demodulated luminance signals y to a mixer 47 in addition the reproduced signal output by reproducing amplifier 45 is supplied to bandpass filters 48 and 49 which respectively provide the frequency modulated audio signal afm and the tracking pilot signal atf to output terminals 50 and 51 by passing respective passbands corresponding to those signals the output signal of reproducing amplifier 45 is also supplied to a bandpass filter 52 which has a passband with a center frequency at 743 khz for extracting the down converted chrominance signals c 39 the output of bandpass filter 52 is supplied to chrominance signal reproducing processing circuit 53 for conversion into baseband color difference signals r y 39 and b 39 y 39 the resulting frequency converted color difference signals r y 39 and b y 39 are supplied to a subsample circuit 54 for sampling at a sampling rate of fsc 4 895 khz then the sampled color difference signals are supplied to an interpolating circuit 55 which interpolates the signals to provide color difference signals having a transmission band of fsc 2 interpolating circuit 55 includes a frame memory and interpolates using four fields of color difference signals which may for example be the four most recent fields or alternatively may include both prior and subsequent fields the interpolated color difference signals are supplied to a chrominance noise reducing cnr circuit 56 in which noise elimination is carried out the resulting signal is then provided to an encoder 57 which outputs chrominance signals modulated with the 3 58 mhz color subcarrier these signals are provided to mixer 47.
