Abstract
Aspects of the invention are directed towards an apparatus and method for detecting conventional and exotic cadences in video sequences. The cadence detector includes a motion auto-correlation unit using the inter-frame/field motion information to detect the cadence and a motion cross-correlation unit using the inter-frame/field motion information and the detected cadence to determine the cadence phase. The cadence detector also may include a reset signal generator to generate a reset signal to control the motion auto-correlation unit and the motion cross-correlation unit. The exotic cadence detector is robust and may support many cadences with reduced cadence detection latency as compared to the prior art.
