ABSTRACT:
A method and apparatus for compression of data includes first encoding data characters according to a relative frequency of use table for each character to produce a frequency code. This frequency code is then compressed using a modified Huffman code. The code is modified by restricting the maximum word length to a predetermined number of bits. Different types of text can be encoded according to different frequency of use tables to maximize compression efficiency for various types of source data with minimum data processing.
