Scalable extensions to HEVC and temporal motion vector prediction |
摘要 |
In one example, a device includes a video coder configured to determine a first co-located reference picture for generating a first temporal motion vector predictor candidate for predicting a motion vector of a current block, determine a second co-located reference picture for generating a second temporal motion vector predictor candidate for predicting the motion vector of the current block, determine a motion vector predictor candidate list that includes at least one of the first temporal motion vector predictor candidate and the second temporal motion vector predictor candidate, select a motion vector predictor from the motion vector predictor candidate list, and code the motion vector of the current block relative to the selected motion vector predictor. |

1. A method of decoding video data, the method comprising:
determining, by one or more processors, a first co-located reference picture in a first layer for generating a first temporal motion vector predictor candidate for predicting a motion vector of a current block of a current picture of the first layer; determining, by the one or more processors, a second co-located reference picture in a second layer of video data that is different from the first layer for generating a second temporal motion vector predictor candidate for predicting the motion vector of the current block of the current picture of the first layer; determining, by the one or more processors, a motion vector predictor candidate list that includes at least one of the first temporal motion vector predictor candidate and the second temporal motion vector predictor candidate; selecting, by the one or more processors, a motion vector predictor from the motion vector predictor candidate list; and decoding, by the one or more processors, the motion vector of the current block relative to the selected motion vector predictor. |
