Visual presentation system employing two or more video disk players for providing as many correlated images

摘要

One or more, normally three, cathode ray tube displays are juxtaposed for simultaneous reproduction of correlated pictorial and literal images, either in continuous motion or in still, from two or more video disk players in which prerecorded video disks are to be loaded replaceably. A programmable system controller controls the operations of the disk players in accordance with a predefined program. As one of the disk players sequentially retrieves the prerecorded pictures from the associated video disk, an address detector circuit detects the successive disk tracks from which the pictures are being retrieved. Constantly informed of the current track address on that disk, the system controller causes the other disk player or players to retrieve desired pictures from preselected tracks on the other video disk or disks loaded therein.
