Real-Time Transport Protocol (RTP)
What is the Real-time Transport Protocol (RTP)?
Real-time Transport Protocol (RTP) is a network protocol for the delivery of audio and video over the internet. It is designed to provide end-to-end network transport functions suitable for applications transmitting real-time data, such as audio and video.
RTP is used in conjunction with the Real-time Transport Control Protocol (RTCP), which is used to monitor the quality of the data transmission. RTP provides the actual delivery of the media, while RTCP is used to provide feedback on the quality of the transmission and to provide other control information.
RTP is a packet-based protocol, which means that it breaks the media stream into packets for transmission over the network. Each packet is given a sequence number, which allows the receiver to reassemble the packets in the correct order. RTP also includes a timestamp, which allows the receiver to synchronize the audio and video streams.
RTP is widely used in a variety of applications, including voice over IP (VoIP), video conferencing, and streaming media. It is supported by many media players and servers, and it is often used in conjunction with other protocols, such as RTSP and SIP, to deliver audio and video content over the internet.
What applications use the Real-time Transport Protocol?
Real-time Transport Protocol (RTP) is widely used in a variety of applications that require the delivery of real-time audio and video over the internet. Some examples of applications that use RTP include −
Voice over IP (VoIP) − RTP is commonly used in VoIP systems to transmit audio over the internet.It allows for the real-time delivery of voice calls with low latency.
Video conferencing − RTP is often used in video conferencing systems to transmit audio and video in real time. It allows for the synchronous communication of multiple participants.
Streaming media − RTP is used in many streaming media applications to deliver audio and video over the internet. It is often used in conjunction with other protocols, such as RTSP and HTTP, to stream media to clients.
Telephony − RTP is used in many telephony systems to transmit audio and video between devices. It allows for the real-time communication of multiple parties in a call.
Broadcast television − RTP is used in some broadcast television systems to transmit audio and video over the internet. It allows for the delivery of live television streams to viewers.
Overall, RTP is a widely used protocol for the delivery of real-time audio and video over the internet.It is supported by many media players and servers and is an important part of the infrastructure that enables the streaming of multimedia content.
Here are some technical details about Real-time Transport Protocol (RTP)
Packet-based − RTP is a packet-based protocol, which means that it breaks the media stream into packets for transmission over the network. Each packet is given a sequence number, which allows the receiver to reassemble the packets in the correct order.
Timestamps − RTP includes a timestamp, which allows the receiver to synchronize the audio and video streams. The timestamp is used to calculate the time at which each packet should be played back.
Header format − RTP packets have a fixed header format, which includes a version number, a payload type identifier, a sequence number, a timestamp, a synchronization source identifier (SSRC), and a list of contributing source identifiers (CSRCs). The header is followed by the actual media data.
Transport protocol − RTP uses User Datagram Protocol (UDP) as its transport protocol. UDP is a connectionless protocol that provides a lightweight and efficient way to transmit data over the internet.
Security − RTP does not include any built-in security measures. However, it can be used in conjunction with other protocols, such as Secure Real-time Transport Protocol (SRTP), to provide encryption and authentication of the media stream.
Error correction − RTP does not include any error correction mechanisms. It is designed to transmit real-time data with minimal delay, and it relies on the underlying transport protocol to handle lost or damaged packets.
