Abstract:
Disclosed are a method and apparatus for encoding/decoding images. The image-decoding method comprises the steps of: receiving a bit stream including information regarding an NAL unit type; and checking whether or not the NAL unit in the bit stream is a reference picture based on said information regarding an NAL unit type and decoding the NAL unit. The information regarding an NAL unit type indicates whether the NAL unit is a reference reading picture or not a reference reading picture.

Claim (Index 13):
A video decoding method by a decoding apparatus, the method comprising:\n receiving, by the decoding apparatus, a bitstream; acquiring, by the decoding apparatus, network abstraction layer (NAL) unit type information and temporal identifiter (ID) information from the bitstream; determining, by the decoding apparatus, a NAL unit type of a leading picture as one of NAL unit types, based on the NAL unit type information, wherein the leading picture precedes an associated random access point picture in output order; deriving, by the decoding apparatus, a temporal ID of the leading picture based on the temporal ID information; configuring, by the decoding apparatus, a reference picture set, including RefPicSetStCurrBefore, RefPicSetStCurrAfter and RefPicSetLtCurr, for inter prediction with regard to a picture which follows the leading picture in decoding order, based on the NAL unit type and the temporal ID of the leading picture; and performing, by the decoding apparatus, the inter prediction on at least one block in the picture based on the reference picture set, wherein the NAL unit types includes a first NAL unit type representing referenced decodable leading picture and a second NAL unit type representing non-referenced decodable leading picture, and wherein the leading picture with the second NAL unit type is not included in any of the RefPicSetStCurrBefore, the RefPicSetStCurrAfter and the RefPicSetLtCurr of the picture with a same value of the temporal ID.
