FIELD: calculating; counting.
SUBSTANCE: invention relates to computer equipment. Decoder is configured to receive payloads of a sequence of raw bytes describing the image by WPP subflows with one WPP subflow on the LCU image line and encoded with CABAC, from the encoder in tranches into which WPP subflows are segmented, whereby trench boundaries are introduced; entropy decoding of trenches with continuing adaptation of CABAC probabilities across trench boundaries introduced into WPP subflows, and decoding the raw byte sequence payload to obtain an image; decoder is a video decoder.
EFFECT: technical result is to reduce encoding delay in parallel processing environments with less drastic encoding efficiency decreases.
