# Livestreaming

Livestreaming is used to reach a very large number of students simultaneously via audio and video.

## Technical Characteristics
- **Latency**: There is a signal delay (typically **10 to 30 seconds**) because the signal must be buffered on the streaming server to ensure smooth playback.
- **One-Way Communication**: A livestream is an outgoing channel only.
- **Back-channel Requirement**: Because of the latency and one-way nature, a separate "back-channel" (such as a text chat) is required for any interaction with the audience.

## Recommended Tool
The URZ points to **DFNconf/Pexip** for conducting livestreams via the DFN (Deutsches Forschungsnetz).
