Method for reducing the storage and number of computations required for inverse quantization and inverse scan in MPEG video decoding

摘要

The run / level without extend the code by the matrix method of performing an inverse quantization and an inverse scan for the run / level codes and element. The run is converted to a specific coordinate of the matrix. The coordinates can be used to find the inverse quantization value of the inverse quantization matrix. An inverse quantization value, and calculates the quantization level haejyeoseo level is multiplied. A run is being replaced by coordinates, level is replaced with a quantization level.
