摘要: Certain aspects of the invention may comprise a plurality algorithms and architectures capable performing 3:2 pull-down cadence detection reverse received video signal. In one embodiment, method identifying field in stream comprises generating or more temporally sequential variances, correlating variances to temporal variance patterns associated with video, wherein each is unique phases. system for memory, first circuitry computing equation, second third correlation circuitry, counters, fourth selecting phase.
