ABSTRACT:
An interactive video system has a videodisc player, a joystick, a framestore, a display, and a control device for controlling functions such as reading of frames from the framestore to the display. The videodisc player stores several sequences of moving pictures with the frames of the sequences interleaved so that changes can quickly be made from one sequence to another. To mask the reduced frame rate of any one sequence, repeated frames from the framestore are given a alternate blue and red color casts. To give the effect of changing perspectives with motion, the portion of the framestore read to the display changes in dependence upon (ii) the joystick output and (ii) the existing location of the displayed portion in the framestore.
