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 improve encoding efficiency by separating a space quality reference layer list, which comprises space and quality layers referred within the same view as the relevant layer, from a view reference layer list, which comprises space and quality layers the same as the relevant layer; and by predicting between layers by taking into consideration the characteristics of each layer, when encoding and decoding an encoding and decoding image of the upper layer.

Abstract: PURPOSE: An image decoding method and an apparatus thereof are provided to decode information about a reference picture set which is described in a slice header depending on a type of a slice, thereby removing unnecessary reference picture set information about an intra-slice. CONSTITUTION: A decoding apparatus parses header information about a current slice (S310). The decoding apparatus decodes the current slice without constructing a reference picture set about the current slice depending on a type of the current slice based on the parsed header information (S340).
