What are Extenders Splitters and Other Distribution System Products For
For digital signage maximum reach and image control, you’ll likely need media extender products that enable you to extend, split, or switch between video signals, or manipulate images to fit your screen setup.
These video transmitter/receiver enable you to send DVI, VGA, or HDMI (as well as audio) from a network or PC to remote digital signage displays. UTP-based extenders work over CAT5 or higher-grade cable, which means you can use inexpensive wiring for your long-distance runs, Fiber-based video extenders support extended, interference-free runs over fiber optic cabling. The extender products also includes baluns, compact devices used to match or transform an unbalanced coax cable to a balanced twisted-pair cable.
A video splitter is a device that a signal from a video source or player and replicates it over multiple displays.
The number of times that a video splitter divides the signal varies; video splitters currently on the market provide divisions for as few as two ports or as many as hundreds of ports.
There are two main types of video splitters: standard VGA, DVI, HDMI video splitters and Cat 5 video splitters using extenders.
Standard VGA Video Splitters:
Standard VGA video splitters allow a single VGA, DVi or HDMI source to simultaneously drive 2, 4, 8, or 16 displays.
These convert signals from one video format to another type of video format. Some also work as video scalers.
Another important element in a digital signage system is the cabling. This infrastructure transmits the digital video signal and audio from the player to the displays, and it’s a key factor to actual digital signage performance.
The cabling technology used can take advantage of an existing infrastuctor, such as your data CAT5 Cables, or be backbone fiber, UTP, or coax runs, or a combination of various media type. Both copper or fiber communication offer superior data transmission. The decision on which one to use may be a chalange. It often depends on your particular on site situation, including bandwidth, distances, environment, cost, and more.
