HoloDynamic Compression: Mapping Miracles into the Machine

A great example of an incredible compression claim. There’s just a teeny tiny bit good thinking in here, and a huge amount of tangential speculation attempting to walk upright on two legs. Read it and just be glad the author doesn’t seem to be raising funds.

Chaotic Compression?

Kevin Short at the University of New Hampshire has created a company called Chaoticom that is raising money to develop his new idea called Chaotic Compression Technology. Until we see some papers, algorithms, or products this is going to have to be categorized as an Incredible Claim.

MINC Lossless Digital Data Compression System

Back in 1998 I heard from a poor soul who was being encouraged to put some money into the Premier America, makers of the MINC Compression System. Seeing that MINC promised an iterative compression system that guaranteed any ratio you cared to dial in, I encouraged him to run, not walk, away from this opportunity. This led to an email conversation with someone from the company, assuring me that they would have a real product on the market quite soon now.

I haven’t heard a peep out of Premier America since then, so hopefully they have stopped raising funds for their unlikely system. Fortunately, a good soul named Chez DuLac has preserved MINC’s manifesto on his web site, along with his reasoned rebuttal.

Florida Compression Scheme Nets Millions

This isn’t a new story, but the Florida Times-Union of Jacksonville gives a lot of detail in this treatment. A fellow named Madison Priest seems to have pulled in millions with his promises of hardware that can push high quality movies over conventional phone lines. Lots of interesting details, including the famous coax line hidden in the power cord! The second part of this story can be found

Pixelon Bites the Dust

Pixelon shows what happens when technology gets mixed up with big bucks and shady characters. The Industry Standard ran a great story on it, but as they have gone belly up
this link may not work any more. So this CNet news article will have to do.

Reader Tim A. points out that they also claim that ‘No longer is it necessary to produce complex waveforms by summing sinusoidal signals at varying frequencies’, yet later call their process an ‘additive reconstruction process’. Sounds much like the same process to me, just with different starting waveforms..

Teddy Turner Mixed Up In Compression Lawsuit

Teddy Turner, son of CNN mogul Ted Turner, was apparently named in a lawsuit in 1999 over an alleged misrepresentation of compression claims. A Florida company named Vision Tek claimed it could pump video over normal phone lines at high speeds, but was not able to satisy its investors, leading to a court case.

The $5000 Compression Challenge

Patrick Craig has an interesting tale to tell. Without being a data compression expert, he managed to beat the $5000 compression challenge. You won’t see him taking an ocean cruise with his winnings, though. DCL reader commented: The challenge was obviously met.

Magic Function Theory

This is a recurring theme in comp.compression, which I call “The Magic Function Theory.” It sounds like a good idea, but analysis shows that it won’t work.

Mathematical Combinations and Compression

The comp.compression newsgroup regularly sees posts from folks with incredible compression claims. This one, started by Itai Bar-Haim, is remarkable not so much for its claims, but rather for the incredible length of the thread it spawned. All Atai said was that mathematical combinations have nothing to do with compression. So there.
