CIRCUIT ARRANGEMENT FOR PROCESSING A VIDEO SIGNAL, INCLUDING MEANS FOR AVOIDING A VERTICAL COLOR SHIFT AT HORIZONTAL COLOR TRANSITIONS

摘要

A video recorder (1), or a circuit arrangement (5) for a video recorder (1), includes filter means (24) for performing a com-filtering operation and supplying a comb-filtered component (C) of a video signal, and also includes controllable influencing means (35) for terminating the output of the comb-filtered component (C) and for activating instead the propagation of the non-filtered component (C), and transition detection means (39) for detecting a vertically extending transition and supplying characteristic information (KI) upon detection of such a transition, control information generating means (49) being arranged between the transition detection means (39) and the influencing means (35), which control information generating means can generate control information (SI) enabling the termination of the output of the comb-filtered component (C) and the activation of the propagation of the non-filtered component (C) instead for a period of time which is longer than possible by means of the characteristic information (KI).
