1. A method of video coding, the method comprising:
obtaining one or more reference blocks associated with a current block of a video picture, wherein the one or more reference blocks are associated with one or more previously coded pictures for predicting the current block;
determining a first weight based on a plurality of neighboring blocks of the current block in a same video picture, wherein the first weight is a CHIP weight;
generating an inter prediction based on the first weight, a left neighboring weight, a top neighboring weight, and one or more motion vectors from the current block to the one or more reference blocks;
generating a position dependent intra prediction combination (PDPC)-based intra prediction based on a left neighboring reconstructed reference sample of a plurality of neighboring reconstructed reference samples, a top neighboring reconstructed reference sample of the plurality of neighboring reconstructed reference samples, the first weight, the left neighboring weight and the top neighboring weight, wherein the plurality of neighboring reconstructed reference samples are associated with the plurality of neighboring blocks of the current block in the same video picture; and
generating a final prediction based on the PDPC-based intra prediction, the inter prediction and the first weight.
