Abstract

PURPOSE: Luminance signal components is forecasted by the luminance signal components of a scanning line and the luminance components of the preceding scanning line, and the forecasting value of NTSC signals is synthesized by adding this forecast and the chrominance signal components of the preceding scanning line, thereby compressing a band effectively.
