Abstract

In the data structure for managing reproduction of text subtitle data, a recording area stores at least one subplayitem. The subplayitem identifies more than one clip information file name, and each clip information file named by the subplayitem indicates an associated clip of auxiliary presentation data to reproduce from the recording medium. The auxiliary presentation data in each clip is associated with at least a portion of main presentation data recorded on the recording medium, and the subplayitem indicates a single presentation interval for the associated clips.

Claims

1. A recording medium having a data structure for managing reproduction of auxiliary presentation data, comprising:

a navigation area storing at least one subplayitem, the subplayitem identifying more than one clip information file name, each clip information file named by the subplayitem indicates an associated clip of auxiliary presentation data to reproduce from the recording medium, the auxiliary presentation data in each clip being associated with at least a portion of main presentation data recorded on the recording medium, the subplayitem indicating a single presentation interval for the associated clips.

2. The recording medium of claim 1, wherein the navigation area stores at least one playitem, the playitem indicating at least a portion of the main presentation data to reproduce.

3. The recording medium of claim 2, wherein the playitem identifies a clip information file name that indicates a clip of main presentation data to reproduce.

4. The recording medium of claim 3, wherein the clip information files identified by the subplayitem and the playitem are different.

5. The recording medium of claim 3, wherein the clip of main presentation data is a separate file from the associated clips of auxiliary presentation data.

6. The recording medium of claim 2, wherein the navigation area stores at least one playlist, the playlist including the playitem and the subplayitem.

7. The recording medium of claim 6, wherein the playlist indicates a type of subpath with which the subplayitem is associated.

8. The recording medium of claim 7, wherein the type of subpath is a text subtitle presentation path.

9. The recording medium of claim 1, wherein each clip information file named by the subplayitem indicates a different associated clip of auxiliary presentation data.

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

a data area storing the associated clips.

11. The recording medium of claim 10, wherein at least one of the associated clips stores the auxiliary presentation data as transport packets.

12. A recording medium having a data structure for managing reproduction of auxiliary presentation data, comprising:

a navigation area storing at least one playlist including navigation information for reproducing main presentation data and auxiliary presentation data associated with the main presentation data, the navigation information indicating a type of subpath with which the auxiliary presentation data is associated, the playlist including at least one subplayitem that provides navigation information for reproducing more than one clip of auxiliary presentation data from the recording medium, the subplayitem indicating a single presentation interval for the clips.

13. The recording medium of claim 12, wherein the type of subpath is a text subtitle presentation path.

14. A recording medium having a data structure for managing reproduction of auxiliary presentation data, comprising:

a data area storing separate clips of auxiliary presentation data and at least one separate clip of main presentation data, the auxiliary presentation data being associated with the main presentation data; and

a navigation area storing a subplayitem providing navigation information for reproducing the separate clips of auxiliary presentation data for a same presentation interval, and the navigation area storing a playitem providing navigation information for reproducing the clip of main presentation data.

15. The recording medium of claim 14, wherein

the playitem provides a presentation interval for reproducing the clip of main presentation data;

and

the presentation interval provided by the subplayitem is associated with the presentation interval provided by the playitem.

16. A method of recording a data structure for managing reproduction of auxiliary presentation data on a recording medium, the method comprising:

recording at least one subplayitem on the recording medium, the subplayitem identifying more than one clip information file name, each clip information file named by the subplayitem indicates an associated clip of auxiliary presentation data to reproduce from the recording medium, the auxiliary presentation data in each clip being associated with at least a portion of main presentation data recorded on the recording medium, the subplayitem indicating a single presentation interval for the associated clips.

17. A method of reproducing a data structure for managing reproduction of a auxiliary presentation data from a recording medium, comprising:

reproducing at least one subplayitem from the recording medium, the subplayitem identifying more than one clip information file name, each clip information file named by the subplayitem indicates an associated clip of auxiliary presentation data to reproduce from the recording medium, the auxiliary presentation data in each clip being associated with at least a portion of main presentation data recorded on the recording medium, the subplayitem indicating a single presentation interval for the associated clips.

18. An apparatus for reproducing a data structure for managing reproduction of auxiliary presentation data from a recording medium, comprising:

a pick-up to reproduce at least one subplayitem from the recording medium, the subplayitem identifying more than one clip information file name, each clip information file named by the subplayitem indicates an associated clip of auxiliary presentation data to reproduce from the recording medium, the auxiliary presentation data in each clip being associated with at least a portion of main presentation data recorded on the recording medium, the subplayitem indicating a single presentation interval for the associated clips.
