Abstract

In the data structure for managing data streams associated with different languages, a playlist including at least one playitem for managing reproduction of a main data stream is provided. The playitem includes a table defining a list of data streams. The list of data streams includes the main data stream and a data stream of at least one type of supplemental data stream. The table includes language information on each supplemental data stream of the type of supplemental data stream, and the language information indicates a language associated with the supplemental data stream.

Claims

1. A recording medium having a data structure for managing data streams associated with different languages, comprising:

a recording area recording a playlist, the playlist including at least one playitem for managing reproduction of a main data stream, the playitem including a table defining a list of data streams including the main data stream and at least one type of supplemental data stream, the table including language information on each supplemental data stream of the type of supplemental data stream, the language information indicating a language associated with the supplemental data stream.

2. The recording medium of claim 1, wherein the type of supplemental data stream is text subtitles.

3. The recording medium of claim 1, wherein the type of supplemental data stream is interactive graphics.

4. The recording medium of claim 1, wherein the type of supplemental data stream is presentation graphics.

5. The recording medium of claim 1, wherein the table includes a type indicator for each data stream indicating whether the data stream is a main or supplemental data stream.

6. The recording medium of claim 1, wherein the table includes a type indicator for each data stream indicating whether the data stream is used by the playitem or a subpath of the playitem.

7. The recording medium of claim 1, wherein the table includes a type indicator for each data stream indicating whether the data stream is used by the playitem or a subplayitem.

8. The recording medium of claim 1, wherein the language information is a language code.

9. The recording medium of claim 1, wherein the table includes a data structure for each data stream, the data structure includes a type indicator indicating whether the data stream is used by the playitem or a subpath of the playitem, and when the type indicator indicates the data stream is used by a subpath, the data structure includes the language information.

10. The recording medium of claim 1, wherein the language information is a language code.

11. The recording medium of claim 1, wherein the table includes at least one data structure for each data stream, each data structure including a field that indicates a packet identifier of transport packets forming the data stream.

12. The recording medium of claim 1, wherein the table includes at least one data structure for each data stream, each data structure for a supplemental data stream including a field that indicates a subpath identifier of a subpath to which the supplemental data stream belongs.

13. A method of reproducing a data structure for managing data streams associated with different languages from a recording medium, comprising:

reproducing a playlist from the recording medium, the playlist including at least one playitem for managing reproduction of a main data stream, the playitem including a table defining a list of data streams including the main data stream and at least one type of supplemental data stream, the table including language information on each supplemental data stream of the type of supplemental data stream, the language information indicating a language associated with the supplemental data stream.

14. The method of claim 13, further comprising:

selectively reproducing a supplemental data stream based on the language information and input received from a user.

15. A method of recording a data structure for managing data streams associated with different languages on a recording medium, comprising:

recording a playlist on the recording medium, the playlist including at least one playitem for managing reproduction of a main data stream, the playitem including a table defining a list of data streams including the main data stream and at least one type of supplemental data stream, the table including language information on each supplemental data stream of the type of supplemental data stream, the language information indicating a language associated with the supplemental data stream.

16. An apparatus for reproducing a data structure for managing data streams associated with different languages from a recording medium, comprising:

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

a controller for controlling the driver to reproduce a playlist from the recording medium, the playlist including at least one playitem for managing reproduction of a main data stream, the playitem including a table defining a list of data streams including the main data stream and at least one type of supplemental data stream, the table including language information on each supplemental data stream of the type of supplemental data stream, the language information indicating a language associated with the supplemental data stream.

17. The method of claim 16, wherein the controller controls the driver to selectively reproduce a supplemental data stream based on the language information and input received from a user.

18. An apparatus for recording a data structure for managing data streams associated with different languages on a recording medium, comprising:

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

a controller for controlling the driver to record a playlist on the recording medium, the playlist including at least one playitem for managing reproduction of a main data stream, the playitem including a table defining a list of data streams including the main data stream and at least one type of supplemental data stream, the table including language information on each supplemental data stream of the type of supplemental data stream, the language information indicating a language associated with the supplemental data stream.

19. A recording medium having a data structure for managing data streams associated with different languages, comprising:

a recording area recording a clip information file, the clip information file including at least a program information data structure, the program information data structure providing stream coding information for each data stream, the stream coding information for at least one of the data streams including language information indicating a language associated with the data stream.

20. The recording medium of claim 19, wherein the stream coding information for each data stream includes a type indicator indicating the type of data stream.

21. The recording medium of claim 20, wherein when the type indicator indicates a text subtitle data stream, the coding information includes the language information.

22. The recording medium of claim 21, wherein the language information is a language code.

23. The recording medium of claim 19, wherein the language information is a language code.
