    摘要: Systems and methods directed to determining motion in a video signal are provided. A plurality of pixels of a plurality of adjacent field lines of alternating parity of the video signal are evaluated to generate a plurality of differential values. A sign of each differential value is determined, and when each differential value has the same sign, at least one differential value can be compared with a threshold value. Responsive to the comparison of at least one differential value with a threshold value, a motion coefficient indicative of a magnitude of motion associated with one of the plurality of pixels can be generated.

    摘要: Systems and methods directed to processing a video signal, either interlaced or progressive, are provided. A plurality of samples of a reconstructed macroblock of the video signal are evaluated to generate data associated with at least one of the plurality of samples. The data and the reconstructed macroblock can be provided from memory to a deinterlacer unit, and the method can control the deinterlacer unit to deinterlace the reconstructed macroblock based at least in part on the data. Artifacts of the video signal can be identified and removed based on the stored sample data associated with the samples.
