Gefen’s New Digital Signage Daisy Chain System Delivers HDMI to 100 Displays using Video over IP Technology

At DSE, Gefen will demonstrate how its new digital signage Daisy Chain HD System can create a large daisy chain of displays using a single CAT-5 cable. The system includes a sender, splitter and receiver unit—all interconnected in a daisy chain concept. All three units maintain 1080p full HD in the HDMI format with RS-232 and IR.

Similar to a tree scenario, the system uses splitters to create new “branches.” Users can create up to ten branches each supporting ten displays. Individual displays can be mounted next to each other or up to 100 meters apart.

Source video is sent to the sender then over a CAT-5 cable to the splitter. The splitter outputs two signals: one which can connect to a display through a receiver up to 100 meters away; and another which connects to another splitter. Each splitter also provides one HDMI output for a local display connection.

Alternatively, this Daisy Chain HD System can create a straight daisy chain to 30 displays from one splitter to the next splitter or receiver.

This new daisy chain video system works with all hi-def displays and video sources using HDMI including Blu-ray players, satellite set-top boxes and tablets.

“This is a new daisy chain concept for digital signage,” said Hagai Gefen, president, Gefen. “The video source can be routed to many locations and integrated to support large display deployments such as airport terminals using up to 100 displays in one system.”
