Abstract:
An apparatus for video decoding includes processing circuitry that decodes prediction information for a current block in a current coded picture. The prediction information indicates a prediction mode that uses a motion vector predictor candidate list for reconstructing the current block. The processing circuitry includes a new motion vector predictor into the motion vector predictor candidate list. The new motion vector predictor is one of a first motion vector predictor and a second motion vector predictor. The first motion vector predictor is a first average result of a pair of existing motion vector predictors in the motion vector predictor candidate list and a temporal motion vector predictor (TMVP). The second motion vector predictor is a second average result of a pair of history-based motion vector predictors (HMVPs) in an HMVP buffer. The processing circuitry reconstructs the current block based on the motion vector predictor candidate list.
