ABSTRACT:
An interactive video disc system employs discs in which video presentations are arranged in parallel in a single spiralled track by being arranged in adjacent turns, or portions of turns, of the spiral. Additional capacity for interaction is achieved by the use of multiple heads and switching from one presentation to another during the formation of picture lines. Different scenes of video information are arranged in an interleaved format on the disc. This format permits special effects involving superimposition of the different scene data to obtain a combined smooth flowing scene without any disturbance in display of the combined scene.
