Abstract
This disclosure relates generally to video coding and particularly to methods and systems for signaling of compound inter prediction modes. For example, a correlation between a use of optical flow refinement and various compound inter prediction modes is explored to design example schemes for signaling an optical flow refinement flag and a compound inter prediction mode for a video block. Specifically, the signaling of the inter prediction modes for a block may depend on whether the optical flow refinement is applied to the block or not.
