By Ian Gilmour of Media Matters. From the abstract: Motion-JPEG2000 lossless data reduction is implemented as a key technology for reducing file size in storage and for reducing data rates in networked file transfer.

An August 1, 2005 invitational meeting gathered about fifty archivists and technologists involved in the long term preservation of videos and films. The meeting, "Getting to Disk-based Lossless Digital Video Compression", was hosted by the U.S. National Library of Medicine, itself much involved in moving image preservation.

Participants considered the potential of lossless, on-disk video storage in light of the "twilight of tape" as a cost-effective storage media. Other speakers reviewed current video metadata standards, and recent work in automatic extraction of metadata from video. The meeting included the first public demonstration of real-time, full-screen, mathematically-lossless video compression and decompression based on the Motion JPEG 2000 (MJ2) standard.

Heard during the Google and Libraries: What’s in Store for Google Print and Google Scholar presentation at ALA: participating libraries can receive either G4 TIFF or JPEG 2000 image files for the scanned books. No word yet as to whether they are JP2s, JPXs, or JPMs...

On 3 November 2005, a panel at the annual meeting of the Museum Computer Network (MCN) will address some of the ways in which museums are using JPEG 2000. One speaker will offer a general introduction to JPEG 2000; two subsequent presenters will discuss its current state as a delivery format and its relationship to digital preservation in their institutions. The conference will take place in Boston; more information regarding this and other MCN panels may be found on the MCN2005 sessions web page.
