Abstract

PURPOSE:To establish the VTR unit which can obtain stable and beautiful color reproducing screen, by compressing the luminance signal for the time axis for a given period and inserting the carrier chrominance signal in time axis compression to the space period produced by the compression and recording it. CONSTITUTION:The NTSC color video signal from the terminal 11 is separated into the luminance signal Sy and carrier chrominance signal Ss with the low pass and band pass filters 12, 21. The signal Sy is made to the signal Sq in time axis compression so that it is located in the first half of the horizontal period in one horizontal period unit with the memory 13. The signal Ss is in frequency conversion with the AFC circuit 24 and frequency converter 22 so that the up and down side band waves are interleaving, and made to the time axis compression signal Se with the memory 23 so that it is located at the latter half of one horizontal period. The memories 13, 23 are controlled with the clock produced with the synchronous separation circuit 31 and clock pulse forming circuit 32. The signals Sq and Se are fed to the head 17 via the addition circuit 14, FM modulation circuit 15, and recording amplifier 16.
