Windowing Video Processor

DEXON’s DIVIP video processor displays direct input signals over multi-screen video walls. Services as real time scaling, seamless switch, fade effects ensure professional video quality. Demanding AV projects from 4×4 to 144×72 can be supported where remote operators use browser-based, graphics user interface for layout management.

A central element of demanding AV projects, the video processor  is a control box that processes and transforms input signals to viewable content over a multi-screen video wall. The input signals usually come through HDMI cables from media players, satellite receivers or even PC screens. Input signals are then displayed in any size and any position regardless of the monitor boundaries.

The video wall is a coherent screen of multiple displays usually 2×2, 3×2, 3×3, 4×4 or up to 144×72 size. Over these screens, information must be displayed in its highest quality regardless of the monitor borders. A video processor treats these separate monitors as one giant wall surface, hence the name —video wall. We need to note that a video wall has a great pixel count as it needs to display a single video signal across all available pixels over the video wall. The resolution usually varies from VGA up to UHD. The input signals are processed and are mapped to the output surface. During this mapping scale up or scale down is usually needed while the signals must be displayed in real time. This means there is no room for latency or frame drop.

Our video processors provide all functions you need when it comes to displaying the content over the video wall. Then you can scale up or scale down this video to a smaller size, a larger size or any other position. You even have the possibility to place this over the entire surface of the wall. Via the user interface, you can assign different user rights to each operator, to ensure a smooth collaboration and a clean video wall.


All industry standard signals, resolutions must be supported for the input and output signals by DEXON’s 4K video processor. The resolutions vary from XGA up to FHD or even UHD. The input signals are processed and are mapped to the output surface. During this mapping scale up or scale down is needed and the signals must be displayed in real time. This means there is no room for latency or frame drop.


The users of the video wall share information for the audience to be informed, entertained or make decisions. Such video walls give the chance for the central management of traffic, network traffic and industrial process based on central decision making. The audience has the chance to open and share local information or even use other participants’ screen information.

How does a video wall operate?

You can open a video window over the video wall then place this video in any position by simply dragging it. Scale up or scale down this video to a smaller size, larger size or any other position. A video can even be placed over the entire surface of the wall.

Layout management

We offer limitless display possibilities for your input videos over the video wall. We can place one input to each screen, or place each input as a quarter of a screen. Or even recall a previously saved layout that displays 16 live video inputs.

The management of the video wall surface must be supported by an easy-to-use user interface. In this interface, you are able to save your favorite layout settings and to recall them at any time in the future. This means you can reach your previous designs just by one click!

Presentation effects

Video processors provide attractive presentation effects to create a visually appealing experience for potential users and visitors.

  • You can open a video as a background and place it over the video wall. Then place further videos as picture in picture up to 8 videos in real time.
  • On-screen-display allows placement of small text over the video windows. For example, this can show input and output parameters or customized text.
  • Use seamless switching to open one video, then switch it to another content with 0 latency and without any distortion or black frame appearing in between displayed videos.
  • If you wish to replace an input, you can do so by applying the cross-fade effect. This means one image will slowly fade out while the other one fades in without the background appearing in between. All these effects can be achieved by simple drag and drop operations.
  • Fading in means that a video image will open slowly by fading in from the background. You can customize the time frame to your application
  • Fade out effect means when closing down the displayed videos, they slowly fade out into the background. You have the possibility to set the desired time also.

Application Areas

The application of video processors is rather broad as video walls are needed for boardrooms, showrooms, department stores, even in education for universities and high schools. They can also be integrated in mission critical control rooms for police and government systems.

DEXON’s best video processors make real time visualization possible and allow for attractive visual experience thanks to the fantastic built-in presentation effects. The main advantages are scaling-up and down of the signals up to 4K30 or even 4K60, you can display your inputs in any size and any position over the video wall, you can apply the PIP function and many more effects like seamless switching, fading effects and OSD. Therefore, such a device is the central element for any successful AV project, providing you the experience and video information for amusement, for being informed and lastly for smooth cooperation.
