Abstract: A method and apparatus for a digital video display. A digital display device receives an analog signal representing an image formed of pixels in video lines and a signal containing a synchronization waveform for the image. An analog-to-digital converter (ADC) receives the analog signal and converts it to a sampled digital waveform. A phase-locked loop including a programmable frequency divider controls the sampling time for the ADC. The programmable frequency divider is controlled by a dividing-ratio algorithm that selects a dividing ratio, measures the number of pixels in a video line using the dividing ratio, and recomputes the dividing ratio by multiplying the selected dividing ratio by the expected number of pixels in a video line and dividing by the measured number of pixels. The sampling phase for the ADC is selected by a sampling-phase control algorithm that minimizes a function representative of the flatness of the sampled digital waveform.
