Distro + entropy code[edit]

A Canonical Huffman code as opposed to a Red Hat range code? What about a Gentoo Foundation gamma code, given the power law distribution of word frequencies? -- 20:47, 25 April 2012 (MST)

Not that Canonical, and not that universal code either. I've used gamma codes before for run-lengths in one of my NES-based image codecs. But in the case of Huffword, replacing the table of counts per length with a fixed universal code might save a little space in the decoder, but the difference between the size of a generic Exp-Golomb decoder (of which gamma is a special case) and the size of the first half of a CH decoder is probably minuscule. Most of the space in a CH decoder model is in the table from symbols to indices, and a universal code won't save any on that. In fact, Huffword uses two layers of CH: one for words and one for characters in the dictionary. --Tepples 20:59, 25 April 2012 (MST)
