A method for decoding a video signal, comprising: (S510; S610) obtaining a split flag from the video signal, wherein the split flag indicates whether a coding unit is partitioned; (S520; S620) obtaining split type information of the coding unit when the coding unit is partitioned according to the split flag; and (S530; S660) decoding the coding unit based on the split type information of the coding unit, characterized in, that the split type information includes embedded block type information, wherein the embedded block type information indicates that the coding unit includes an embedded block, wherein the coding unit including the embedded block is a unit for coding based on which inter-prediction is carried out, wherein the embedded block is a block which is not positioned at a square-partitioned location and a dyadic -partitioned location within the coding unit, wherein the embedded block is further partitioned into four blocks through a quadtree decomposition, and wherein a range of possible spatial coordinates of the embedded block is restricted within the coding unit; and the decoding further comprises obtaining number information of embedded blocks for the coding unit; obtaining parameter information of each embedded block based on the number information and obtaining a residual signal of the embedded block; and decoding the embedded block based on the parameter information; generating a remaining block related to the embedded block, wherein the remaining block represents the coding unit except for the embedded block; and decoding the coding unit and obtaining a residual signal of the remaining block.
