Scenario B: Lecture as live stream from the lecture hall

Attention: The lecture halls have not yet been adapted as planned due to delivery delays. We will inform you about the current status of the individual lecture halls on this page. Please refer to the shown table to see what is already available in which lecture hall.

In the lecture halls, the media technology will be supplemented at short notice so that a livestream with the help of zoom is possible from there. To use it you need a zoom license as a teacher and you have to bring your own laptop. A webcam and the use of the Visualizer are provided in the lecture halls. In many lecture halls, the existing microphone can also be used in Zoom. In some, smaller lecture halls this is unfortunately not possible. In these rooms you have to connect your own microphone to your laptop. Wherever possible, Internet access is provided by cable via LTA access. Where this is not possible, restrictions in the reliability of the Internet connection must be accepted and the KIT-WLAN must be used.

If you want to use this scenario, please pay attention to the generalinstructions for implementation. The described procedure represents the simplest possible implementation available in the area. Of course, more complex variants are possible on your own responsibility. Please always remember not to change the wiring in the lecture hall so that other lecturers can work reliably after you.

Why no blackboard picture?

The visualizer is used instead of the blackboard. This means that you can write on paper and show it in Zoom on the beamer and in the livestream. A blackboard picture would have to be filmed manually with a camera. No staff can be provided centrally for this. Furthermore, the result would often be difficult to read with the resolution of the online media and only a section of the panel image would still be visible in the recording.

Your own laptop as media control!

Unlike before, the control is primarily no longer done with the media control of the lecture hall, but on your laptop. There you create the desired presentation from the visualizer image, your own content such as a presentation and elements from the return channel of Zoom and Chat. You output this presentation once to the beamer in the lecture hall and in Zoom as a stream. To make this possible, the visualizer signal, the webcam and the microphone are made available to you via USB cable. The output to the beamer is done via HDMI cable. Switching between different contents in the event is then done on your end device in Zoom during the event.

Which contents are possible?

In principle, you can use anything that can be displayed on your end device. This could be PowerPoint presentations or other screen content, for example. The image of the visualizer is made available to you via USB as a second webcam. You can select it as a second webcam in Zoom in the screen sharing function and thus show it both in the live stream and also on the beamer in the hall. At the same time you can show yourself in the stream with the help of the webcam.

Can the lecture/seminar also be recorded?

In principle, this is technically possible without further hurdles. However, the requirements of data protection must be observed. Students may not be recorded. This would require written consent and administration for the later, targeted processing of individual deletion requests. This also applies to the spoken word in case of questions. You can either split the lecture into a recorded lecture part and an unrecorded discussion part, or pause the recording for the discussion parts in between. In this case, you first pause, then let the question be asked, start the recording again, repeat the question for the recording, and then answer it.

Lecture halls without a suitable microphone

In some lecture halls the existing microphone cannot be used within Zoom for technical reasons. In order for online students to be able to hear you, you need an additional, suitable wireless microphone of your own. As far as possible, you should avoid using the microphone provided in the lecture hall if it is not necessarily needed for students present in the room. Further information on this can be found in the equipment notes.

Instructions for using zoom in the lecture hall (coming soon)

Notes/Reminder on using Zoom

Microphone icon (bottom left): One to several USB devices appear here. Select them in order and check for which one you will see a green color in the microphone icon when you tap on the microphone when it is unmuted.

Also select the HDMI output of your laptop as speaker, so that contributions from students who are online can be heard in the hall.

Camera icon (bottom left): Select the webcam built into your laptop or the additional USB webcam that you want to show. The camera device for the visualizer also appears here, but is not selected here.

Share screen (bottom middle): Here you can share or switch between different contents for display in the livestream. For example, you can share your complete screen, a window of an application or documents under the visualizer as content of the second camera. The sound and the screen release are recorded.

HDMI output to beamer: The beamer is connected via HDMI. Depending on your system and requirements, you can decide whether it should display the contents of your screen 1:1 or be used as a second screen.

Tip Show PowerPoint presentation in window instead of full screen

A PowerPoint presentation can also be played back in a window, e.g. if other content such as the chat history from Zoom is to be displayed on the beamer in addition to the presentation. To do this, select the setting "View by an individual (window)" under "Set up screen presentation" under "Type of presentation". The presentation will then be displayed in a separate window when you start it and will no longer fill the entire display in full screen.
