High Definition Linux

Acrodyne Industries is embedding Linux in their newest HDTV transmittors.

What's the best looking Linux you've ever seen? Well, if you're among the shrinking number of people who haven't been stunned by HDTV, you may have already seen it. Acrodyne Industries, the television transmitter division of Sinclair Broadcasting, has a history of industry firsts, and the latest is embedding Linux in their newest transmitters.

Andrew Domonkos, principal systems software engineer with AI, says:

We are the first in our industry to introduce a television transmitter system using Linux as its operating system. Our-top-of-the-line HDTV transmitter series, the Quantum, uses an industrial PC running Red Hat Linux in a network server configuration. We chose Linux for both its reliability as well as its networking potential. Running anything else would be unacceptable; when a TV broadcaster goes off the air due to a system controller problem, the loss in revenue can be tremendous.

A paper by Acrodyne's Marc Polovick explains:

Linux (which is internet synonymous) is a UNIX-based OS and provided a valued starting point to this requirement. It was the intent of the Quantum designers to use UNIX as it was designed to be used, in a distributed processing "server/client" environment, a real-time/object-oriented data driven system architecture. A user-friendly GUI is provided and is displayed through one large LCD display device. This intuitive graphics-based interface has been designed to be mimicked and to provide secure "remote anywhere" monitoring capabilities that are network accessible in almost every network environment.

At the receiving end, Linux has become a common operating system in set-top boxes as well. In fact, National Semiconductor created Linux4.TV, "Where open-source Linux meets interactive television"--for engineers working on products that use the company's Geode SC1200 integrated processor and SP1SC10 development platform.

More proof that Linux just keeps looking better.

One Click, Universal Protection: Implementing Centralized Security Policies on Linux Systems

As Linux continues to play an ever increasing role in corporate data centers and institutions, ensuring the integrity and protection of these systems must be a priority. With 60% of the world's websites and an increasing share of organization's mission-critical workloads running on Linux, failing to stop malware and other advanced threats on Linux can increasingly impact an organization's reputation and bottom line.

Linux Backup and Recovery Webinar

Most companies incorporate backup procedures for critical data, which can be restored quickly if a loss occurs. However, fewer companies are prepared for catastrophic system failures, in which they lose all data, the entire operating system, applications, settings, patches and more, reducing their system(s) to “bare metal.” After all, before data can be restored to a system, there must be a system to restore it to.

In this one hour webinar, learn how to enhance your existing backup strategies for better disaster recovery preparedness using Storix System Backup Administrator (SBAdmin), a highly flexible bare-metal recovery solution for UNIX and Linux systems.
