ABSTRACT:
A phase based system and method for determining signal consistency (e.g., in a video signal processing system). Various aspects of the present invention may, for example, comprise receiving a first and second signal, each of which comprises a respective first sub-signal. 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. Phase difference between respective sub-signals of the first and second synchronized signals may be determined (e.g., using sample-wise multiplication). Multiplication and accumulator modules may, for example, effect such a determination. A signal may be generated that is indicative of signal consistency based, at least in part, on the determination of phase difference between the respective sub-signals. An output module may, for example, effect such a signal generation.
