Patent ID: 7587091

Claim:
An apparatus comprising: an adaptive de-interlacer to form a plurality of de-interlaced frames from a plurality of interlaced fields decoded from an interlaced video stream, the adaptive de-interlacer including: a motion compensator having a plurality of registers to move a location of a plurality of reference blocks of pixels of the interlaced fields using a plurality of motion vectors decoded from the interlaced video stream; a low pass digital filter to de-interlace a plurality of moved reference blocks of pixels and a plurality of current blocks of pixels decoded from the interlaced video stream, wherein the low pass digital filter includes a plurality of low pass digital filter coefficients adjustable according to a plurality of discrete cosine transform (DCT) high frequency coefficients decoded from the interlaced video stream, wherein the adaptive de-interlacer includes a motion vector extractor to extract the motion vectors, and a decoder to decode the DCT high frequency coefficients for the fields, and a map constructor to construct map of the motion vectors for the fields, wherein the low pass digital filter includes a temporal vertical filter to filter a plurality of pixels from the reference block and the current block, wherein the plurality of pixels are vertically aligned in location.
