Digital Lempel Ziv 1

algorithm (DLZ1) A Lempel-Ziv compression algorithm

which maps variable length input strings to variable length

output symbols. During compression, the algorithm builds a

dictionary of strings which is accessed by means of a hashtable. Compression occurs when input data matches a string

in the table and is replaced with the output symbol.

DLZ1 is used on Digital Linear Tape.
