Definition

Process that maps a stochastic information source to a sequence of code symbols to reduce the average number of bits required to represent the source by identifying and removing statistical or structural redundancy at the source; includes both lossless and lossy mappings and is specified with respect to a source model, an allowable distortion criterion (if any), and implementation constraints.
