17 Claims

1. A method for video decoding in a decoder, comprising:

decoding prediction information of a current block from a coded video bitstream, the prediction information indicating that a prediction of the current block is at least partially based on an inter prediction;

receiving a first flag for an intra-inter prediction mode that uses a combination of an intra prediction and the inter prediction of the current block;

excluding a motion refinement based on a bi-directional optical flow (BDOF) mode from the inter prediction of the current block;

decoding, when the first flag indicates true for the intra-inter prediction mode, a second flag that is indicative of a usage of a position dependent prediction combination (PDPC) on the inter prediction; and

reconstructing a sample of the current block based on the PDPC on the inter prediction.
