Media Matters LLC Gives First Public Demonstration
of Real-Time Audio-Video Lossless Compressed Encoding
Card at National Library of Medicine
Lossless Digital Video Preservation
based on Motion JPEG2000 Wavelet Algorithms
Bethesda, Maryland – August 1, 2005
– Justin Dávila, System Architect
and Technology Consultant for Media Matters LLC,
gave the company’s first public demonstration
of its new Motion JPEG2000 lossless encoding card
at the “Getting to Disk-based Lossless Digital
Video Preservation” symposium held at the
National Library of Medicine. The real-time audio-video
encoding hardware provides mathematically lossless
compression using wavelet-based algorithms, preserving
video content in a Motion JPEG2000 digital file
that is about one-third the size of uncompressed
video with no loss of information, plus synchronized
lossless audio in standard BWF format.
The NLM symposium gathered many of the nation’s
leading authorities from government, academia
and industry in the field of digital preservation
to examine technical standards and best practices
for long-term video archiving needs that are based
on the mathematically lossless compression of
frame images. The topics of discussion included
the various lossless file formats, codecs, and
encoding parameters along with issues related
to associated metadata and rights management.
Mr. Dávila explained that development of
the Motion JPEG2000 encoding card derived from
research Media Matters did for the Dance Heritage
Coalition on digital video preservation file formats,
which resulted in the Digital Video Reformatting
Project report (www.danceheritage.org).
The report concluded that requirements for quality,
usability, and preservation were all uniquely
met by Motion JPEG2000. Media Matters immediately
began creating a real-time hardware solution to
use in SAMMA, the automated, robotic videotape
migration system that Media Matters has developed.
Mr. Dávila’s presentation consisted
of real-time hardware audio and video encoding,
file playback on a computer, and real-time hardware
audio and video playback. He played a clip from
the DHC research project into the encoder, creating
synchronized audio and video files. He then played
back the standards-compliant BWF audio file of
the clip through the computer. Finally, he played
the contents of the encoded files through the
card, which played video through SDI output to
the projector and audio to a speaker.
