Abstract: A device determines, based at least in part on a syntax element in a scalable nesting supplemental enhancement information (SEI) message encapsulated by an SEI Network Abstraction Layer (NAL) unit, whether a nested SEI message encapsulated by the scalable nesting SEI message is applicable to a default sub-bitstream. The default sub-bitstream is an operation point representation of an operation point defined by a layer identifier specified in a NAL unit header of the SEI NAL unit and a temporal identifier specified in the NAL unit header. When the nested SEI message is applicable to the default sub-bitstream, the device uses the nested SEI message in an operation on the default sub-bitstream.

Abstract: A device performs a hypothetical reference decoder (HRD) operation that determines conformance of a bitstream to a video coding standard or determines conformance of a video decoder to the video coding standard. As part of performing the HRD operation, the device determines a highest temporal identifier of a bitstream-subset associated with a selected operation point of the bitstream. Furthermore, as part of the HRD operation, the device determines, based on the highest temporal identifier, a particular syntax element from among an array of syntax elements. The device then uses the particular syntax element in the HRD operation.

Abstract: In some examples, a video encoder includes multiple sequence parameter set (SPS) IDs in an SEI message, such that multiple active SPSs can be indicated to a video decoder. In some examples, a video decoder activates a video parameter set (VPS) and/or one or more SPSs through referencing an SEI message, e.g., based on the inclusion of the VPS ID and one or more SPS IDs in the SEI message. The SEI message may be, as examples, an active parameter sets SEI message or a buffering period SEI message.

Abstract: A device performs a decoding process as part of a bitstream conformance test. As part of the decoding process, the device performs a bitstream extraction process to extract, from a bitstream, an operation point representation of an operation point defined by a target set of layer identifiers and a target highest temporal identifier. The target set of layer identifiers contains values of layer identifier syntax elements present in the operation point representation, the target set of layer identifiers being a subset of values of layer identifier syntax elements of the bitstream. The target highest temporal identifier is equal to a greatest temporal identifier present in the operation point representation, the target highest temporal identifier being less than or equal to a greatest temporal identifier present in the bitstream. The device decodes network abstraction layer (NAL) units of the operation point representation.
