MXF files that wrap JPEG 2000 codestreams (bitstreams not wrapped in the file format described here) are the preservation masters in the video reformatting work carried out by the Library's Motion Picture, Broadcasting, and Recorded Sound Division at the Packard Campus. Meanwhile, the Library and the National Endowment for the Humanities have specified JP2_J2K_C_NDNP for use as lossy-compressed service images in the National Digital Newspaper Program, launched during 2004. JP2_FF files with lossy compression are being used for the service images of maps in American Memory, where they have replaced the MrSID files used formerly to provide zoom capabilities for large images.

See Notes below for additional information. The extended capabilities of JP2 grow out of its object-based design and its ability to wrap object types beyond JPEG 2000 core bitstreams, e.g., auxiliary opacity/transparency channels, color profile information, and other metadata. Its role (although not its extended capabilities) has been compared to that played by JFIF for JPG_DCT (JPEG encoding). Wrapper developed by the Joint Photographic Experts Group (JPEG) for still images using JPEG 2000 core encoding.
