ENCODING METHOD, DECODING METHOD, ENCODER, DECODER, PROGRAMME AND RECORDING MEDIUM Russian patent published in 2015 - IPC G10L19/18 H03M7/38 H03M5/06 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to encoding and decoding. An encoding method, which includes obtaining codes corresponding to prediction residues obtained according to prediction analysis, applied to time sequence signals included in a predefined time interval of time sequence input signals with a number of bits to be assigned to codes of prediction codes, respectively, switched according to whether the index which indicates the level of periodicity and/or stationarity, corresponding to time sequence signals in the predefined time interval or time sequence signals in the interval before the predefined time interval of time sequence input signals, satisfies a condition which indicates high periodicity and/or high stationarity, or a condition which indicates low periodicity and/or low stationarity.

EFFECT: higher compression efficiency.
