description A circuit for enhancing chrominance transitions in a received chrominance video signal comprises linear-phase digital filter means (1) supplied with an input stream of discrete chromatic image elements (x(n-6)-x(n)) and having a high-pass transfer characteristic in a region of the frequency spectrum corresponding to an upper limit of a transmitted chrominance signal bandwidth for enhancing high-frequency components of the received chrominance signal (CIN), and non-linear digital post-processing means (2) supplied by an output (FOUT) of the filter means and by said input stream of discrete chromatic image elements, the non-linear post-processing means comprising first means (4) acting on said output of the filter means for eliminating distortions introduced in the received chrominance signal by the filter means and second means (3) for detecting if the received chrominance signal contain a transition pattern corresponding to predetermined patterns and for correspondingly forcing an output (COUT) of the circuit to be equal to the received chrominance signal.
