Real-Time Transport Protocol (RTP)

RTP (RFC 3550) is a generic transport protocol for real-time media streams such as audio or video. RTP is typically run over UDP. RTP's services include timestamps and identification of media types. RTP includes RTCP (RTP Control Protocol), whose primary use is to provide feedback about the quality of transmission in the form of Receiver Reports.

RTP is used as a framing protocol for many real-time audio/video applications, including those based on the ITU-T H.323 protocol and the Session Initiation Protocol (SIP).
