An Efficient Adaptive Binary Arithmetic Coder and Its Application in Video Coding

Abstract

Adaptive Binary Arithmetic coding is an effective mode of coding. In this paper we propose an efficient adaptive binary arithmetic coder, which is multiplication-free and look-up table free. To achieve this, we combine the probability estimation based on the virtual sliding window technique with the approximation of multiplication and the use of simple operations to calculate the next approximation after the encoding of each binary symbol. We show that the proposed algorithm is faster and provides the better compression efficiency compared to the M-coder in the CABAC entropy coding scheme of the H.264/AVC video coding standard.
