University of Hertfordshire

The University of Hertfordshire in Hatfield recently rose to a record high ranking of 21st in the UK and perhaps almost as significantly has achieved the best employment rates for graduates in the East of England region, outscoring all Russell Group universities (including Oxford and Cambridge) within this criteria. These achievements reflect a highly progressive establishment which is an exemplar of scientific and technological innovation.

University of Herts Introduction
University of Herts Quote

"The Wyrestorm network HD offers a superb, flexible solution which is incredibly simple to install and operate."

1. The Objective

With AV systems now a fundamental part of educational processes, the University consulted with audio-visual consultants Hewshott International to address this vital component of the new facility. The University wished to be able distribute any video source to any screen within the building, whether this be simply within one teaching lab, from one lab to another or indeed to displays outside the immediate teaching environments. 

POLAR recommended a Wyrestorm solution that would enable the distribution of 59 different sources to 90 display units. Given the area and topography to be covered, much careful planning was required to ensure the system was straightforward, scaleable and could be easily added to or restructured. In the initial stages of the project POLAR, in conjunction with its partners, staged a demonstration of the technology and offered the university a workshop session to better explain the simplicity behind setting up the solution from scratch.

2. Our Approach

59 x Wyrestorm NHD-IPTX transmitters were installed to take HDMI signals from the source units and encode them to JPEG2000 data streams. These streams are transmitted through a Cat 6 infrastructure through a number of Juniper 1G switches. The switches effectively behave as a video matrix to distribute the streams via further Cat 6 to 90 x Wyrestorm NHD-IPRX receivers assigned to each of the display units. Visually lossless, the streams are decoded by the receivers back to HDMI for output to the display. The stream traffic is controlled by a NHD-IP-CTL controller receiving IP commands from a Crestron control system within each lab. Compression and decompression involved in the JPEG2000 technology does not inevitably degrade the image - something that was held under close scrutiny by the critical eye of UH’s Adam Harvey whose “image quality is king” mantra set a benchmark for the project and which he considered critical to its success.

3. Outcomes

Adam Harvey, Solution Architect AV & Digital Media, University of Hertfordshire:

"Overall, we are very pleased with the outcome. I think that we’ve been able to deliver an extremely flexible and futureproofed solution for the Science Building in an innovative way. There were some learning curves for UH and Reflex during the installation but we were very happy that Darren and Stuart from POLAR and James Meredith from Wyrestorm were always available to offer support and advice to the whole project team and attend the site when required. This is a very different way to deliver a whole-building AV solution than our usual systems but working alongside extremely professional people with vast technical knowledge, made this project run very smoothly considering its size."
