This article in the Washington Post reports that On2 is being purchased by Google for $106 million in stock.
On2 has a really excellent video codec with some advantages over industry standards from Microsoft and the MPEG. But the relatively small price for a well-established and sporadically profitable company points out the difficulty faced when trying to sell video compression not backed by industry standards groups.
One often used metric on a buyout is the cash value per employee. In this case, it’s roughly $1.75M for each On2 employee. Just to contrast, earlier this year my employer, Cisco Systems Inc., acquired Pure Digital, makers of the Flip video recorder. In that case, the payout per employee was roughly $5.8M per head.
Probably not apples-to-apples, but something to think about.

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.

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.

So many of today’s files are already compressed (using old, outdated algorithms) that newer algorithms don’t even get a chance to touch them.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

If you are in any way interested in data compression, DCC is a place where you really want to be. Where else can you expect to meet so many people who can all get so excited about saving 5 more bytes. Submissions for DCC 2008 are due by November 12.
