New integrations with the open-source Secure Reliable Transport (SRT) protocol are about to make it easier for broadcasters to ingest live or file-based content for cloud-based production workflow without fiber or satellite links, according to members of the SRT Alliance.

In the run-up to IBC, Haivision, the original developer of SRT, announced the SRT Hub, a low-latency media routing service on Microsoft Azure designed to connect systems from any geographic location to cloud infrastructure, and released the SRT Hub SDK, allowing third-party integration. Integrated components providing IO with the SRT Hub cloud are known as “hublets,” and may include media-processing capabilities.

Haivision said vendors including Avid, Cinegy, Haivision, LightFlow, Microsoft, Telestream and Wowza Media Systems have signed onto the new SRT Hub Partner Program and will be demonstrating the first hublets at IBC 2019.

The SDK is available now from Haivision and will be distributed on GitHub “shortly,” the company said.

Ingest IP Media ‘from Anywhere’

Avid and Microsoft will offer a tech preview of on-premise and cloud-based workflows using SRT Hub along with Avid FastServe Stream to ingest IP-based SRT streams “from anywhere,” Avid and Haivision officials said.

The connections, which use the Microsoft Azure backbone to move content from the field to a broadcaster’s MediaCentral system, are said to be secure and extremely low-latency, free of buffering and other delays. SRT Hub uses the Microsoft IoT framework to communicate with edge devices including video encoders and gateways, Haivision said.

“IP has opened the door to mobile content creation and consumption, but guaranteeing quality for both creators and consumers has been a serious, ongoing challenge,” said Avid Director of Product Marketing Ray Thompson in a prepared statement. “By integrating SRT and Haivision SRT Hub, Avid will be able to deliver on the ability to get news, sports and live content from anywhere into MediaCentral and out to social media channels and broadcasts.”

The Avid tech preview will be demonstrated during IBC, which runs at the Amsterdam RAI from September 13–17.

Also at IBC, Wowza will debut its Wowza Hublet for SRT Hub, which will enable low-latency streaming “from any location to any device, anywhere,” according to a statement from Barry Owen, Wowza VP of solutions engineering.

And LightFlow will show what it called its second SRT Hublet as part of its LightFlow Suite. “We continue to enable the LightFlow Suite within Haivision SRT Hub, where customers are able to create live video streams with a three-second glass-to-glass latency, from broadcast contribution to massive delivery over the Internet,” said LightFlow CEO Miguel Serrano in a statement.

Haivision will present an “SRT Hub Technical Overview” at the IBC conference on Sunday, September 15 at 1:30 p.m. in Room G104. The session is free to attend, but advance registration (via the above link) is required.
