Internet delivery is playing an influential role in delivering programs. For viewers to have the best quality of experience, engineers and technologists must expand their understanding to appreciate the intricacies of computer networks & internet delivery.
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 2017, at that year’s VidTrans conference a regional gathering of members of the Video Services Forum (VSF), a new protocol for delivering audio and video over lossy IP networks (including the public Internet), was born. It was an idea that many had been skeptical of, since the open Internet brought with it all kinds of quality, security, latency and reliability issues.
High dynamic range and wide color gamut combined with 4K resolution and progressive frame rates have catapulted broadcast television to new levels of immersive experience for the viewer. As HDR and WCG are relatively new to television, we need to both understand their application and how we monitor them to enable us to surpass the levels of quality and immersive experience cinematographers demand.
Computer systems continue to dominate the landscape for broadcast innovation and the introduction of microservices is having a major impact on the way we think about software. This not only delivers improved productivity through more efficient workflow solutions for broadcasters, but also helps vendors to work more effectively to further improve the broadcaster experience.
OTT distribution is worlds apart from traditional unidirectional broadcasting in terms of its fundamental operation and viewing preferences.
The internet is a rapidly expanding collection of service providers, many in direct competition, transferring broadcaster video and audio streams alongside many other types of often conflicting data.
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.
