Abstract
Devices, systems and methods for specifying the syntax and semantics of the decoding parameter set (DPS) are described. One example method of video processing includes determining, for a conversion between a video and a bitstream of the video, that each output layer set (OLS) in a coded video sequence (CVS) in the bitstream conforms to at least one profile-tier-level (PTL) syntax structure included in a data structure associated with decoding parameter semantics in the bitstream, and performing, based on the determining, the conversion, wherein the PTL syntax structure indicates a profile, a tier, and a level of the bitstream.
Claims20
A method of video processing, comprising:
- performing a conversion between a video and a bitstream of the video,
- wherein the bitstream includes a decoding capability information syntax structure,
- wherein the decoding capability information syntax structure includes a plurality of profile-tier-level (PTL) syntax structures, wherein each of the plurality of PTL syntax structures indicates a profile, a tier, and a level of the bitstream,
- wherein the bitstream conforms to a format rule, and
- wherein the format rule specifies an exclusion of a sublayer level information from the plurality of PTL syntax structures that are included in the decoding capability information syntax structure of the bitstream.
An apparatus for processing video data comprising a processor and a non-transitory memory with instructions thereon, wherein the instructions upon execution by the processor, cause the processor to:
- perform a conversion between a video and a bitstream of the video,
- wherein the bitstream includes a decoding capability information syntax structure,
- wherein the decoding capability information syntax structure includes a plurality of profile-tier-level (PTL) syntax structures, wherein each of the plurality of PTL syntax structures indicates a profile, a tier, and a level of the bitstream,
- wherein the bitstream conforms to a format rule, and
- wherein the format rule specifies an exclusion of a sublayer level information from the plurality of PTL syntax structures that are included in the decoding capability information syntax structure of the bitstream.
A non-transitory computer-readable storage medium storing instructions that cause a processor to:
- perform a conversion between a video and a bitstream of the video,
- wherein the bitstream includes a decoding capability information syntax structure,
- wherein the decoding capability information syntax structure includes a plurality of profile-tier-level (PTL) syntax structures, wherein each of the plurality of PTL syntax structures indicates a profile, a tier, and a level of the bitstream,
- wherein the bitstream conforms to a format rule, and
- wherein the format rule specifies an exclusion of a sublayer level information from the plurality of PTL syntax structures that are included in the decoding capability information syntax structure of the bitstream.
A non-transitory computer-readable recording medium storing a bitstream of a video which is generated by a method performed by a video processing apparatus, wherein the method comprises:
- generating the bitstream of the video,
- wherein the bitstream includes a decoding capability information syntax structure,
- wherein the decoding capability information syntax structure includes a plurality of profile-tier-level (PTL) syntax structures, wherein each of the plurality of PTL syntax structures indicates a profile, a tier, and a level of the bitstream,
- wherein the bitstream conforms to a format rule, and
- wherein the format rule specifies an exclusion of a sublayer level information from the plurality of PTL syntax structures that are included in the decoding capability information syntax structure of the bitstream.
