Abstract: In video tape recording apparatus composite video signals are separated into their luminance and chrominance components for processing prior to recording. The luminance components are digitized, adaptively temporal and spatial filtered, and folded into a reduced frequency spectrum to generate a digital signal that is converted to analog form to modulate the frequency of the luminance carrier signal used in video tape recording. The chrominance components are converted to the color-under signals used in video tape recording. In video tape playback apparatus the color-under signals are converted up in frequency to provide chrominance components for inclusion in reproduced composite video signals.
