Videoconferencing service, for example, to hold project meetings with research colleagues or project partners and to look through documents online or to hold events with a partner institute at a national or international level.
DFNConf for video conferencing and teleteaching
You have to review documents with a research colleague or a project partner from industry, but do not have time for a business trip?
You would like to hold a course together with a partner institute in Germany or abroad?
In such cases, a video conference is the easiest and often cheapest way to communicate with the partners not only audiovisually, but also to present digitally available documents and, if necessary, to work on them together.
The new platform of the video conferencing service DFNConf is now available at KIT. With this service, all KIT staff members can set up, organize, and conduct video conferences with guests and partners worldwide easily and platform-independently.
The new PEXIP-based system relies fully on the WebRTC standard for PCs, which allows easy access (even across firewalls) via a web browser. One of the DFN's main concerns when selecting the product was to remain compatible with all VC systems/protocols. All common standards, such as old room systems, SIP and telephony are still used very well. Apps (Pexip) are also available for mobile clients under Android and iOS. If you want to get to know the service from scratch, you can get a first overview here. Details can be found in the presentation held during the VCC workshop: https://vcc.zih.tu-dresden.de/files/termine/ws_2018-06-07/Vortraege/VCC-Workshop2018-CM.pdf .
WebRTC, the technology used for PC-based communication, is a standard currently agreed upon by most browser manufacturers. This standard is constantly being further developed, so that in the future new possibilities will be added continuously, such as higher bandwidth tolerance, better resolutions and new video codecs. However, this development is dependent on many factors and the implementation of the individual functions is not synchronized by all browser manufacturers.
Further information and services in the field of video conferencing can also be found at the Competence Center for Video Conferencing Services at the TU Dresden .
For the integration of your "old" equipment (e.g. set-top boxes from Polycom) into the Global Dialing Scheme (GDS), the SCC operates a so-called gatekeeper where you can register your equipment. This registration is useful, for example, if you want to use the video conference service of DFN or if your video conference system is to be accessible via a so-called E.164 number. Please contact your supervisor for an entry. Alternatively, you can also enter the DFN public gatekeeper pgk.vc.dfn.de for access to the service.
DFNConf - Videoconference the smart way
DFN offers an organizer portal where videoconferences can be managed by the organizer himself. Only if you want to set up and organize a videoconference yourself you need this portal. For the pure participation the address of the meeting room, which you get from the organizer, is sufficient.
The access is via the purple button Veranstalter-Login on the top of the website DFNConf .
Auf den folgenden Seiten können Sie dann das
Karlsruher Institut für Technologie (KIT) auswählen, sich dann mit Ihrem KIT-Account einloggen.
You will reach on the portal's homepage, where you can manage your events. Alternatively, you can access the Adobe Connect server of DFN directly via DFNconf - Organizer Portal Web Conferences with Adobe Connect.
If you click on NEW MEETING ROOM + or NEW LECTURE +, you can create new conferences. Now enter the Name and the Host PIN. All other settings are preselected and hidden.
If you want a meeting room without PIN, leave the field for the organizer pin empty and go to More settings (Show) and set Allow guests to No. Please note that in meeting rooms without PIN all participants have organizer rights. You can find more information about this at ttps://docs.pexip.com/admin/pins_hosts_guests.htm .
With More Settings and a click on Show you can display all settings and change them if necessary. If you click on the SAVE button, the conference is created and you will return to the overview.
If you click on the Room Number in the overview, you enter the conference directly as organizer. For inviting guests to a conference you will find an Invitation (de) or a Invitation (en) in german and english directly on the overview page, which you can copy and send e.g. via email. This template contains all possible access paths for the selected conference.
The different conference types differ in the layout options, i.e. in the distribution and number of areas for video images and presentation. For more information, see the link in the top right-hand corner:
At IMPORT MCU CONFERENCE + you can transfer room numbers from the "old" structure to the new one. For example, the conference number can only be transferred in the form 97958350, i.e. without the leading 0049100.

In order to use the service, e.g. in a web browser, at least one audio device e.g. a headset and a camera, must be physically connected to the system and use must also be enabled in the browser.
DFNConf Tips (Pexip)
The DFN also provides an FAQ.
- Minimum requirements
- test call
- Recording and streaming
- Set primary speaker position
- Set up guest pin
- Microsoft Edge
- Internet Explorer
- Direct dial a conference
- Transmitted videos jerk
- Device pairing with H.323 room systems
- PIN-less meeting rooms
In order to use the service, e.g. in a web browser, at least one audio device, such as a headset and a camera, must be physically connected to the system and use must also be enabled in the browser.
The meeting room number 9791 has been unlocked as a test room.
You can reach the test room via
Web App: https://conf.dfn.de/webapp/conference/9791
SIP: 9791@conf dfn en
Skype for Business: 9791@vc dfn en (please note the notes for Skype for Business)
With the call you can test the connection to the meeting server, your video and your microphone. You will receive some instructions and your video and audio will be sent back to you (with a 2 second delay to hear yourself). After about 20 seconds, the connection will be automatically terminated.
Recording and streaming:
Currently, there is no possibility of a videoconference for streaming or recording. DFN e.V. is working on a solution. Until then you can of course continue to connect your meeting rooms to external streaming providers. This is possible for Youtube, Facebook, Periscope and local Wowza installations. You can find corresponding instructions at https://docs.pexip.com/admin/integrate_streaming.htm .
Set primary speaker position:
The client has a new function called Spotlight. This allows to mark participants of the conference so that they remain in a primary speaker position (large in the picture) in a conference. Conference Hostss can find the function by clicking on a participant, in the following menu on Spotlight.
