During the digitalization of film footage and the digital production of cinematic movies enormous amounts of data are generated, which can easily reach several terabyte. In order to master this amount of data and realize a high-quality digital preservation, a two-step model is intended in the architecture. Digital available material is being created in two different quality levels and stored.
The highest quality level is the so called “Master Archive Package”. In this format the digitally available pictures can be saved in a resolution, which displays the best representation for the analog output format. The amount of data is reduced with a lossless compression method, although it is usually still too high to work directly with the data. Nevertheless, this format can be used to perform a digital restoration for example.
In order to enable an easier access, the so called „Intermediate Archive Package“ is generated via an automatic conversion process from the „Master Archive Package“. There the footage is transferred to a possibly lower, but firmer resolution level. To bring the data into a manageable order of magnitude, the material is compressed with losses.
From the „Intermediate Access Package“ metadata can be extracted automatically and transferred into a database for online-access. Users get the opportunity to search material, based on the metadata. For a preview the media data in the package can directly be accessed. If the user has found the desired movie he can order the whole movie or just cutouts in the best suited format for his use. An automatic conversion process is then going to generate a „Dissemination Package“ with the desired material from the „Intermediate Access Package“ and make the files available for download or streaming. Different user groups from cinema to TV channels, for example in need of cutouts for reports, as well as private users can be served from the same database.
