ABSTRACT:
A color video signal recording and reproducing method for recording and reproducing a color line sequential TCI signal which prevents, upon different speed reproduction, a possible displacement in hue of a reproduction color video signal. First and second time base compressed chroma signals for one horizontal period are combined with a time base elongated brightness signal for one horizontal period, and type code signals representative of types of the chroma components are added to form encoded color video signals for two tracks. The encoded color video signals are shuffled and recorded simultaneously onto a magnetic tape by two heads. Reproduction color video signals for two tracks obtained by simultaneous reproduction from the magnetic tape are written into and read out from memories each having a plurality of memory areas in accordance with type code signals separated from the reproduction color video signals for two tracks to obtain deshuffled reproduction color video signals for two tracks, which are subsequently decoded to obtain the original color video signal consisting of the brightness signal and first and second chroma signals.
