摘要： A method and apparatus for deriving a motion vector predictor (MVP) are disclosed. The MVP is selected from spatial MVP and temporal MVP candidates. The method uses a flag to indicate whether temporal MVP candidates are disabled. If the flag indicates that the temporal MVP candidates are disabled, the MVP is derived from the spatial MVP candidates only. Otherwise, the MVP is derived from the spatial and temporal MVP candidates. The method may further skip spatial redundant MVP removal by comparing MV values. Furthermore, the parsing error robustness scheme determines a forced temporal MVP when a temporal MVP is not available and the temporal MVP candidates are allowed as indicated by the flag. The flag may be incorporated in sequence, picture, slice level, or a combination of these levels.

摘要： The invention provides a motion prediction method. First, a plurality of motion vector predictors is obtained to be included in a candidate set for motion prediction of a current unit of a current frame. Whether the current frame is a non-reference frame which is not referred to by other frames for motion prediction is then determined. When the current frame is not the non-reference frame, any motion vector predictor corresponding to a previously coded frame is removed from the candidate set, and a motion vector of the current unit is predicted according to the motion vector predictors of the candidate set.

摘要： A method and apparatus for deriving a temporal motion vector predictor (MVP) are disclosed. The MVP is derived for a current block of a current picture in Inter, or Merge, or Skip mode based on co-located reference blocks of a co-located block. The co-located reference blocks comprise an above-left reference block of the bottom-right neighboring block of the co-located block. The reference motion vectors associated with the co-located reference blocks are received and used to derive the temporal MVP. Various configurations of co-located reference blocks can be used to practice the present invention. If the MVP cannot be found based on the above-left reference block, search for the MVP can be continued based on other co-located reference blocks. When an MVP is found, the MVP is checked against the previously found MVP. If the MVP is the same as the previously found MVP, the search for MVP continues.

摘要： A method and apparatus for deriving MV/MVP (motion vector or motion vector predictor) or DV/DVP (disparity vector or disparity vector predictor) associated Skip mode, Merge mode or Inter mode for a block of a current picture in three-dimensional (3D) video coding are disclosed. The 3D video coding may use temporal prediction and inter-view prediction to exploit temporal and inter-view correlation. MV/DV prediction is applied to reduce bitrate associated with MV/DV coding. The MV/MVP or DV/DVP for a block is derived from spatial candidates, temporal candidates and inter-view candidates. For the inter-view candidate, the position of the inter-view co-located block can be located using a global disparity vector (GDV) or warping the current block onto the co-located picture according to the depth information. The candidate can also be derived as the vector corresponding to warping the current block onto the co-located picture according to the depth information.

摘要： An apparatus and method for motion vector prediction for a current block in a picture are disclosed. In video coding systems, the spatial and temporal redundancy is exploited using spatial and temporal prediction to reduce the information to be transmitted. Motion Vector Prediction (MVP) has been used to further conserve the bitrate associated with motion vector. In conventional temporal MVP, the predictor is often based on a single candidate such as the co-located motion vector in the previous frame/picture. If the co-located motion vector in the previous frame/picture does not exist, the predictor for the current block is not available. A technique for improved MVP is disclosed where the MVP utilized multiple candidates based on co-located motion vectors from future and/or past reference pictures. The candidates are arranged according to priority order to provide better availability of MVP and also to provide more accurate prediction. Furthermore, the MVP technique disclosed can be operated in a closed-loop fashion so that no additional side information or minimum additional side information is required.

摘要： An apparatus and method for deriving a motion vector predictor are disclosed. A search set comprising of multiple (spatial, or temporal) search MVs with priority is determined, wherein the search MVs for multiple neighboring reference block or one or more co-located reference blocks are configured into multiple search MV groups. In order to improve coding efficiency, embodiments according to the present invention, perform redundancy check every time after a search MV group is searched to determine whether an available search MV found. If an available search MV is found and the available search MV is not the same as a previously derived motion vector predictor (MVP), the available search MV is used as the MVP and the MVP derivation process terminates. Otherwise, the MVP derivation process moves to the next reference block. The search MV group can be configured to include different search MV(s) associated with reference blocks.
