Abstract: This paper discusses some of the problems involved in the consideration of suitable standards now before the National Television Systems Committee. Resolution is approached from a standpoint of the number of lines and fields within the limits of presently assigned channels. Related problems touched upon are flicker frequency vs. illumination, and some of the difficulties which must be guarded against with colored images such as rainbow effects and flicker, both of which can be minimized by using relatively high frame frequencies. The effects of motion, which tend to smear detail, are discussed in relation to frame and field frequency. The major limitations of present scanning spot shape and intensity distribution, which determine the vertical and horizontal widths of confusion, have been removed in the laboratory, introducing the possiblity of markedly improved definition with a given number of lines and fields, which must be reckoned with in determining standards.
