Abstract

This paper describes a new way of creating multimedia documents combining recorded lectures and students' personal notes. Students use multimedia recordings of live presentations for revision and exam preparation. Based on the "Authoring on the Fly" concept we have developed a new system for multi-layer recording, where prepared materials, annotations made by the lecturer, and students' personal notes are captured during a live lecture. We describe the shift from the stand-alone lecture recording system to shared session recording and discuss the main issues which need to be tackled in the recording and the replay scenarios. We also point out the differences to other existing concepts. Finally we give a short vision of how the system could be used as a collaborative tele-recording tool in the future.
