Abstract:
The present invention provides a method of decoding a video signal comprising a current block using an affine mode, including parsing a skip flag or a merge flag from the video signal, identifying whether the sample number or size of the current block satisfies a preset condition if a skip mode or a merge mode is applied based on the skip flag or merge flag, parsing an affine flag if the condition is satisfied, wherein the affine flag indicates whether an affine prediction mode is applied, and the affine prediction mode indicates a mode deriving a motion vector in a pixel or subblock unit using a control point motion vector, and determining an affine merge mode as an optimal prediction mode if the affine prediction mode is applied based on the affine flag.
