Abstract:
1. A computer readable medium having a data structure for managing reproduction of a data stream, comprising: a navigation area for storing navigation data associated with the data stream representing a portion of at least one reproduction path, the navigation data including data of minimum extent size and indication information, the indication information for indicating whether the data stream represents multiple reproduction paths or the data stream represents a single reproduction path, and the navigation data includes path number information and an indicator associated with each reproduction path, the path number information for identifying path numbers respectively of the multiple reproduction paths, and the indicator for indicating a file associated with the associated one of the multiple reproduction paths, wherein, when the indication information indicates the data stream represents multiple reproduction paths, the navigation data includes entry points of a plurality of audio or video streams, as the data stream, respectively forming the multiple reproduction paths and reproduction path change points set based on the entry points, wherein each of the reproduction change points has a flag indicating whether the entry point is an angle switchable point, such that during reproduction transition at the reproduction path change point, when the reproduction change point has the flag indicating the entry point is the angle switchable point and also when the reproduction change point has the flag indicating the entry point is not the angle switchable point, is seamless by reference to the data of minimum extent size.
