Tellyo releases V1.28 of Stream Studio with stream synch engine 

Tellyo has unveiled the latest version of its flagship Stream Studio solution. Stream Studio was launched less than two years ago and is used by customers including Liberty Global, ESPN and Sunset+Vine to create compelling live content that can be easily streamed to multiple digital and social media destinations.

V1.28 – codenamed Black Burst – is said to make frame-perfect switching of a live multi-camera production in the cloud a reality. This is thanks to a new stream synchronisation engine that precisely synchronises inputs from multiple camera feeds. V1.28 also includes Tellyo Intercom, which enables full duplex communication between the production team and talent. In addition, this latest version opens up more granular and precise control of Stream Studio’s audio mixing capabilities by merging the advanced and simple audio mixers into a single unified solution.

The built-in stream synch engine synchronises incoming multiple camera streams that share a common timestamping scheme. The engine supports SMPTE 12M SEI in-band timecode metadata (the digital VITC/LTC) and wallclock NTP/PTP timestamps. With incoming streams that include the timing information users can now switch a remote multi-camera production live in the cloud, without having to worry about cameras getting out of sync.

Stream Studio even supports multiple timing schemes within the same production. Depending on internet connectivity, either an adaptive or static buffering mechanism can be chosen.

Robert Szabo-Rowe is senior vice president, engineering & product management with The Switch, a long-standing Tellyo partner. “This update is critical and the technology lets us create professional, frame perfect, multi-camera sports productions,” he noted. “We’ve never been able to do that live in the cloud before. By removing the issue of video packets arriving with different and inconsistent delays, we can now give our audience a much higher quality and more engaging experience.”

Tellyo COO Jakub Majkowski said: “We’re excited to introduce the stream synch engine, as well as improving Stream Studio’s comms abilities by making two separate partyline channels available – Talkback for the ‘core’ production crew and IFB for talent. Add in the configuration enhancements to the audio mixer, and you can see why Stream Studio keeps growing as a platform and is receiving so much industry attention. Our ambitious product roadmap keeps delivering on real-world customer feedback, and there’s much more to look forward to in 2022.”
