Abstract

The recording medium includes a navigation area storing navigation control information for managing the reproduction of at least video data from the recording medium. The navigation area, according to one embodiment, stores at least one navigation control object that includes an attribute field indicating at least one attribute of the navigation control object and a navigation direction number field indicating a number of navigation directions. Each navigation control object includes at least one navigation direction.

Claims

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

at least one navigation area storing at least one navigation control object, each navigation control object having an attribute field indicating at least one attribute of the navigation control object and at least one navigation item providing navigation control information.

2. The recording medium of claim 1, wherein the navigation item identifies at least one playlist to reproduce.

3. The recording medium of claim 2, wherein the navigation item identifies a single playlist associated with one reproduction path to reproduce.

4. The recording medium of claim 1, wherein the navigation control object is associated with a single title of video data.

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

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

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

at least one navigation area storing at least one navigation control object, each navigation control object associated with a single title of video data, each navigation control object having an attribute field indicating at least one attribute of the navigation control object and a navigation number field indicating a number of navigation items, each navigation control object including at least one navigation item and the navigation item providing navigation control information.

7. The recording medium of claim 6, wherein the navigation item identifies at least one playlist to reproduce.

8. The recording medium of claim 7, wherein the navigation item identifies a single playlist associated with one reproduction path to reproduce.

9. The recording medium of claim 6, further comprising:

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

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

at least one navigation area storing at least one navigation control object, each navigation control object having an attribute field indicating at least one attribute of the navigation control object, the navigation control object including at least one navigation direction.

11. The recording medium of claim 10, wherein the navigation direction identifies at least one playlist to reproduce.

12. The recording medium of claim 11, wherein the navigation direction identifies a single playlist associated with one reproduction path to reproduce.
