Abstract: The present invention relates to image encoding and decoding of a structure including at least one layer, quality, space, and view and, more particularly, to a method for predicting an upper layer signal using one or more reference layers when encoding and decoding the upper layer. The method can generate a reference picture list including a decoding image of a reference layer comprising lower layers, when generating a reference image list used in predicting motions of the encoding and decoding image of the upper layer and in compensating for the motions. Therefore, the method can improve encoding efficiency by adjusting the position of the decoding image of the reference layers and the order of decoding images of the reference layers in the reference picture list, when generating the reference picture list including the decoding image of the reference layers.
