FIELD: video encoding.

SUBSTANCE: invention relates to video encoding means. Bit stream is analysed to obtain a flag related to video. Bit stream is analysed to obtain a flag of the inverse position of the last significant coefficient and information on the coordinate of the last significant coefficient when the flag relating to the video indicates that the video satisfies a given condition. Position of the last significant coefficient is determined by calculating using information on the coordinate of the last significant coefficient when the flag of the inverse position of the last significant coefficient indicates that the position of the last significant coefficient is changed for the inverse for the current block. All coefficients before the position of the last significant coefficient are decoded according to the specified scanning order to determine coefficients of the current block.

EFFECT: high efficiency of video encoding.
