Real Time Streaming Protocol (RTSP)

Real Time Streaming Protocol (RTSP)

Abstract:

The traffic in the internet is becoming more and more involved with multimedia applications. To cope with such bandwith-demanding data, specific protocols have been created. The most difficult area is realtime (or realtimish) streams that enable us to make such things as videophonecalls and remote groupworks in much more efficient way.
The Real Time Streaming Protocol, or RTSP, is an application-level client –server protocol for control over the delivery of data with real-time properties.
RTSP provides an extensible framework to enable controlled, on-demand delivery of real-time data, such as audio and video. Sources of data can include both live data feeds and stored clips.
This protocol is intended to control multiple data delivery sessions, provide a means for choosing delivery channels such as UDP, multicast UDP and TCP, and provide a means for choosing delivery mechanisms based upon RTP.
The protocol defines the connection between a streaming media client and a streaming media server, and also provides a standard way for clients and servers from multiple vendors to stream multimedia content.
It takes advantage of Internet and Intranet infrastructure such as IP Multicast, RTCP and RTP, providing a means for choosing delivery mechanisms
