Abstract: Disclosed are a method and an apparatus for encoding/decoding an image. The image decoding method supporting a plurality of layers according to the present invention includes the steps of: receiving a bit stream including interlayer switching time point information representing whether it is possible to switch from a first layer to a second layer; and decoding the bit stream based on the interlayer switching time point information. The interlayer switching time point information includes information about a layer switching picture (LSP) of an interlayer switchable time point, and the LSP information is induced from a network abstraction layer (NAL) unit type parsed from the bit stream. [Reference numerals] (S1000) Receive a bit stream including interlayer switching time point information representing whether it is possible to switch from a first layer to a second layer; (S1010) Decode the bit stream based on the interlayer switching time point information

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).
