Streaming per Uni-Streaming-Server
The IMT provides a streaming server (Wowza Media Server) to access live videos. The use of the streaming server is recommended for lectures with a number of participants of 80 to 800 students.
The video stream is broadcast live from an lecture hall (AM, L, O, G, C) of the UPB and is delivered to viewers via UPB's streaming server. This service does not provide a return channel. Alternative chat tools can be used simultaneously, but are not provided by the IMT.
- In the case of one-time only lecture, streaming is done to a previously created website (UPB subpage). Anyone with a link can call up the stream in their browser.
- For a series of live lectures the stream is streamed into a live channel of the UPB video portal. The video portal service must be applied for and activated beforehand: https://hilfe.uni-paderborn.de/Videoportal
Advantage here: The livestream is only accessible to a certain group of people, provided that the lecturers have subscribed and activated the users.
Requirements for using the service
- Contact the IMT by e-mail to imt(at)upb(dot)de
- Appointment arrangements unavoidable due to server load balancing
- Checking whether the lecture date of the classroom teaching can be used
- Alternatives of asynchronous teaching are not feasible.
Alternative to lecture hall streaming
Exceptions for streaming from home (using the freeware Open Broadcaster Software - OBS Studio) can be granted after a thorough review of the circumstances.
The maximum data rate of the streaming service is set by the IMT in order to reach students in areas with weaker network coverage. However, this cannot be guaranteed.
Live streaming is not recommended for courses in the summer semester 2020, only exceptional cases can be considered. Basically, asynchronous communication possibilities (e-mail, chat, quizzes, submission of exercises, feedback systems) should be used. These offer greater time flexibility and can also be used sensibly with limited bandwidth. When streaming, quality limitations and disturbances must be expected in case of overload.
