Abstract
In a digital video signal processing device, a digital filter two-dimensionally limits the bandwidth of a digital video signal which is obtained by time-base multiplexing a digital luminance signal with a digital chrominance signal for each horizontal scanning line, and the signal which has been band-limited by the digital filter is offset-subsampled.
