In today's world, it is becoming increasingly important to be able to protect classified data-at-rest with encryption for critical data, such as that captured and stored during airborne intelligence, surveillance, and reconnaissance (ISR) missions. For some programs with limited budgets and schedule, using National Security Agency (NSA)-approved Type 1 encryption, the highest level of data protection, may prove impractical due to the high cost - typically several millions of dollars for a new development - and long process - typically two to three years that it takes to reach full certification. The cost and schedule required to deliver Type 1 encrypted hardware has meant that industry's ability to provide robust data protection has lagged far behind the demand.
Video-centric systems are used to capture specific video data and switch the video data to displays for viewing, and store for later analysis. The basic video-centric system consists of multiple video sensors (typically cameras), multiple operator displays and storage to capture the video. A video-centric system may be stationary or mobile. This paper gives a brief introduction to stationary systems with further focus on mobile applications.
The key attributes of a PLS, such as the Curtiss-Wright GLX4000, clearly point to its flexibility. Since it is a digital device, network connections and configuration can be done through software, via a Command Line Interface (CLI) or Graphical User Interface (GUI), remotely if necessary. The non-blocking, digital backplane permits any configuration, with any input connected to any output. Being network transparent means a PLS acts as a pass-through, uninvolved in the protocol. The fact that a PLS is protocol agnostic allows support for any serial digital protocol, standard and non-standard. The flexible nature of a PLS lends itself to many military and commercial applications. In the case of the GLX4000, one of its many advantages is the ability to act as a media converter.
