C2G has released “Ghost in the HDMI Machine,” a new white paper available for free download that offers an in-depth look at the challenges of extending HDMI connectivity beyond its 15-meter passive connectivity limitation.
Written by Legrand AV technology evangelist Joseph D. Cornwall, CTS-D/I, the paper dives into why the high-bandwidth connection is sensitive to a number of issues arising from manufacturing decisions and installation environmental conditions and how integrators can better ensure dependable operation of client’s media projects.
“HDMI is both the single most significant connection — and challenge — of 21st century AV design,” Cornwall says. “While we’ve certainly come a long way since the inception of this technology, there are still times when a well-done installation mysteriously runs aground. At that moment, it’s often difficult to pinpoint the source of the problem. That may lead to some intensive hours spent troubleshooting and ordering equipment. This white paper is the result of our intensive research and analysis and exposes what lies at the heart of many HDMI extension problems — proper application of power. Our goal is to help integrators anticipate, avoid, and address HDMI issues efficiently and effectively.”
Key information highlighted in the paper includes:
— The potential and reasons for HDMI failure because of voltage starvation;
— The role that the I2C HDMI transport protocol, chip sets of active copper and active optical cables, and more play in payload complexities;
— A power supply analysis of tested sources;
— Mitigating HDMI extension link issues today.
