摘要
本文介绍了能用数学解析式表示的变长码和它的三种编译码算法,提出了这种变长码的分解方法,分解后的多个变长码保持了原变长码的编码效率,但降低了编译码的复杂度。
This paper presents a variable length code (VLC) which can be expressed with analytic formula,and three methods of encoding/decoding for the VLC.Then it raises a decomposition method of the VLC.The decomposed multi-VLCs keep coding efficiency of the no-decomposition VLC original,but the complexity of encoding/decoding of the decomposed multi-VLCs is reduced.
