Abstract: A method for video encoding includes determining an inferable condition for a flag of a specific prediction mode for a current block. The specific prediction mode is one of a plurality of inter picture prediction modes, the inferable condition is based on whether the specific prediction mode and other modes in the plurality of inter prediction modes are allowed, and the other modes are at a lower level than the specific prediction mode in a tree structure. Encoding of the flag in a video bitstream is skipped when the inferable condition indicates that the flag is inferable. The flag is encoded in the video bitstream when the inferable condition indicates uncertainty for inferring the flag. The current block is encoded according to the specific prediction mode when the flag is indicative of an application of the specific prediction mode on the current block.

Abstract: Coded information of a current block and neighboring blocks of the current block is received, where the current block is predicted in an intra directional mode. The intra directional mode of the current block is determined to be associated with an angle that is one of smaller than 90 degrees and larger than 180 degrees. In response to the intra directional mode of the current block being associated with the angle, whether a delta angle associated with the current block is a pre-defined delta angle is determined. In response to the delta angle associated with the current block not being the pre-defined delta angle, a single direction intra prediction and not a bi-direction intra prediction is applied to the current block. A sample of the current block is reconstructed based on an adjacent reference sample on a reference line that is determined according to the single direction intra prediction.

When (i) the HLS flag having a second value and (ii) at least one of the first reference block and the second reference block is at least partially outside of a corresponding reference boundary, encoding the first block using a second set of weighting factors for the reference values from the first reference block and the second reference block.

Abstract: A computing system receives a video bitstream that includes a current block and a syntax element indicating that the current block is to be predicted in a blending mode. The current block is encoded using information from first and second reference blocks. When a portion of the current block corresponds to a first area that (i) is within corresponding reference boundaries in both of the first and second reference blocks or (ii) is not within the corresponding reference boundaries in both of the first and second reference blocks, the system reconstructs the portion by averaging reference values from the first and second reference blocks. When the portion of the current block corresponds to a second area that is within the corresponding reference boundaries in only one of the first and second reference blocks, the system derives weighted reference values and reconstructs the portion by combining the weighted reference values.
