transport, making it a powerful solution for high- quality, IP-based, broadcast workflows. CHRIS SCHECK: Due to the laws of physics, transporting any kind of signal over long distances involves some delay, as no signal can travel faster than the speed of light. To mitigate syncing issues, the appropriate amount of delay can be added to audio essences, which often travel faster and result in a delayed output. Satellite uplinks are of little help because they also induce delays. Any kind of processing involves a short delay – a latency – which is why sending an essence to a device or app on a continent elsewhere in the world for processing then back again should be avoided at all costs. To this end, solutions such as .edge provide local processing. This happens on the edge of the network – before essences are sent out for production purposes – so this approach is called edge processing. By saving lots of milliseconds or frames, this can optimise latency.

WHERE WILL IP SIT IN BROADCAST ΄ S FUTURE?
IP technology is not squeezed among current trends, but is instead part of the backbone of future broadcasting and media distribution in terms of achievability, innovation and adaptability. JOHN WASTCOAT: The shift to IP- and cloud-based workflows is accelerating as broadcasters respond to increased viewer demand for live programming, personalised content and improved profitability. IP enables efficient, collaborative workflows, allowing media organisations to produce, distribute and monetise content globally with fewer physical constraints. This aligns with the industry’s broader adoption of cloud and virtualised workflows, and provides flexibility to scale resources on demand and integrate easily across platforms. Innovations in 5G and edge computing further enhance IP’s reliability and reduce latency, making it ideal for live broadcasting, OTT streaming and interactive content. Tools like the SDVP optimise IP-based workflows with advanced error correction, adaptive bit-rate streaming and multi-protocol support, ensuring high-quality, low-latency video transport. As IP continues to offer flexibility, scalability and cost efficiency, it’s becoming the cornerstone of future broadcasting and media infrastructure, driving the industry’s digital transformation. DARREN GOSNEY: While IP adoption is on the rise, it’s important to recognise potential challenges, including bandwidth requirements, infrastructure investment and the need for more skilled IT personnel. These factors will almost certainly influence the pace at which IP technology is embraced by companies across the landscape of broadcasting and media.
ADAM VANN: IP technology will supersede as the mainstay for the future of broadcasting and media. The industry is moving towards more flexible, scalable and economical systems. Several broadcasters and production companies have transformed their workflows to become almost entirely IP-based, thereby providing greater flexibility and cost efficiency. The momentum already built up for switching from traditional SDIs to 5G digital IP is now ramping up further. Broadcasters can also use IP to transfer from one video format to another, increasing bandwidth as the demands for high-resolution video (4K and 8K) increase, as well as for new technologies such as VR and AR. On-demand scaling of bandwidth and processing power is poised to be high up among the host of reasons why IP is likely to remain at the heart of content provision. On top of this, IP allows remote production and cloud-based workflows, which peaked during the pandemic. As production needs become increasingly global, IP’s role in supporting virtual and remote production workflows will continue to grow.
