ENCODING PRINCIPLE THAT MAKES PARALLEL PROCESSING POSSIBLE, TRANSPORT DEMULTIPLEXER AND VIDEO BITSTREAM Russian patent published in 2022 - IPC H04N19/00 H04N19/436 

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.