Set up Guest Pin:
In addition to the Host PIN, it may be advisable to assign a guest PIN (enter "Yes" under "Allow guests:"), since without such a PIN, access to the room is only possible if the host is already present. If you select "No" at "Allow guests:", all participants are "Host" and need the "Host PIN".
Microsoft Edge currently still has screen sharing issues and should not be used for screen sharing sessions.
Microsoft Internet Explorer cannot be used because WebRTC is not supported.
Direct dial a conference
In order to enter a conference directly via the browser, you must transmit your name (display name) in addition to the PIN:
Transmitted videos jerks
Please select the option "View full motion presentation" in the client. It is recommended to make a corresponding default setting in the client in the settings (...) and then in "Advanced Settings".
Device Pairing with H.323 room systems
With device pairing, extended functions can be controlled from e.g. Windows systems and "used" on H.323 systems. When specifying the device to be "paired", you should not forget h323: before the IP address.
PIN-less meeting rooms
As of now, the assignment of a Host PIN for meeting rooms in the video platform is optional. For a meeting room without PIN, leave the PIN field blank and deactivate guest participation. Please note: in meeting rooms without PIN all participants have host rights. You can find more information about this at https://docs.pexip.com/admin/pins_hosts_guests.htm.
Adobe Connect: Online-Meeting und -Kollaboration
KIT has concluded a service agreement with DFN-Verein for the use of the DFNconf conference service in the Deutsches Forschungsnetz. Therefore, you can use the Adobe Connect service (web conference) of DFN free of charge:
Please log in via "Registration via DFN-AAI or DFNConf" at https://webconf.vc.dfn.de/. Here you can use your KIT account. The service for the DFN services is provided by the SCC.
Adobe Connect is an online application that enables you to instantly meet with colleagues, project team members, and students - anytime, anywhere. All you need is the Adobe Flash plug-in and a browser or an app for your smartphone and you can enter a meeting room, view and join meetings online. More and more components of Adobe Connect does not use Flash anymore. In a meeting, you can view a variety of materials, including PowerPoint slides, digital video, PDF documents, Flash simulations and other types of media.
On the server webconf.vc.dfn.de a maximum of 200 users can participate in meetings at the same time.
Adobe Connect has an easy-to-use user interface. The components of the meeting can be freely arranged and configured by the host in a simple way. Uploaded PowerPoint presentations, for example, are automatically converted and are then immediately available.
All communication between the Adobe Connect server and the client computers is secured by SSL encryption and the software runs on DFN servers. This ensures a secure exchange of data, video and audio streams.
Adobe Connect Meeting is also optimized for smaller bandwidths. The system can also be used very well with DSL.
If you want to use the system or just want to get to know it, please contact the supervisor.
Video conference etiquette
Especially for multipoint conferences it is important to maintain a high level of language discipline. In this way, you avoid that during voice-activated switching
- constantly switch between the locations or
- switch over exactly when you do not want to.
Avoid any noise as far as possible.Location sign
At each location a sign with the name of the location should be constantly visible in the video image.
Introducing the participants
Each participant should always introduce himself personally at the beginning of the event.
Preparation of the event
At the beginning of the event the connection should be switched and all equipment (cameras, microphones, projectors, ...) should be tested and ready. Always take enough time for the preparation and calculate possible problems.
Avoid panning and zooming. If necessary, use multiple cameras and switch views. Test this in advance. Do not make any more changes to the configuration during the event.
The necessary data (room number,URL, e-mail addresses and telephone numbers of the organisational and technical contact persons, telephone number of the conference room) of all conference locations should be available at all locations much earlier. A mobile wireless telephone in the conference rooms often makes it much easier to solve problems. A distributed chat tool facilitates "silent" communication between the locations.
A written agenda for the events should be available at each location. This and all other equipment should, if possible, be made available to all participants a long time before the event.
A punctual start to avoid unnecessary (sound) disturbances goes without saying.
Remember that you can always be seen and heard. When you speak, always look into the camera and speak loudly and clearly. Avoid major and/or constant body movements and any activities that are not directly related to the event. Act as if all participants were gathered in the same room.
Colour design and lighting
Avoid garish colours (especially in the red area) and moving dress patterns. The tree moved by the wind, which can be seen through the window in the background, is just as bad as the poppy patterned wallpaper or the well-equipped bookshelf in the background. A darker grey-blue, for example, can be chosen as the background colour. Make sure that the faces of the participants are sufficiently illuminated. Avoid strong differences in brightness in the room or the sunlit windows in the video image. Pinstripes in a suit, on the other hand, are not a problem.
If you are working with e.g. diagrams, posters or whiteboards for illustration purposes and this is recorded with a video camera, please remember that due to the resolution of the video technology only larger fonts can be read and coarser thicker lines and structures are clearly visible.Optimal audio equipment
For a general avoidance of any kind of noise, automatic mixers are used, which activate the sound only when a sound profile typical for the language is present and raise or limit this speech signal to a predefined level. Optimal are devices that also have an automatic noise reduction and echo cancellation. In this case, a separate echo cancellation should be provided for each microphone used. If media are frequently played in, it is useful if the audio signal of these sources is automatically reduced when a speech signal is present (audio ducking).
For locations with only one participant, for example, a headset or lapel microphone can be used.
For groups, an appropriate number of micros and/or higher quality boundary microphones should be used. For audience questions, radio microphones have proven to be a good solution. They are passed around and thus automatically ensure a discipline of speech.
