An adaptive digital video signal processing apparatus and method for Y/C separation. In the video signal processing apparatus, an adaptive 2D BPF carries out Y/C separation through comb filtering and bandpass filtering selected according to local characteristics of an image (e.g., based on the direction in which an edge in the image extends in vertical and horizontal directions. The adaptive 2D BPF performs 2D bandpass filtering in general case. The 2D BPF adaptively executes a series of selections of the various filtering operations in a continuous manner.
