Breaking the rules

The laws of physics say you can't squeeze data this much

“BE CAREFUL what you wish for,” runs the adage, “because you might just get
it.” Well, publicity to attract finance for a revolutionary data squashing
“compression” technique was the wish of ZeoSync when it posted a press release
on its website—and publicity is what it got. But much of the comment
that’s been buzzing round the Internet has been, frankly, sceptical. Many expert
observers say they don’t see how the compression system ZeoSync claims to have
invented can possibly work. But if it does, it will boost Internet speeds and
computer memory capacities a hundredfold.

To get to the bottom of the firm’s claims—which fly in the face of
accepted communications theory—èƵ secured an exclusive
interview with ZeoSync chief executive Peter St George. Speaking from the
high-tech firm’s Florida offices, St George reiterated the claim that his
technology can compress “practically random” sequences of audio and video data
by a massive 100 to 1 “while preserving perfect quality of information” after it
is decompressed.

St George says he has so far succeeded in processing only “a few hundred
bits” of data at a time using his idea. He filed one patent 12 months ago and
expects to file another 50 this year.

One firm eagerly awaiting sight of these new patents is the British firm
Meridian, which developed a compression routine called Meridian Lossless Packing
(MLP), which is already patented and in use worldwide by anyone with a DVD
player. MLP discards any data representing silences or unwanted noise. Even so,
it cannot compress files by more than 5:1—and that’s on nonrandom data.
ZeoSync claims its 100:1 compressor works on “practically random” data.

But St George says he has never heard of MLP, despite having spent a “dozen
years” developing the new system.

MLP was co-developed by Bob Stuart of Huntingdon-based hi-fi company
Meridian. Stuart is sceptical of ZeoSync’s claims. “The giveaway is [ZeoSync’s]
claim to compressing ‘practically random’ and ‘very small’ bit streams. Unless
the laws of physics have changed overnight, if a bit stream is truly random it
is unpredictable and cannot be compressed,” Stuart says.

In August 1998, the DVD Forum, which sets standards for the DVD format,
adopted MLP as its compression system for “super hi-fi” sound. It lets Dolby
Labs in San Francisco license MLP to DVD manufacturers. Having examined
ZeoSync’s sketchy technical information (www.zeosync.com/flash/pressrelease.htm),
a Dolby spokesman says it is “hard to make any real sense
of the information provided”. It hopes ZeoSync’s patent applications will be
enlightening.

Acknowledging mounting scepticism, St George says he is planning “an Internet
demonstration” for “hundreds of thousands of computer scientists”. Stuart says
stringent tests will be necessary, but St George says he is confident his system
will pass the tests. He reminded èƵ that people once thought
that humans would never fly, and that the Earth was both flat and at the centre
of the Universe.
