Your Position: Home - Conference System - What is the difference between video wall controller and video wall processor?
Video walls are a popular display technology used in a variety of settings, such as control rooms, retail stores, sports arenas, and corporate lobbies. A video wall consists of multiple displays arranged in a matrix, typically in a tiled fashion, to create a large, seamless image. Video walls can be used to display a single large image or multiple images, videos, and data sources simultaneously. To manage the complexity of displaying content on a video wall, specialized hardware and software components are required. Two essential components are the video wall processor and controller. In this article, we will discuss the differences between the video wall processor and controller.

A video wall processor is a hardware device that processes video signals and distributes them to multiple displays to create a large, seamless image. A video wall processor takes input from various sources, such as computers, cameras, media players, and video conferencing systems, and processes them to fit the configuration of the video wall. The processor takes into account the resolution, aspect ratio, and orientation of each display and adjusts the content accordingly.
The video wall processor can perform various image processing tasks, such as scaling, cropping, and de-interlacing. Scaling is the process of adjusting the resolution of the content to match the resolution of the display. Cropping is the process of removing a portion of the image that falls outside the display's boundaries. De-interlacing is the process of converting interlaced video signals into progressive video signals to eliminate flicker and improve the image quality.

The matrix adopts high-performance hardware design, perfectly supports a variety of high-definition digital / analog signal switching and processing, and supports two-way RS-232, two-way IR signal assigned switching function. It can also divide a completed image signal into several signals assigned to several different display unites, forming a large display screen to display dynamic images. It provides a one-stop solution for various industries to assign, switch and process a variety of video and control signals, which can be widely used in radio and television engineering, multimedia conference room, large-screen display engineering, television teaching, intelligent traffic management centers, command and control centers and other places.
A video wall controller is a hardware device that manages the video wall's display settings, such as brightness, contrast, color, and orientation. The controller is responsible for controlling the overall appearance of the video wall and ensuring that the image is uniform across all displays.
The video wall controller can also manage the content displayed on the video wall. It can switch between different sources, adjust the aspect ratio of the content, and configure the layout of the video wall. The controller can also add overlays, such as logos and text, to the content displayed on the video wall.
The video wall controller can be controlled through a variety of interfaces, such as a web-based interface, a remote control, or a physical control panel. The interface allows the user to configure the settings of the video wall, switch between sources, and manage the content displayed on the video wall.
The video wall processor and controller have different roles in managing a video wall. The processor is responsible for processing the content and adjusting it to fit the configuration of the video wall, while the controller is responsible for managing the display settings and content.
The video wall processor is typically a hardware device that is designed to handle the processing power required to manage the video wall's content. The processor can handle multiple video signals simultaneously and adjust the content to fit the display configuration. The video wall controller is typically a software application that runs on a separate computer or embedded system. The controller manages the settings of the video wall and communicates with the video wall processor to control the content displayed on the video wall.
The video wall processor and controller also differ in terms of their capabilities. The video wall processor can perform advanced image processing tasks, such as scaling, cropping, and de-interlacing, while the video wall controller focuses on managing the display settings and content.

Many companies and non-profit organizations that are considering implementing a video wall processor may still be unsure on whether it is required or whether it is worth the investment. This is a debate that some companies are still facing as multi-screen displays, known as video walls, are gaining popularity in a wider range of use cases from retail stores to hospitality, sports stadiums, classrooms, control rooms, lobby signage and corporate boardrooms.
While video wall technology may be complex, the reasoning for their widespread use is straightforward: video walls bring an easy solution to a big challenge: how to showcase information to both large and small audiences in a dynamic and adaptable manner. Video walls allow displaying a combination of content coming from multiple sources; they also provide an immersive experience which makes this information more impactful.
In addition to the screens themselves, video walls require advanced technology to make them dynamic and flexible to control what content is presented where, how, and when. This is where video wall processors come into play.
What is a Video Wall Processor or Video Wall Controller?
Briefly defined, a video wall processor (sometimes referred to as a video wall controller) is a piece of software (often installed on a hardware unit) that allows the management of content on multiple monitors in a multi-monitor display or video wall, as a single canvas. A video wall processor gives users the flexibility to visualize any piece of content across multiple screens or the entire video wall. It also allows for multiple pieces of content to be viewed on a single screen, a portion of the video wall or the entire wall, in any one of the unlimited possible combinations. Each display can be controlled individually or in groups, leading to a dynamic display solution that could be utilized to meet a wide range of display requirements while also delivering information effectively and compellingly. The number of monitors in a multi-monitor system might span from two to two hundred or more. The dimension and design of the video wall is determined by the requirements of the target audience.
What is the Purpose of a Video Wall Processor/Video Wall Controller?
Visualization solutions require some type of technology to control what a viewer can see. Consider an air traffic management centre: the more developed and intricate a framework is, the more robust the control system must be. To get the maximum benefit from a multi-monitor setup, maximizing performance, picture quality, security, and automation, a video wall controller is needed.
However, not all video wall controllers are created equally. The best ones offer increased usability, giving an organization’s audio-visual team or video wall operators, the tools they need to get the most out of the technology, right at their fingertips.
Benefits of Video Wall Processors (Video Wall Controllers)
Resolution is a popular concept. It all comes down to the number of pixels available, we call this “display real estate”: the more pixels on a screen, the higher the pixel density, the more accurate and better the quality of image you will get. It’s easy to see why video wall controllers are very efficient at producing an impressive visual impact based on this flawed concept. When you build a video wall with a series of high-definition screens, the resolution increases incrementally. A video wall can only effectively display high-resolution content without quality degradation if it benefits the support of a powerful digital signal processing unit, i.e. a video wall processor.
The connection and capacity to capture various sources on a single screen or projector is limited. They can interface with a limited number of devices and each screen can only display one specific source at a time. A video wall processor is needed to overcome these limitations so that a video wall can simultaneously display several streams from various sources and source types in any size, configuration or aspect ratio that is desired, across the single logical surface formed by the multiple monitors joined together.
Professional high-end controllers bring many other additional benefits like the ability to enable internet access, allowing to display live web sources on the video wall or other apps, like clocks, dashboards, or emergency messaging, all at the same time. In addition to that, they can mix both baseband and IP sources and display them anywhere on the wall. Some even come with control panel designers that would allow you to design buttons on any computer or tablet that would permit users to change layouts on the video wall with a simple click of a button. The right video wall controller can deliver a high level of flexibility and achieve incredible processing performance, resulting in an infinite number of custom configurations for impactful and effective visualization experiences.
