The purpose of RTSP is to provide control over remote media servers. It is used when we click on Play, Pause, and so on, and can be used also to invite a new media server for viewing on the screen, for example, for a conference. While RTSP is the control protocol, the streaming itself is usually carried out by RTP—which carries the data—and RTCP —used for the monitoring of the data transfer.
The RTSP standard (RFC2326) does not define any transport protocol, but most implementations use TCP. RTSP is commonly used while watching IPTV. In this recipe we will learn how to monitor and troubleshoot these streams.
Getting ready
RTSP monitoring should be used in cases in which you experience transmission disturbances; for example, problems with the media player control or cases with connectivity...
