Abstract
An off-the-air color video recorder employs frequency interleaved chroma and luminance signal information for purposes of bandwidth compression. During playback, the interleaved luminance and chroma signal information are combed apart, the luminance signal information, however, being subjected to at least one additional stage of comb filtering, preferably limited to that part of the playback spectrum containing the interleaved signal information. With such a technique, playback luminance signal information is comprised of two spectrum parts, one being, say, half the signal resolution of the other.
