Duplicating system for video and audio signals using timebase compression and high speed recorders

An apparatus for duplicating a video signal having video frame intervals, comprising:

• a plurality n of video tape reproducing devices, each video tape reproducing device having a record medium on which said video signal is recorded and transport means for transporting said record medium at a speed n times as high as a normal transport speed and rotary head means having a normal rotary head rotational speed for reproducing said video signal from said record medium to produce a reproduced video signal, the reproduced video signals produced by said plurality n of video tape reproducing devices offset from each other by one of said frame intervals;
• signal processing means for timebase-compressing said reproduced video signals, delaying at least one of the timebase-compressed video signals, and outputting an n-times normal speed reproduced signal;
• and
• at least one video tape recorder having rotary head means for recording the n-times normal speed reproduced signal from said signal processing means on a respective additional record medium at a speed n times as high as a normal recording speed.
