Abstract

PURPOSE: To compensate the signal absence of a VTR regeneration output only by using one kind of a delay line of 3.58MHz.
CONSTITUTION: Picture signal 1 of a chroma signal converted into a low band of 2.56MHz and a luminance signal both multiplexed is changed into output chroma signal 31 by way of the 1st absent-signal compensating switch 3 and comb line filter CF and this chroma signal is applied as a luminance signal without signal absence to the 3rd absent-signal compensating switch 20. A luminance signal in case of the occurrence of signal absence is generated by processing picture signal 1 by the circuit group including the 2nd absent-signal compensating switch 23 and broad-band delay circuit 24, and then applied to the 3rd switch 20. Output luminance signal 32 is obtained from switch 20. Consequently, an expensive 1H delay line mass-produced is used to make it possible to compensate the absence of a chroma signal and a luminance signal.
