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 the steps of:
- obtaining a first flag indicating whether a current picture includes subpictures having different network abstraction layer (NAL) unit types;
- and
- obtaining a second flag indicating whether the subpicture is treated as a picture in a decoding process, wherein
- when the first flag indicates that the current picture includes subpictures having different NAL unit types, the second flag for a subpicture having a NAL unit type equal to RADL (Random Access Decodable Leading) among the subpictures is restricted to have a first value, and
- the first value indicates that the subpicture is treated as a picture in a decoding process.
