Abstract
An interface circuit for converting a digital signal representing a dot-by-dot color video signal into a NTSC signal compatible with a television antenna input precompensates the digital for limitations in typical NTSC receivers. Various methods and circuits for precompensating the luminance amplitude, chrominance and chrominance amplitude content of the digital signal result in perceivably improved contrast and color purity.
