RTSP (Rao, Lanphier, Stiemerling, Schulzrinne, & Westerlund, 2011) is a connectionless data flow protocol in real time used to define how information is sent between client and server, enabling the delivery of previously stored or live media content to be initiated and controlled.
Similar to HTTP (hypertext transfer protocol): when possible, RTSP reuses HTTP concepts.
To summarize their response, they said RTSP
and other non-HTTP protocols weren't being requested at all, but RTMP was still a valid industry solution.

The specification also makes it clear that the UE uses RTSP commands to communicate with the MCF for the purpose of media control.
One reason for this is because RTSP
delivery requires less bandwidth to send down the same video file, and another reason is the way the two handle lost packets.
