METHOD FOR VARYING REPRODUCTION TIME OF VIDEO SIGNAL

摘要

PROBLEM TO BE SOLVED: To provide a reproduction time variable method for a video signal where a reproduction time if changed consciously, while preventing deterioration in type quality of the video signal. SOLUTION: A synchronization signal generator 26 generates plural synchronization signals, having a different field frequency from a prescribed absolute reference synchronization signal corresponding to a reproduction speed control signal. A modified player 17 receives any of the plural synchronization signals as an external reference signal to change a reproduction speed of a video signal recorded on a cassette 13. A scanning line converter 18 converts a scanning line number of the video signal reproduced from the player 17. A field frequency converter 19 converts the field frequency of the reproduction video signal from the converter 18, so as to have the same frequency as the prescribed absolute reference synchronization signal.
