  • Bijective BWT (6 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    So many of today’s files are already compressed (using old, outdated algorithms) that newer algorithms don’t even get a chance to touch them.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.

    Its old news that China has developed their own Advanced Video Standard to avoid high licensing fees. English translation of the standard is now available, along with the IPR policy. Finally something technical that you can get your hands on to feed your appetite.

Video Compression Claims

Posted by Mark Nelson on 18th November 2005 | Permanent Link

I got an email from the MWW Group yesterday. MWW is a flack outfit that is promoting new video compression technology from their client, Scotland-based firm Essential Viewing . Samantha makes some pretty exciting claims for their new product, GlobalVision gv300:

In response to the need for a digital video encoder that functions at extremely low bandwidths via satellite networks, Scotland-based firm Essential Viewing has developed GlobalVision gv300. This innovative software application allows high-quality video to be transmitted from networks with bandwidths less than 200 kbps. Prior to the release of Essential Viewing’s encoders, the availability of this was virtually nonexistent. The gv300’s unparalleled scalability allows effective streaming options at bandwidths as low as 9.6 Kbps.

Well, that sounds pretty exciting. Video at 9600 bps? So I go the company web site and download their fact sheet. Even more interesting claims:

The gv300 digital video encoder has a number of key differences
from standard MPEG-4 and H.263 systems which make it uniquely
qualified for military intelligence, law enforcement, security and
industrial applications.

I managed to find a little more info on the web site, but nothing substantial:

The technology at the core of the Essential Viewing products is aimed at the effective coding, transmission and viewing of real-time video over low bandwidth, wide area networks. Based on the flexible and dynamic Essential Video codec, the system utilises a number of video compression techniques using our BestFirst® algorithm to define the most efficient method to achieve optimal visual results over the available bandwidth.

Given the lack of benchmarks, demos, or specifications, I’d have to say the first guess is that there’s not much behind the curtain.

    Extraordinary claims require extraordinary press releases.

    The most ignominious case, of course, is Maui X-Stream.
