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.
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?
