US 12,756,820 B2 · Combined inter and intra prediction

Abstract

Systems, methods, and instrumentalities are disclosed for a combined inter and intra prediction. A video coding device may receive a motion vector difference (MMVD) mode indication that indicates whether MMVD mode is used to generate inter prediction of a coding unit (CU). The video coding device may receive a combined inter merge/intra prediction (CIIP) indication, for example, when the MMVD mode indication indicates that MMVD mode is not used to generate the inter prediction of the CU. The video coding device may determine whether to use triangle merge mode for the CU, for example, based on the MMVD mode indication and/or the CIIP indication. On a condition that the CIIP indication indicates that CIIP is applied for the CU or the MMVD mode indication indicates that MMVD mode is used to generate the inter prediction, the video coding device may disable the triangle merge mode for the CU.

Dependent claims

A device for video decoding, comprising:

a processor configured to:
obtain a combined inter merge-intra prediction (CIIP) indication that indicates whether CIIP is applied for a video block;
determine, based on the CIIP indication, that CIIP is applied for the video block;
determine that a merge mode is enabled for a picture that comprises the video block, wherein the merge mode allows a triangle partition of the video block to be predicted using a uni-prediction merge candidate associated with the video block;
determine to disable the merge mode for the video block based on determining that CIIP is applied for the video block;
and
decode the video block based on disabling the merge mode for the video block.
