RTSP (Real-Time Streaming Protocol) allows to control multimedia streams delivered, for example, via RTP. Control includes absolute positioning within the media stream, recording and possibly device control.

The Realtime Transport Protocol (RTP) is both an IETF Proposed Standard (RFC 1889) and an International Telecommuncations Union (ITU) Standard (H.225.0). It is a packet format for multimedia data streams. RTP is used by both RTSP and H.323 for the data portion of these protocols.
