RTCP Protocol - Definition, History and Explanation

The Real-Time Transport Control Protocol (RTCP) is a network protocol that works alongside the Real-Time Transport Protocol (RTP) to provide out-of-band control information for multimedia content delivery over IP networks. It is primarily used in multimedia streaming systems to offer feedback on the quality of service, enabling adaptive behavior based on network conditions. The protocol addresses challenges faced by early solutions for real-time media transport and provides valuable statistical and control data to improve the overall experience.
