Abstract RU 2586024 C2

FIELD: information technology.

SUBSTANCE: invention relates to means and methods of encoding and decoding images. Device is configured to divide an image into one or more slices each including a plurality of blocks and to code each slice on a block-by-block basis, includes a first coding unit configured to code blocks included in a first portion of slice, and a second coding unit configured to code blocks included in a second portion of slice, wherein, when second coding unit codes an initial block in second portion, second coding unit codes initial included in second portion by referring to a first quantisation parameter provided to slice as an initial value and referred to by first coding unit when first coding units codes initial block in first portion.

EFFECT: technical result is possibility of parallel encoding/decoding whole processing.
