Abstract

The present invention provides a recording medium, reproducing method thereof and reproducing apparatus thereof. The present invention includes a text subtitle stream including at least one dialog presentation segment (DPS) and one dialog style segment (DSS) and a clipinfo file (*,clpi) as reproduction management information to reproduce the text subtitle stream, wherein map information mapped to a dialog presentation segment (DPS) within the text subtitle stream is recorded in the clipinfo file.

Claims

1. A recording medium, comprising:

a main data stream;

a text subtitle stream including at least one dialog presentation segment (DPS) and one dialog style segment (DSS) for use with the main data stream, each of the dialog presentation segments (DPSs) defining at least one region; and

information files including management information for managing reproduction of the main data stream and the text subtitle stream, respectively,

wherein the management information includes map information mapping time information to address information for the main data stream, and the dialog presentation segment (DPS) includes text strings and inline style information for a portion of the region, and the dialog style segment (DSS) includes region style information for all of the region defined in the dialog presentation segment (DPS), the dialog presentation segment (DPS) referencing the region style information defined in the dialog style segment (DSS) using an identifier.

2. The recording medium of claim 1, wherein the management information includes language information for the text subtitle stream.

3. The recording medium of claim 1, wherein the management information includes font information for the text subtitle stream.

4. The recording medium of claim 1, wherein the map information includes coarse map information and fine map information.

5. The recording medium of claim 1, wherein the information files include an information file for each text subtitle stream.

6. A method of reproducing a main data stream and a text subtitle stream recorded on a recording medium, the reproducing method comprising:

reading management information from management files for reproducing the main data stream and the text subtitle stream, the text subtitle stream including at least one dialog presentation segment (DPS) and one dialog style segment (DSS), respectively, each of the dialog presentation segments (DPSs) defining at least one region; and

reproducing the main data stream and the text subtitle stream using the management information,

wherein the management information includes map information mapping time information to address information for the main data stream, and the dialog presentation segment (DPS) includes text strings and inline style information for a portion of the region, and the dialog style segment (DSS) includes region style information for all of the region defined in the dialog presentation segment (DPS), the dialog presentation segment (DPS) referencing the region style information defined in the dialog style segment (DSS) using an identifier.

7. The method of claim 6, wherein the management information includes language information for the text subtitle stream.

8. The method of claim 6, wherein the management information includes font information for the text subtitle stream.

9. The method of claim 6, wherein the map information includes coarse map information and fine map information.

10. The method of claim 6, wherein the management files include an information file for each text subtitle stream.

11. A method of recording data streams, comprising:

operating a recording apparatus to record a main data stream and a text subtitle stream, the text subtitle stream including at least one dialog presentation segment (DPS) and one dialog style segment (DSS) for use with the main data stream, each of the dialog presentation segments (DPS)s defining at least one region; and

recording information files including management information for reproducing the main data stream and the text subtitle stream, respectively,

wherein the management information includes map information mapping time information to address information for the main data stream, and the dialog presentation segment (DPS) includes text strings and inline style information for a portion of the region, and the dialog style segment (DSS) includes region style information for all of the region defined in the dialog presentation segment (DPS), the dialog presentation segment (DPS) referencing the region style information defined in the dialog style segment (DSS) using an identifier.

12. The method of claim 11, wherein the management information includes language information for the text subtitle stream.

13. The method of claim 11, wherein the management information includes font information for the text subtitle stream.

14. The method of claim 11, wherein the map information includes coarse map information and fine map information.

15. The method of claim 11, wherein the information files include an information file for each text subtitle stream.

16. An apparatus for reproducing data streams, comprising:

a pickup configured to read data streams recorded on a recording medium;

a controller configured to control the pickup to read a main data stream and a text subtitle stream, the text subtitle stream including at least one dialog presentation segment (DPS) and one dialog style segment (DSS) utilized with the main data stream, and an information file including management information for reproducing the main data stream and the text subtitle stream, respectively, each of the dialog presentation segments (DPSs) defining at least one region,
