摘要： A method and apparatus for entropy coding and decoding a transformation block are provided. The method of entropy coding a transformation block includes: determining, according to a certain scan order, 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; and coding information about the determined location of the last significant transformation coefficient by using a horizontal axis direction location of the last significant transformation coefficient and a vertical axis direction location in the transformation block of the last significant transformation coefficient.
