Entropy coding and decoding methods are provided which improve an overall coding efficiency by selectively applying context-based adaptive coding methods having different characteristics. An entropy coding method includes performing context-based adaptive variable length coding on a data symbol; performing context-based adaptive arithmetic coding on the data symbol; receiving information regarding a reference block where the coding efficiency of the context-based adaptive arithmetic coding is higher than that of the context-based adaptive variable length coding; and forming a slice which includes the reference block, and performing the context-based adaptive arithmetic coding on the blocks coded after the reference block. |
