Abstract: The present invention relates to an improved data converter system that will accept the 3-D definition or description of a geometric object or symbol and convert it into a form suitable for display on a 2-D display device.Once a symbol has been defined, it may be manipulated in several ways, a few of which are rotation of the symbol and moving the symbol from one location to another. Special effects may also be performed on the symbols on display, some of which include fade-in, fade-out and zoom. The data converter system also includes a video distributor that makes it possible to display the resulting picture of the symbols on a plurality of display devices each adapted to show part or all of the picture.

Abstract: A television game system is provided wherein a modular unit may be connected to a standard television receiver for the generation, display and control of symbols or geometric figures on the television screen to allow one or several players to participate in a game in which the action is presented on the screen. The modular unit is programmable whereby several different games may be played selectively with the same unit, allowing flexibility in the range of operation of the unit as well as the television receiver. The level of complexity of the games can be adjusted to each player's ability whereby players of different ability can play each other on a competition basis.
