What is the Difference Between Video Matrix Switcher and Videowall Processor?

The video matrix switcher can switch multiple signals from the input channel to any one of the output channels that are independent of each other, and can switch a variety of high-resolution video signals to various display terminals, such as NTSC standard and PAL standard. The videowall processor is a high-tech device that divides a complete image signal into several blocks and distributes them to serveral video display units. It is a large-screen dynamic image display screen composed of multiple ordinary video units, which can support the simultaneous connection of multiple video devices.


1. Video matrix switcher and videowall processor work differently


A video matrix switcher is a device that switches and outputs multiple video input signals to multiple display devices. Generally speaking, the number of input terminals is greater than the number of output terminals. For example, if we want to monitor the signals transmitted by 100 cameras on 10 monitors at the same time, we can use the video matrix switcher to switch. The video matrix switcher can be divided into HDMI matrix, DVI matrix, VGA matrix, AV matrix according to the signal format.Videowall processor divides a complete image signal into several blocks and distributes them to serveral video display units (such as rear projection unit) to compose a large-screen dynamic image display screen with multiple ordinary video units while multiple signal formats can also be processed simultaneously.


2. Display mode of video matrix switcher and videowall processor


The video matrix switcher can only display the transmitted video signal on the monitor intact, but the number of displayed windows can be adjusted according to the needs.However the video wall processor provides a variety of display modes, which can realize window roaming, signals overlapping, zoom, picture-out-picture tiling, picture-in-picture, window perspective and other functions, and preset multiple modes, as well as pre-layout modes.


3. Image processing of video matrix switcher and videowall processor


Strictly speaking, a video matrix switcher can only be regarded as a signal transmission device, which plays the role of transmitting signals. Although the signal quality delivered by different types of video matrix switcher is different, these are caused by hardware configuration limitations.Videowall processor plays more of a role in controlling and processing signals. It can not only divide signals, but also adjust images, such as color correction, high-definition digital signal processing, image docking and fine tuning, etc.
