Abstract: The present invention relates to a method for performing entropy decoding on a video signal including a current block. The method comprises the steps of: deriving affine coding information and/or affine prediction mode information of a left block and/or an upper block which are adjacent to the current block; determining a context index of a syntax element associated with an affine prediction of the current block on the basis of at least one of the affine coding information and/or the affine prediction mode information of the left block and/or the upper block; and entropy decoding the syntax element associated with the affine prediction of the current block on the basis of the context index.
