ABSTRACT:
Television programs schedules and visual time information are displayed by projection of composite images from the frames of a film strip and slides respectively displaced in synchronism on a cyclic basis and unidirectionally advanced at the end of each regular program period under control of a timer. During film frame movement, other visual material may be projected from intermediate slides in synchronism with audio message signals.
