Abstract
An arithmetic decoding apparatus is provided that carries out complete pipeline processing. Fluctuations in the pipeline caused by occurrence of the normalization are resolved by using a future-predicted Qe memory. In coding multi-valued images, common contexts are generated without distinguishing between AC and DC components of DCT coefficients.
