Abstract

A video coding or decoding method includes using history-based motion vectorprediction (HMVP) for conversion between multiple video blocks including a current block ofvideo and a bitstream representation of the multiple video blocks such that for a uni-predictedblock that for which a single reference picture is used for motion compensation, refraining fromupdating a look-up table for HMVP candidates for the uni-predicted block. The video coding ordecoding method further includes performing the conversion using look-up tables for themultiple video blocks.
