ABSTRACT:
An encoding and decoding apparatus and method which has the primary benefit over the prior art of not requiring storage of the nonlinear sequence of numbers representative of the quantization characteristics. The hardware required for quantization is reduced and inverse quantization may be achieved using shifting operations and a multiplier of up to half the scale compared to conventional encoding/decoding methods and encoding/decoding apparatus.
