Playback device and method for providing functionality based on event information retrieved from a playlist

摘要

Instead of using events stored in the datastream itself, applications can retrieve event information from the playlist on a record carrier such as DVD and blu-disc. By retrieving the event information from the playlist changes in the event information do not require reprocessing of the data stream. In addition the application knows before the start of the playback of the data stream where the events are located and what functionality in terms of resources is required. A better scheduling of resources is thus possible.
