Abstract

PURPOSE: To ensure the reproduction of a high-quality picture frame with no nois band even though the magnetic tape is run with different running speed from the recording time by reproducing the area corresponding to the noise band in replace- ment with the 1-field preceding video signal.
CONSTITUTION: The signals reproduced via video heads 1 and 2 are converted into the video signals through VTR reproduction signal process part 7. And the slow- motion reproduction signals are delivered 9 via signal replacement circuit 8. Here if the reproduction signals of heads 1 and 2 are detected 10 at the noise band, pulse signal P showing the noise band is delivered to predicting circuit 11. Circuit 11 receives the tape running speed from capstan motor 5 and gives the 1-field delay to the area corresponding to signal P to give replacement 8 to the area with the 1- field preceding video signal and thus to obtain the reproduction video signal. As a result, a high-quality picture frame free from the noise band can be obtained even through the reproduction is carried out by running the magnetic tape with different speed from the recording.
