FIELD: physics.
SUBSTANCE: invention relates to coding of images and video signal. Result is achieved by the fact that the processor generates, based on the rearrangement information, a forward rearrangement function, which maps pixels from the first representation with a code combination to a second representation with a code combination, and a reverse rearrangement function, wherein the reverse rearrangement function maps pixels from the second code combination representation to the first code combination representation. With respect to the area of the encoded image, the processor generates: region of decoded residual values based on the encoded image; predicted area based on pixels in the reference pixel buffer or previously decoded spatially neighbouring elements; generates a region of reconstructed pixels based on the rearranged region of the decoded residual values, the predicted region, the forward rearrangement function and the reverse rearrangement function; area of output pixels based on area of reconstructed pixels; and stores the output pixel area in the reference pixel buffer.
EFFECT: improved coding efficiency.
