Zusammenfassung:	According to the present invention, there is provided a video signal processing method of dividing an input image on a per-block basis for encoding, the method including: determining, at a division determination step, whether to divide a current block; dividing, at a block division step, the current block into multiple sub blocks on the basis of the determination; generating block division information on division of the current block; and encoding, at an encoding step, the block division information, the current block, or the sub blocks. Examples of division of the block according to the present invention include division using N-ary tree structures, such as the quad tree structure, the binary tree structure, and/or the triple tree structure.
