PATENT 390100-2672 ABSTRACT OF THE DISCLOSURE In an apparatus for processing an input video signal that includes a chrominance signal and a luminance signal, the luminance signal is frequency-modulated and the chrominance signal is subsampled, preferably by field-offset subsampling, whereupon, the subsampled chrominance signal is frequency- converted to a lower frequency band than the frequency band of the frequency-modulated luminance signal. The frequency- modulated luminance signal and the frequency-converted subsampled chrominance signal are then combined and the resulting combined signal is recorded on a recording medium such as a magnetic tape. During reproduction of the recorded signal, interpolation among frames is used to reconstruct the chrominance signal. Recording of the frequency-converted subsampled chrominance signal allows for space-efficient recording of the video signal while providing a reproduced chrominance signal that has a relatively wide bandwidth, thereby permitting improved color reproducibility.
