Abstract
(EN) 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. 25 cl, 19 dwg
(RU) Изобретение относится к области вычислительной техники. Технический результат заключается в уменьшении задержки кодирования в средах параллельной обработки с менее резкими снижениями эффективности кодирования. Декодер выполненен с возможностью приема полезных данных последовательности необработанных байтов, описывающих изображение подпотоками WPP с одним подпотоком WPP на LCU-строку изображения и кодированных с использованием CABAC, от кодера в траншах, на которые сегментируются подпотоки WPP, посредством чего в них вводятся границы траншей; энтропийного декодирования траншей с продолжением адаптации вероятностей CABAC через границы траншей, введенные в подпотоки WPP, и декодирования полезных данных последовательности необработанных байтов для получения изображения; при этом декодер является видеодекодером. 10 н. и 15 з.п. ф-лы, 19 ил.
