Abstract
In the a data structure, a subtitle area of the recording medium stores a text subtitle stream including text subtitle data and at least one of global style information and local style information. The global style information provides at least one of composition information and rendering information, and the local style information provides font information for at least a portion of the text subtitle data.
Claims22
An optical disc, comprising:
- an area storing a text subtitle stream including at least a first segment and a second segment, the first segment including first style information and the second segment including text subtitle data and second style information,
- wherein the second segment is linked to the first segment, the first style information includes at least one of composition information and rendering information for a region including the text subtitle data, and the second style information includes font information for the text subtitle data,
- wherein the font information is declared at a beginning of at least a portion of the text subtitle data affected by the font information,
- wherein the second segment includes a length indicator indicating a length of the at least the portion of the text subtitle data, and
- wherein each of the first segment and the second segment includes a segment identifier identifying the first segment and the second segment, respectively.
