METHOD binary coding quantization INDICATORS signal envelope, a method of decoding the signal envelope and the appropriate plug encoding and decoding

摘要

FIELD: information technology.;SUBSTANCE: method for binary encoding a signal envelope comprises a variable length first coding mode which incorporates envelope saturation detection, and a second coding mode, executed in parallel with the first coding mode. One of the coding modes is selected as a function of a code length criterion and the result of detecting envelope saturation in the first coding mode.;EFFECT: high coding efficiency.;15 cl, 14 dwg
