<p>PURPOSE:To improve the operability at the time of dubbing by making a reproducing state of one deck and a recording state of another deck by operating a single PB/REC switch and releasing simultaneously both decks from their high picture quality processing functions workable for the time of the normal recording and reproducing. CONSTITUTION:At the time of dubbing, a mechanical system of a 1st recording and reproducing deck 2a is changed over to a reproducing mode, and at the same time, a mechanical system of a 2nd recording and reproducing deck 2b is changed over to a recording mode by turning on the single PB/REC switch 12. In addition, simultaneously with these changeovers, a noise canceler 10a in a 1st reproducing system video signal processing circuit 6a is released, while a detail enhancer 9b in a 2nd recording system video signal processing circuit 4b is released as well by the PB/REC switch 12. By this method, the operability at the time of dubbing can be improved.</p> |
