FIELD: computer engineering.
SUBSTANCE: invention relates to computer engineering. Disclosed is a method for decoding transform coefficients in a video decoding process in which is obtained from an encoded bit stream a unidimensional matrix of transform coefficients associated with a block of transform coefficients; determining a plurality of subunits of transform coefficients for block of transform coefficients, each subblock from plurality of subblocks having an equal size; determining unified diagonal scanning for scanning information significance of transform coefficients of corresponding subblocks, information of coefficient levels for transform coefficients of corresponding subblocks and plurality of subblocks; scanning unidimensional matrix of transform coefficients according to unified diagonal scanning; and decoding block of transform coefficients.
EFFECT: technical result consists in improvement of efficiency of coding.
