ABSTRACT:
Noise reduction circuitry, in a video signal compression apparatus of the predictive DPCM compression type includes a simple nonlinear processing element within the DPCM loop to eliminate residues between predicted and real image signals, which are smaller than a predetermined value. Elimination of such residues dramatically reduces the amount of compressed data generated for signals including even modest amounts of noise.
