A video input from a single source can be simultaneously viewed on multiple display devices with the help of a video splitter. Acting as a signal booster, these devices split the signals and replicate the same image on multiple devices without any loss in image quality. Compatible with NTSC, PAL or SECAM signals, they are available in a variety of sizes including 2, 4, 8 and 16 ports and can also be daisy chained together for larger configurations. Among the many models available on the market today, the more popular ones include: Component and Composite Splitters, DVI, HDMI splitters, S-Video, Quad screen, VGA and VGA Audio/Video Splitters. The only difference between them is the type of signals which they relay.
These units can also be known as video distribution amplifiers, the most common version of which is the VGA Splitter and the latest version is the new HDMI model. Where the former connects VGA displays, the latter relays both audio and video over a single cable rather than over multiple cables and can split and distribute single HDMI video signals from sources such as set-top boxes, DVD players, D-VHS players and other HDTV devices to multiple HDMI video display units simultaneously. Usually compact in size, these devices work on the simple plug and play principle. Control can be exercised using either push buttons on the front of the unit, via RS232 interface or through an infra red remote control.
Ideal for situations where information from multiple sources needs to be displayed on a single screen, the Video Splitter finds its use in digital signage, remote monitoring and broadcasting, presentations, educational and training institutes along with commercial centers.
