Recording medium having data structure for managing reproduction of data streams recorded thereon and recording and reproducing methods and apparatuses
First Claim
1. A computer readable recording medium having a data structure for managing reproduction of a data stream, comprising:
- a navigation area storing navigation data associated with at least one data stream of at least one reproduction path, the navigation data including first and second indication information, the first indication information indicating whether the navigation data is associated with the data streams of multiple reproduction paths or the navigation data is associated with the data stream of a single reproduction path, and if the first indication information indicates the navigation data is associated with the data streams of the multiple reproduction paths, the second indication information indicates whether or not the data streams of the multiple reproduction paths are associated with seamless reproduction.

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.
