Defines a lossless compression algorithm for reduction of the number of bytes needed to represent data. Known as Adaptive Lossless Data Compression algorithm (ALDC).

This International 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/IEC11576 allocated to this algorithm are:

ALDC 512-Byte History Buffer: 3

ALDC 1024-Byte History Buffer: 4

ALDC 2048-Byte History Buffer: 5
