Abstract
(EN) FIELD: data processing. SUBSTANCE: invention relates to coding principle, which enables parallel processing. Disclosed is a decoder configured to receive raw byte sequence payload describing a picture with WPP sub-streams with one WPP substream per LCU line of picture and encoded using CABAC, from encoder in tranches into which are segmented WPP sub-streams, by means of which boundaries of tranches are input therein; entropy decoding of tranches with continuation of adaptation of probabilities of CABAC through boundaries of tranches, introduced into WPP sub-streams; and decoding raw byte sequence payload to obtain a picture. EFFECT: technical results is improved efficiency of coding with small delay in parallel processing media. 23 cl, 20 dwg
(RU) Изобретение относится к принципу кодирования, делающему возможным параллельную обработку. Техническим результатам является повышение эффективности кодирования с малой задержкой в средах параллельной обработки. Заявлен декодер, выполненный с возможностью приема полезных данных последовательности необработанных байтов, описывающей изображение подпотоками WPP с одним подпотоком WPP на LCU-строку изображения и кодированной с использованием САВАС, от кодера в траншах, на которые сегментируются подпотоки WPP, посредством чего в них вводятся границы траншей; энтропийного декодирования траншей с продолжением адаптации вероятностей САВАС через границы траншей, введенные в подпотоки WPP; и декодирования полезных данных последовательности необработанных байтов для получения изображения. 8 н. и 15 з.п. ф-лы, 20 ил.
