Abstract

The recording area of ​​the exemplary recording medium stores a text subtitle stream including dialogue style segments and at least one dialogue visualization segment associated with the dialogue type segments. A 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 the image and text box positioning information for positioning a text box in the region. The dialog display segment includes at least one region subtitle information. The regional subtitle information includes text subtitle data (eg, style data and / or text string data) and a region style identifier, and the region style identifier identifies one of the style information groups in the dialog style segment to be applied to the text subtitle data.

Description

[0001] This application is filed on May 2, 2005, with an application number of PCT / KR2005 / 001260, entitled "Recording medium having a data structure for managing reproduction of text subtitle data and related methods and devices" Divisional application. technical field [0002] The present invention relates to a recording medium and a method and apparatus for recording and reproducing the recording medium. Background technique [0003] Optical discs have been widely used as optical recording media for recording large amounts of data. Recently, a blu-ray disc (BD) has been introduced as a high-density digital video disc (HD-DVD) for recording many hours of high-definition video data and audio data of excellent sound quality. [0004] BD has become the focus of next-generation HD-DVD as a next-generation optical recording solution to store more data than traditional DVD. BD's standardized technical specifications are under development. [0005] Therefore, based on the speci...
