1. A video decoding system comprising: an entropy decoding block, the entropy decoding block implemented in a frame level pipelined manner within the entropy decoding block, a numerical calculating block, a deblocking loop filter block implemented with a non bit exact approximate loop filter design, and motion compensation calculating block, wherein the numerical calculating block, the deblocking loop filter block and the motion compensating calculating block are implemented in a row level pipelined manner within each of the numerical calculating block, the deblocking loop filter block and the motion compensating calculating block.
