Gefen daisy chain system extends HD displays with video-over-IP

April 17, 2013

The digital connectivity solutions provider Gefen has released a new Daisy Chain HD System that creates a large infrastructure for wiring displays using CAT-5 cable. According to a news release, the system includes sender, splitter and receiver units, all interconnected in a daisy chain concept. The units work together to extend 1080p full HD with RS-232 and IR control signals using the same CAT-5 cable.

The company likens the system to a tree, with splitters creating new "branches." Users can create up to 10 branches, each supporting 10 displays, with individual displays mounted next to each other or up to 100 meters apart. Source video is sent to the sender then over a single CAT-5 cable to the splitter.

The splitter outputs two signals — one that connects to a receiver and display and one that connects to another splitter. Each splitter also provides one HDMI output for a local display connection. Alternatively, the Daisy Chain HD System can create a straight daisy chain to 30 displays from one splitter to the next splitter.

The company said the system works with all hi-def displays and video sources using HDMI-supporting Blu-ray players, satellite set-top boxes and tablets. IR and RS-232 controls key features, including powering displays on and off and switching source inputs.

Gefen President Hagai Gefen said the system is a good fit for commercial applications that use multiple displays, such as airport terminals.  

"This is an evolutionary new daisy chain concept for many commercial applications, particularly digital signage-type video walls," he said.
