Single reference picture list utilization for interprediction video coding

摘要

The example techniques described in this disclosure provide for an efficient manner to encode or decode a video block of a picture using a single reference picture list. The single reference picture list may include identifiers for reference picture or pictures used to encode or decode the video block. In some examples, a video encoder or decoder may encode or decode a video block that is predicted from two reference pictures using the single reference picture list, and encode or decode a video block that is predicted from one reference picture using the same, single reference picture list.

1. A method of coding video data comprising:
constructing, with a video coder, a single reference picture list that includes an identifier for each of one or more reference pictures from a memory that stores decoded reference pictures, wherein the single reference picture list, and no other reference picture list, is utilized to code a bi-predicted video block, and the same single reference picture list is utilized to code a uni-directionally predicted video block; coding, with the video coder, one index value of the single reference picture list if a video block of a current picture is uni-directionally predicted and two index values of the single reference picture list if the video block of the current picture is bi-predicted; and coding, with the video coder, the video block of the current picture using the single reference picture list, and no other reference picture list, wherein, when the video block is bi-predicted, the video block is coded with respect to two of the reference pictures identified in the single reference picture list by the two index values, and, when the video block is uni-directionally predicted, the video block is coded with respect to one of the reference pictures identified in the same single reference picture list by the one index value.
