Local use Explanation of format description terms

LC experience or existing holdings Video reformatting in the Library's Motion Picture, Broadcasting, and Recorded Sound Division employs individual frame images with lossless compression; these are, however, codestreams and not in the JPEG 2000 wrapper. At this writing (January 2012), there are plans to study the applicability of both lossless and lossy JPEG 2000 as master images (in the JPEG 2000 wrapper) for still-image-based reformatting projects.
LC preference None established.
