Abstract:
A movie changeover system (20,200,2004,400) capable of providing a real time decision tree movie presentation having a variable movie display content dependent on the viewing audience response to branching choices which occur during the course of the movie. A pair of movie projection devices (22, 24), each having an associated portion of a substantially continuous overall motion picture presentation therefrom, has stored thereon a projectable portion of the overall motion picture presentation content. A changeover shutter mechanism (26) is operatively associated with the pair of projectors (22, 24) for selectively projecting a movie display choice of one of the projectable portions from one of the pair of projectors (22, 24) in a real time continuous movie display presentation with the previous movie display portion in response to a changeover signal. Means for detecting and sampling the audience responses associated with each choice, such as a microphone (32, 34), is provided with the sampled responses corresponding to preferential signal levels. The sampled signal levels are processed (252, 252a, 254, 256, 258, 260, 262, 320f, 322, 324, 452, 416, 418, 36, 38, 264, 402 ) and subsequently compared (40, 266, 440) to determine which of the two levels is greater, with the resultant signal being provided (268, 274, 276, 478) to an output circuit (42, 278, 442) to which the changeover signal is provided.
