摘要： A method and apparatus for encoding a video sequence comprising a plurality of pictures are disclosed. In video coding systems, the temporal redundancy is exploited using motion compensated prediction. The video sequence is often organized into multiple GOP (group of pictures) where different types of GOP may be used. In conventional coding systems, IPPP and IBBP GOP structure is often used. In H.264/AVC and the emerging High Efficiency Video Coding (HEVC), hierarchical GOP structure, including hierarchical P GOP structure and hierarchical B GOP structure, has been introduced to allow temporal scalability. Furthermore, low-delay IBBB GOP structure has been also introduced, for low-delay application. In the present invention, a low-delay hierarchical B GOP structure is disclosed. The new structure uses low-delay B-pictures only so as to minimize the processing delay while the hierarchical structure provides the temporal scalability. The low-delay hierarchical B GOP structure has been shown to result in substantial improvement in coding efficiency.

摘要： An apparatus and method for deriving a motion vector predictor (MVP) or a MVP candidate for a current block are disclosed. Embodiments according of the present invention receive a first motion vector associated a first reference picture in a first reference picture list and a second motion vector associated with a second reference picture in a second reference picture list of a spatially neighboring block. A MVP or at least one MVP candidate associated with a selected reference picture in a selected reference picture list for the current block is then determined based on the first reference picture, the second reference picture and the selected reference picture according to a pre-defined priority order. The MVP or MVP candidate is determined depending on whether the first reference picture is the same as the selected reference picture or whether the second reference picture is the same as the selected reference picture.

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 arc 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.
