摘要
An entropy encoding method includes following steps: receiving symbols of a pixel group; entropy encoding data derived from the symbols of the pixel group to generate a first bitstream portion and a second bitstream portion, wherein the first bitstream portion includes encoded magnitude data of the symbols of the pixel group, and the second bitstream portion includes encoded sign data of at least a portion of the symbols of the pixel group; and generating a bitstream segment of the pixel group by combining at least the first bitstream portion and the second bitstream portion. The pixel group includes a plurality of pixels, and the symbols of the pixel group have a plurality of symbol values of the pixels, respectively. When a first symbol value has a zero magnitude value, a sign value of the first symbol value is not entropy encoded into the second bitstream portion.
