Abstract:
1. A variable length decoding method utilizing a reordered index decoding look-up-table (LUT), and is applicable in a variable length decoder, comprising the following steps: establishing an output correlation rule based on two or more decoding LUT's, thus integrating said respective decoding LUT's into a reordered index decoding LUT in said variable length decoder; reading a codeword string input to said variable length decoder, and generating at least a corresponding reordered index value through decoding; selecting one of at least one said reordered index value based on the previous decoding result; executing the following steps utilizing said selected reordered index value: searching and finding out a reordered index output result through said reordered index decoding look-up-table (LUT) by making use of said remapping index value; and performing a logic operation using said reordered index output result and said compensation value, hereby obtaining at least an output result.
