.

9. A method of recording a data structure for managing reproduction of video data having multiple titles on a recording medium, the method comprising:

recording a stream file including the video data on the recording medium;

recording a playlist file including at least one playitem identifying a playing interval of a clip of the video data on the recording medium, the playlist file being separate from the stream file; and

recording a navigation file, separate from the playlist file, the navigation file including navigation management information indicating the playlist file, the navigation management information indicating whether a title search is permitted or prohibited for a title managed by the navigation management information.

13. The method of claim 9, further comprising:

recording the video data having multiple titles as a unit of packets in the data area, wherein at least a portion of the packets belonging to different reproduction paths are multiplexed.

14. The method of claim 9, wherein the video data has multiple reproduction paths.

15. The method of claim 9, wherein the video data includes video data for a director'"'"'s cut title and video data for a theatrical title.

10. A method of reproducing a data structure for managing reproduction of video data having multiple titles recorded on a recording medium, the method comprising:

reproducing a navigation file including navigation management information indicating a playlist file separate from the navigation file, the navigation management information indicating whether a title search is permitted or prohibited for a title managed by the navigation management information;

reproducing the playlist file indicated by the navigation management information from the recording medium, the playlist file including at least one playitem identifying a playing interval of a clip of the video data; and

reproducing a stream file including the video data from a data area of the recording medium, the stream file being separate from the playlist file.

16. The method of claim 10, further comprising:

reproducing the video data from packets of video data stored on the recording medium, wherein at least a portion of the recorded video data packets belonging to different reproduction paths are multiplexed.

17. The method of claim 10, wherein the video data has multiple reproduction paths.

18. The method of claim 10, wherein the video data includes video data for a director'"'"'s cut title and video data for a theatrical title.

11. An apparatus for recording a data structure for managing reproduction of video data having multiple titles on a recording medium, comprising:

a recording unit configured to record data on the recording medium; and

a controller configured to control the recording unit to record,

a stream file including the video data in a data area of the recording medium,

a playlist file including at least one playitem identifying a playing interval of a clip of the video data in a playlist area of the recording medium, the playlist file being separate from the stream file, and

a navigation file, separate from the playlist file, including navigation management information indicating the playlist file, the navigation management information indicating whether a title search is permitted or prohibited for a title managed by the navigation management information.

19. The apparatus of claim 11, wherein the controller is configured to control the recording unit to record the video data as a unit of packets, wherein at least a portion of the recorded video data packets belonging to different reproduction paths are multiplexed.

20. The apparatus of claim 11, wherein the video data has multiple reproduction paths.

21. The apparatus of claim 11, wherein the video data includes video data for a director'"'"'s cut title and video data for a theatrical title.

12. An apparatus for reproducing a data structure for managing reproduction of video data having multiple titles on a recording medium, comprising:

a reproducing unit configured to reproduce data recorded on the recording medium; and

a controller configured to control the reproducing unit to reproduce,

a navigation file including navigation management information indicating a playlist file separate from the navigation file, the navigation management information indicating whether a title search is permitted or prohibited for a title managed by the navigation management information,

the playlist file indicated by the navigation management information from the recording medium, the playlist file including at least one playitem identifying a playing interval of a clip of the video data, and

a stream file including the video data of the recording medium, the stream file being separate from the playlist file.

22. The apparatus of claim 12, wherein the controller is configured to control the reproducing unit to reproduce the video data as a unit of packets, wherein at least a portion of the recorded video data packets belonging to different reproduction paths are multiplexed.

23. The apparatus of claim 12, wherein the video data has multiple reproduction paths.

24. The apparatus of claim 12, wherein the video data includes video data for a director'"'"'s cut title and video data for a theatrical title.
