| Summary: | A method and apparatus for entropy coding and decoding a transformation block. The method of entropy coding a transformation block includes determining a location of a last significant transformation coefficient having a non-zero value from among transformation coefficients included in a transformation block having a certain size, according to a certain scan order; and coding information about the location of the last significant transformation coefficient by using its horizontal axis direction location and its vertical axis direction location in the transformation block. |
