Softvelum SRT products

Secure Reliable Transport (SRT) is a UDP-based transport technology that optimizes streaming performance across unpredictable networks.

• SRT detects and adapts to the real-time network conditions between the two endpoints.
• SRT helps compensate for jitter and bandwidth fluctuations due to congestion over noisy networks.
• Error recovery mechanism minimizes the packet loss typical of Internet connections.
• AES 128/256 bit encryption is also supported for end-to-end security.

Softvelum products allow building full chain of live delivery via SRT.
