Session Description Protocol (SDP)

Session Description Protocol (SDP) is a standard format used in multimedia communication to describe the details of a session, such as audio or video calls. It conveys information like the type of media, codecs used, network addresses, and timing, enabling devices and applications to negotiate and set up the connection properly. Think of SDP as a blueprint or specifications sheet that ensures all participants understand how to connect, what media will be exchanged, and how it will be transmitted, facilitating smooth and compatible communication in real-time multimedia sessions.
