Abstract
This presentation gives a deep view into the development of a file system, especially designed for scalable media files including JPEG 2000 and H.264 SVC. By applying specially developed techniques, including the Substitution Strategy, a real-time capable file-system can be built, even if the mass storage, or the interface to it, is too slow to deliver the data in the desired time. Rather than skipping whole files, new caching strategies will be shown that again, take advantage of the file-inherent scalability. The presented system also comprises an advanced user-rights-management that allows for granting access-rights to certain parts of a scalable file, rather than granting rights to whole files. Users will therefore get a different version of an image or video, dependent on their current access-rights.
