ANS coding replacing Huffman and AC---from introduction to patent issues

This talk is titled "ANS coding replacing Huffman and AC -- from introduction to patent issues," and was presented at LibrePlanet 2022 by Jarek Duda.

Jarek is an Assistant Professor with Jagiellonian University. Jarek will be joined by Jozef Halbesztadt.

This talk is about ANS and the patent vultures it has attracted. The ANS coding family, which in recent years is replacing Huffman and arithmetic coding in data compressors, is currently used, for example, in the Linux kernel, default DNA compression, products of Apple, Facebook, Google, and many others like JPEG XL.

libreplanet.org

LibrePlanet is the Free Software Foundation's annual conference. The FSF campaigns for free/libre software, meaning it respects users' freedom and community. We believe that users are entitled to this; all software should be free.

We do not advocate "open source".

That term was coined to reject our views. It refers to similar practices, but usually presented solely as advantageous, without talking of right and wrong.

gnu.org/not-open-source

Richard Stallman launched the free software movement in 1983 by announcing development of the free operating system, GNU. By 1992, GNU was nearly operational; one major essential component was lacking, the kernel.

In 1992, Torvalds freed the kernel Linux, which filled the last gap in GNU. Since then, the combined GNU/Linux system has run in millions of computers. Nowadays you can buy a new computer with a totally free GNU/Linux system preinstalled.

The views of the speaker may not represent the Free Software Foundation. The Foundation supports the free software cause and freedom to share, and basic freedoms in the digital domain, but has no position on other political issues.
