The RTSP (Real Time Streaming Protocol) is a client-server application-level protocol for controlling the delivery of data with real-time properties. It establishes and controls either a single or several time-synchronized streams of continuous media, such as audio and video. It uses transport protocols such as UDP , multicast UDP, TCP , and RTP to deliver the continuous streams. In other words, RTSP acts as a network remote control for multimedia servers. Sources of data can include both live data feeds and stored clips.
