Real Time Streaming Protocol is a network control protocol designed for use in entertainment and communications systems to control streaming media servers.
For example in France, the modem provided by Free ISP (Freebox) uses this protocol to broadcast TV/radio channels on the LAN. This module is required for any router between the modem and end-users.
