摘要

Our proposal in this paper fills the gap left by Shannon's theory of lossy compression (rate distortion theory), and, indeed, exposes the inadequacies of that theory by showing that globally meaningful objects can, and commonly do, have rate distortion characteristics that are radically different from those supplied by Shannon's approach.rnThe Apple iPOD webpage states: "iTunes makes it easy to quickly transfer your favorite songs and albums. Just pop a CD into your Mac or PC and click the Import button. You can import music in a variety of formats, such as MP3 or AAC, and at whatever quality level youd prefer. You can even choose the new Apple Lossless encoder. Music encoded with that option offers sound quality indistinguishable from the original CDs at about half the file size of the original."
