ABSTRACT:
In an apparatus having a rotary magnetic head assembly for reproducing a color video signal including a chrominance signal recorded on a magnetic tape in a plurality of successive oblique tracks which selectively have a first width or a second width narrower than the first width; a circuit is provided for processing the chrominance signal separated from the reproduced color video signal and comprises a comb-filter circuit receiving the separated chrominance signal and being selectively controllable to provide a simple or non-feedback type comb-filter or a feedback-type comb-filter, and a filter controller which causes the comb-filter circuit to provide the simple or non-feedback comb-filter when the color video signal is reproduced from a magnetic tape having oblique tracks of the first width and to provide the feedback-type comb-filter when the color video signal is reproduced from a magnetic tape having oblique tracks of the second width.
