  • Publication number: 20210321089
    Abstract: A method and apparatus of video coding using history-based candidate derivation are disclosed. According to one method, a current block is inside a Shared Merge candidate list Region (SMR) or a history-based parallel processing region is received. The current block is encoded or decoded using a Merge candidate list. Only if the current block is one of first-coded N (N?0) blocks, one of last-coded N blocks, or one of selected N blocks, the history-based candidate list is updated after the current block is encoded or decoded. In one embodiment, Merge candidate list is pre-generated for the current block in the SMR and is separately generated for the current block in the history-based parallel processing region. In another method, if the current block is inside the SMR or the history-based parallel processing region, the current block is encoded or decoded using a history-based candidate list associated with the root CU.

  • Patent number: 11115653
    Abstract: A method for generating a list of merge candidates for Intra Block Copy (IBC) prediction is provided. A video codec receives data to be encoded or decoded as a current block of a current picture of a video. A plurality of spatially adjacent neighboring blocks of the current block are coded before the current block. The video codec generates a list of merge candidates including intra picture candidates that are associated with motion information referencing pixels in the current picture. The intra picture candidates comprises candidates that are associated with some but not all of the two or more spatially adjacent neighboring blocks of the current block. The video codec selects a merge candidate from the generated list. The video codec encodes or decodes the current block by using the motion information of the selected merge candidate to generate a prediction of the current block.
