It's easily covered. Check usenet comp.compression faq. It's the "Counting Theorem". For a sequence of n-bits there are 2^n possible files (f.e. there are 256 files of 8 bits). Unfortunately there are only (2^n)-1 possible files lesser than the original (f.e. there are 128 files of 7 bits, 64 of 6, 32 of 5, 16 of 4, 8 of 3, 4 of 2 and 2 of 1 bits, total, 255 files) so using an algorithm you can't compress all n-bits sequences. For this case, you can easily check that using this guy algorithm, you can have only 2^8192 movies. Perhaps you think they are a lot, but nearly all are white noise movies. There are 1-2 monthly of this claims on comp.compression. Normally they are beginners to Information Theory / Compression but others are simply cheaters. >sounds a lot like the perpetuum mobile stories. In fact, it is. Information Theory uses entropy concept too and claims like this breaks the 2nd and 3rd principle. >>But this is the >> kind of leap forward that would save, oh, a few measley >> $Billions. And give millions of us faster and broader access.
