RECORD This method initiates recording a range of media data according to the presentation description. When the range parameter is omitted, the pause occurs immediately and indefinitely. A range parameter on a PAUSE request specifies when to pause. The request contains an aggregate or media stream URL. PAUSE A PAUSE request temporarily halts one or all media streams, so it can later be resumed with a PLAY request. If no range is specified, the stream is played from the beginning and plays to the end, or, if the stream is paused, it is resumed at the point it was paused. The URL may be the aggregate URL (to play all media streams), or a single media stream URL (to play only that stream). Play requests can be stacked by sending multiple PLAY requests. PLAY A PLAY request will cause one or all media streams to be played. Transport: RTP/AVP unicast client_port=8002-8003 Transport: RTP/AVP unicast client_port=8000-8001 Each media stream must be configured using SETUP before an aggregate play request may be sent. The server reply usually confirms the chosen parameters, and fills in the missing parts, such as the server's chosen ports. This specifier typically includes a local port for receiving RTP data (audio or video), and another for RTCP data (meta information). The request contains the media stream URL and a transport specifier. This must be done before a PLAY request is sent. SETUP A SETUP request specifies how a single media stream must be transported. C->S: DESCRIBE rtsp:///media.mp4 RTSP/1.0Д¬ontent-Base: rtsp:///media.mp4 The media stream URLs are either obtained directly from the SDP control fields or they are obtained by appending the SDP control field to the aggregate URL. In the typical case, there is one media stream each for audio and video stream. Among other things, the presentation description lists the media streams controlled with the aggregate URL. This reply includes the presentation description, typically in Session Description Protocol (SDP) format. Public: DESCRIBE, SETUP, TEARDOWN, PLAY, PAUSEДESCRIBE A DESCRIBE request includes an RTSP URL (rtsp://.), and the type of reply data that can be handled. OPTIONS An OPTIONS request returns the request types the server will accept. The default transport layer port number is 554 for both TCP and UDP, the latter being rarely used for the control requests. Some typical HTTP requests, like the OPTIONS request, are also available. Presented here are the basic RTSP requests. 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. While HTTP is stateless, RTSP has state an identifier is used when needed to track concurrent sessions. While similar in some ways to HTTP, RTSP defines control sequences useful in controlling multimedia playback.

The RTSP server software from RealNetworks, for example, also used RealNetworks' proprietary Real Data Transport (RDT). However, some vendors implement proprietary transport protocols. Most RTSP servers use the Real-time Transport Protocol (RTP) in conjunction with Real-time Control Protocol (RTCP) for media stream delivery. The transmission of streaming data itself is not a task of RTSP. Main article: Real-time Transport Protocol RTSP 2.0 is based on RTSP 1.0 but is not backwards compatible other than in the basic version negotiation mechanism, and remains a 'Proposed Standard'. RTSP 2.0 published as RFC 7826 in 2016 as a replacement of RTSP 1.0. The Proposed Standard for RTSP was published as RFC 2326 in 1998. The two drafts were merged for standardization by the Multiparty Multimedia Session Control Working Group (MMUSIC WG) of the Internet Engineering Task Force (IETF) and further drafts were published by the working group. The first draft was submitted to IETF in October 1996 by Netscape and Progressive Networks, after which Henning Schulzrinne from Columbia University submitted 'RTSP'' ('RTSP prime') in December 1996. RTSP was developed by RealNetworks, Netscape and Columbia University. 3.12 Embedded (Interleaved) Binary Data.
