Abstract
The present invention discloses a video decoding method performed by a video decoding device. The video decoding method according to an embodiment may include the steps of: obtaining NAL unit type information indicating a type of a current network abstraction layer (NAL) unit from a bitstream; and decoding, when the NAL unit type information indicates that the NAL unit type of the current NAL unit is an encoded data for an slice, the slice based on whether a mixed NAL unit type is applied to a current picture.
Claims7
A video decoding method performed by a video decoding device, the method comprising:
- receiving a bitstream;
- obtaining, from the bitstream, a first flag indicating whether a current picture includes subpictures having different network abstraction layer (NAL) unit types;
- and
- obtaining, from the bitstream, second flags, each of the second flags is associated with a respective one of the subpictures, wherein
- each of the second flags indicates whether an associated subpicture is treated as a picture in a decoding process,
- when the first flag indicates that the current picture includes subpictures having different NAL unit types, second flags for all subpictures having a NAL unit type equal to RASL (Random Access Skipped Leading) among the subpictures are restricted to have a first value regardless of whether each subpicture whose NAL unit type is equal to RASL is referenced, and
- the first value indicates that the associated subpicture is treated as a picture in a decoding process.
