design. It designed a video wall that pops out of the studio wall, creating a 3D effect, and the shape of the units means it is able to create a wall that isn’t rectangular in shape.” Following on from the NOS
installation, Eyevis is in talks with UK broadcasters about installing Omnishapes walls, although no deals have yet been signed.

When Sky News Arabia was setting up its studio in the UAE capital Abu Dhabi, it enlisted Shooting Partners to provide a display system. The Middlesex-based firm plumped for a 7 x 2 wall of Barco OVL 708 cubes and a Christie Vista Spyder X20 hardware-based video processor. Christie EMEA Vista System Prod-

unit, which is LED illuminated, while the units have an adjustable colour temperature of between 3,200 and 5,200 Kelvin. The units, which are 48cm wide and 55cm deep, have an 0.8mm bezel and come in a range of shapes: 4:3, five-sided polygon, hexa- gon, or customer-specific designs. The modular design means users
can replace individual units without adjusting the entire wall, says Eyevis product developer Hans-Günther Nusseck. “The shapes allowed NOS to be creative with its screen

ucts sales consultant Nick Wheeler says part of the 24-hour free-to-air news channel’s brief was for the pro- duction team to be able to display any sources, from VTR to OB, on the wall using key frame effects, and with low latency. It also needed a system that didn’t take up a lot of rack space and could fit easily into the broad- caster’s control room. “It wanted to run the processor
using a Kayenne vision mixer, rather than a separate console, so we installed a bus translator from the vision mixer to the X20,” Wheeler says. Creative head for Sky News Arabia
Roland West adds: “When we set out to create Sky News Arabia, the key requirements for delivering a successful graphics package were quality of finish, ease of use, unity of platform and a breadth of graphic presentation.” Sky News Arabia uses a Vizrt system
to deliver its live news graphics, with a screen furniture of multiple tick- ers, side panels, maps and breaking
The public area on the ground floor of the University of Salford’s MediaCityUK base is dominated by a digital interactive area that has a presentation screen and 10 touch tables. The central feature is a high-resolution display wall made up from 120 Christie MicroTiles, which can display images of 9600 x 3840 resolution. The MicroTiles wall has initially been installed as a 15 x 8 array, but the tiles can be rearranged to 12 x 10 or 20 x 6, depending on the project.

on the wall, whether it is an animated background from Vizrt engines or a camera feed, are fed into one of the 16 inputs of the X20. Any or all of those inputs can then be placed on the wall for the presenter to use. The Spyder X20 has a processing
latency of about 1.5 frames for inter- laced sources. Latency, Wheeler says, is a key consideration when a pre- senter is standing in front of a video wall, particularly when they are talk- ing to a colleague who may be in another country. “There are no lip- sync problems when filming a wide shot of the presenter and the win- dow in which his or her colleague is shown.”
