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.
Claims9
An image decoding method, the method comprising:
- receiving, by a decoding apparatus, a bitstream;
- acquiring, by the decoding apparatus, information indicating a network abstraction layer (NAL) unit type 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 information indicating the NAL unit type, wherein the leading picture precedes an associated random access point picture in output order;
- configuring, by the decoding apparatus, a reference picture list to perform inter prediction with regard to a picture which follows the leading picture in decoding order, based on the NAL unit type 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 list,
- 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.
