Video and Web Conferences

Members of Philipps-Universität Marburg can use the following systems for video and web conferences in teaching, research and administration.

Note: The web conferencing service Adobe Connect (in ILIAS: object "Online Meeting") can currently only be used to a limited extent, as it is not possible for the operator, the DFN-Verein, to expand its capacity. All three systems meet the necessary requirements for data protection and IT security. However, they differ in terms of their functions and possible application scenarios:
