If there was an excitement meter for the various components of a digital signage system, cabling would barely register. People like to talk about high-definition (HD) video, interactive capabilities and extra-large displays while cables literally hide in the background. However, as HD becomes ubiquitous, cabling for digital signage becomes more complex. Many organizations are struggling to send HD video over long distances in a way that’s reliable and cost-efficient. It’s not as simple as buying an HDMI cable for the 55-inch flat-screen TV in your living room.
