# Overview of Services for Digital Teaching

This source provides a comparative overview of the conferencing, presentation, and streaming tools available for digital teaching at the Universität Greifswald. It outlines the technical capabilities, participant limits, and interactivity levels of various services provided by the URZ.

## Tool Comparison Matrix

| Service | Max Participants | Audio/Video/Screen | Interactive | Chat | Recording | Notes |
| :--- | :--- | :--- | :--- | :--- | :--- | :--- |
| Telephone Conference | 3+ | Audio only | Yes | No | No | Internal |
| Pexip / DFNconf (Conference) | 23 (+50 Audio) | Yes | Yes | Yes | No | External |
| Jitsi Meet | 35 | Yes | Yes | Yes | No | Internal |
| BigBlueButton | 225 | Yes | Yes | Yes | Yes | Moodle activity |
| Pexip / DFNconf (Lecture) | Unlimited | Yes | No | Yes | Yes | External |
| GrypsTube | Unlimited | Yes | No | No | Yes | Video service |

## Key Technical Constraints
- **External Service Load:** Services marked as "external" (specifically Pexip / DFNconf) may experience significant performance degradation during peak hours:
    - 10:00 – 11:00
    - 13:00 – 15:00
- **Support:** All Campus-IT issues are handled by the [[universitatsrechenzentrum-urz]] via the [[groupware]] ticket system or the hotline (ext. 1420).
