  • Time-base-correction in video recording using a frequency-modulated carrier
    Patent number: 5526129
    Abstract: A circuit for recording and reproducing a TBC reference signal for use in video recording/reproducing systems includes a circuit for adding to a video signal to be recorded a TBC reference signal in which the TBC reference signal has a period adaptively varying corresponding to a synchronizing variation of the video signal; and a circuit for extracting and reproducing a TBC reference signal from a video signal read-out from the recording medium in order to correct time-base errors in the video signal. The circuit corrects time-base errors of the video signal according to a TBC reference signal reproduced along with the video signal from the recording medium during reproduction.
