ABSTRACT:
The invention relates to a synchronization signal decoder and associated method for improving digital image display. A composite video stream includes a distortion compliant signal and a synchronization signal. A level shift circuit is adapted to shift a voltage level of the composite video stream such that the distortion compliant signal is readily distinguishable from the synchronization signal. A level shift disable circuit is adapted to disable the level shift circuit responsive to the composite video stream.
