Patent ID: 7760987

Claim:
An optical disc storing an executable data structure for managing reproduction of at least video data having multiple reproduction paths by a reproducing device, comprising: a data area storing a transport stream of at least video data, the transport stream being divided into groups of transport packets, each group of transport packets associated with one of the multiple reproduction paths; and a navigation area storing a first navigation unit and maps, each of the maps associated with one of the multiple reproduction paths and providing presentation time information and an address in the video data for reproducing one of the groups of transport packets associated with the corresponding reproduction path, wherein the first navigation unit includes at least one second navigation unit and controls a reproduction order of the second navigation units, the second navigation unit including an indicator indicating at least one of the maps associated with one of the multiple reproduction paths for reproducing the group of transport packets, the second navigation unit including an identifier for identifying the one reproduction path of the multiple reproduction paths, and wherein the second navigation unit includes path information indicating a number of the multiple reproduction paths associated with the second navigation unit.
