Wowza Announces SRT Support in Wowza Streaming Engine

Teradek and BlueFrame Technology Validate SRT for Reliable Video Transport Across Unstable Networks

Golden, Colo(28 Aug 2017)

Wowza Media Systems, the recognized gold standard in streaming, today announced the support of SRT (Secure Reliable Transport) with a new update to its Wowza Streaming Engine software, with version 4.7.2. As an open source alternative to expensive and proprietary video transport technologies, customers can now use SRT to ingest high quality video across sub-optimal networks, into any Wowza Streaming Engine origin server for delivery. The inclusion of SRT also reinforces the reliability for streams originating in networks with high congestion or low bandwidth availability.

In recent benchmark tests of SRT, Wowza noted greater reliability of throughput and packet loss, and improved bandwidth utilization when encountering network bandwidth fluctuations. In long-haul transport of video from Germany to Australia, using a consumer DSL connection, testing showed a 7.5x increase of throughput with SRT, compared to RTMP connections over TCP. 

"Teradek is delighted to implement SRT across our current line of products,” said Jon Landman, Vice President of Sales at Teradek. “Today we conducted a test stream from a Cube 755 encoder with SRT to Wowza Streaming Engine, and despite 10% packet loss, the feed arrived perfectly clean and clear. The technology is absolutely groundbreaking."

“The addition of SRT to our Wowza Streaming Engine workflows enables customers to more reliably deliver low-latency video from anywhere,” said Chris Knowlton, Partner and Chief Strategy Officer at BlueFrame Technology. "This is especially true at remote and older venues, where production teams are routinely broadcasting over limited-bandwidth networks and cellular data connections."

SRT can deliver seamlessly across the technology stack, with fixed end-to-end latency that doesn’t build up over time. The protocol offers an alternative to TCP connections through a reliable UDP transport solution with packet loss recovery; end-to-end security with AES encryption; network health monitoring between endpoints; and simplified firewall traversal.

As a co-founding member of the SRT Alliance, which was announced at NAB 2017, Wowza will continue to incorporate SRT throughout its technology offerings, beginning with Wowza Streaming Engine. Jointly with Haivision, Wowza will host a webinar to discuss the benefits of SRT on Wednesday, August 30, 2017 at 11 a.m. EST. To register for the webinar, please visit:
