Patent attributes
In one example, a device includes a video coder (e.g., a video encoder or a video decoder) configured to code parameter set information for a video bitstream, code video data of a base layer of the video bitstream using the parameter set information, and code video data of an enhancement layer of the video bitstream using at least a portion of the parameter set information. The parameter set information may include, for example, profile and level information and/or hypothetical reference decoder (HRD) parameters. For example, the video coder may code a sequence parameter set (SPS) for a video bitstream, code video data of a base layer of the video bitstream using the SPS, and code video data of an enhancement layer of the video bitstream using at least a portion of the SPS, without using any other SPS for the enhancement layer.
