Locations of reference blocks of pixels of decoded interlaced video reference fields decoded from a compressed stream of video data are computed using motion vectors decoded from the same stream of video data. The reference block computed locations are de-interlaced with current blocks from current video fields decoded from the compressed streams of video data by low pass filtering light intensities of adjacent pixels of the reference and current blocks using low pass filter with coefficients adjustable according to discrete cosine transform (DCT) high frequency coefficients decoded from the coded stream. In addition, moving edges or objects of the de-interlaced blocks of pixels can be identified by comparing the decoded motion vector of the reference blocks to a threshold value. Then proper or more appealing light intensities for the moving edge pixels can be interpolated.
