Original Abstract Submitted

An image decoding method performed by a decoding apparatus, an image encoding method performed by an image encoding apparatus, and a transmission method for image data are discussed. The image decoding method can include obtaining a coding block by partitioning an image, determining a size of the coding block, determining a split type for the coding block based on the size of the coding block, deriving a current block split from the coding block based on the split type for the coding block, and reconstructing the current block. Based on that the size of the coding block is equal to or greater than a first size, the split type for the coding block is implicitly determined as that the coding block is split into four equal-sized subblocks.
