Abstract

A method and apparatus is disclosed herein for quantizing data using a perceptually relevant search of multiple quantization patterns. In one embodiment, the method comprises performing a perceptually relevant search of multiple quantization patterns in which one of a plurality of prototype patterns and its associated permutation are selected to quantize the target vector, each prototype pattern in the plurality of prototype patterns being capable of directing quantization across the vector; converting the one prototype pattern, the associated permutation and quantization information resulting from both to a plurality of bits by an encoder; and transferring the bits as part of a bit stream.
