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.

Dependent claims

A visual presentation system capable of visually presenting successive sets of correlated scenes according to a desired presentation program, said correlated scenes being recorded on a plurality of record media, comprising:

(a) a plurality of playback devices associated one with each record medium for retrieving prerecorded scenes therefrom, each record medium having a multiplicity of record tracks on which the correlated scenes are prerecorded along with addresses individually identifying the record tracks;
(b) a plurality of displays connected to the playback devices for jointly reproducing successive sets of the prerecorded scenes retrieved from the plurality of record media by the playback devices, the plural displays being disposed in juxtaposition;
and
(c) a system controller connected to the playback devices and having a memory for storing a presentation program, the presentation program including the addresses of desired record tracks on each record medium from which the prerecorded scenes are to be retrieved by one associated device in a desired sequence, the system controller reading the presentation program on the memory for controlling the playback devices according to the presentation program so as to cause each playback device to retrieve the prerecorded scenes from the desired record tracks on one associated record medium in the desired sequence;
wherein the presentation program has a series of steps, each step representing addresses and playback commands for one set of correlated scenes jointly reproduced on the displays, wherein the presentation program written on the memory includes data representing moments of time when the successive steps of the presentation program are to be started, and wherein the visual presentation system further comprises a timer connected to the system controller for providing a time signal, the system controller including means responsive to the time signal to read the successive steps of the presentation program on the memory at the moments of time specified by the presentation program;
and further comprising:
switching means for connecting each playback device to any of the displays;
a monitor display connected to the system controller for visually reproducing the presentation program on the memory;
and input means connected to the system controller for rewriting the presentation program on the memory.
