Digital Lempel Ziv 1


Digital Lempel Ziv 1

(algorithm)(DLZ1) A Lempel-Ziv compression algorithmwhich maps variable length input strings to variable lengthoutput symbols. During compression, the algorithm builds adictionary of strings which is accessed by means of a hash table. Compression occurs when input data matches a stringin the table and is replaced with the output symbol.

DLZ1 is used on Digital Linear Tape.
