ABSTRACT:
In a time base corrector which converts incoming video signals to digital form and writes the digitized signals in a memory at a clocking rate varying generally in accordance with time base errors in the incoming signals, whereupon the signals temporarily stored in the memory are read out or fetched therefrom at a standard clocking rate and reconverted to analog form for eliminating the time base errors; the memory is composed of a plurality of cyclically enabled memory units which each have a capacity to store an even number of line intervals of the video signals.
