Claim 15:
16. The method of claim 15, wherein the position of the last significant coefficient comprises an initial horizontal coordinate and an initial vertical coordinate of the last significant coefficient, wherein the initial horizontal coordinate is a horizontal distance from the position of the last significant coefficient to an upper-left corner of the current block and the initial vertical coordinate is a vertical distance from the position of the last significant coefficient to the upper-left corner of the current block; and
correspondingly, determining the coordinate information of the last significant coefficient according to the position of the last significant coefficient and the last-significant-coefficient position-reverse flag comprises:
when the last-significant-coefficient position-reverse flag has a first value, 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; or
when the last-significant-coefficient position-reverse flag has a second value, determining the coordinate information of the last significant coefficient directly according to the initial horizontal coordinate and the initial vertical coordinate of the last significant coefficient.
