Standard ECMA-222
Adaptive Lossless Data Compression Algorithm

(June 1995)

This Ecma standard specifies a lossless compression algorithm to reduce the number of bytes required to represent data. The algorithm is known as Adaptive Lossless Data Compression algorithm (ALDC). The numerical identifiers according to ISO/IEC 11576 Link to non-Ecma site. Ecma is not responsible for the contents of the site. allocated to this algorithm are:

ALDC 512-Byte History Buffer: 3

ALDC 1024-Byte History Buffer: 4

ALDC 2048-Byte History Buffer: 5
