Abstract
A method of generating a symmetrical reversible variable length code. This symmetrical reversible variable length code is derived from an original variable length code. Compared with the conventional generating method, the novel method is independent of the bit alignment patterns of the codeword of the original variable length code. In addition, the assignment of codewords of the symmetrical reversible variable length code is performed by a selection priority. Therefore, the overall coding efficiency is improved.
