Abstract
A video coding device may identify a network abstraction layer (NAL) unit. The video coding device may determine whether the NAL unit includes an active parameter set for a current layer. When the NAL unit includes the active parameter set for the current layer, the video coding device may set an NAL unit header layer identifier associated with the NAL unit to at least one of: zero, a value indicative of the current layer, or a value indicative of a reference layer of the current layer. The NAL unit may be a picture parameter set (PPS) NAL unit. The NAL unit may be a sequence parameter set (SPS) NAL unit.
