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.
In a video game having a color game display monitor; permanent memory means for the storage of color game symbols; a first source of picture information comprising a temporary screen memory means, including game symbols, to be displayed on the monitor; a game processor adapted to control game play and to transfer game symbols from the permanent memory means to the screen memory means and to reposition symbols therein; color translator means programmable by the game processor, said translator means operatively connected to the permanent and screen memory means whereby one or more of the colors of the game symbols retained in the memory means may altered by the translator as the symbol is written to the screen memory means.

The video game of claim 1 including a video disk or other second source of video picture information for display on the monitor; switch means for selecting the video information for display on the monitor from the first screen memory means or the second video source; video switch control means operatively connected to the switch means, said control means being responsive to one or more predetermined color codes from the screen memory source whereby the the video picture information from the screen memory source is displayed unless the video information therefrom comprises one of said predetermined color codes, in such event the video information from the second video source is display on the monitor.
