Methods of palette mode coding in video coding
An apparatus and method of coding a palette table using a palette predictor list operate by receiving input data associated with a current block in a picture, receiving a current palette for a current block in the picture, and receiving the palette predictor list for the current palette. For a current position of the palette predictor list, the operations determine a current palette predictor run, wherein a distance between the current position of the palette predictor list and a next position of a next palette entry of the palette predictor list corresponds to the current palette predictor run. Further, the operation constrains a syntax element representing the current palette predictor run to a range of values to cause the next palette entry of the palette predictor list to be within the palette predictor list, and signal or parse the syntax element in a bitstream for the current block.
