How RTP Carrier Works
Basic Functionality
Technical overview
The Real-time Transport Protocol (RTP) operates as a network protocol designed to deliver audio and video over IP networks. It plays a vital role in communication and entertainment systems, such as telephony and video conferencing applications. RTP achieves this by breaking down multimedia data into packets, which are then transmitted over the network. Each packet contains a sequence number and a timestamp, ensuring that the data arrives in the correct order and at the right time. This method allows RTP to handle real-time traffic efficiently, providing users with a seamless multimedia experience.
Process flow
The process flow of RTP involves several key steps. Initially, the multimedia data is captured and encoded into digital format. RTP then packetizes this data, adding sequence numbers and timestamps to each packet. These packets travel across the network to their destination, where they are reassembled in the correct order. The receiving device decodes the data, converting it back into audio or video for playback. This process ensures that users experience minimal latency and high-quality media delivery, making RTP indispensable for real-time applications.
