CODING COEFFICIENTS FOR SKIP CONVERSION MODE Russian patent published in 2024 - IPC H04N19/13 H04N19/157 H04N19/18 H04N19/91 

Abstract RU 2813008 C2

FIELD: video encoding and decoding.

SUBSTANCE: increased efficiency is achieved by determining, for the residual block of video data encoded using the skip transform mode, a value for the first adjacent coefficient relative to the coefficient currently being decoded; determining a value for the second adjacent coefficient relative to the coefficient currently being decoded; determining a context offset for the coefficient currently being decoded based on the value for the first adjacent coefficient and the value for the second adjacent coefficient; and decoding a value for the coefficient currently being decoded based on the determined context offset.

EFFECT: increase of efficiency of video encoding/decoding.
