Recording medium having a data structure for managing reproduction of text subtitle data and methods and apparatuses associated therewith

摘要

A recording area of an example recording medium stores a text subtitle stream that includes a dialog style segment and at least one dialog presentation segment associated with the dialog style segment. The dialog style segment includes at least one set of style information. Each set of style information provides region positioning information for positioning a region in an image and text box positioning information for positioning a text box in the region. The dialog presentation segment includes at least one region subtitle information. The region subtitle information includes text subtitle data (e.g., style data and/or text string data) and a region style identifier, and the region style identifier identifies one of the sets of style information in the dialog style segment to apply to the text subtitle data.
