ABSTRACT:
In a color video signal reproducing apparatus having a plurality of magnetic heads, chrominance signals contained in color video signals respectively reproduced by the plurality of magnetic heads are separately subjected to level or gain control with a view to being equal in level, the levels of the respective chrominance signals are discriminated or detected and, when the level of any one or more of the chrominance signals is outside the control range of the above level or gain control, a so-called color killer operation is carried out.
