ADMIRA is a service offering which provides media essence 4 management. It
can complement the infrastructure to close the gap between normal IT based
tools (like TSM) and digital media tools (like a content management application).
ADMIRA is a middleware layer that helps overcome typical problems of
managing large video and audio files on IT storage infrastructures. Since large
video and audio files are sometimes accompanied by descriptive metadata, low
resolution versions and key frames, ADMIRA checks the consistency between all
these files and performs necessary video and audio format transcodings and
analysis. ADMIRA performs all media processing tasks as transactions so that
rollbacks and cleanups will be performed if an error occurs. Depending on the
frequency a file needs to be used, different storage platforms (online, near online,
near line, and offline) and sometimes all together are all used.
4 Essence - a video file, information on a videotape or a graphics image.
