Real Time Streaming Protocol (RTSP) is a client-server multimedia presentation control protocol, designed to address the needs for efficient delivery of streamed multimedia over IP networks. It leverages existing web infrastructure (for example, inheriting authentication and PICS from HTTP) and works well both for large audiences as well as single-viewer media-on-demand. RealNetworks, Netscape Communications and Columbia University jointly developed RTSP within the MMUSIC working group of the Internet Engineering Task Force (IETF). In April, 1998, it was published as a Proposed Standard by the IETF

It uses a reliable control connection that sends RTSP messages in order to get information about the stream and to exchange commands, and then where possible uses an unreliable connection such as RTP to send the actual audio and or video data. Usually RTSP is delivered through TCP but is possible to use different protocols as SCTP or TLS. The usage through unreliable protocols (rtspu) is actively deprecated and hardly in use.

Variations

There are several variantions of RTSP:

  • RTSP 1.0
  • Windows Media RTSP
  • Real RTSP
  • Kasenna RTSP

Transport modes

  • RTP
  • RTP over TCP (Interleaved with RTSP)
  • RTP over SCTP (Using the stream id feature to lower the latency)
  • RTP over HTTP (a QuickTime extension to pass through proxies)
  • RDT (a RealRTSP extension)
