Claim Text:
1. A video decoding method comprising: determining whether a current block is a first block with a size that is not a minimum size (4×4) or a second block with a size that is a minimum size (4×4); when the current block is the second block, obtaining, from a bitstream, information indicating whether the current block is inverse-transformed or not, wherein the information is not signaled for the first block and is signaled for the second block; generating a residual image relating to the current block by performing a dequantization on residual coefficients relating to the current block and performing selectively an inverse-transform on the dequantized residual coefficients based on the information indicating whether the current block is inverse-transformed or not; and constructing a decoded image using the residual image relating to the current block.
