SRT (Secure Reliable Transport) is an open-source transport protocol and C++ library for ultra-low-latency live video and audio streaming over unpredictable IP networks. It provides AES encryption, packet loss recovery via ARQ and FEC, connection bonding, and adaptive congestion control.

Use cases

• stream live video with sub-second latency over the internet
• send video contribution feeds between broadcast sites over lossy networks
• encrypt live media streams in transit
• recover from packet loss during live streaming
• bond multiple network connections for resilient video transport
• transfer bulk data reliably over UDP

When to choose

• you need low-latency live video delivery over the public internet
• your network has jitter, congestion, or packet loss
• you need encrypted media transport with an open, industry-standard protocol
• you are building broadcast contribution or distribution workflows

When to avoid

• you need simple file download over HTTP where TCP/TLS suffices
• you need web browser playback directly without a gateway or transcoder
• your use case tolerates high latency and simpler protocols like RTMP or HLS are adequate
