Abstract
A PAL digital video signal processing arrangement includes converter circuitry for sampling a system video signal in response to sampling pulses having sampling points associated with .+-.U and .+-.V modulation axes on a color vector plane to convert an analog composite video signal containing a luminance signal and a color subcarrier into a digital video signal, and a modulation axis inverting configuration for inverting the polarity of the digitized color subcarrier at the sampling points associated with the .+-.V axis.
