RTSP

The RTSP (Real Time Streaming Protocol) protocol 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 is usually used in conjunction with RTP.

Support for RTSP (and RTP) comes through LiveMedia.
