While similar in some ways to [[HTTP]], RTSP defines control sequences useful in controlling multimedia playback. While HTTP is [[stateless server|stateless]], RTSP has a state; an identifier is used when needed to track concurrent sessions. Like HTTP, RTSP uses TCP to maintain an end-to-end connection and, while most RTSP control messages are sent by the client to the server, some commands travel in the other direction (i.e. from server to client).

Presented here are the basic RTSP requests. Some typical [[HTTP request]]s, like the OPTIONS request, are also available. The default transport layer [[port number]] is 554<ref{{Ref name=":0" />RFC|2326}} for both [[Transmission Control Protocol|TCP]] and [[User Datagram Protocol|UDP]], the latter being rarely used for the control requests.
