Accelerator Lead Keran Boyd was joined by Alex Giladi (Comcast), John Ellerton (BT Media & Broadcast), Michael Loftus (RTE) and Piers O’Hanlon (BBC) for a session exploring the development and implementation of ultra-low latency live streaming at scale. There was a focus on the technological advancements and industry collaborations designed to enhance viewing experiences.
Ellerton opened by reflecting on progress since last year’s demonstration of ultra-low latency streaming for premium sports. This year, attention shifted towards scaling the technology to meet the anticipated transition from traditional television to streaming across multiple countries, driven by consumer demand for improved services. Ellerton highlighted the technical challenges of scaling, outlining solutions such as the integration of new technology vendors like RTE and the adoption of the latest standards and protocols to ensure seamless delivery across varied networks and devices.
Giladi followed with a detailed technical analysis of the methods used to achieve ultra-low latency streaming. He described the deployment of CMCD v2 telemetry standards for monitoring and performance measurement, as well as advanced advertising approaches such as alternative MPD events. Giladi explained the system architecture, which incorporated encoders, CDN, and server-guided ad insertion, stressing the importance of industry-wide adoption to bring these solutions into full production. He further underlined the significance of collaborative work and highlighted future directions, including the optimisation of transport mechanisms and the potential benefits of adopting HTTP2 and HTTP3 for enhanced efficiency and cost-effectiveness.

DTG's Richard Lindsay‑Davies: "A once-in-a-lifetime shot to reshape TV"
The next decade will redefine broadcasting more profoundly than any transition since the arrival of television itself – and if broadcasters don’t grab it then YouTube will eat them all.
Delta Protocol: Live media reinvented
As project names go, ‘Delta Protocol’ might sound dramatic, more suited to an Andy McNab novel than a transformational technology initiative, but the reality is rather different. This Accelerator has suitably lofty aims, setting out to do no less than redefine video transmission by shifting from frame-by-frame delivery to scene understanding and semantic intelligence.
