Abstract
A system including a binarization module, an encoding module, and a prediction module. The binarization module is configured to binarize a syntax element and to generate symbols. The encoding module is configured to encode the symbols using context-adaptive binary arithmetic coding (CABAC). The prediction module is configured to generate a prediction for a number of renormalizations to be performed to renormalize an interval range when encoding one of the symbols. The encoding module encodes a next symbol following the one of the symbols based on the prediction before renormalization of the interval range is actually completed.
