FIELD: reduction of noise in system coding videosignal. SUBSTANCE: device for compression of videosignal includes unit for generation of residual signals presenting difference in values of image elements, between predicted and real values of image elements, of present frame of videosignal. Noise abating circuits come in the form of non-linear processing element and attenuate low-amplitude residual signals in larger degree than high-amplitude residual signals and respond to evaluation of noise. Processed residual signals are converted to secure output of compressed videodata. Open non-linear functions of processing abate noise and diminish distortion of image. EFFECT: abated noise in processing and compression of videosignal. 21 cl, 7 dwg
