This paper proposes a high-throughput and low-complexity decoder (D_LBAC) based on Logarithmic Binary Arithmetic Coding (LBAC). It can easily implement multiple symbols decoding. The proposed scheme does not use multiplication and division operations nor look up tables (LUTs). It has a simple algorithm structure and only requires additions and shift operations. Experimental results show that it has...

This paper proposes a new efficient bypass coding scheme (EBCS) based on Logarithmic Binary Arithmetic Coding (LBAC). The bypass coding model is used to encode a symbol which has equal probability (0.5). The percentage of the bypass coding model is about 25 in CABAC of H.265/HEVC. The proposed EBCS provides a hardware-efficient design that can significantly increase the processing speed, and it has...
In H.264/MPEG-4 AVC, the quantized coefficients are typically scanned in a fixed zig-zag pattern. This fixed scanning order may not always be optimal for entropy coding. To achieve better entropy coding gain in inter-frame coding, we propose a predictive scan ordering scheme and show that additional inter-frame coding redundancy can be removed by our proposed method. The scanning orders are dynamically...
