Sector Showcase Room control

With increasing amounts of technology used throughout buildings, management and control of a system from a single point is paramount to the user experience. James McGrath reports on five fully controlled environments in in the education, medical and leisure sectors

AMX offers decisive control at Medical Centre Alkmaar

The quality of decision-making can literally be a matter of life and death in hospitals. The Medical Centre Alkmaar (MCA), located in the northern part of the Netherlands, has a conference room replete with audiovisual, videoconferencing and medical visualisation technology. It’s used by medical staff from the Radiology, Oncology, Haematology and Pathology departments to enhance the hospital’s treatment

of chronic illnesses and provision of top- level emergency services and advanced clinical procedures.

The high-spec conference room, which enables information analysis and collaboration of the highest level, is controlled via an AMX control solution and single management interface. This allows staff to manage the numerous disparate systems all from one panel, and ensures interoperability between the hospital’s medical systems and content arriving from AV sources such as the hospital’s Picture Archiving and Communications Systems (PACS).

An AMX Optima DVI 8 x 8 matrix switcher controls high-resolution DVI signals by routing and distributing them around the

room. Medical professionals can switch between sources via a 10in Modero NXT- CV10 Tabletop Touch Panel. To display medical and diagnostic images, the room has several 70in NEC HD LCD screens, which are accompanied by two projectiondesign F22 Medical WUXGA projectors.

The 8 x 8 Optima matrix supports resolutions up to 1920 x 1200 at 60Hz and is preloaded with the most common EDID settings. It also includes features that simplify DVI integration, such as cable equalisation, signal reclocking and a new EDID Programmer.

This set-up means that important decisions do not have to wait until doctors can travel to the hospital. Medical staff in the multi-faculty room can hold discussions and meetings with doctors who have access to videoconferencing equipment at other locations. At the press of a single touchscreen button, the videoconference preset will switch on the screens and system, adjust the lights to a predetermined level and select the appropriate sound source. (This is one of numerous one-touch options programmed into the system.) An NI-3100

Cue handles virtual lectures in business school

Latvia’s Riga Business School (RBS) has always been at the forefront of the adoption of technology in its lecture theatres. The management education institution, located within Riga Technical University (RTU), believes that the support afforded by technology has, over the years, contributed to the success of some 900 MBA graduates. In 2011 the completion of an interactive telepresence auditorium took the facility’s teaching capabilities to a new, virtual level. The space has been equipped to ensure that communication between students and lecturers – either of whom may be in remote locations – is as natural as possible, and the system is straightforward to use. For local use, the system had to feature video projection, a sound system, an interactive whiteboard for collaboration, and a lecture-capture system with automatic instructor tracking. For remote instruction and student/lecturer interaction, the auditorium additionally required videoconferencing, speech capture from each individual seat, automatic voice sensing, and lecture recording for online streaming. In addition, for the purpose of remote participant involvement, two-way or multipoint HD videoconferencing was a requirement, as was automatic instructor tracking and lecture capture and streaming.

In the auditorium, three Epson EB-G5750W Full HD projectors support videoconferencing or presentation. For local recording, three PrecisionHD 1080p cameras are connected to a Tandberg C60 codec via an Extron DXP 88 HDMI matrix switcher.

Four chained Biamp Nexia VC DSP units process audio from no fewer than 30 beyerdynamic Classis BM 32 table microphones, providing speech equalisation, auto mixing and echo cancelling, as well as signalling to and from a Cue ipCue Delta control processor. Real Sound Lab equalisers are used in conjunction with the company’s CONEQ solution to correct linear distortion.

Rounding off the lecture capture and telepresence solution are the multifunctional push buttons embedded into desks in front of each microphone unit. These feature bi-colour indication and are used to manage camera and/or microphone operation, register attendance, or for voting.

To control this array of technology is a Cue control system, comprising an ipCue Delta control processor, one built-in 12in touchCue-12-B touchpanel and a touchCue- 12 mobile tabletop panel.

The ipCue-delta monitors the

microphones and sends information to the automated PTZ camera control. This ensures the student speaking is caught on camera; a remote lecturer receives the appropriate audio and video, and can then reply, as if speaking directly to the student. Both touchpanels handle presentation, videoconferencing, audio and lighting control in the auditorium, enabling faculty members to change audio or video sources at the touch of a button. Individual PINs have been assigned to staff so that the user

interface is accessible as either a basic user, an advanced user or an administrator, with language preference – Latvian, Russian or English – also changeable any time. This predetermined setup helps avoid complications and minimises support staff involvement, as each lecturer group has a tailored programme of system management. When support staff are required to operate the system, the mobile tabletop panel is used, out of sight of lecture participants.

NetLinx Integrated Controller is responsible for managing and controlling components including audio- and videoconferencing, as well as projectors, DVD and Blu-ray players, lights, thermostats and other electronic equipment found in larger areas. The NI-3100 can support future expansion of the system through optional device additions and control capabilities. It also features an ultra-fast processor and

64MB of onboard RAM.

The simplicity of the NXT-CV10 touchpanel, together with the level of control provided by both the 3100 NetLinx Integrated Controller and the Optima DVI 8 x 8 matrix switcher, gives hospital staff access to the information and the expertise that they need to make informed medical decisions.
