Video Processors transform video input signals to viewable content. The video sources are typically HDMI, DVI, or VGA being sent from media players, cable boxes, or computers for displaying on TVs or projectors. The term “Video Processor” encompasses an array of devices including Matrix Switchers, Amplified Splitters, Multiviewers, Video Walls, and Presentation Switchers.
The most common device utilized in both commercial and residential applications is a Matrix Switcher capable of delivering 4K and 1080p video from multiple sources to multiple displays. These types of switchers can typically scale resolutions and accept audio connections like Digital Coax, SPDIF, and Analog RCA. A common application example would be a Sports Bar, Mall, or anywhere visual imagery can make an impact.
Amplified Splitters are designed to split a single video signal and distribute it to multiple displays, basically duplicating the same image across all displays. These devices are used in many retail shops, transportation facilities, and malls for advertising and Digital Signage. They can also be combined with Matrix Switchers to help with costs since Matrix Switchers are more expensive if they require more than eight TV displays.
Multviewers are the way to go if the application requires a video processor showing multiple sources on a single display. There are typically two to six HDMI input connections and one HDMI output for the Display. This device is found in environments like business conference rooms, entertainment venues, restaurants, and schools.
Video Wall Processors typically accept one source signal for the purpose of displaying it on four TV displays, combined to make one large screen. There are different types of configurations and layouts including 2x2, 3x3, and 4x4 for entertainment purposes. But for those interested in digital signage where you’ll rotate displays either vertical and horizontal, most Video Wall Processors will also support layouts like 1x2, 1x3, 2x1, 3x1, and 4x1. Video Wall Processors are used in airports, sports bars, malls, schools, healthcare facilities, business offices, and residential homes.
Conference rooms require video processors in the form of Presentation Switchers ideal for displaying materials transmitted from employees' computers. These switchers usually have HDMI and wireless connections using technologies like Miracast and Airplay that simplify connectivity. Some Presentation switchers offer USB-C, USB 2.0/3.0, DisplayPort, and even VGA connections for hosting a variety of devices.
