    Abstract: In one example, a device for coding (e.g., encoding or decoding) video data includes a memory configured to store video data, and a video coder configured to code hypothetical reference decoder (HRD) parameters for each sub-layer of each bitstream partition of a video bitstream; and process the video bitstream using the HRD parameters. The video coder may code the HRD parameters in the form of a loop over the HRD parameters that is iterated for each of the sub-layers, and/or indexes to respective sets of HRD parameters for each of the sub-layers.

The encoded video bitstream including a parameter set defining parameters of the encoded video bitstream. The method further includes determining one or more parameters of the parameter set that include information describing a first sub-bitstream of the encoded video bitstream that includes one or more layers with video data and information describing a second sub-bitstream of the encoded video bitstream that includes one or more layers with no video data. The method further includes performing a bitstream conformance check on the first sub-bitstream or the second sub-bitstream based on whether at least one layer of the first sub-bitstream or the second sub-bitstream includes video data.

    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 video encoder generates a Network Abstraction Layer (NAL) unit that contains a plurality of encoded picture partitions of the video data. The video encoder generates a bitstream that includes a variable-length value that represents an entropy-encoded first syntax element, a variable-length value that represents an entropy-encoded second syntax element, and fixed-length values that represent offset syntax elements. Lengths of each of the offset syntax elements are determinable based on the first syntax element. A video decoder uses the first syntax element, the second syntax element, and the offset syntax elements when decoding the encoded picture partitions.
