Note on the use of video conferencing systems in teaching from the summer semester 2022 onwards

In the summer semester of 2022, courses at TU Darmstadt will once again be offered with full face-to-face teaching ans studying. Online offerings can be a useful addition to this, but should not be absolutely necessary to successfully attend a course.

Nevertheless, the TU Darmstadt has decided not only to extend the licences for Zoom, but also to introduce another system, BigBlueButton (BBB).

Zoom is not only the tool that many users are more familiar with, but also has some technical advantages. Especially with large events (well over 100 participants) or the sound quality, the differences are clear. However, Zoom is not without problems in terms of data protection, as the legal standards in the EU and the USA are not well compatible. Using Zoom should therefore be made optinal for all participants.

BBB, on the other hand, is unproblematic from a data protection point of view. The environment is operated by the Darmstadt University of Applied Sciences (h_da) on its own servers, but is technically less powerful in some places.

Teachers can decide for themselves which system to use.

Because the summer semester is designed as an attendance semester, a video conferencing system can only be used if all participants agree to it.

Web conference systems


With Zoom you can organise web conferences and online events with up to 300 participants. The tool offers screen sharing functionalities and a chat, etc. Due to its excellent usability and high availability also for higher numbers of participants, the cloud service is also well suited for online courses.

The Zoom campus licence is available for all employees and students of TU Darmstadt.

BigBlueButton (BBB) is an open-source web conferencing tool for conducting online meetings, which is offered in a data-protection-compliant manner in cooperation with the Darmstadt University of Applied Sciences (h_da). The tool offers many important functions to support online offerings in teaching and can be used immediately in courses.

All information about BBB


Via DFNconf – the conference service in the German Research Network (DFN) – you can organise video and audio conferences on the web or on mobile devices free of charge. Information can be shared during the meeting via video or screen sharing.

Employees can participate in conferences and set them up whereas students can participate only.

Jabber: The Unified Communication Client at TU Darmstadt

Using the Jabber Client, TU employees who have a Cisco device with personal telephone number can set up video conferences, share screen contents and even exchange files with just a few clicks, without leaving the application. Learn more

When more than two people participate in the video call, the Cisco Meeting Server becomes active. Independent of the Jabber application, the Cisco Meeting Server can also be accessed via a web interface. This is especially useful if you plan to invite non-TU members to your meeting. The conference platform is suitable for meetings with up to 30 people.

The servers for UC telephony and meetings are located at the TU Darmstadt and are also administered there. The conference platform thus complies with the requirements of the DSGVO. Quick guide
