ABSTRACT:
A system for controlling a plurality of distinct devices in a theater displaying a projected motion picture or other visual program and having a multichannel sound signal contained on a moving film or other type strip, which system has a memory unit for storing groups of digital control signals for operating the distinct devices, each forming a channel, in a selected manner during a selected portion of the moving strip. This system has means for selecting one of the groups of the digital control signals for a selected portion of the visual program and means independent of the strip for causing the stored digital control signals of the selected group to be outputted in a time sequence corresponding to the selected portion of the visual program. There is provided an improvement wherein the selecting means includes a digital code recorded on the moving strip and the code comprises a constant, repeating synchronization digital code and a unique digital time code corresponding to the selected group of digital control signals to be outputted in a given time sequence by using hardwired counters for processing the selected digital signals.
