ABSTRACT:
Disclosed is a digital time-base corrector (TBC) capable of correcting not only time-base fluctuation (jitter) but also a time-base change contained in a VTR-reproduced television video signal which experiences large changes in the horizontal scanning period during, for example, special-motion reproduction. The leading edge of a horizontal sync pulse is delayed by a variable delay means, and gate pulse is produced from the delayed leading edge and non-delayed trailing edge of the sync pulse. The delay time is controlled in response to the pulse width of the gate pulse. A burst gate pulse is produced from the trailing edge of the gate pulse. The burst gate pulse gates the video signal to extract a color burst, which is used to produce a clock pulse. The video signal is converted into a digital signal and stored in a digital memory in response to the clock pulse.
