The US-based Advanced Television Systems Committee standardized three more components of ATSC 3.0, the next-generation television system expected to transform the ability of broadcasters to deliver mobile, interactivity and higher quality content.
Sometimes technical managers and engineers get caught up in technology as though it exists by itself. It is important to remember all new solutions must be installed and maintained by humans—and that may require new skills.
There are several solutions for optimizing the distribution of multiscreen video. One method is by controlling the origin server, with respect to packaging and encoding. Another is to use local caches installed in the networks of operators that are either handling an important part of the content provider’s traffic or experiencing difficulties delivering content to subscribers. A third approach involves using several different CDNs managed by a CDN selector.
The compression of high-quality video has traditionally been a compute-intensive operation requiring dedicated hardware. But the steady progression in computational power of commercial-off-the-shelf (COTS) equipment has enabled the gradual transition of some video processing operations to software-based environments. A software-based approach can offer significant flexibility and agility improvements over purpose-built hardware, but at a potential cost to video quality or density.
The cloud is one of the hot topics in the world of broadcast and media at the moment. Every vendor, it seems, is keen to offer a cloud solution, even if some are not always clear what it means, and where the benefits lie.
Broadcast television is undergoing a tectonic revolution from artisanal service provider to industrial scale producer. As the industry moves to its mature phase business owners require a highly efficient production line approach that is scalable, agile and cost predictable, allowing creative production teams to deliver better programming and viewer experiences.
IP is the enabling technology for this revolution, not the reason for it.
In the last article we looked at Firewalls and their place 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 use detection and prevention systems.
ATSC members approved the ATSC 3.0 Physical Layer Candidate Standard through balloting completed Wednesday.
