Patent ID: 8725504

Claim:
A method of performing inverse quantization on a quantized integral value, comprising: determining whether said quantized integral value is within a first range of possible values or a second range of possible values; calculating, within an electronic system, an interpolated inverse quantization value from said quantized integral value, wherein said calculating comprising bit shifting said quantized integral value a first predetermined number of bits when said quantized integral value is within said first range of possible values and said calculating comprising bit shifting said quantized integral value a second predetermined number of bits when said quantized integral value is within said second range of possible values, wherein said calculating comprises calculating a first intermediary value by bit shifting said quantized integral value at least one of said first predetermined number of bits and said second predetermined number of bits, and wherein said interpolated inverse quantization value is determined based on an offset accessed from a data source based on said quantized integral value; and calculating a second intermediary value from said quantized integral value and said first intermediary value.
