FIELD: physics, computer engineering.
SUBSTANCE: invention relates to computer engineering. A method of coding coefficients associated with a block of video data during a video coding process, the method comprising determining statistics that indicate a probability of each of the X and Y coordinates comprising a given value, when a scanning order associated with the block comprises a first scanning order, wherein X and Y coordinates indicate a horizontal position and a vertical position, respectively, of the last non-zero coefficient within the block according to the scanning order, wherein the scanning order comprises one of a first scanning order and a second scanning order, which is different from the first scanning order; and coding the X and Y coordinates based on the statistics when the scanning order comprises a first scanning order, and interchanging the X and Y coordinates and coding the interchanged X and Y coordinates based on the statistics when the scanning order comprises a second scanning order.
EFFECT: high efficiency of coding the position of a last significant coefficient.
