SRT for Low-Latency Streaming

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 

How does it work ? 

SRT

 

  • 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.

  • 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.
