CEDIA talks ARC

ARC (audio return channel) is a really neat feature of modern HDMI displays, but it is very limited in what can be delivered. Here, David Meyer explains a little about the boundaries and why DD+ and Atmos can work, but don’t always.

I was recently discussing with Australian integrator @Hemant Daya​ the use of HDMI ARC to deliver Dolby® Atmos sound from the Netflix app in a TV back to an AVR. But ARC doesn’t support Atmos, right? Well, not until the next generation eARC, that is. So why then does it appear to work (sometimes)? The answer is a little complex, and I felt well worth sharing…
