H03M7/405 - 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 variable length codes, e.g. Shannon-Fano code, Huffman code, Morse code; Fixed length to variable length coding; Prefix coding; Adaptive prefix coding Tree adaptation
