means for adding said auxiliary modulation result to said
chrominance signal.
8. A video signal processing system for recording a wideband
video signal on a limited bandwith medium, comprising:
an input terminal for receiving a composite video signal;
signal processing means for separating said composite video
signal into a first frequency band including a chrominance signal
and a first luminance signal component, a second frequency band
including a second luminance signal component, and a third
frequency band including a third luminance signal component, said
first and second and third frequency bands being contiguous
frequency bands overlapping only at the edges of said first and
second frequency bands and at the edges of said second and third
frequency bands, said first frequency band containing higher
frequencies than said second frequency band, and said third
frequency band containing lower frequencies than said second
frequency band;
means for generating an augmented chrominance signal by
folding said second luminance signal component into said first
frequency band so as to interleave with said first luminance
signal component; and
means for recording said third luminance signal component
and said augmented chrominance signal.
