What is a video wall controller?
To understand the video wall controller, first you need to know the video wall. Literally, a video wall is a wall or an area where content can be displayed. The common video walls on the market now consist of LCD splicing screens/LED/DLP. Video wall solutions have been well received in government, energy, finance, real estate and other industries.
Why do you need a video wall?
Display systems are not normally bigger than 70 to 80 inches diagonally. However, video wall can be scaled to much larger sizes than another display unit. Video wall with standard form factor can be made as large as 20 feet, which only a few rooms can handle. These video walls can also be incorporated as microtiles which operate on the same architecture as a standard video wall. Incredible size options make video walls the best options for city centres, airports and sports stadiums.
What is a video wall controller?
The video wall controller is a device that can manage the aforementioned video wall (output) and all connected signal sources (input).Hardware for visualizing various information and data.
The video wall controller is used to manage and control the display and operation of the video wall system. It can be operated according to the needs of customers and the display requirements of the video wall （It is widely used in monitoring centers, conference rooms, advertising displays, stage performances and other places that require large-screen high-definition display and data visualization.）
Video wall controllers are roughly divided into two categories, distributed architecture (AV OVER IP) and traditional hardware-based centralized controllers.
(FPGA Centralized controllers)
When we have multiple different signal sources or different images displayed on the same display or multiple display groups. We can use the video wall controller to combine, split, switch, zoom and other processing signals to meet the display requirements of the video wall.
As shown in the picture, on the left are different signal input sources input to the VKL video wall controller, and then transcoded and decoded by the controller. output to each display. We can connect PC to control via LAN, or use WiFi to control.
Video wall controllers usually connect multiple input devices (PC, player, Server) and centrally manage content.
Using the video wall controller device, you can zoom the image on the entire video wall, or spread multiple images on the entire video wall, or even stretch/roam/signal cropping...
