Real Time Streaming ProtocolRTSP
is the Real Time Streaming Protocol
developed by the IETF
and published as RFC 2326
. RTSP is a protocol
for use in streaming media
systems which allows a client to remotely control a streaming media server, issuing VCR-like commands such as "play" and "pause", and allowing time-based access to files on a server.
RTSP servers typically use RTP as the protocol for the actual audio/video data.
