Abstract

A recording medium and method and apparatus for reproducing and recording text subtitle streams are disclosed. The text subtitle stream includes a dialog style segment defining a set of region styles and at least one dialog presentation segment. Each dialog style segment contains at least one region of dialog text, where each region of dialog text includes link information configured to link each region of dialog text to one of the set of region styles defined in the dialog style segment. For example, the link information is a region style identification which uniquely identifies the region style linked to each region of dialog text. When each region of dialog text is reproduced, the region style identified by the region style identification is applied.

Claims

1. A recording medium for storing a data structure, the data structure comprising:

at least one text subtitle stream, each text subtitle stream including style segment defining region styles and at least one presentation segment, the presentation segment containing two regions, each of the two regions including independent link information configured to link the corresponding region to distinct region style defined in the style segment.

2. The recording medium of claim 1, wherein the link information is region style identification specifying the region style linked to each region.

3. The recording medium of claim 1, wherein the region further includes at least one text string and defines an inline style for each text string, the inline style being applied to at least a portion of each text string.

4. The recording medium of claim 1, wherein the region style comprises a plurality of display properties including font-related display properties required for displaying text data in the text subtitle stream.

5. The recording medium of claim 4, wherein the plurality of display properties include at least one of a region position, a region size, a region background color, a text position, a text flow, a text alignment, a line space, a font identification, a font style, a font size, and a font color.

6. The recording medium of claim 5, wherein the region position specifies at least one of a horizontal position and a vertical position of the region within the display screen.

7. The recording medium of claim 5, wherein the region size specifies at least one of a width and height of the region.

8. The recording medium of claim 5, wherein the text flow specifies at least one of a character progression and a line progression of the text data within the region.

9. The recording medium of claim 8, wherein the text flows corresponding to each of the regions have the same value.

10. The method of claim 1, wherein each presentation segment further contains presentation time information indicating presentation start and end times of the two regions.

11. A method for reproducing text subtitle streams, the method comprising:

decoding a text subtitle stream, each text subtitle stream including a style segment defining region styles and a plurality of presentation segments, at least one presentation segment containing two regions, each of the two regions including independent link information configured to link the corresponding region to distinct region style defined in the style segment.

12. The method of claim 11, wherein each presentation segment further contains presentation time information indicating presentation start and end times of the two regions.

13. The method of claim 11, wherein the link information is region style identification specifying the region style linked to each region.

14. The method of claim 11, wherein the region further includes at least one text string and defines an inline style for each text string, the inline style being applied to at least a portion of each text string.

15. The method of claim 11, wherein the region style comprises a plurality of display properties including font-related display properties required for displaying text data in the text subtitle stream.

16. The method of claim 15, wherein the text flow specifies at least one of a character progression and a line progression of the text data within the region.

17. The method of claim 16, wherein the text flows corresponding to each of the two regions have the same value.

18. A method of recording text subtitle streams, the method comprising:

generating style segment defining region styles and at least one presentation segment containing two regions, each of the two regions including independent link information configured to link the corresponding region to distinct region style defined in the style segment;

generating at least one text subtitle stream including the style segment and the presentation segment; and

storing the at least one text subtitle stream on a storing device.

19. The method of claim 18, wherein each presentation segment further contains presentation time information indicating presentation start and end times of the two regions.

20. The method of claim 18, wherein the link information is region style identification specifying the region style linked to each region.

21. The method of claim 18, wherein the region further includes at least one text string and defines an inline style for each text string, the inline style being applied to at least a portion of each text string.

22. The method of claim 18, wherein the region style comprises a plurality of display properties including font-related display properties required for displaying text data in the text subtitle stream.

23. The method of claim 22, wherein the text flow specifies at least one of a character progression and a line progression of the text data within the region.

24. The method of claim 23, wherein the text flows corresponding to each of the two regions have the same value.

25. A method of generating text subtitle streams, the method comprising:

generating style segment defining region styles and at least one presentation segment containing two regions, each of the two regions including independent link information configured to link the corresponding region to distinct region style defined in the style segment; and

generating at least one text subtitle stream including the style segment and the presentation segment.

26. The method of claim 25, the method further comprising:

storing the at least one text subtitle stream on a storage device.

27. An apparatus for reproducing text subtitle streams, the apparatus comprising:

a driver configured to read a data, wherein the data includes a text subtitle stream, each text subtitle stream including a style segment defining region styles and a plurality of presentation segments, at least one presentation segment containing two regions, each of the two regions including independent link information configured to link the corresponding region to distinct region style defined in the style segment.

28. The apparatus of claim 27, wherein each presentation segment further contains presentation time information indicating presentation start and end times of the two regions.

29. The apparatus of claim 27, wherein the link information is region style identification specifying the region style linked to each region.

30. The apparatus of claim 27, wherein the region further includes at least one text string and defines an inline style for each text string, the inline style being applied to at least a portion of each text string.

31. The apparatus of claim 27, wherein the region style comprises a plurality of display properties including font-related display properties required for displaying text data in the text subtitle stream.

32. The apparatus of claim 31, wherein the text flow specifies at least one of a character progression and a line progression of the text data within the region.

33. The apparatus of claim 32, wherein the text flows corresponding to each of the two regions have the same value.

34. An apparatus for reproducing text subtitle streams, the apparatus comprising:

a decoder configured to decode at least one text subtitle, each text subtitle stream including a style segment defining region styles and a plurality of presentation segments, at least one presentation segment containing two regions, each of the two regions including independent link information configured to link the corresponding region to distinct region style defined in the style segment; and
