发明名称 Digital video signal processing apparatus
摘要 <p>A digital video signal processing apparatus, for curtailing and interpolating digital video signals of a component format, comprises either a half-band high pass filter (100) having a coefficient profile equivalent to that obtained by setting a centre coefficient of an odd-order half-band low pass filter to zero, or a notch filter (200) having a coefficient profile equivalent to that obtained by curtailing a centre coefficient and even-numbered coefficients of such a low pass filter, and a delay line (20) for imparting a predetermined delay time to the signal supplied thereto, whereby multiplexed or time-divided signals can be curtailed and interpolated in a relatively simple construction employing merely a single digital filter. <IMAGE></p>
