LZ methods utilize a table based compression model where table entries are subsitituted for redundant data. The table itself is often Huffman encoded (eg. SHRI, LZX).

LZ methods utilize a table based compression model where table entries are subsitituted for redundant data. For most LZ methods, this table is generated dynamically from earlier data in the input. The table itself is often Huffman encoded (eg. SHRI, LZX).
