Perspectives for lecture videos

This article presents an architecture for automated multi-perspective lecture recordings. The implementation switches between several video streams showing different perspectives in order to make the recording more vivid and to reduce the tunnel vision effect of single-perspective recordings. Automatic switching can be based on time intervals or, at a later stage of development, via simple recording rules.

Bridging media breaks in presence presentations

The integration and fusion of different media input streams into one unique presentation stream is very important for maintaining the live aspect in recordings. The described core component of the Digital Lecture Hall [2] handles these requirements. It also supports annotating any content, as well as database storage for further processing of all collected materials.
