Abstract
A method and apparatus are described for generating, under the control of a microprocessor, signals for operating a scanning system of a standard television receiver. A plurality of display segments, each containing information at least partially defining one or more object images that may be desired be included in a specified display on the receiver, are stored in a cartridge memory which can also include specific operating instructions for carrying out a particular video game or other function with such display segments. Indicia uniquely associated with each of the display segments are placed in a predetermined order correlated with the order of appearance in the display of those display seqments which are to be included therein. The position of the scan is tracked, and when it approaches a desired location under the display area for a particular segment to be displayed, it responds to the indicia representing such segment by directing delivery to the scanning system of control signals which define the selected display segment. The apparatus includes composers for producing the display for each line, and a FIFO buffer for delivering information defining the line to the scanning system at a regular rate correlated to the scanning rate, irrespective of the time in which such information is made ready for the display.
