Recording medium having a data structure for managing text subtitles and recording and reproducing methods and apparatuses

摘要

In the data structure for managing text subtitles, a dialog presentation segment includes text subtitle data of each text subtitle for presentation during a presentation time slot. The dialog presentation segment provides a presentation time stamp start time and a presentation time stamp end time defining the presentation time slot such that the presentation time slot does not overlap a presentation time slot of another dialog presentation segment.
