Abstract
PURPOSE:To obtain a sufficient time base fluctuation eliminating characteristic in a domestic VTR by obtaining a chrominance signal having the same time base fluctuation component as that of a luminance signal by decoding a carrier chrominance signal from which the phase fluctuation of a carrier is eliminated on the chrominance signal of a base band. CONSTITUTION:The phase fluctuation of the carrier due to time base fluctuation is eliminated from a low-pass conversion chrominance signal separated from a reproducing video signal by frequency conversion, and a frequency-converted chrominance signal is decoded to the chrominance signal of the base band, and the chrominance signal of the base band and the luminance signal separated and demodulated from the reproducing video signal are written on a memory independently. And a clock generated by applying control so that momentary phase locking can be applied on a horizontal synchronizing signal separated from the luminance signal at every horizontal period is used as a write clock, and also, a constant clock without generating the time base fluctuation is used as a readout clock. Furthermore, after the chrominance signal read out from the memory is encoded on the carrier chrominance signal, it is synthesized with the luminance signal read out from the same memory, then, the repdocuing video signal can be obtained.
