Abstract: In a standard NTSC composite video signal, the peak excursion of the luminance plus chrominance signal for certain saturated colors exceeds the peak excursion of the white-representative luminance alone. When digitized, the signal is subject to quantizing noise. The effective spectial distribution of the quantizing noise is improved by reducing the amplitude of the chrominance signal so that the peak excursion of luminance plus chrominance for saturated colors does not substantially exceed the peak amplitude of white-representative luminance.

Abstract: A dropout compensator for temporally distributed digital television signals uses either a horizontal averaging or a vertical averaging to replace a missing sampled value. The choice of direction depends on the direction in which the smallest change about the missing sampled value or the missing picture element occurs. The circuit may also be used for colour inversion if a still or slow-motion representation is to be transmitted or recorded.
