Multiple display presentation system capable of sequencing prerecorded

Abstract

A set of displays are juxtaposed for jointly reproducing, either in still or in continuous motion, successive sets of correlated scenes according to a desired, and readily modifiable, presentation program. The correlated scenes to be reproduced by the displays are retrieved by video disk players from a set of video disks each having a multiplicity of individually addressable record tracks. A system controller is provided which has a rewritable memory for storing a presentation program including the addresses of desired record tracks on each video disks from which the prerecorded scenes are to be retrieved by one associated disk player in a desired sequence, and playback commands indicative of whether the prerecorded scenes on the desired record tracks are to be reproduced in still or in continuous motion. The system controller reads the presentation program on the memory for controlling the disk players according to the presentation program, causing each disk player to retrieve the prerecorded scenes from the desired record tracks on one associated video disk in the desired sequence, for reproduction on one of the displays either in still or in continuous motion as dictated by the presentation program. The presentation program is therefore readily modifiable by rewriting on the memory.
