<p>A digital video signal reproducing apparatus is arranged such that when a low frequency component of a reproduced signal is extracted, the reproduced signal forms a reproduced image plane. When a low frequency component of a reproduced signal is extracted but a high frequency component thereof is not extracted, the low frequency component thus extracted is compared with a low frequency component of a previously or subsequently reproduced signal. If the two low frequency components are substantially equal to each other, the reproduced signal is concealed to form a reproduced image plane, and if not substantially equal to each other, the reproduced signal forms a reproduced image plane without being concealed.</p> |
