Abstract
In a time base corrector which converts incoming video signals to digital form and writes the digitized signals in sequentially enabled units of a main 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 from the successive main memory units at a clocking rate which is standard at least at the beginning and end of each line interval and the read out signals are reconverted to analog form for eliminating the time base errors: the clocking rate for reading out the video signals from each of the main memory units is modulated during each line interval in accordance with velocity error information stored in a velocity error memory during writing of such video signals in the respective main memory unit.
