Abstract

PURPOSE:To more securely check a digital video signal by giving a prescribed direct current offset to a color difference signal reproduced by a digital video tape recorder VTR and monitoring the color difference signal. CONSTITUTION:Color difference signals R-Y and B-Y and a luminance signal Y generated at a decoder 10 are supplied through a signal processing circuit to color difference offsetting circuits 12A and 12B and a delaying circuit 13 respectively. Here, at the time of monitoring the color difference signals, a switch S is turned on, the offsetting circuits 12A and 12B are operated, and a DC offset is digitally added to the color difference signals R-Y and B-Y. Next, by monitoring the luminance signal Y and the color difference signals R-Y and B-Y outputted from a matrix circuit 17, the trouble points of circuits in the digital video tape recorder can be easily estimated.
