RECORDING MEDIUM HAVING DATA STRUCTURE FOR MANAGING REPRODUCTION OF AUXILIARY PRESENTATION DATA AND RECORDING AND REPRODUCING METHODS AND APPARATUSES

摘要

In the data structure for managing reproduction of text subtitle data, a recording area stores at least one subplayitem. The subplayitem identifies more than one clip information file name, and each clip information file named by the subplayitem indicates an associated clip of text subtitle data to reproduce from the recording medium. The text subtitle data in each clip is associated with at least a portion of main presentation data recorded on the recording medium. The subplayitem indicates a single presentation interval for the associated clips.
