Everyone who is interensted in can participate in Meinel's live and online lectures. The lectures will be held live on the Internet under Prof. Meinel is a Computer Science Professor (C4) in Trier, Germany's oldest town.

As Prof. Christoph Meinel presents the lectures in his lecture room using his laptop and acting in front of a web cam, it is already afternoon in China and still night in the US. "Anyone who missed the lecture can go to and download a recorded session at a later convenient time" says the scientist. Tele-task provides a drastically simplified access technology developed in Trier, which simply needs an ISDN or DSL connection and a "Real Player" to work. In this way anyone interested can without any problems and comfortably connect live to the Trier University lectures on Internet security using his home or office computer or get them downloaded later.

"Tele-task stands for Teleteaching Anywhere Solution Kit" says Prof. Christoph Meinel. Not only flicker-free picture and clean tone of the speaker can be transmitted, but also synchronised, large-sized video content of the presentation as well as additional materials, graphics and computer animation. The transmission speed ranges from 38 kBit/s to 300 kBit/s (standard) up to between 800 and 900 kBit/s - the quality standard required for DVD. If using ISDN speed, Tele-Task can guarantee a picture format of 850 (horizontal) x 500 (vertical) - more than any current transmission technology can offer.
