Markets: Command and Control
Electrosonic worked with Tyco Fire and Security on Derbyshire Constabulary’s purpose-built control centre
believes,“the association with their brand values and the simplicity of ordering. But manufacturers like Matrox also have strong brand promise and reputation. The Mura videowall controller boards are standards-based so they allow integrators to select the most appropriate platform to configure best-of-breed solutions and provide simplicity of ordering. Some screen vendors have sought to incorporate Matrox videowall solutions to deliver the highest quality performance to match that of their displays.” And as Nick Mawer,
marketing manager at Kramer Electronics points out, it’s not just about display wall controllers. “Multiviewers have their place in smaller systems where a single display is being used,” he points out. “Using technology first used in broadcast television galleries, Sierra Video manufactures a range of multiviewers that can allow up to 64 images over two displays. Those have been used in a number of emergency services command and control installations.” The choices range from the
simplicity and security of a single vendor solution with its benefits in terms of tight integration between screen and controller and ease of ordering and support, and third-party offerings that may offer more in terms of functionality and performance. There is no less wide a range of options when it comes to a discussion of whether the ideal videowall controller should be based on open standards such as Windows/Intel platforms, or whether users’ interests are better served by proprietary architectures. “All our display wall
controllers and software servers use industry server components,” notes Schmidt. “The decisive component in the display wall controllers is the graphic cards. The proprietary component in our controllers is the design of the

system and the software and the drivers that run the system. Our wall management software – eyecon – is a proprietary development.” Christie offers both. “Our TVC series is based on HP servers, using Intel Xeon processors and the Windows operating system,” says Griffiths. “They are essentially COTS [commercial off-the-shelf] solutions, using COTS components – although we write the drivers ourselves.” “Our Spyder, on the other hand, is 100% Christie- developed and built, with a hard-wired bus structure for higher levels of performance and reliability. It’s a purpose- built image processor.” Barco too offers a range of options. “Barco’s Transform N
can be deployed as a software- only solution, running on COTS PC hardware and standard Windows operating systems,” says Bussens. “We also offer PC platform hardware systems that are optimised for use in a 24/7 control room environment and that are fully validated for compatibility and performance with our software. Beyond this, we can provide dedicated hardware components such as rackmount, full frame-rate dual-link DVI encoders when high performance and/or high density encoding and/or high availability is required.” For RGB Spectrum, the
optimum solution is clear. “We believe that an embedded systems approach, adopting open, industry standards, is superior to the PC/Windows/ software-based approach for several reasons,” argues Spronk. “The level of performance is far superior, as you can design a solution that provides dedicated resources along the parallel processing path for a given input, allowing you, for example, to show 30 HD sources in real time. This is the single most important benefit. Using embedded systems also reduces risk of typical PC vulnerabilities
CASE STUDY
Swiss public water authority installs eyevis solution
Wasserversorgung Zurich is responsible for the quality and supply of water to the Swiss city and 67 neighbouring communities, delivered via a 1,500km pipeline network. At its newly refurbished and
re-equipped control centre, among the most important tasks of the operators are the management of water production and distribution as well as supply assurance following service disruptions such as pipe ruptures. The control centre now
features a display wall from eyevis, installed by integrator WEY. It comprises an 8 x 2 array of 50in DLP (LED-illuminated) rear-projection cubes. The videowall can be controlled from any workplace using eyevis’s Netpix 4800 display wall controller, which provides all the necessary signal inputs. In combination with eyecon wall management software, all computer systems, applications and signals can be projected in any scale on any cube. This
allows complete flexibility, WEY complemented the
solution with additional systems, including an Auto Color Tracking feature that enables colour and contrast adjustments to harmonise the pictures across the wall, and a Central Interface Controller, which allows event-driven alarms to be automatically projected onto the large screen displays, simplifying the monitoring of all the systems. The solution was deliberately
designed in an open manner so that new requirements, functions and media can be quickly and easily integrated – and, in fact, even since its recent installation, new signals have been added.
