tele-TASK is a university research project broadly speaking in the e-learning area with an application to lecture recording, post-processing and distribution. Some of the research topics derive from the fields e-learning and tele-teaching, semantic web, video analysis, speech recognition, collaborative learning, social networking, web technologies, recommendation systems, statistics, video codecs and conversion, and many more. The project was founded by Christoph Meinel and his research group at the University of Trier. When he accepted the chair for Internet Technologies and Systems at Hasso Plattner Institute at the University of Potsdam/Germany, the tele-TASK project also moved to HPI.
