Recording medium, method, and apparatus for reproducing text subtitle streams

A recording medium and a method and an apparatus for reproducing a text subtitle stream are provided to record the text subtitle stream in the recording medium or efficiently reproduce the recorded text subtitle stream. A text subtitle processor(421) included in a text subtitle decoder(42) divides the text subtitle stream into composition information, rendering information and dialog text. The divided composition information and rendering information are stored in a dialog composition buffer(425) and the divided dialog text data are stored in a dialog buffer(422). The pallet update information is included within the composition information divided by a parsing process. At the rendering process, the divided dialog text data are converted into bit map data by means of the rendering information.
