Abstract
A digital time base corrector uses a memory with a reduced storage capacity, to reduce the cost. Absolute value data of an amplitude and polarity data of a burst signal in a color video signal are written into a memory every horizontal scan period. A signal in which a sync signal interval, a pedestal level interval, and a burst signal interval in the color video signal are eliminated is written as image data into the memory. The absolute value data, polarity data, and image data are read out from the memory. Burst signal data is reproduced on the basis of the absolute value data and polarity data. By inserting the burst signal data, sync signal data, and pedestal level data into the image data, a color video signal is reproduced.
