Abstract

In an apparatus for recording and/or reproducing a component video signal having a luminance signal of a wide frequency band so as to be reproducible for obtaining a picture of high resolution and a chroma signal in a chroma band included in the frequency band of the luminance signal substantially below the high end of the latter, a recording signal processing circuit separates from the luminance signal a slant direction luminance signal in a frequency band that includes, and extends substantially above the chroma band, whereupon the luminance signal is suppressed by the slant direction luminance signal and a component of the slant direction luminance signal in the chroma band is frequency-converted to a higher band and is frequency interleaved with the suppressed luminance singal. The chroma signal is frequency interleaved with the suppressed luminance signal and is then added to the latter and to the frequency-converted slant direction luminance signal for forming the video signal which is recorded. In the reproducing mode, a circuit for processing the reproduced video signal separates therefrom the chroma signal, the frequency-converted slant direction luminance signal and the suppressed luminance signal, whereupon the separated frequency converted slant direction luminance signal is frequency-reconverted back to the chroma band and into frequency interleaved relation with the suppressed luminance signal, and the reconverted slant direction luminance signal and the separated suppressed luminance signal are added to provide a luminance signal which, with the separated chroma signal, forms a reproduced component video signal.
