Lecture recording provides learning material for local and distance education. The TeleTeachingTool uses the most flexible screen recording technique to capture virtually any material displayed during a presentation. With its built-in annotation system teachers can add freehand notes and emphasize important parts. Unlike other screen recorders, our implementation offers slide-based navigation, full text search and annotated scripts, which is obtained by automated post-production. This paper presents how to achieve live access to any slide with corresponding annotations created earlier during the presentation, although annotations are not associated with slides. For this the post-processing algorithms must be adapted to work on the fly while the presentation is still in progress and an interlinkage between slides and annotations must be achieved.
