The illustration of how narrow the intersection of the multiple QCSs depends not only on the relation among the sizes of QCSs from multiple compressed copies, but also the position of the QCSs' intervals. A narrower QCS cannot be obtained when the quantization step sizes of Copies 1 and 2 are too large compared with that of Copy 3.The relative position of each QCS that is partly determined by the prediction value may help to reduce the size of the narrow QCS.
