US Patent 11284069 Harmonized local illumination compensation and modified inter prediction coding

A video processing method is provided to include: determining to use a rule that specifies that at most a single coding tool from a set of coding tools is used for a conversion between a current block of a video comprising multiple pictures and a coded representation of the video, and performing the conversion based on the rule. The set of coding tools includes coding tools that modify a reconstructed block of the current block generated from motion information from the coded representation or an inter prediction signal generated for the current block during the conversion.
