Abstract: A method of decoding a video signal according to the present invention may include: determining whether or not change in brightness is present between a current video including a current block and a reference video of the current video; when it is determined that change in brightness is present between the current video and the reference video, determining weight prediction parameter candidates of the current block; determining a weight prediction parameter of the current block on the basis of index information specifying any of the weight prediction parameter candidates; and performing prediction for the current block on the basis of the weight prediction parameter.

Abstract: According to the present invention, a method of decoding a video signal may include decoding division information that indicates whether a current decoding block is divided into two partial blocks, decoding information that indicates a division direction for the current decoding block when the division information indicates that the current decoding block is divided into the two partial blocks, and dividing the current decoding block into the two partial blocks according to the division direction.
