Development of a Digital Lectern for Teleteaching

Increased capacity of the network will also provide the possibility to transmit pictures and sound. This is of particular interest if speeches, presentations or lectures have to be recorded or transmitted in order to make them accessible at a different location or to a larger auditorium. Very often additional information has to be transmitted simultaneously as for example the visualization of overhead slides or PowerPoint presentations with additional annotations. Up to now this has not been possible or only with a large number of staff and financial expenditure and thus is refused in many cases. This paper describes the construction and the functionality of a digital lectern named “Speaker’s Corner” that solves the problems described above and also allows the use of conventional media.
