Abstract

PURPOSE:To strengthen a jitter, to eliminate the generation of a spurious interference and to completely reproduce and restore the quantity of information having a composite color video signal by converting the composite color video signal to a pseudo component signal, transmitting and restoring a pseudo component signal to an original color video signal. CONSTITUTION:The NTSC color video signal from a color video signal input terminal 1 is sampled in an A/D converter 2, to supply the sampled data to a field memory 5. At the time, the sampling signal fs of a PLL constitution or a clock generator 4 is used, a writing address synchronizing with the fs is applied to a horizontal scanning memory address counter 6 and a reading address synchronizing therewith is applied to a vertical scanning memory address counter 7. In the two counters of the memory 5, a writing and a reading are alternately executed. The data from this memory 5 is defined to be a crest or a trough for every one line, a luminance signal substantially having no component of a chrominance sub-carrier and D/A converted 8.
