TIB AV-Portal: A reliable infrastructure for scientific audiovisual media

Abstract

With the AV Portal 1 , the German National Library of Science and Technology (TIB) 2 in collaboration with the Hasso Plattner Institute (HPI)3 has developed a user-oriented platform for scientific films. This portal offers free access to high-quality computer visualisations, simulations, experiments and interviews as well as recordings of lectures and conferences from the fields of science and technology. The automatic video analysis of the TIB AV Portal includes not only structural analysis (scene recognition), but also text, audio and image analysis. Automatic indexing by the AV Portal describes videos at the segment level, enabling pinpoint searches to be made within videos. Films are allocated a Digital Object Identifier (DOI), which means they can be referenced clearly. Individual film segments are allocated a Media Fragment Identifier (MFID), which enables the video to be referenced down to the second and cited. The creator of the audiovisual media segment can choose between an Open Access licence and a declaration of consent, enabling them to decide how they wish to permit TIB to utilise the material. TIB recommends the “CC-Namensnennung – Deutschland 3.0” licence, which ensures that the creator is acknowledged and permits the comprehensive use of audiovisual media in research and teaching.
