Abstract

The recording medium includes a navigation area and at least one playlist area. The navigation area stores navigation management information for managing the reproduction of at least multiple reproduction path video data from the recording medium. At least one playlist is stored in a playlist area. Each playlist identifies at least one playitem, and each playitem identifies at least one clip of video data.

Claims

1. A recording medium having a data structure for managing reproduction of at least multiple reproduction path video data recorded on the recording medium, comprising:

at least one navigation area storing navigation management information for managing reproduction of the multiple reproduction path video data recorded on the recording medium; and

at least one playlist area associated with each navigation area, the playlist area storing at least one playlist file associated with each reproduction path, each playlist file identifying at least one playitem, each playitem identifying at least one clip of the multiple reproduction path video data.

2. The recording medium of claim 1, wherein the playlist area stores a single playlist file associated with each reproduction path.

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

4. The recording medium of claim 1, wherein each playlist file is associated with a different reproduction path.

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

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

7. The recording medium of claim 1, wherein at least one clip represents video data for only one reproduction path.

8. The recording medium of claim 1, wherein the navigation management information identifies a reproduction path and at least one playlist associated with the identified reproduction path.

9. The recording medium of claim 1, wherein the multiple reproduction path video data are packets of video data.

10. The recording medium of claim 9, 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.

11. The recording medium of claim 1, wherein the navigation management information identifies a single playlist for each reproduction path.

12. The recording medium of claim 1, wherein the multiple reproduction paths include reproduction paths for different language versions of a title.

13. 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 for managing reproduction of the multiple reproduction path video data in at least one navigation area of the recording medium; and

recording at least one playlist file associated with each reproduction path in at least one playlist area associated with the navigation area, each playlist file identifying at least one playitem, each playitem identifying at least one clip of the multiple reproduction path video data.

14. 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 for managing reproduction of the multiple reproduction path video data from at least one navigation area of the recording medium; and

reproducing at least one playlist file associated with each reproduction path from at least one playlist area associated with the navigation area, each playlist file identifying at least one playitem, each playitem identifying at least one clip of the multiple reproduction path video data.

15. 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 for managing reproduction of the multiple reproduction path video data in at least one navigation area of the recording medium; and

the controller for controlling the driver to record at least one playlist file associated with each reproduction path in at least one playlist area associated with the navigation area, each playlist file identifying at least one playitem, each playitem identifying at least one clip of the multiple reproduction path video data.

16. 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 for managing reproduction of the multiple reproduction path video data from at least one navigation area of the recording medium; and

the controller for controlling the driver to reproduce at least one playlist file associated with each reproduction path from at least one playlist area associated with the navigation area, each playlist file identifying at least one playitem, each playitem identifying at least one clip of the multiple reproduction path video data.
