OPTIMIZATIONS ON INTER-LAYER PREDICTION SIGNALING FOR MULTI-LAYER VIDEO CODING

摘要

A method of coding video data includes receiving one or more layers of video information. Each layer may include at least one picture. The method can include determining a number of active reference layer pictures associated with at least one picture of the one or more layers. The method can further include determining a number of direct reference layers associated with the at least one of the one or more layers. Based on the number of direct reference layers equaling the number of active reference layer pictures, the method can further include refraining from further signaling inter-layer reference picture information in any video slice associated with at least one of a video parameter set (VPS), a sequence parameter set (SPS), or a picture parameter set (PPS). Additionally or alternatively, based on the number of direct reference layers equaling the number of active reference layer pictures, the method can include adding to the inter-layer reference picture set all direct reference layer pictures for any video slice associated with at least one of a video parameter set (VPS), a sequence parameter set (SPS), or a picture parameter set (PPS).
