发明名称 FM video demodulator with flutter correction
摘要 Video reproduction apparatus in which image degradation which may result from flutter components of an FM video signal reproduced from magnetic tape are eliminated by means of a flutter correction signal applied to a period FM demodulator. The corrected demodulated analog video signal produces an accurate display of the original image. A scene represented by an FM video signal is recorded in a plurality of longitudinal tracks on magnetic tape along with a timing signal recorded in a timing track parallel to the video tracks. Any flutter in the video signals reproduced from the video tracks is also present in the timing signal reproduced simultaneously from the timing track. A flutter correction signal is derived from the timing signal and applied to a plurality of FM demodulators to cancel the flutter error in the demodulated video signals.
