Abstract: A method of bi-predictive Inter prediction mode using a uni-predictive motion vector and a second motion vector associated with a Merge candidate is disclosed. In the encoder side, the coded motion information for a uni-prediction motion vector for the current block is generated using a motion vector predictor selected from a motion vector prediction (MVP) candidate list. Furthermore, a Merge candidate with a second motion vector pointing to the other prediction direction is identified according to a Merge index. The uni-prediction motion vector and the second motion vector from the Merge candidate are used for bi-prediction encoding of the current block. In the decoder side, the corresponding decoding process is disclosed.

Abstract: A method and apparatus for deriving motion compensated prediction for boundary pixels in a video coding system are disclosed. Embodiments of the present invention determine a current motion vector (MV) and one or more neighboring MVs corresponding to an above MV, a left MV, or both the above MV and the left MV. A first predictor for a current boundary pixel in a boundary region of the current CU is generated by applying motion compensation based on the current MV and a first reference picture pointed by the current MV. One or more second predictors for the current boundary pixel are generated by applying the motion compensation based on the neighboring MVs and reference pictures pointed by the neighboring MVs. A current boundary pixel predictor for the current boundary pixel is then generated using a weighted sum of the first predictor and the second predictors according to weighting factors.
