CONSTITUTION:A line sequential color difference signal 2d obtained by compressing a line sequential color difference signal 2b to 1/5 by the time base in the recording circuit is outputted from an LPF50. In such a case, the AC level of the line sequential color difference 2b is clamped at a clamp circuit 5 at the front step of an A/D converter 7 and it goes to be the AC level of the line sequential color difference signal 2d compressed by the time base as it is. At a clamp circuit 52, the AC level of the line sequential color difference signal 2d is clamped, and the frequency is modulated so that the AC level becomes a constant FM carrier at a frequency modulating device 56.
