This Standard specifies a lossless compression algorithm to reduce the number of bytes required to represent data. The algortihm is known as Adaptive Lossless Data Compression algorithm (ALDC). The numerical identifiers according to ISO/IEC 11576 allocated to this algorithm are: ALDC 512-Byte History Buffer: 3 ALDC 1024-Byte History Buffer: 4 ALDC 2048-Byte History Buffer: 5
