Abstract
(EN) FIELD: data encoding and decoding. SUBSTANCE: invention relates to a decoder, encoder, methods, system and data carriers for encoding/decoding payload data of a sequence of raw bytes. The encoder is configured to generate, by encoding the image, payload data of a sequence of raw bytes so that they describe said image by WPP substreams with one WPP substream per LCU line of the image, by entropy encoding the sequence of raw bytes using CABAC, passing the sequence of raw bytes to tranches into which WPP sub-streams are segmented, whereby tranche boundaries are introduced into them, and continuing to adapt the CABAC probabilities while performing entropy encoding across the tranche boundaries introduced in the WPP substreams, wherein the encoder uses the transformation of the prediction residual data to generate a raw byte sequence payload. EFFECT: improving the efficiency of encoding/decoding data. 23 cl, 20 dwg
(RU) Изобретение относится к декодеру, кодеру, способам, системе и носителям данных для кодирования-декодирования полезных данных последовательности необработанных байтов. Технический результат заключается в повышении эффективности кодирования-декодирования данных. Кодер выполнен с возможностью формирования, посредством кодирования изображения, полезных данных последовательности необработанных байтов так, чтобы они описывали упомянутое изображение подпотоками WPP с одним подпотоком WPP на LCU-строку изображения, с помощью энтропийного кодирования последовательности необработанных байтов, используя CABAC, передачи последовательности необработанных байтов в траншах, на которые сегментированы подпотоки WPP, посредством чего в них введены границы траншей, и продолжения адаптации вероятностей CABAC при выполнении энтропийного кодирования через границы траншей, введенные в подпотоки WPP, при этом кодер использует преобразование остаточных данных предсказания для формирования полезных данных последовательности необработанных байтов. 8 н. и 15 з.п. ф-лы, 20 ил.
