Time-base compensator

Abstract From the Canadian patent

Timing errors in a color television signal equal to a fraction of the nominal period of one cycle of color burst are corrected by clocking an analog-to-digital converter during each horizontal line interval of the television signal with two clock signals having the same nominal frequency equal to a multiple of that of the color burst. During the color burst interval of each horizontal line the analog-to-digital, converter is clocked by a stable time base reference clock signal and the obtained digitized color burst is stored in a recyclable digital memory. Following the color burst interval the stored digitized color burst is regenerated for the remainder of the horizontal line and a clock …
