Sitting at home watching the Olympics 400m Women’s hurdles final live on NBC’s 4K HDR channel, home audiences were captivated by the sweat and effort displayed on screen with immersive sound of the runners’ feet hitting the track. Viewers thousands of miles away could be excused for thinking they had the best seat in the Japan National Stadium. The live 4K HDR broadcast of NBC’s primetime show throughout the Games were an extrasensory experience unlike any previous Olympics telecasts.
Playout automation has been enabling fewer people to control more channels for decades but we’re not quite at the point where human interaction can be eliminated altogether. Since most linear broadcasters will either move to a software-based deployment for their channels themselves or give them to a service provider that carries out that transformation for them, The Broadcast Bridge assesses the benefits and the challenges in so doing. Part II examines the crucial role of IP and the workflows and skillsets needed to operate such infrastructure.
In the last two articles in this series we looked at why we need to monitor in OTT. Then, through analysing a typical OTT distribution chain, we sought to understand where the technical points of demarcation and challenges arise. In this concluding article, we look at what and where to monitor in a multi-service-provider OTT delivery system.
In the previous article in this series, “Understanding OTT Systems”, we looked at the fundamental differences between unidirectional broadcast and OTT delivery. We investigated the complexity of OTT delivery and observed an insight into the multi-service provider silo culture. In this article we fully analyze a typical OTT delivery channel to understand why we need monitoring.
In this series of articles, we investigate OTT distribution networks to better understand the unique challenges ahead and how to solve them. Unlike traditional RF broadcast and cable platform delivery networks, OTT comprises of many systems operated by different companies to deliver programs to viewers, and it’s these potential silos that are the root of the challenges OTT faces.
Saving dollars is one of the reasons broadcasters are moving to IP. Network speeds have now reached a level where real-time video and audio distribution is a realistic option.
Taking this technology to another level, Rohde and Schwarz demonstrate in this eBook how to reduce costs even further and provide contribution and distribution over the internet.
In part-1 of this series, Challenges, we introduced the basic concepts of the technology behind live OTT delivery. In this article, we dig deeper to help broadcast engineers and technical managers understand the intricacies of HTTP and IP technology, so they will be able to design and support OTT systems more effectively.
