Patent attributes
Techniques described herein are related to coding layer identifiers for operation points in video coding. In one example, a method of decoding video data is provided. The method comprises decoding syntax elements in a video parameter set (VPS) within a conforming bitstream indicating a first operation point having a first set of content. The method further comprises decoding, if present, syntax elements in the VPS within the conforming bitstream indicating hypothetical reference decoder (HRD) parameter information having a second set of content for the first operation point, wherein the conforming bitstream does not include syntax elements in the VPS that duplicate at least one of the first or second set of content for a second operation point, and wherein decoding syntax elements comprises decoding the syntax elements indicating the first operation point and the HRD parameter information only within conforming bitstreams.
