Working at the limits of broadcast technology, news providers are constantly stretching systems to deliver their story first. Discover how the winners operate and quickly master the technology they value.
On October 27, 2020 The Federal Communications Commission issued an order to expand its captioning mandate for broadcasters to include audio description requirements for 40 designated market areas (DMAs) over the next four years. The move came after the Twenty-First Century Communications and Video Accessibility Act of 2010 (CVAA) directed stations in the top 60 DMAs to provide what it calls “described programming.”
IP networks are delivering outstanding success for broadcasters, both in terms of scalable functionality and flexibility. And the recent NMOS suite of specifications is improving integration and control, with IS-06 and IS-07 accelerating the process.
SDI and IP differ fundamentally in their approach to data transport as SDI is circuit switched and IP is packet switched. This provides interesting challenges for us as we start to consider what it means to route IP signals.
IP networks provide us with untold flexibility, but this flexibility presents us with interesting challenges of control. Developments in SDN (software defined networks) are leading the way through the separation of the control and data plane. And as we discover more of what SDN means, we soon realize that broadcasters are closer than they may think in achieving its operation.
Timing accuracy has been a fundamental component of broadcast infrastructures for as long as we’ve transmitted television pictures and sound. The time invariant nature of frame sampling still requires us to provide timing references with sub microsecond accuracy.
For content providers (studios, content owners, content aggregators, or other content licensors) and their licensees (affiliates) operating in a multiplatform world - and pirates looking to obtain illegal access to the most popular content - it’s an unrelenting game of cat and mouse. While the internet has provided a cost-effective and easy way to deliver content to consumers, it also opens up new vulnerabilities that content pirates are eager to expose.
The industry experienced futureshock head-on in 2020. The impact will take a long time to unwind but it’s already clear that some changes will be profound and not all of them bad. These changes include remote workflow permanency, virtual production shifts from exotic to routine and genuine efforts to save the planet. Here’s hoping.
With viewers demanding to watch what they want, where they want, and how they want, it’s not surprising we’re seeing an unprecedented growth in broadcaster OTT requirements. However, the change in delivery format from traditional broadcasting is providing us with some interesting challenges.
