SRT Open Source Video Transport Project Adds Fast File Transfer and Stream Multiplexing

Widely supported for low latency video streaming, freely available SRT now helps organizations reduce infrastructure cost with support for file transport and simplified IT workflows

AMSTERDAM, NETHERLANDS (IBC 2017) – September 15, 2017 – The SRT Alliance, an open-source initiative dedicated to overcoming the challenges of low-latency video streaming, announces the availability of the latest version (1.3) of the SRT video transport protocol. The new version supports encrypted fast file transfer of VOD files and the multiplexing of streams within the same network port.

Announced  at NAB, the SRT Alliance was founded by streaming video industry leaders Haivision and Wowza, in an effort to offer SRT as an open source alternative to proprietary technologies. SRT has since been endorsed by over 40 leading companies. Combining UDP-like performance, fast packet loss recovery, simplified firewall transversal and encryption, SRT has become the most rapidly adopted technology in the video streaming industry.

The latest release of SRT version 1.3, today available on GitHub, features:

  • Fast File Transfer: Broadcasters, media companies, and anyone interested in sending large files efficiently over public internet connections can now transmit files securely, quickly, and reliably, thereby reducing the costs typically associated with alternative commercial file transfer technologies.
  • Stream Multiplexing: SRT’s firewall traversal techniques are now augmented by supporting multiple connections on the same UDP port, simplifying the challenges of complex streaming workflows.

“In only a few short months, SRT has disrupted the industry with open-source technology designed to overcome the fundamental challenges of low latency video and bandwidth optimization over the internet,” said Peter Maag, chief marketing officer, Haivision. “Our latest release of SRT evolves the protocol beyond just live streaming to new use cases with support for fast file transfer, applicable within broadcast and many other markets. We’re looking forward to the continued development of the technology to support the evolving challenges across industries.”
