ABSTRACT:
A system for converting analog video signals to digital video signals receives an analog video signal that generates a reference horizontal synchronization signal. A phase-locked loop receives the reference horizontal synchronization signal and generates a pixel clock signal and a horizontal synchronization signal from the reference horizontal synchronization signal. An analog-to-digital converter converts the analog video signals to digital video signals. Differences between the measured values of the sampling of a test line of adjacent pixels are formed and phase parameters of the different phase positions are generated by summation of these differences. A phase position of the video signal from the phase parameters is determined, and the phase position is determined with the set phase position, and based on the comparison the set phase is changed.
