CE5-related: Alternative implementation of CABAC range sub-interval derivation for CE5.1.5, CE5.1.6 and CE5.1.7
Abstract
This contribution proposes an alternative implementation of the CABAC range sub-interval derivation, for the state-based probability estimator as proposed in JVET-K0430 and further investigated in CE5. Similar to JVET-L0426, the proposed method employs a combination of the range-probability product computation and a table lookup. Additionally, a simple shift operation is applied, which halves the lookup table size. Thus, a (1-dimensional) table lookup, a multiplication and a shift are required. If a computation-based implementation is not desired, a 32x8 lookup table can be used instead.
