1. A non-transitory recording medium storing an executable data structure for managing reproduction of at least video data having multiple reproduction paths by a reproducing apparatus, comprising:
- a data area storing a transport stream of at least video data, the transport stream being divided into transport packets, the transport packets for one of the multiple reproduction paths being grouped into at least one interleaving unit, and the interleaving units of the multiple reproduction paths being interleaved with one another; and
a navigation area storing a first navigation unit, the first navigation unit including one or more second navigation units and controlling a reproduction order of the second navigation units, at least one second navigation unit referencing a plurality of maps, each map identifying transport packets and entry points in the transport packets associated with one of the reproduction paths, and each map providing relation information between presentation time and transport packets of the associated reproduction path, the at least one second navigation unit including at least one identifier identifying the identity of the associated reproduction path, the first navigation unit being separate from each map.

Abstract
In the data structure, a data area of the recording medium stores a transport stream of at least video data. The transport stream is divided into transport packets. Each of the transport packets is associated with one of the multiple reproduction paths, and the transport packets of each reproduction path are interleaved with one another.
