The apparatus at an encoding end includes a memory storage and a processor coupled to the memory that executes the instructions to perform quantization using a coefficient matrix on an image, the coefficient matrix having a plurality of coefficients which being divided into a plurality of frequency bands, wherein a number of the frequency bands is smaller than a number of coefficients in the coefficient matrix; a scaling value is assigned that every coefficient in said each frequency band has the same scaling value; generate a parameter set having multiple band parameters thereof and write the parameter set into a bitstream to be transmitted.
