  • 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 (116 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    So many of today’s files are already compressed (using old, outdated algorithms) that newer algorithms don’t even get a chance to touch them.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.

A monthly roundup of all news and happenings reported at The Data Compression News Blog. More information about this newsletter at http://www.c10n.info/newsletter/

I have added at www.c10n.info a section featuring the latest data compression patents granted or filed. But unfortunately its not working as good as I expected. It should be getting updated every week, but its not happening yet. I have explored further on how the research papers section can be built, you will be seeing it soon. Lets see how it goes.

I have reduced the frequency with which I blog, most of the news can be tracked at Industry News page http://www.c10n.info/newsbot/ and not every news can be commented upon.

And I am not sure if all that news should be included in this monthly news letter. As you are the audience, let me know what you will prefer and we will go that way.

As usual, any other tips or advice you offer will help a lot in making c10n.info a better site for all of us :-)

XML-WRT is a high-performance XML compressor by Przemyslaw Skibinski. It transforms XML to a more compressible form and uses zlib (default), LZMA, PPMVC, or FastPAQ8 as back-end compressor. It is similar to XMill, but has many improvements like semi-dynamic dictionary.

LAW.COM: The fierce court battle between digital video recorder pioneer TiVo Inc. and cable television giant EchoStar Communications Corp. has been shunted to the U.S. Patent and Trademark Office, which may signal the increasing role of that office. If the trend catches on, it could delay outcomes of patent disputes by years.
