The method adjusts the phase of a quantization clock signal for a video signal automatically based on a received analogue video signal. The method includes a step of determining a horizontal start position and a horizontal end position of a pixel-level transition within the analogue video signal, a step of determining a stable-period start position and a stable-period end position at each transition by sequentially changing an adjustable phase of the quantization clock signal, a step of calculating an appropriate phase of the quantization clock signal based on the determined timings of the beginning and end of the stable periods within the analogue signal, and a step of setting the phase of the quantization clock signal to the calculated appropriate phase.
