...se computed values. I mean, how did you figure out the mean
and variance of the residual distribution? You looked at the individual
occurences of symbols and then came up with a way to represent them. The
accumulated values are represented in the mean and variance.
The whole thing is silly though. Hufffman computes symbol values.
Huffman stores the computed probabilities at the front of the stream.
(well, the first version did.. now adays the symbol probabilities are
recomputed on the fly after each symbol for speed/storage) Huffman has
been around since 1952. A whole slew of coders exist that do the...

I did some research on patent claims on range and arithmetic coding. The
original range code pdf presented in the UK by an ibm employee at the
time asserts no patent claims what so ever. If there are patents I cant
find em. I have the original paper in PDF if anyone cares to see it. Its
a good candidate for encoding because browsing a few of the
implememntations avaialable on line, I can roll my
