Standard ECMA-151
Data Compression for Information Interchange
- Adaptive Coding with Embedded Dictionary - DLCZ Algorithm
(June 1991)
This Ecma Standard specifies a lossless compression algorithm
to reduce the number of bits required to represent information
coded by means of 8-bit bytes. This algorithm is known as DCLZ
(Data Compression according to Lempel and Ziw).
This Ecma Standard specifies neither the strategy for resetting
the dictionary nor that for freezing it, as these are implementation-dependent.
This algorithm is particularly useful when information has to
be recorded on an interchangeable medium. Its use is not limited
to this application.
