  • Bijective BWT (7 Comments)

    David Scott has written a bijective BWT transform, which brings all the advantages of bijectiveness to BWT based compressors. Among other things, making BWT more suitable for compression-before-encryption and also give (slightly) better compression.

  • Asymmetric Binary System (113 Comments)

    Jarek Duda’s “Asymmetric Binary System” promises to be an alternate to arithmetic coding, having all the advantages, but being much simpler. Matt has coded a PAQ based compressor using ABS for back-end encoding. Update: Andrew Polar has written an alternate implementation of ABS.

  • Precomp: More Compression for your Compressed Files (3 Comments)

    So many of today’s files are already compressed (using old, outdated algorithms) that newer algorithms don’t even get a chance to touch them. Christian Schneider’s Precomp comes to rescue by undoing the harm.

Selling Out on Standards

Posted by Sachin Garg on 21st June 2005 | Permanent Link

ComputerWorld has this excellent article on the standards and how they are no longer what they used to be.

The increasing trend towards patenting and contributing IP to standards only to later extort money from all users is very disturbing. Author Robert L. Mitchell asserts that the good old days where companies cooperated and contributed to build successful standards like ethernet are just some golden memories.

And unfortunatly, data-compression has been no exception to this. (Forgent’s case with Jpeg, DRM patent issues with ContentGaurd etc…)
