1. A method of decoding an image signal, comprising:
receiving a bitstream including the image signal;
dividing, based on a quad division, a first coding block in the image signal into four second coding blocks; and
dividing, based on a triple division, a second coding block into three third coding blocks,
wherein a size of one of the three third coding blocks is twice a size of each of the other two of the three third coding blocks,
wherein the other two of the three third coding blocks have the same size,
wherein the one of the three third coding blocks is located between the other two of the three third coding blocks,
wherein at least one of the three third coding blocks is further divided into two fourth coding blocks based on first information and second information,
wherein the first information indicates whether to divide based on a binary division and the second information indicates whether a division direction is a vertical direction or a horizontal direction, and
wherein, with respect to the binary division for the one of the three third coding blocks located between the other two of the three third coding blocks, it is restricted so as not to be divided in a same division direction as the triple division for the second coding block.
