ABSTRACT:
A video game or the like including a real-time interactive video disk game-play background generation system. The disk player incorporates track skipping capability which is under the direct control of the game processor, on a frame-by-frame basis, whereby substantially instantaneous jumps to alternative video scenes can be effected in response to changing game play. Video scene data is stored on the disk in horizontally compressed format. A video expander/scroller effectively stretches the compressed video from the disk by a factor of two and selects, under game processor control, one frame width, or one-half the expanded background scene, for display. A color programmable read-only-memory (PROM) having at least two pre-programmed color pallets is provided to redefine color relationships of game symbols stored in read-only-memory (ROM) thereby reducing the storage of redundant game symbol data in this ROM.
