What is RTP?

Real-time Transport Protocol (RTP) is a network protocol for delivering audio and video over IP networks. RTP is used in communication and entertainment systems that involve streaming media, such as telephony, video teleconference applications, television services, and web-based push-to-talk features. It provides end-to-end network transport functions suitable for applications transmitting real-time data, such as audio, video, or simulation data, over multicast or unicast network services. RTP typically runs over User Datagram Protocol (UDP).

How does this work?

RTP works by breaking up data into small packets, which are then sent over the network. When the packets arrive at their destination, they are reassembled in the correct order, allowing for real-time streaming of media. 

The protocol also includes features such as error correction and sequence numbering, which ensure that data is transmitted reliably and without interruption. As the packets travel through the network, they can be routed to different destinations and the media can be multicast to multiple recipients.
