METHOD AND APPARATUS FOR IMAGE ENCODING/DECODING

摘要

Disclosed are a method and an apparatus for image encoding/decoding. The image decoding method which supports a plurality of layers according to the present invention comprises the steps of: receiving a bitstream including inter-layer switching time information that indicates whether inter-layer switching from a first layer to a second layer is possible; and decoding the bitstream based on the inter-layer switching time information. The inter-layer switching time information includes information on the layer switching picture (LSP) of the time when inter-layer switching is possible. The information on the layer switching picture is induced from the network abstraction layer (NAL) unit type parsed from the bitstream.
