Abstract
A method of coding/decoding image information is derived to perform a boundary block merge of the macro blocks of the image information and copy the DCT coefficients of a block that is converted to an exterior block from a boundary one out of left-sided and upper-sided blocks for the use purpose in performing a prediction of the DCT coefficients of the block's sub blocks, thus enhancing the efficiency of a coding/decoding process.
