Abstract

In the data structure for managing reproduction of text subtitle data, a text subtitle information area stores at least one text subtitle information segment. The text subtitle information segment is represented by a single PES packet of transport packets. In one embodiment, the text subtitle information segment includes an identifier identifying the text subtitle information segment as a text subtitle information segment and includes style information for text subtitle data.

Claims

1. A non-transitory computer readable medium having an executable data structure for managing reproduction of text subtitle data by a reproducing apparatus, comprising:

an area storing at least one main AV data and a plurality of subtitle information segments, each one of the subtitle information segments being represented by each PES packet of transport packets and having a one-to-one correspondence with each PES packet, the PES packet including a packet identifier for identifying a type of the packet, wherein each one of the subtitle information segments includes a segment identifier identifying the subtitle information segment as one of text data and graphic data,

wherein first subtitle information segment identified as the text data defines first style information including a palette identifier identifying palette information for controlling color attributes of the text data,

wherein second subtitle information segment identified as the text data includes at least one text subtitle region, the text subtitle region including second style information applied to the text data for managing reproduction of the text data by the reproducing device and being linked to the first style information defined in the first subtitle information segment by an identifier,

wherein the graphic data is multiplexed with the main AV data into a file while the text data is separate from the main AV data,

wherein either one of the graphic data or the text data is displayed together with the main AV data.

2. The computer readable medium of claim 1, wherein the second style information indicates at least one of font size, font style and font set for the text data.

3. The computer readable medium of claim 1, wherein the text data is character code data.

4. The computer readable medium of claim 1, wherein the second subtitle information segment identified as the text data includes an indicator of a number of the at least one text subtitle region.

5. A method of recording text subtitle data on a recording medium using a recording apparatus, the method comprising:

recording at least one main AV data and a plurality of subtitle information segments on the recording medium using the recording apparatus, each one of the subtitle information segments being represented by each PES packet of transport packets and having a one-to-one correspondence with each PES packet, the PES packet including a packet identifier for identifying a type of the packet, wherein each one of the subtitle information segments includes a segment identifier identifying the subtitle information segment as one of text data and graphic data,

wherein first subtitle information segment identified as the text data defines first style information including a palette identifier identifying palette information for controlling color attributes of the text data,

wherein second subtitle information segment identified as the text data includes at least one text subtitle region, the text subtitle region including second style information applied to the text data for managing reproduction of the text data by the reproducing device and being linked to the first style information defined in the first subtitle information segment by an identifier,

wherein the graphic data is multiplexed with the main AV data into a file while the text data is separate from the main AV data,

wherein either one of the graphic data or the text data is displayed together with the main AV data.

6. The method of claim 5, wherein the second style information indicates at least one of font size, font style and font set for the text data.

7. The method of claim 5, wherein the text data is character code data.

8. The method of claim 5, wherein the second subtitle information segment identified as the text data includes an indicator of a number of the at least one text subtitle region.

9. A method of reproducing text subtitle data from a recording medium using a reproducing apparatus, comprising:

reproducing at least one main AV data and a plurality of subtitle information segments from the recording medium using the reproducing apparatus,

each one of the subtitle information segments being represented by each PES packet of transport packets and having a one-to-one correspondence with each PES packet, the PES packet including a packet identifier for identifying a type of the packet, wherein each one of the subtitle information segments includes a segment identifier identifying the subtitle information segment as one of text data and graphic data,

wherein first subtitle information segment identified as the text data defines first style information including a palette identifier identifying palette information for controlling color attributes of the text data,

wherein second subtitle information segment identified as the text data includes at least one text subtitle region, the text subtitle region including second style information applied to the text data for managing reproduction of the text data by the reproducing device and being linked to the first style information defined in the first subtitle information segment by an identifier,

wherein the graphic data is multiplexed with the main AV data into a file while the text data is separate from the main AV data,

wherein either one of the graphic data or the text data is displayed together with the main AV data.

10. The method of claim 9, wherein the second style information indicates at least one of font size, font style and font set for the text data.

11. The method of claim 9, wherein the text data is character code data.

12. The method of claim 9, wherein the second subtitle information segment identified as the text data includes an indicator of a number of the at least one text subtitle region.

13. An apparatus for recording text subtitle data on a recording medium, comprising:

a pickup configured to record data on the recording medium; and

a controller configured to control the pickup to record at least one main AV data and a plurality of subtitle information segments on the recording medium,

each one of the subtitle information segments being represented by each PES packet of transport packets and having a one-to-one correspondence with each PES packet, the PES packet including a packet identifier for identifying a type of the packet, wherein each one of the subtitle information segments includes a segment identifier identifying the subtitle information segment as one of text data and graphic data,

wherein first subtitle information segment identified as the text data defines first style information including a palette identifier identifying palette information for controlling color attributes of the text data,

wherein second subtitle information segment identified as the text data includes at least one text subtitle region, the text subtitle region including second style information applied to the text data for managing reproduction of the text data by the reproducing device and being linked to the first style information defined in the first subtitle information segment by an identifier,

wherein the graphic data is multiplexed with the main AV data into a file while the text data is separate from the main AV data,

wherein either one of the graphic data or the text data is displayed together with the main AV data.

14. The apparatus of claim 13, wherein the second style information indicates at least one of font size, font style and font set for the text data.

15. The apparatus of claim 13, wherein the text data is character code data.

16. The apparatus of claim 13, wherein the second subtitle information segment identified as the text data includes an indicator of a number of the at least one text subtitle region.
