RFC 2190 describes the Internet standard for encapsulating H.263 in an RTP packet stream.

The term bijective as used by Scott means that for any given given file X you are guarantted that A( B( X ) ) == B( A( X ) ) == X, where A and B are a pair of bijectively matched programs. In this particular case, A and B are a compressor and decompressor that use arithmetic coding. Includes C++ source.

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.

The submitter said: SBC is Burrows Wheeler Transform based file archiver. It’s one of the fastest BWT implementations with high compression ratio. SBC also introduces a high security options with a number of strong encryption algorithms.
SBC appears to be shareware. Comment from a DCL user: Cool archiver; the author has made great effors to make it really fast and also added a lot of heuristics to behave well on multimedia data.

The home page describes Kakadu thus: A comprehensive, heavily optimized, fully compliant software toolkit for JPEG2000 developers
.

DataCompression.info user Tim A. gushed: A very fast implementation with a small memory footprint compared to Jasper and even other commercial implementations. Also handles large files better than all others I have tried. Very well done with motion JPEG2000, a viewer and a JPIP server to boot (and those are just the sample applications!). John J. added The best of any JPEG2000 compressors for lossless compression. Higher compression rates, and faster compression than Aware and Algo Vison Luratech.

Lossy data compression which can reduce input files to 0% of their size. Hint: product was released April 1, 2000.
DCL reader Tim A. marvels: Wow! it’s even faster than tarring to /dev/null!

This web page shows a set of images that the author uses to demonstrate the performance of the Eri compressor. The claim is that Eri32 does better on these 24 bit color images than any other lossless compressor.

EE Times reports on a development which would allow HDTV and NTSC to coexist on the same frequencies. It’s a hack, and it takes a lot of compression, but it keeps existing set owners online after cutover.

Andrey Fomin has posted a long Russian paper in word format on his web site. You’ll need a Microsoft Passport (free) to get here, but it’s worth the trip if you can read it.
Andrey has this to say about his paper/book:
A survey of different basic Data Compression techniques. Uses some mathematical and statistical materials, but doesn’t require a
special scientific degree. Though written in Russian, this book contains VERY useful References, Examples and Source Codes!
