System for digitizing and processing video signals incorporating a circuit (14) for separating the line synchronizing signals from an input video signal, a digital store for this input video signal, a write control circuit (18) for writing the input video signal into the store, a circuit (12) for processing the signals stored in the store and a read control circuit (22) for reading from the store and regaining an output video signal. This system includes a self-contained clock circuit formed by an oscillator (20) whose output signal is conveyed to the write control circuit (18), the read control circuit (22) and a delay counter (21), which gives the line synchronizing signal a delay which is equal to an integral number of times the line period, the output signal of the circuit (14) being conveyed to the read control circuit (22) after having passed through the counter (21).
