Audiovisual Technology Group

The Audiovisual Technology Group deals with the function, application and perception of audio and video equipment and systems. An essential focus of the research is the relationship between the technical characteristics of a system and of human perception as well as the user experience ("quality of experience").

Aspects of the entire chain will be considered by production, recording, transmission, reproduction, perception and experience of voice, audio and video signals. Current research relate to the possibilities offered by converged, IP-based networks for new multimedia services, as well as immersive audiovisual technologies as UHD/4k and 360° video or sound field synthesis based spatial audio.
