Abstract

The data structure includes a navigation area of a computer readable medium storing navigation data associated with a data stream representing a portion of at least one reproduction path. The navigation data includes indication information, and the indication information indicates whether the data stream represents multiple reproduction paths or the data stream represents a single reproduction path. If the indication information indicates the data stream represents multiple reproduction paths, the navigation data includes path number information and an indicator associated with each reproduction path. The path number information identifies a number of the multiple reproduction paths, and each indicator indicates a file associated with the associated one of the multiple reproduction paths.
