ABSTRACT:
A digital television receiver includes an analog-to-digital converter having a controllable scaling factor and offset. To improve resolution of the digital samples, the scaling factor is increased and the offset is changed when the synchronizing and color reference burst portions of the composite video signal are being converted. In addition, the scaling can be greatly increased at selected times so that the phase of the color reference burst can be more accurately determined.
