摘要：
The method for scanning a transform coefficient of the present invention comprises the steps of: determining a reference transform block for a block to be decoded; deriving a scanning map of the block to be decoded using scanning information of the reference transform block; and executing a reverse-scan on the transform coefficient of the block to be decoded using the derived scanning map. The present invention enhances image encoding/decoding efficiency.
