PURPOSE:To facilitate the checking of the contents of a video signal, by setting the head rotational frequency and the tape travelling speed of both the reproducer and recorder at an N-fold value compared with the normal value and at the same time supplying the video signal to a monitor picture receiver via a wide band demodulator. CONSTITUTION:The VTR1 and 2 have two rotary heads provided with a 180 deg. angle space, and these rotary heads scans a magnetic tape alternately and obliquely. The revolving speed of the two rotary heads and the travelling speed of the magnetic speed are set at an N-fold value compared with the value of the normal recording and reproduction. Thus a high-speed dubbing is carried out. At the same time, the video signal supplied from the VTR1 is supplied to a monitor picture receiver 4 via a wide band demodulator 3. |
