Abstract

PURPOSE:To adjust a picture quality at the time of dubbing by providing a picture quality adjusting circuit between a first switching circuit for switching the input terminal side of a video signal and the output side of a reproducing circuit and a second switching circuit for switching an input side to a recording circuit and the output terminal side of the video signal. CONSTITUTION:At the time of connecting the first the third switching circuits 19, 31, 35 to EE terminal 20, 34, 36, sides, the video signal from an AGC circuit (automatic gain control) 17 has the picture quality adjusted in a picture quality adjusting circuit 26 and outputted from a video output terminal 27, modulated in a high frequency modulating circuit 28 and outputted from a television signal output terminal 29. Simultaneously, the video signal having the picture quality adjusted in the picture quality adjusting circuit 26 is recorded on a video tape 21 through the recording circuit 18 and a video head 22. At the time of switching the first the third switching circuits 19, 31, 35 to PB terminal 24, 33, 37 sides, the video signal of the video tape 21 is detected by the video head 22, reproduced in a reproducing circuit 23, further, the picture quality is adjusted in the picture quality adjusting circuit 26 and the video signal is outputted from the video output terminal 27 and the television signal output terminal 29.
