High-speed video tape copier |
摘要 |
A video tape copier, particularly a high-speed video tape copier for rapidly copying a video signal from a video tape onto another video tape. The high-speed video tape copier plays back a video tape at an N-tuple speed, band-passes the frequencies of video and audio signals having N-tuple frequencies, respectively, removes noise from the signal, and records the noise-free reproduced signal on another video tape at an N-tuple speed. Further, the video signal can be monitored regardless of whether the video signal is being accurately copied by dividing the frequency of the video signal reproduced at the N-tuple speed by N and displaying the frequency-divided signal as a normal speed video signal on a monitor.
