Claim 16:
17. The method of claim 16, wherein determining the coordinate information of the last significant coefficient by calculation according to the initial horizontal coordinate and the initial vertical coordinate of the last significant coefficient comprises:
determining a width and a height of the current block;
obtaining a horizontal coordinate of the last significant coefficient by subtracting the initial horizontal coordinate of the last significant coefficient from the width of the current block;
obtaining a vertical coordinate of the last significant coefficient by subtracting the initial vertical coordinate of the last significant coefficient from the height of the current block; and
determining the coordinate information of the last significant coefficient according to the horizontal coordinate of the last significant coefficient and the vertical coordinate of the last significant coefficient.
