ABSTRACT:
A multimedia motion picture and photographic slide projection control apparatus which permits a plurality of projector devices to be controlled from an operator's console. Manually operable switch means, operating through digital control means, develops a Program Command Code Word for each change in switch conditions, the control word being decoded to provide an ON/OFF response by selected projectors, as well as lamp dissolve rate response. Simultaneously, the Program Command Code Words are recorded on a magnetic tape such that when a given presentation has been developed to the satisfaction of the operator, the stored command words can be used to control the projection devices to provide repetitive performances of the same audio-visual presentation.
