Abstract
An analog-to-digital converting system for converting a composite video signal into a digital signal according to a synchronized clock. The analog-to-digital converting system includes an analog-to-digital converter (ADC), a color burst phase estimator and a phase-locked loop (PLL). The ADC converts the composite video signal to the digital signal according to the synchronized clock, wherein the synchronized clock is synchronized to a frequency of a color burst of a chrominance signal of the composite video signal. The color burst phase estimator, coupled to the ADC, estimates the phase of the color burst carried on the composite video signal. The PLL, coupled to the color burst phase estimator, generates the synchronized clock according to the phase of the color burst estimated by the color burst phase estimator.
