Method for calculating bit length of code word and variable length code table applied to the method therefor

摘要

Improved method for calculating a bit length of a code word and a variable length code table applicable to the same are suggested, in which all possible code words are taken into account, all the possible code words are classified into a plurality of classes of statistically similar code words of the same lengths, these classes together with bit lengths thereof are stored in a table, and a bit length corresponding to a class of a code word provided to the table is produced from the table, whereby a bit length corresponding to a code word provided to the table can be searched faster because the bit lengths are stored in the table as classified.
