H03M7/3046 - CPC Classification

Classification description:

Conversion of a code where information is represented by a given sequence or number of digits to a code where the same, similar or subset of information is represented by a different sequence or number of digits; Compression ; Expansion; Suppression of unnecessary data, e.g. redundancy reduction; Conversion to or from differential modulation; Conversion to or from differential modulation with several bits only, i.e. the difference between successive samples being coded by more than one bit, e.g. differential pulse code modulation [DPCM] adaptive, e.g. adaptive differential pulse code modulation [ADPCM]
