Audiovisual Technology Group

The Audiovisual Technology Group (AVT) deals with the function, application and perception of audio and video equipment and systems. An essential focus of the research is on the relationship between the technical characteristics of audio, video and audiovisual systems and human perception and experience (“Quality of Experience”, QoE).

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