Abstract
A system for decoding a video bitstream includes receiving a frame of the video that includes at least one slice and at least one tile and where each of the at least one slice and the at least one tile are not all aligned with one another.
Claims5
A method for decoding a coded video sequence comprising:
- receiving a bitstream corresponding to coded pictures of said coded video sequence;
- receiving a video syntax set that includes information applicable to said coded video sequence;
- determining, based on a flag included in said video syntax set, whether a scalability dimension identifier is implicitly signaled;
- wherein said scalability dimension identifier specifies a scalability dimension of a layer of said coded video sequence;
- in response to determining that the scalability dimension identifier is implicitly signaled, deriving the scalability dimension identifier from a network abstraction layer (NAL) unit header;
- decoding a base layer of a picture in the video sequence, wherein decoding the base layer comprises motion compensation.
