Patent ID: 7630441

Claim:
An apparatus for pipelining decoding a coded bitstream, the apparatus comprising: a storage unit which stores some of the pixel values of each of recovered images corresponding to previous macroblocks as neighboring pixel values; a motion predictor which: predicts motion in a picture corresponding to a current macroblock using the neighboring pixel values read from the storage unit, recovers an original image from the current macroblock using a result of the prediction of the motion in the picture and residue information, and stores some of the pixel values of the recovered image corresponding to the current macroblock in the storage unit; and a deblocking filter which deblocking-filters the recovered image, wherein the recovery of the original image with respect to an nth macroblock in the motion predictor and the deblocking-filtering of the recovered image corresponding to an (n−1)th macroblock in the deblocking filter are simultaneously performed.
