Abstract
Systems, methods, and computer-readable storage media for maintaining palette predictors for palette coding are described. An example method can include determining a current palette coding block of a single tree coded slice of a picture is encoded according to a local dual tree; determining, after an update of a palette predictor associated with the current palette coding block, a first number of palette predictor entries for a first image component of the current palette coding block and a second number of palette predictor entries for a second image component of the current palette coding block; determining the first number of palette predictor entries is greater than the second number of palette predictor entries; and based on the first number being greater than the second number, modifying the updated palette predictor to include a same number of palette predictor entries for the first and second image component.
