MPEG and other DCTbased codecs have been designed to optimize the compression efficiency to deliver video to viewers via a pipe with limited bandwidth. JPEG 2000 is different from other video codecs. Library of Congress, the French Institut National de l’Audiovisuel (INA) and several Hollywood studios have selected the codec for the long-term preservation of a century of audio-visual contents. The ongoing standardization process of the Interoperable Master Format (IMF) by SMPTE based on JPEG 2000 profiles brings the adoption full-circle.

In parallel, these broadcast profiles have also filled the industrywide need for compression standards to archive and create mezzanine formats, allowing transcoding to a variety of media distribution channels. Standardized broadcast profiles were adopted in 2010 to match current industry needs (JPEG 2000 Part 1 Amendment 3 - Profiles for Broadcast Application - ISO/IEC 15444-1:2004/Amd3), ensuring this wavelet-based codec’s benchmark position in contribution. This is the story behind the rapid adoption of JPEG 2000 compression in the contribution chain. They also have a vested interest in a common high-end format to archive, preserve and monetize the avalanche of video footage generated globally. Today’s broadcasters are looking for the highest image quality, flexible delivery formats, interoperability and standardized profiles for interactive video transport and workflows.
