SIGNAL PROCESSOR, WINDOW PROVIDER, ENCODED MEDIA SIGNAL, METHOD FOR PROCESSING SIGNAL AND METHOD FOR PROVIDING WINDOW Russian patent published in 2017 - IPC G10L19/02 

FIELD: information technology.

SUBSTANCE: invention relates to data transmission and is intended for processing an input signal with window weight coefficients. Signal processor to provide a processed version of an input signal depending on input signal, includes a windower configured to window a portion of input signal, or of a pre-processed version thereof, in dependence on a signal processing window described by signal processing window values for a plurality of window value index values, in order to obtain processed version of input signal. Signal processor also comprises a window provider for providing signal processing window values for a plurality of window value index values in dependence on one or more window shape parameters.

EFFECT: high efficiency of encoding by adaptation of window characteristics to characteristics of input spectrum of signal.
