Abstract: In response to a current block being partitioned into a first partition and a second partition based on a geometric partition mode, a first prediction type for the first partition and a second prediction type for the second partition are determined based on a flag associated with one of intra prediction, inter prediction, and intra block copy (IBC). Each of the first and second prediction types is one of the intra prediction, the inter prediction, and the IBC. Based on the first prediction type, a first prediction mode for the first partition of the current block is determined. Based on the second prediction type, a second prediction mode for the second partition of the current block is determined. The first partition of the current block is reconstructed based on the first prediction mode and the second partition of the current block is reconstructed based on the second prediction mode.
