In the last article we looked at why we need security in a broadcast network. In this article we continue the theme of looking at a network from a broadcast engineers’ point of view so they can better communicate with the IT department, and look at how IT engineers implement network security.
The forthcoming transition to ATSC 3.0 will usher in the need for higher data rates and more channel capacity in the over-the-air architecture. Broadcasters will apply their experience as “Bit Managers” in the studio infrastructure to the RF operation, with the knowledge that more power leads to higher quality of service (QoS).
Television broadcasters have long relied on compelling content to maintain and increase audience loyalty in an increasingly aggressive marketplace. But with viewers now spoiled for choice, will strong content alone be enough to survive in the 21st Century? If not content, what other tools can broadcasters employ to actively engage audiences?
While international broadcasters covering this years Summer Olympic Games in Rio mostly worked in HD, 1920x1080, NBC used a fair bit of Ultra-HD equipment to cover specific events, such as the opening and closing ceremonies. The 4X HD resolution provided visual excitement to the events, even in slow motion.
KVM is more important now for broadcast-IP systems than it ever has been. As manufacturers turn to server based architectures private cloud installations have become more mainstream, requiring us to configure systems through traditional server control inputs, that is keyboard, video and mouse.
Many seats may have been empty for some of the events at the Rio Olympic Games but online audiences as expected scaled new heights. Streaming traffic for the games has obliterated records set by previous events, according to CDN giant Akamai, which delivered more video data in the first eight days of Rio than it did for all 34 days of the 2012 London and the Sochi winter games combined.
As OTT consumption continues to rise, broadcasters and content distributors see the cloud as a way to respond to an insatiable demand for new channels. Likewise, the cloud seems to be a good solution to disaster recovery (DR). Cynics, however, are quick to note that the cloud, especially a public cloud, is unproven and unprepared both in terms of security and the QoS required by broadcasters.

The Duchess of Windsor, the American wife of the man who was previously England’s King Edward VIII, famously said: “You can never be too rich or too thin”. If she’d lived in the 21st century, she might have added: “… or have too much bandwidth”.
