Guides and contact informations


BigBlueButton (BBB) is an open-source web conferencing system that is operated in a data protection-compliant manner together with the Philpps-Universität-Marburg. The following scenarios can be implemented with BBB:

  • Lectures: up to a maximum of 250 participants (audio/chat), video stream/webcam for lecturers and moderators.
  • Seminars/exercises/projects: up to a maximum of 100 participants (audio/chat/video/webcam)

The BigBlueButton deployment is part of an evaluation process. This means, among other things, that settings and functionality may change due to operational safety.



The application offers many important functions for online teaching, e.g.:

  • Share audio/video
  • Share screen
  • Share presentation
  • Chat with all or individual participants
  • Conduct polls or surveys
  • Whiteboard for collaborative content development
  • Shared notes for the development of content or for minutes
  • Break-out rooms: use additional rooms for group work in parallel for a defined period of time
  • Telephone dial-in (e.g. as fallback in case of audio problems) possible
  • Please note that no recording function is available for the time being.



BigBlueButton works in the browser, there is (currently) no official app. As a browser, we recommend Google Chrome (or Chromium / the new Microsoft Edge Chromium) or Mozilla Firefox on all platforms (Windows, MacOS, Linux). On iPhones and iPads, Safari must be used, but splitting the screen and activating the virtual background are not possible there, just as on Android mobile devices. Please note that there is currently no recording function available. Further information on the system requirements can be found in the FAQ.


Creating conference rooms

Conference rooms can be created

  • via Stud.IP (as a teacher in the course -> More -> Activate "Meetings"),
  • via ILIAS or k-MED (as a teacher in the course -> New object -> Virtual meeting room) or
  • via Webconf (to generate an invitation link that can be sent by e-mail, login with the user name and password of JLU).
