A recording medium and method and apparatus for reproducing and recording text subtitle streams are disclosed. The text subtitle stream includes a dialog style segment defining a set of region styles and at least one dialog presentation segment. Each dialog style segment contains at least one region of dialog text, where each region of dialog text includes link information configured to link each region of dialog text to one of the set of region styles defined in the dialog style segment. For example, the link information is a region style identification which uniquely identifies the region style linked to each region of dialog text. When each region of dialog text is reproduced, the region style identified by the region style identification is applied.
