ABSTRACT:
A video signal reproducing apparatus for reproducing a recorded video signal from a magnetic recording medium comprises a reproducing circuit for reproducing a recorded frequency division multiplexed signal of an angle modulated luminance signal and a frequency converted carrier chrominance signal which has been frequency-converted into a low frequency band, a demodulating circuit for obtaining a reproduced luminance signal, a filter circuit for filtering a specific frequency component within the reproduced luminance signal, a level detecting circuit for detecting an output signal level of the filter circuit, a frequency converter circuit for obtaining a reproduced carrier chrominance signal, and a level controlling circuit for controlling the level of the reproduced carrier chrominance signal based on an output detection signal of the level detecting circuit.
