ENCODER AND PREDICTIVE CODING METHOD, DECODER AND DECODING METHOD, PREDICTIVE CODING AND DECODING SYSTEM AND METHOD, AND PREDICTIVE CODED INFORMATION SIGNAL Russian patent published in 2016 - IPC G10L19/06 H03M7/30

Abstract RU 2573278 C2

FIELD: physics, communication.

SUBSTANCE: invention relates to predictive coding of an information signal. An encoder for predictive coding of an information signal, having a sequence of signal values (s(n)), comprises a prediction unit for performing adaptive prediction depending on the sequence of signal values (s(n)) and depending on one or more weight values ω_i to obtain values of a predicted signal (s'(n)), wherein the prediction unit is configured to reset weight values at moments in time which depend on values of the information signal, and wherein the prediction unit is configured to adapt weight values to the signal between subsequent resets.

EFFECT: high accuracy of predictive coding of an information signal and improved maintenance of signal quality.
