Sounds like fancy talk for the (now) common process of creating a master at 20/24-bit resolution and downsampling & dithering (aka "noise shaping")for 16-bits. Sony calls it "Super Bit Mapping (SBM)", EMI has "ART", BMG has UV22, and DG calls theirs "Original Image Bit Processing". The algorithms, names, patents, etc. may be slightly different, but they do essentially the same thing - add a small ammount of controlled noise to a digital signal to help improve low level sound resolution, then "mapping" or "shaping" the noise out of hearing range.
