中文翻译手机版

A high - performance hardware architecture of cabac decoder
解码器硬件结构设计
Context - based adaptive binary arithmetic coding ( cabac ) has been a normative scheme of entropy coding in video coding standards such as h . 264 , avs , for its excellent coding efficiency
基于上下文的自适应二进制算术编码( cabac )以其高效的编码优势,被h . 264 、 avs等视频标准纷纷采用,成为主要的熵编码方案。
By careful analysis , we found that the binarization of the syntax element is a neglected process in cabac , and the binarization ’ s property will directly affect the coding efficiency
通过分析研究得到,对语法元素进行二值化是cabac算法中不可缺少的一个关键步骤,二进制化算法的合理与否直接影响着cabac算法的编码效率的优劣。
The unary code is applied in the binarization of the translation coefficients in the national standard avs . it is preponderant for the small values , but will bring more redundancy for the bigger ones . so the exp - golomb code is introduced for the redundancy reduction
在avs标准中,变换系数level值的二值化方案采用了unary码, unary码对较小的整数值二值化效果较好,但对较大的值则会造成很大的冗余,从而影响了cabac的编码效率。
