Abstract: Video processing methods and apparatuses in a video encoding or decoding system for processing a video picture partitioned into blocks with one or more partition constraints. The video encoding or decoding system receives input data of a current block and checks whether a predefined splitting type is allowed to partition the current block according to first and second constraints. The first constraint restricts each sub-block partitioned from the current block to be completely contained in one pipeline unit, and the second constraint restricts each sub-block partitioned from the current block to contain one or more complete pipeline units. The pipeline units are non-overlapping units in the video picture designed for pipeline processing. The current block is not partitioned by the predefined splitting type if any sub-block partitioned by the predefined splitting type violates both the first and second constraints. The system encodes or decodes the current block.

If an MH mode is used for the current block: at least one MH candidate is derived using reduced reference data by adjusting at least one coding-control setting; an Inter candidate list is generated, where the Inter candidate list comprises said at least one MH candidate; and current motion information associated with the current block is encoded using the Inter candidate list at the video encoder side or the current motion information associated with the current block is decoded at the video decoder side using the Merge candidate list. The coding control setting may correspond to prediction direction setting, filter tap setting, block size of reference block to be fetched, reference picture setting or motion limitation setting.

Abstract: A method of video coding using generalized bi-prediction (GBi) receives input data associated with a current block in a current picture, wherein the input data comprises information associated with a block size of the current block, determines a set of weighting factor pairs, wherein a size of the set of weighting factor pairs depends on the block size of the current block, and derives a set of advanced motion vector prediction (AMVP) candidate lists comprising MVP (motion vector prediction) candidates. The method further derives a set of final motion information based on the MVP candidates, determines that the set of final information comprises a bi-prediction predictor, generates a final predictor by combining two reference blocks associated with the final motion information using a target weighting factor pair selected from the set of weighting factor pairs, and encodes or decoding the current block using the final predictor.
