Directions of Improvement in NTSC Color Television Systems

This paper discusses possible directions of improvement in the NTSC color television standards. These are aimed at minor modifications of the transmitted signal which allow the use of simpler color receivers with more accurate resolution in colored areas. Compatibility also appears likely to be improved by one of the features presented, that is, monochrome receivers would display improved picture quality. The modifications are specifically selected to permit color receivers designed for the unmodified standards to display satisfactory pictures, particularly including correct large-area color. Since the system is essentially defined by the nominal form of receiver which reproduces the transmitted picture in accordance with the signal specification (the reference monitor), emphasis is on changes affecting the form of receiver.
