Abstract

PURPOSE:To prevent degradation of the resolution in the vertical direction of the reproducing picture, by transmissting the overall signal wherein the chrominance signal has the frequency converted to the low band side of the sinking band and higher harmonic components of the luminance signal have the frequency converted to the high band side of the sinking band. CONSTITUTION:The output of comb line filter 3 is subtracted from the color video signal from terminal 1 by synthesizer 6, and signal SS1 having sinking band 12 where higher harmonic components in the vertical direction of the middle band and the high band of the luminance signal of the frequency band of f1 or more and chrominance signal SC1 are eliminated appears in the output of synthesizer 6. Meanwhile, chrominance signal SC1 which does not include the luminance signal is subjected to frequency conversion in 8C and 8Y, and results are synthesized in 9 and are superposed onto the low band side in sinking band 12. Simultaneously, higher harmonic components of the luminance signal which appears from BPF 7Y are subjected to frequency conversion in 8Y and are converted to the high band side in band 12, and the overall signal is output from terminal 11. In the receiving side, the original signal is reproduced according to reverse procedures. Consequently, degradation of the resolution in the vertical direction of te reproducing picture is prevented.
