Hyper definition: 4K screens in DOOH

Display products such as PsCo’s hyperwall have put digital signage companies at the fore of 4K development

4K is undoubtedly expanding. Video production houses welcome the format and, even if they often have to use down-converters from 4K to HD, the image quality is still better than what can be captured via HD. Most video camera manufacturers have already launched 4K cameras and creative advertising agencies are adopting it in an attempt to future-proof their work.

Sony’s latest professional monitors, the PVM-A250, 25″ (60cm) and PVM-A170, 17″ (43cm), have been designed to be 4K ready. Using organic LED (OLED), these lightweight, slim screens have high colour accuracy, contrast and picture quality.

“Higher resolution content creation – 4K and beyond – requires monitors with larger screen sizes for accurate colour evaluation on site,” says Daniel Dubreuil, senior product marketing manager for professional monitors at Sony Europe. “Yet bigger monitors are harder to carry and take up more space. These new models have the screen size needed for critical evaluation, with a thinner and lighter design that’s perfect for live broadcast and outdoor shooting. They even have a handle for easy carrying.”

Danish broadcast production start-up Nimb TV has recently unveiled Denmark’s smallest Ultra HD Outside Broadcast van. The unit is built around a number of Blackmagic Design’s raft of Ultra HD products, which includes the ATEM Production Studio 4K and Blackmagic Audio Monitor. Housed in a three-wheeler moped van, it can be positioned at the heart of any live production, not simply feature films. But it is not necessarily the broadcast market that is paving the way forward in 4K.

“The AV and digital signage markets are leading on Ultra HD, 4K adoption,” believes Patrick Hussey, senior communications manager for EMEA at Blackmagic. “Meanwhile, the broadcast industry is, for once, playing catch up.”

Stuart Holmes, chief executive at AV distributor PsCo, corroborates this: “In the professional AV world, 4K or Ultra HD is nothing new; it made huge waves at CES and is now one of the latest buzzwords in the consumer market. Consumer expectations of image quality are through the roof as they compare the fine detail they get on their tablets, smartphones and home TV sets to displays they come across daily in the out-of-home world.

“As experts in videowalls, targeting vertical markets such as broadcast, public sector, retail, rental and corporate, we understand 4K and, from a multi-display angle, we have been delivering videowalls with higher than 4K resolutions for a long time. Our focus has always been more on delivering according to the required display size, shape and pixel by pixel performance required for a specific environment.”

In the AV manufacturing sector, the projector industry leads the way on 4K, particularly for 3D applications. Some manufacturers are already claiming they use 8K, although most of the time that means two 4K projectors, which gives better definition, but not at 8K standard. 

In the residential market there are 55″ (140cm) 4K screens available for under £4,000, but in the professional market this quality of screen is not so widespread. Many LED manufacturers say that their HD screens are 4K ready, they just need the content to match. That said, there are plenty of HD DOOH screens already on the streets and, if the image is already fit for purpose, then why change them?

French creative company MovingDesign, which designed the amazing 4Temps mall in Paris, says that its clients are not worried about definition as long as it looks good, while Monster Media has made similar noises concerning 4K. However, BrightSign’s XD line software and firmware upgrade to support and upscale into 4K would indicate that the format is coming to DOOH. The company’s BrightAuthor 3.7 software and its companion 4.7 firmware XD can upscale 1080p video content to 4K and offers enhanced IP streaming and some very useful HTML5 support features. 4K-display manufacturer Seiki Digital recently demonstrated the impact of BrightSign’s XD video engine, paired with the new software features, at the IFA trade show in Berlin.

4K is a technology that is relevant to large videowall displays, rather than close-up screens. For screens that are used for interaction or large displays, such as roadside billboards, 4K is irrelevant. In cases where flat-panel displays are used to create large videowalls, the better the definition, the more eye-catching and effective the signage will be, so expect to see more 4K making its way into the DOOH market.

Rocking the Tobacco Dock: NEC Showcase preview

Now in its fifth year, the NEC Showcase 2013 will be held at East London’s Tobacco Dock, seeing NEC partners teaming up once again to demonstrate how their digital signage offerings work in different ecosystems. Visitors will reportedly be able to see more than 100 solutions represented through the two floors of the show across eleven applications zones: DOOH, retail, education, transport, 3D and leisure, 3D cinema, media, healthcare, control rooms, corporate communications and the NEC innovation zone.

Since its conception, the showcase has focused on providing end users with a tangible example of what it possible in a real-world situation, and an opportunity to talk directly with manufacturers and system integrators in each vertical market.



“The showcase is a unique event; where else can you see more than 50 different AV and IT vendors working together to show complete solutions?” asks Simon Jackson, vice-president at NEC Display Solutions. “We already have 600 people registered to visit.”


NEC itself is using its event as a launchpad for an 80″ (203cm) screen in its entry-level E series, plus the new P series 70″ (178cm) display with NFC and NEC NOC, a remote service network operating centre. Also new this year is a sensor-driven signage offering, the NEC Leaf Engine, co-developed with NEC Laboratories in Heidelberg.


“We’ve added a couple of NEC zones so we can show off our new technology but the really exciting zones are where the collaboration takes place,” enthuses Jackson. “Look out for retail and 3D – they should be fun.”



Ultra or 4K will feature heavily at the showcase, promised as a complete workflow. Content will be filmed live, edited, exported and displayed around the event. This will be shown on 2×2 and 3×3 video walls and a new high-end laser projector. What content? Watch out for the dancing girls!


Welcoming visitors at the entrance hall with a projection-mapped tunnel will be 7th Sense. Using its Delta media server solution it will show fully uncompressed 4K content on the NEC 4K projector. Richard Brown, principal engineer at 7th Sense, comments: “This is our first showcase and it provides us with an opportunity to demo our products as an integrated solution with NEC’s displays. The uncompressed nature of our video servers means that we can show them off at their best.”


Regular exhibitor PSCo will exhibit a videowall using five different screen formats. Driven by a Harris player, the wall will be arranged in a structure designed by Unicol and put together by PSCo’s engineers. It’s not all about what’s flashy, of course: Unicol is supporting NEC Displays throughout the show with its mounting solutions. There will be a number of coloured Axia lectern stands supporting 46″ (117cm) screens and Axia Titan stands built to carry 100″ (254cm) screens on different videowall arrays.


A newcomer at the showcase is Monster Media, whose managing director Liam Boyle is excited by what the event can offer. “Partnering with NEC is the perfect marriage of intelligent technology solutions and practiced content creation. One thing is to have the shiniest-looking kit on the block; another is to provide a valuable experience for the consumer.”



Exhibiting for the fourth time, White Space will be showing its latest version of 3D-Hub at the retail, education and events zones. 3D-Hub is an interactive media player with 3D content. Its features include rotating, exploding, animating, highlighting and labelling media. The 3D-Hub also works with regular 2D displays, which can be viewed in stereo 3D using Anaglyph or ColorCode 3D technology.



Also looking to take advantage of NEC’s outstretched arm to end users, IHSE will have a presence for the first time. IHSE is a manufacturer of advanced KVM and video extenders, which allow the remote location of auxiliary computer consoles at very long distances from device. Its KVM matrix switches enable different computers to be accessed through one or more consoles – all equipment vital to larger installations.


NEC is also giving visitors a voice. Attendees can submit questions upon registration or at the show via touchscreens, which will be displayed on screens across the show, offering food for thought. Running alongside the Showcase will be a conference organised by DailyDOOH, with ten speakers, in morning and afternoon blocks. And when the show’s done, don’t forget to prepare for a well-deserved drink reception after 4pm – which, some say, is when the business really begins.
