Abstract

PURPOSE:To perform high density recording of sequential chroma signal and separation of an index signal, by multiplexing a sequential chroma signal and index signal with low frequency convertion in time division and recording them with an FM luminance signal. CONSTITUTION:An output signal ST of a color cemera 1 is a synthesis signal consisting of a chroma signal Sc of time division and a pulse width modulation with a luminance signal SYW and an index signal SI for signal separation. The signal ST is applied to a carrier trap circuit 3 and only the signal SYW is picked up and applied to an LPF 4 to form a low frequency luminance signal SY with band limit. After the signal SY is synthesized with a composite synchronizing signal SS at a synthesizer 5, the signal is applied to an FM modulator 7 for FM modulation. On the other hand, the signal ST is picked up for the signal SC including the signal SI at a BPF 11, the picked up signals SI and SC are applied to a separation circuit 12 to separate the both. In low-frequency-converting the signal SC, a carrier CS from the oscillator 20 is phase-shifted at a phase shift circuit 21.
