Abstract: Character generator for developing a video signal for application to a television receiver to reproduce characters on the tube screen by a dot matrix. The signal representing each character actuates a plurality of gates for horizontal lines which are operated in turn, and each selectively triggers a set of gates associated with the dot positions along the lines which are operated in turn to produce video components which are combined to form the video signal.
