Five Types of Video Walls for Control Rooms

The majority of control rooms have some sort of large display wall, whether a single or multiple screens, tiles, or projectors.  This helps to create large-scale visualisation and a common operating picture for everyone in the control room.

There are several ways to implement video walls for control rooms depending on the level of complexity and budget.  The purpose of this post is a focus on the video processing aspects of the video wall, not on the display technologies.  To help put different options in perspective, the following descriptions are provided for comparison.

Basic Video Walls

basic-video-wallMonitor Wall
The Monitor Wall is the simplest form of video wall as it is just a collection of individual monitors.  Each piece of content is limited to a single screen and cannot be scaled across multiple screens.  A monitor wall can be driven by dedicated sources, or it could be front-ended with a matrix switch (AV or KVM) to switch content on the screens.  Alternatively, an IP-based matrix can provide significant scale for switching the number of potential inputs in a distributed manner while avoiding a centralised matrix chassis.

A Quad-Screen Wall is a 2×2 video wall on which a single input is scaled across all four monitors.  The wall could be front-ended with a matrix switch (AV or KVM) or even just a small presentation switcher if the number of inputs is limited.  Alternatively, an IP-based matrix can provide significant scale for switching the number of potential inputs in a distributed manner while avoiding a centralised matrix chassis.

Intermediate Video Walls

A Multi-Window Video Wall can support content that scales across multiple screens, can be larger than a 2×2, but the content windows are limited to screen sizes.   For example, with a 4×4 wall, up to four 2×2 windows could be displayed, or a 3×3 window with 7 additional single screen windows, or the entire 4×4 could be a single window.  Or, there could be two 2×2 windows with eight additional single screen windows.  An IP-based matrix solution is a very easy and low cost way to implement this type of video wall.

Multi-View Video Wall
A Multi-View Video Wall is driven by a multi-viewer, which is a video processor that provides a limited number of pre-designed layouts for a single output.  Options typically range from 4-8 windows.  A multi-viewer can be used when the number of windows and scalability of a larger video wall processor is not required.  A multi-viewer can also be coupled with a projector or quad-screen wall processor to increase the viewing size.

Advanced Video Wall

radian-video-wallAn Advanced Video Wall is one that supports a large number of screens of different form factors (e.g. 2×2, 3×2, 6×3, etc.) and offers a canvas-type display interface on which numerous content windows can be dynamically moved or resized.  Advanced video wall processors support dozens of screens and numerous types of video inputs. The processor can also support native decoding of IP streams for displaying large numbers of streams from IP-based security cameras, and can also support encoding of video sources for sharing to additional sites or users.  Advance wall processors can typically drive more than one video wall from the same system.

Below is a summary of several features and capabilities of the different type of video wall processors used in control rooms.

The digital signage industry is growing big with video wall installations being used in retail stores, hospitality environments, sports venues, emergency operation centres, power plants, traffic management centres and more. We’re living in an age where monitoring business-critical or even life-critical operations 24/7 is a must. Operators need to rely on dependable visualisation, often in a networked setup, for their decision making. Whilst choosing the right video wall processor depends on distinct factors that rely on different factors like the level of complexity and budget, it is unquestionable that large-scale visualisation is necessary for critical monitoring environments, making it easier for information sharing, faster communication, and optimal performance of control rooms.

Oil & Gas Networking and Control Room Solutions

Industrial connectivity and KVM control room solutions for upstream, midstream, and downstream environments.

As the oil and gas industry continues to grow, more and more well sites, pumping stations, pipelines, processing plants, and refineries are being built. Along the entire route, safe, reliable networking and industrial automation are critical to smooth operations, efficiency, and productivity.

In 2014, the United States produced 9.2 million barrels of crude oil a day. The U.S. is now the largest producer of oil and gas, overtaking Saudi Arabia and Russia due to production from the Marcellus Shale. However, reservoirs of oil are becoming more difficult to access and increasingly less productive. To keep pace global consumptions, oil companies must constantly look for new sources of petroleum, as well as improve the production of existing wells.

Digital KVM Control and Monitoring Solutions for the Energy Industry: Automation, processes, and workflow

Black Box is committed to helping our customers succeed as they transition to the digital media environment. We help clients in the energy industry design and deploy mission-critical solutions.

In drilling operations, KVM systems provide high-quality and instant access to video and control signals from multiple sources to multiple users. In oil and gas exploration, rapid access to graphical data and processes throughout a seismic survey and the ability to respond quickly to status changes are crucial for safe and efficient operation. Remote monitoring solutions in control rooms provide users with better overview, quicker access to data, and failover connectivity. With KVM solutions, users can switch and extend real-time HD video and USB HID over LAN/WAN for remote monitoring.
