ABSTRACT:
A one-dimensional memory storage device, such as a video disc, is utilized to store graphic image symbols for video game displays. The storage device is organized so that the graphic symbols may be retrieved rapidly enough to give the visual impression that the entire display, including background or scene depiction, is changing in response to the player-manipulated controls. The memory organization scheme utilized establishes a plurality of jump sequences. The particular sequence being utilized to withdraw graphic symbol information from memory is determined by the physical movement of a player-operated control device, i.e., a joystick. Certain frequently used scenes, such as explosions, or bullet or rocket trajectories, for example, are generated separately by a fixed image producer. The graphic image symbols that reproduce such a scene on the CRT screen are stored in a memory in the fixed image producer which is triggered by the information contained on the video disc or by a player-manipulated control device, such as a pushbutton, for example.
