The rtsl file extension is related to RealNetworks, which utilize the IETF standardized Real Time Streaming Protocol (RTSP) but only to manage the connection. The actual audio data is sent with their own proprietary RDT protocol, which they initially kept secret. Recently, some specifications for the RDT protocol have been made public through the Helix Community project. The open-source MPlayer project eventually developed a means of playing the RDT streams.
