    • A recording medium, method, and apparatus for reproducing text subtitle streams are disclosed. A microcomputer initially reads a set of PlayItems and a SubPlayItem included in a PlayList which is recorded on a recording medium, and it further reads synchronization information included in the SubPlayItem. Each PlayItem is configured to reproduce at least one main AV stream, and the SubPlayItem is configured to reproduce a text subtitle stream. The synchronization information indicates a presentation start time of the SubPlayItem on a global time axis of the PlayList. When the PlayList is randomly accessed at a random access time on the global time axis, the microcomputer calculates a corresponding access time on a time axis of the SubPlayItem. Then a text subtitle decoder decodes for presentation a dialog presentation segment with the closest dialog start time after the corresponding access time on the axis of the SubPlayItem.
    • 公开了用于再现文本字幕流的记录介质,方法和装置。 微型计算机最初读取记录在记录介质上的播放列表中包括的一组播放项目和子播放项目,并且还读取包含在子播放项目中的同步信息。 每个PlayItem被配置为再现至少一个主AV流,并且SubPlayItem被配置为再现文本字幕流。 同步信息指示在播放列表的全局时间轴上的SubPlayItem的呈现开始时间。 当在全局时间轴上的随机访问时间随机访问播放列表时,微计算机在SubPlayItem的时间轴上计算相应的访问时间。 然后,文本字幕解码器解码以在SubPlayItem的轴上的相应访问时间之后呈现具有最接近的对话开始时间的对话呈现片段。
