Scalable and perceptually ranked signal coding and decoding

摘要: A method and system for encoding decoding an input signal in relation to the most perceptually relevant aspects of signal. two-dimensional (2D) transform is applied produce a magnitude matrix phase that can be inverse quantized by decoder. first column coefficients represents mean spectral density (MSD) function Relevant MSD are encoded at beginning data packet. The also processed through core perception model determine bit allocation. matrices then priority ordered into packet, with least information end packet so it may ignored or truncated scalability channel rate capacity.
