Abstract: We discuss a system to broadcast the live experience of university lectures and to
archive it for further asynchronous use. At the time of lecture the broadcast is bi-directional, to
guarantee interactions between local and remote classes: both rooms display the teacher's
educational material while the video of the teacher is projected in the remote class and the remote
class in the teacher's room. Questions can be risen by students in both settings. The project
requires minimum overhead on a teacher and no post-production. We give teachers the freedom
to use different sources of information to deliver their lectures (slides, video, audio, a white-board
for quick sketches, applications running on a desktop). All these events are captured and
compressed into two video streams that are accessed through an interface generated by SMIL.
The lectures archive is integrated with other communication tools, such as e-mail, forum or
collaborative web.
