Reference picture set prediction for video coding

摘要

In one example, a device for decoding video data includes a video decoder configured to decode one or more syntax elements of a current reference picture set (RPS) prediction data structure, wherein at least one of the syntax elements represents a picture order count (POC) difference between a POC value associated with the current RPS and a POC value associated with a previously decoded RPS, form a current RPS based at least in part on the RPS prediction data structure and the previously decoded RPS, and decode one or more pictures using the current RPS. A video encoder may be configured to perform a substantially similar process during video encoding.

1. A method of decoding video data, the method comprising:
decoding one or more syntax elements of a current reference picture set (RPS) prediction data structure, wherein at least one of the syntax elements represents a picture order count (POC) difference between a POC value associated with a current RPS and a POC value associated with a previously decoded RPS, and wherein at least one of the syntax elements represents at least one reference picture to be included in the current RPS that is not included in the previously decoded RPS; forming the current RPS, wherein forming the current RPS comprises predicting the current RPS using the previously decoded RPS to form a predicted RPS, and adding an identifier of the at least one reference picture that is to be included in the current RPS and that is not included in the previously decoded RPS to the predicted RPS; and decoding one or more pictures using the current RPS.
