RTP stands for Real-time Transport Protocol. It is a communication protocol that facilitates the transmission of audio, video, and data in real-time over IP (Internet Protocol) networks. RTP is primarily used in applications that require a continuous and synchronized delivery of media streams, such as streaming audio and video conferencing.
The protocol is designed to provide end-to-end delivery of multimedia data while minimizing latency, jitter, and packet loss. RTP operates in conjunction with the RTP Control Protocol (RTCP), which is responsible for monitoring the quality of the transmitted data and providing feedback on network conditions.
RTP operates on the transport layer of the Internet Protocol Suite (OSI model), utilizing User Datagram Protocol (UDP) for data transmission. It employs a mechanism for numbering and sequencing packets to ensure that they are delivered in the correct order at the receiver's end.
RTP also includes features for payload type identification, timestamping, and sequence number synchronization. These features enable the receiver to reconstruct the media stream accurately and synchronize it with other media elements, such as audio and video players.
Overall, RTP plays a crucial role in enabling real-time communication and multimedia streaming applications, contributing to the seamless transmission and reception of audio, video, and data over IP networks.
