WISI, a member of the SRT alliance, has integrated the SRT protocol into the WISI Intelligent Headend Product family - Inca, Tangram or Chameleon. Video operators can now send or receive SRT streams using WISI products to lower latency and increase reliability.
What is SRT ?
SRT (Secure Reliable Transport) is a video transport protocol used to deliver high-quality, low-latency video across unpredictable networks.
Secure – Protects video streams using industry-standard encryption AES 128/256
Reliable – Recovers from severe packet loss
Transport – Dynamically adapts to changing network conditions
optimizes streaming performance across noisy or unpredictable networks while addressing security concerns and focusing on high performance video.
is designed to protect against jitter, packet loss and bandwidth fluctuations to help ensure the best viewing experience. This new transport protocol uses advanced low-latency retransmission techniques to protect streams against packet loss.
As video and audio packets are streamed between two endpoints, it detects and adapts to the real-time network conditions between the source and destination devices. SRT also supports end-to-end AES encryption to ensure streams are protected from contribution to distribution.
How does it work ?
SRT ensures easy firewall traversal by using a caller/listener handshake concept. The handshaking process used by SRT respects existing security policies by allowing outbound connections without requiring, permanent exterior ports to be opened in a firewall.
Chameleon, Tangram and Inca support all SRT transmission modes: caller, listener, or rendezvous.
