Audio-visual Systems
Be it the media archive of a TV station or the personal photo collection on your computer – large assortments of media pose one challenge: pictures, videos or audio files can only be found on by means of the given filename or manually assigned keywords. The researchers in the field of Semantic Audio-Visual Systems carry out the development of technologies and methods for automated content based description of video signals to facilitate the recognition, search and processing of multimedia data.

Media Distribution and Security

More and more business transactions are processed via the Internet. Digital content is distributed online, transactions are managed and sensitive information are exchanged. The development and realization of business models for secure, user-friendly and technically efficient distribution of virtual goods – e.g. MP3-files – is the emphasis in the business area "Media Distribution and Security".

Audio Coding for Special Applications

Since the early stage of digital audio technology, researchers strive to compress the data ratio of multi-media based content. High memory requirements of uncompressed data, limited transfer rates in digital broadcast and the transmission of audio signals via Internet required a radical "slimming cure" of the signals. In collaboration with the Fraunhofer Institute for Integrated Circuits IIS in Erlangen, the Fraunhofer IDMT works on both perceptual coding and lossless coding in order to reach an optimum of compression and audio quality.

Data Representation and Interfaces

Recent technology-based learning and working environments are frequently engineered in a manner that provides only a relatively static experience. This often appears as a barrier to effectively exchange data and metadata, to sustainably manage archiving in repositories, and digital preservation as well as to accomplish efficient networking. Today, those user-friendly networked learning and working environments are essential that allow for managing individual concepts, and for structuring and delivery of digital content. Additionally, these environments need to reflect on the existent and the necessary competencies of the users, and also on the individual preferences in an organizational framework.
