+### Decrease latency
+
+The RTSP protocol doesn't introduce any latency by itself. Latency is usually introduced by clients, that put frames in a buffer to compensate network fluctuations. In order to decrease latency, the best way consists in tuning the client. For instance, latency can be decreased with VLC by decreasing the `Network caching` parameter, that is available in the `Open network stream` dialog or alternatively ca be set with the command line:

+vlc --network-caching=50 rtsp://...

 in HLS, latency is introduced since a client must wait for the server to generate segments before downloading them. This latency amounts to 1-15secs depending on the duration of each segment, and to 500ms-3s if the Low-Latency variant is enabled.
