Abstract
The present invention is directed to a reproducing apparatus for reproducing a composite signal from a record bearing medium on which said composite signal is recorded, said composite signal being formed by frequency multiplexing a frequency-modulated luminance signal and a low-band converted carrier chrominance signal which is obtained by frequency-converting a carrier chrominance signal from a high frequency band to a low frequency band. The recording apparatus is constructed to separate the frequency-modulated luminance signal and the low-band converted carrier chrominance signal from the composite signal reproduced from said record bearing medium, to demodulate the frequency-modulated luminance signal to restore the luminance signal, to convert the low-band converted carrier chrominance signal into two kinds of color difference signals and to form R, G and B signals from the luminance signal and the two kinds of color-difference signals thus obtained. According to this construction, it is possible to form and output the R, G and B signals, without causing deterioration of signals.
