Abstract
A microprocessor-based system for controlling the presentation of a motion picture film in a theater having sound, lens, masks, and light systems with controllers for switching between the various modes or settings of the systems. The microprocessor-based system receives, stores and outputs information relating to desired operational settings along with the various times at which these settings are to be adjusted as a function of time relative to the start of the film.
