ENCODER AND METHOD FOR PREDICTIVELY ENCODING, DECODER AND METHOD FOR DECODING, SYSTEM AND METHOD FOR PREDICTIVELY ENCODING AND DECODING AND PREDICTIVELY ENCODED INFORMATION SIGNAL.

摘要

An encoder (100) for predictively encoding a signal (105) having a sequence of signal values (s(n)) comprises a predictor (110) for performing an adaptive prediction in dependence on the signal (105) (s(n)), and in dependence on one or more weighting values (111) (ω1), to obtain predicted signal values (115) (s'(n)), wherein the predictor (110) is configured to reset the weighting values (111) at times which are dependent on the signal (105), and wherein the predictor (110) is configured to adapt the weighting values (111) to the signal (105) between subsequent resets.
