Video Wall Controllers
Video walls have now become a common sight where they combine a series of tiled displays into a large, single display surface. Video wall displays are ideal for government, military, energy, utilities, traffic and broadcast control room video walls that require 24x7 reliability and brilliant life-like images. A video wall controller is made up of a video wall server and video wall software. The video feeds are controlled and relayed by the video wall server while the software allows the technician to decide how the feeds are displayed
Video wall controllers are highly specialized visualization systems consisting of a single system built with a large number of graphics processors. They are capable of both rendering and capturing video, in some cases allowing hundreds of video feeds to be built into a single system.
Video walls are a visually stunning method of advertising, providing both information and entertainment to the customers. They are adaptable used in many indoor and outdoor business environments due to their enormous flexibility. The screens can be updated dynamically via the Internet or using a remote control and/or direct cable connection. They can even be interactive. The olden type of video walls required extensive set-up and utilized a great deal of noisy and expensive hardware, however the video wall controller changes all this.
Video wall controllers allow the user to manage image, graphics or data that is being displayed on any video wall. When a video wall controller is used to manage a video wall display, issues like which video feeds or sources will be used, where the video will be displayed, whether the image will occupy the entire video wall or will it be an amalgamated data display are all nonexistent.
With changing technologies, video wall controllers have also evolved. A simple piece of Windows compatible software, which even can be used over a network, is only needed. No matter how complex the system is; versatility of the video wall controllers and its input-output designs enable the users to take control of video walls.
It is custom built for the specific requirements of control room environments, and combines both hardware and software in the ultimate display. It is designed to be a part of your complete control room and video wall solution.
The video wall controller brings high-resolution multi-screen images easily and quickly, perfect for surveillance, traffic monitoring, advertising, remote conferencing and many other applications and across many displays.
Video wall controllers are used in most number of video wall applications such as control rooms, network operation centers, military and civilian surveillance, video conference rooms, corporate communications / board rooms, residential, digital signage and digital out of home applications and any such application requiring both video input and output making its uses endless. They are highly scalable allowing a great many number of feeds and devices to be incorporated into a pretty huge single system. Connected into a single system which in turn makes a highly dynamic, multipurpose video wall possible. Video inputs transform a video wall into a highly dynamic, multi-purpose system.
As video wall controllers use highly specialized graphics hardware designed to accommodate high rates of video input and output, they do not excel at 3D rendering. Although some 3D rendering may be possible via video wall controllers, other HD-rendering approaches can achieve much higher 3D performance.
With changing technologies, video wall controllers have also evolved. Rather than just displaying standard videos, digital formats of videos like MPEG, Shockwave Flash, Real video and QuickTime are now under the ambit of video wall controllers. Bulky and extremely expensive customizable programming solutions are passé. A simple piece of Windows compatible software, which even can be used over a network, is only needed. No matter how complex the system is; versatility of the video wall controllers and its input-output designs enable the users to take control of video walls.
The video wall controller is the central nervous system of a control room video wall solution. Network-based video wall controller servers and software offer the reliability, performance, compatibility and versatility needed in today's 24x7 control room environments. High resolution graphics and video from multiple sources can be displayed any size, any where, any time, across the entire display wall. A simple technology comparison reveals that the network based video wall controller is far more versatile and easier to use than the matrix switcher or image processor solutions.
