ABSTRACT:
A system and method for determining signal consistency (e.g., in a video signal processing system) are disclosed. Various aspects of the present invention may, for example, include receiving a first and second signal, each of which includes respective first and second sub-signals. A receiving module may, for example, effect such receiving. The first and second signals may be synchronized according to, at least in part, aspects of their respective first sub-signals. A signal synchronization module may, for example, effect such synchronization. Relative timing between the respective second sub-signals of the first and second synchronized signals may be determined. A timing differential module may, for example, effect such a determination. Various aspects of the present invention may generate a signal indicative of signal consistency based, at least in part, on the determination of relative timing between the respective second sub-signals. An output module may, for example, effect such a signal generation.
