Abstract: A method of decoding an image using a quadtree structure, according to one embodiment of the present invention, comprises the following steps: decoding unified code block flag information in an encoding unit; decoding a split information flag on the basis of the unified code block flag information and information on a size of a transform unit; and decoding code block flag information of the transform unit if it is determined that the transform unit does not split further on the basis of the split information flag, wherein the split information flag needs not be decoded if a transform coefficient of the transform unit does not exist in said step of decoding the split information flag. As a result, efficiency in encoding/decoding can be improved and complexity can be reduced.
