  • Patent number: 10869031
    Abstract: A method of IntraBC coding using restricted reference area is disclosed. A reference block is selected from an available ladder-shaped reference area comprising previously processed blocks before the current working block in the current CTU row and previously processed blocks in one or more previous CTU rows. A location of a last previously processed block of a second previous CTU row that is one CTU row farther away from the current CTU row than a first previous CTU row is always in a same vertical location or after a same vertical position of a last previously processed block of the first previous CTU row. The current picture may be partitioned into multiple CTU rows for applying wavefront parallel processing (WPP) on the multiple CTU rows, where the current working block corresponds to a current working block. Similar restrictions may also be applied to slice/tile-based parallel processing.

  • Patent number: 10750203
    Abstract: Method and apparatus of video coding using generalized bi-prediction are disclosed. According to one method, the generalized bi-prediction is extended for Decoder-Side Motion Vector Refinement (DMVR), where unequal weighting factor pair is allowed to form the template of the current block or the final predictor. In another method, the generalized bi-prediction is extended to pattern-based MV derivation (PMVD), where unequal weighting factor pair is allowed to combined reference blocks pointed by motion vectors derived based on PMVD. In yet another method, the generalized bi-prediction is used for Merge mode. When the final Merge MVP selected corresponds to bi-prediction using an unequal weighting factor pair, a new weighting factor pair is derived using neighboring reconstructed pixels of the current block and corresponding motion compensated pixels. In yet another method, the size of a set of weighting factor pairs is dependent on block size.
