Web Conference Systems

Overview of internet-based videos and online conference platforms

For some time now, solutions for online communication in research, teaching and administration have been available at the university. The current situation of the Corona pandemic has created a new, unprecedented need for the use of these systems in all three areas. In response, the resources and server capacities in the data center have been significantly increased in the summer semester. In reaction, a new scaling cluster with the open source software "BigBlueButton" was set up and docked to the learning platform ILIAS. For the external solution ZOOM, licenses for teachers were procured to cover the demand for solutions for large groups (lectures and seminars with more than 50 participants).

In the winter semester, it is recommended to exclusively use BigBlueButton or Zoom, depending on the application scenario in teaching. In addition, "Panopto" is available for video recordings and webcasting without participant interaction.
