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.
