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.

As a follow-on to last summer's gathering of video archivists and
technologists here at the National Library of Medicine, I have been
considering ways to encourage lossless video encoding for preservation,
with a particular interest in JPEG 2000 frame encodings.

Towards that end, and following a suggestion by Ron Murray at the
Library of Congress about MPEG-A as an attractive vehicle for
cross-cutting standards, I've drafted a "strawman" set of documents for
the community's consideration, which may be found at

"Declaring an end to dictated formats and closed solutions that cause workflow inefficiencies and frustrate broadcasters and videographers, Thomson today announced the Infinity™ Series, a new line of next-generation acquisition, recording and storage devices that give broadcasters and videographers the power of choice — in recording media, formats, compression codecs,
and connectivity."

...

"As an additional choice of compression, the next-generation JPEG2000 codec is also included. JPEG 2000 offers special advantages over other compression codes: it offers higher-quality compression with better efficiency, delivers superb images without blocking artifacts at low bit rates, and, with its unique scalability, allows broadcasters ultimate flexibility by enabling them to encode a master file and then decode different resolutions as necessary."

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.

"Pulse~LINK, Inc., developer of CWave(TM) Ultra Wideband (UWB) communications, and Analog Devices, Inc., a global leader in high-performance semiconductors for signal processing applications, have joined forces to demonstrate the industry's first wireless transmission of real-time High Definition video. The joint demonstration, featuring a side-by-side comparison of MPEG and JPEG2000 across Pulse-LINK's UWB wireless link, will take place at the DisplaySearch HDTV Conference, August 23-24, 2005, in Beverly Hills, CA.
