Patent abstract
A drift reduction method and apparatus. Drift reduction is effected in an MPEG video transcoder by decoding dropped out pixels to form a drift reference frame. The quantization indices in the current macro-block are changed accordingly in a drift reduction process. The compensated quantized frame is then variable length coded to an MPEG bitstream.
