RTP (Real-time Transport Protocol) is a network protocol used for transmitting real-time media, such as audio and video, over IP networks. It is widely used in applications such as VoIP, video conferencing, streaming media, and online gaming. RTP works by breaking the media data into small packets, each of which is transmitted separately over the network. It uses a dynamic payload type field to indicate the type of media data being transmitted. RTP (Real-time Transport Protocol) also provides timestamp information to help receivers reconstruct the original timing of the media data, as well as sequence numbers to ensure the correct order of packet delivery.
