CE5-related: Alternative implementation of CABAC range sub-interval derivation for test CE 5.1.4
Authors: Paul Haase HHI Heiner Kirchhoffer HHI S. Matlage HHI Heiko Schwarz HHI Detlev Marpe HHI Thomas Wiegand HHI
Abstract
This contribution describes an alternative implementation for CABAC range sub-interval derivation, for the state-based probability estimator proposed in JVET-K0430 and was part of CE5 (CE 5.1.4) (JVET-K1025). The proposed method uses a combination of the range-probability product computation and table lookup approaches presented in CE5 (Subtest 2) (JVET-K1025), which means a (1-dimensional) table lookup and a multiplication operation.
Meeting Notes
JVET-L0426 CE5-related: Alternative implementation of CABAC range sub-interval derivation for test CE 5.1.4 [P. Haase, H. Kirchhoffer, S. Matlage, H. Schwarz, D. Marpe, T. Wiegand (HHI)]

This contribution describes an alternative implementation for CABAC range sub-interval derivation, for the state-based probability estimator proposed in JVET-K0430 and was part of CE5 (CE 5.1.4) (JVET-K1025). The proposed method uses a combination of the range-probability product computation and table lookup approaches presented in CE5 (Subtest 2) (JVET-K1025), which means a (1-dimensional) table lookup and a multiplication operation.

This is a different implementation method which generates the same results as the range sub-interval part in the CE contribution JVET-L0462 – is included in complexity analysis of BoG.
