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 having a data structure for managing reproduction of multiple title video data recorded on the recording medium, comprising:

a navigation area storing navigation management information associated with each title of video data, the navigation management information associated with a title indicating at least one reproduction path for the title and including an attribute field indicating at least one attribute of the navigation management information.

2. The recording medium of claim 1, further comprising:

at least one playlist area storing playlist files, each playlist file identifying at least one playitem, each playitem identifying at least one clip of the multiple title video data.

3. The recording medium of claim 2, wherein each navigation management information associated with a title identifies at least one playlist file to playback during reproduction of the title.

4. The recording medium of claim 3, wherein at least two playitems, each from a different playlist file, identify a same clip.

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

6. The recording medium of claim 3, wherein at least one clip represents video data for only one reproduction path.

7. The recording medium of claim 1, wherein the multiple title video data are packets of video data.

8. The recording medium of claim 1, wherein the video data is multiple reproduction path video data.

9. The recording medium of claim 8, further comprising:

a data area having at least the video data packets recorded therein, and at least a portion of the recorded video data packets belonging to different reproduction paths being multiplexed.

10. The recording medium of claim 1, wherein multiple title video data include video data for a director'"'"'s cut title and video data for a theatrical title.

11. A method of recording a data structure for managing reproduction of at least multiple reproduction path video data on a recording medium, comprising:

recording navigation management information associated with each title of video data in at least one navigation area of the recording medium, the navigation management information associated with a title indicating at least one reproduction path for the title and including an attribute filed indicating at least one attribute of the navigation management information.

12. A method of reproducing a data structure for managing reproduction of at least multiple reproduction path video data recorded on a recording medium, comprising:

reproducing navigation management information associated with each title of video data from at least one navigation area of the recording medium, the navigation management information associated with a title indicating at least one reproduction path for the title and including an attribute filed indicating at least one attribute of the navigation management information.

13. An apparatus for recording a data structure for managing reproduction of at least multiple reproduction path video data on a recording medium, comprising:

a driver for driving an optical recording device to record data on the recording medium;

an encoder for encoding at least multiple reproduction path video data; and

a controller for controlling the driver to record the encoded multiple reproduction path video data on the recording medium, the controller for controlling the driver to record navigation management information associated with each title of video data in at least one navigation area of the recording medium, the navigation management information associated with a title indicating at least one reproduction path for the title and including an attribute filed indicating at least one attribute of the navigation management information.

14. An apparatus for reproducing a data structure for managing reproduction of at least multiple reproduction path video data recorded on a recording medium, comprising:

a driver for driving an optical reproducing device to reproduce data recorded on the recording medium;

a controller for controlling the driver to reproduce navigation management information associated with each title of video data from at least one navigation area of the recording medium, the navigation management information associated with a title indicating at least one reproduction path for the title and including an attribute filed indicating at least one attribute of the navigation management information.
