SRT (Secure Reliable Transport) Protocol

Description

SRT is an open-source video transport protocol that utilizes the UDP transport protocol. It provides connection and control, reliable transmission similar to TCP, while maintaining low latency. SRT supports packet recovery and encryption using AES, making it suitable for secure and reliable video streaming applications.
