Abstract
A device for coding/decoding image information is provided to perform a boundary block merge of macro blocks of image information. Further, the DCT coefficients of a block are copied, if that is converted to an exterior block from a boundary block out of left-sided and upper-sided blocks for the purpose of performing a prediction of the DCT coefficients of the block's sub blocks. Thus, the efficiency of a coding/decoding process is enhanced.
