    Abstract: Techniques and systems are provided for encoding and decoding video data. For example, a method of decoding video data includes obtaining an encoded video bitstream comprising one or more layer sets and one or more additional layer sets. Each of a layer set and an additional layer set includes one or more layers. The encoded video bitstream includes a video parameter set defining parameters of the encoded video bitstream. The one or more layer sets are defined in a base part of the video parameter set, and the one or more additional layer sets are defined in an extension part of the video parameter set. The method further includes decoding one or more syntax elements from the video parameter set. The one or more syntax elements include rate information for the one or more layer sets defined in the base part of the video parameter set and for the one or more additional layer sets defined in the extension part of the video parameter set.

    Abstract: A video processing device is configured to obtain, from a bitstream, one or more syntax elements indicating one or more partitioning schemes for an output layer set. For each respective partitioning scheme of the one or more partitioning schemes, the respective partitioning scheme specifies a division of the output layer set into one or more partitions. Each layer in the output layer set belongs to exactly one partition in the respective partitioning scheme. Additionally, the video processing device obtains, from a Supplemental Enhancement Information (SEI) message or video usability information (VUI) in a video parameter set (VPS), hypothetical reference decoder (HRD) parameters for each of the one or more partitioning schemes. For each respective partition of the respective partitioning scheme, the video processing device tests, based on the HRD parameters for the respective partitioning scheme, the respective partition for conformance to a video coding standard.

    Abstract: In an example, a method of coding video data includes obtaining one or more video coding layer (VCL) network abstraction layer (NAL) units of an access unit and a first layer of a multi-layer bitstream of video data. The method also includes only coding one or more non-VCL NAL units containing an SEI message applicable to the VCL NAL units of the first layer together with the VCL NAL units of the first layer such that within the access unit the bitstream does not contain any coded pictures of any other layer of the multi-layer bitstream between the VCL NAL units of the first layer and the non-VCL NAL units containing the SEI message applicable to the VCL NAL units of the first layer.

The memory is configured to store video information associated with a bitstream. The apparatus further includes a processor in communication with the memory, the processor configured to determine that a reference layer is not included in the bitstream. The processor is further configured to receive, from an external source, a decoded base layer picture associated with an access unit, to store the decoded base layer picture in a memory.
