-### Usage as RTSP Proxy
+### RTSP proxy mode
 
-An RTSP proxy is usually deployed in one of these scenarios:
-* when there are multiple users that are receiving a stream and the bandwidth is limited, so the proxy is used to receive the stream once. Users can then connect to the proxy instead of the original source.
-* when there's a NAT / firewall between a stream and the users, in this case the proxy is installed on the NAT and makes the stream available to the outside world.
