PURPOSE:To make the scale of hardware small without requiring any high- quality reproducing picture in designating an editing point by editing a digital VTR using 2 sets of reproducing devices and one set of recording device by means of one set of processor. CONSTITUTION:A processor 4 of an editing device of a digital VTR is provided with a recording processing circuit 5R and a reproduction processing circuit 5P processing a digital color signal of 4, 2, 2 system. The reproducing signal from 2 sets of reproducing devices l, 2 is fed to the circuit 5P of the processor 4 via video and audio switches 8, 9 respectively. The circuits 8, 9 halve the sampling frequency of the color video signal and make the total data quantity equal to that of the 4, 2, 2 system. The reproduced output of the circuit 5P of the processor 4 is separated by a reproducing switch circuit 11 and two reproduced pictures are monitored by monitors 14-16 to make the scale of hardware small.
