What is RTP?

RTP (Real Time Transport Protocol) is a streaming protocol that defines a standardized packet format for delivering audio and video over IP networks. RTP is used with RTCP (Real Time Transport Protocol Control Protocol) in RTSP streaming.

RTP protocol provides:

  • Jitter compensation and detection of out-of-sequence arrival in data that are common during transmissions on an IP network. 
  • Data transfer to multiple destinations through IP multicast.
  • Audio smoothing: packet loss that results in less than a second of lost audio data can be made unnoticeable with suitable error-concealment algorithms.
