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.
