Defosse 20:1 file compression codec?

[Chip McDonald]

There's a guy in Belgium apparently claiming to have created a 20:1 video codec: http://www.cdfreaks.com/news2.php3?ID=2990 The comments to this made me think of a possible angle to compression I don't think people have thought about yet using a reductionist pictogram set. Instead of Linkwitz-Riley encoding schemes, eliminating redundancy or throwing out undifferentiated coded data, using customized coded pictograms based on common reductions of graphic arrays. Sort of like the way you had to do graphics on the old TRS-80's, using an ASCI code yielding a multi-pixel graphic from one 2 bit number. Interpolate that, THEN do typical redundant compression. I suppose the audio equivalent would be wave synthesis. You only had 128 elements of what amounted to I think 6x4 pixel arrays back then, but with modern amounts of memory being cheap you could store a huge lookup table. Throw in some vector optimized patterns based on a routine check of what the imagery looks like, use some fractal tricks for edge aliasing, interpolate color seperations. Color would still be a resource hog I think, but a lookup table of say 1,000 basic 20x20 pictograms could maybe recreate most images with some clever edge aliasing tricks. I assume MPEG compression already uses a lookup table and makes assumptions on what to throw out instead of how to reduce something to an interpolation of a set of pictograms? ?
