Abstract

Context-based adapative binary arithmetic coding (CABAC), as used in video standards such as H.264/AVC, with a renormalization of the interval low value plus range that includes partitioning of the bits of the low value to provide output bits plus low value update without bit-level iterations or aggregation of output bits until a full byte can be output.
