ABSTRACT:
A video signal recording/reproducing apparatus for recording and reproducing a composite color television signal which is produced in such a manner that a modulated chrominance signal (namely, C-signal) is formed by modulating a color subcarrier with a color difference signal, and then superposed on a high frequency portion of a luminance signal (namely, Y-signal). In order to reconstruct a color picture from the composite color telvision signal without producing cross talk such as cross color and cross luminance, the input of the apparatus is provided with a YC seperation circuit for separating the composite color television signal into Y- and C-signals by utilizing a frame memory, the Y- and C-signals thus obtained are modulated independently of each other at the recording part of the apparatus, to be recorded in a recording medium, and the reproducing part of the apparatus is provided with an output circuit for delivering Y- and C-signals which are reproduced from the recording medium, in a state that the reproduced Y- and C-signals are substantially separated from each other.
