Abstract

Embodiments disclosed allow assigning programs for presentation in a digital cinema system. In one embodiment, a scheduler 180 is implemented to generate a schedule in accordance to which decoding modules 140 control playback of data for presentation in the digital cinema systems. The decoding module 140 may operate in an automatic mode and/or manual mode. In automatic mode, the decoding module 140 controls playback based on the schedule, without user intervention. In manual mode, the decoding module 140 cues the user at the appropriate times to control playback based on the schedule.
