Patent ID: 7489338

Claim:
A system for controlling color synchronization polarity in a video decoder, the system comprising at least one module adapted to: monitor color synchronization polarity at a plurality of instances over a period of time; generate a first sequence of signals indicative of monitored color synchronization polarity over the period of time; generate a second sequence of signals indicative of correct color synchronization polarity over the period of time; compare corresponding signals of the first and second sequence of signals; generate a third sequence of signals indicative of color synchronization polarity correctness at the plurality of instances based, at least in part, on the compared corresponding signals of the first and second sequence of signals; statistically analyze the third sequence of signals; determine, based at least in part on the statistical analysis of the third sequence of signals, whether color synchronization polarity is correct; and control color synchronization polarity based, at least in part, on the polarity correctness determination.
