I’ve been playing with ambient light for my TV for a while now, as you can see in the “Ambient TV lighting with XBMC Boblight, Open Elec and WS2811/WS2812 LEDs“, to make colorful lights (LEDs) light up matching the video you’re seeing on your TV.The downside of that project is that it only works for a dedicated HTPC running for example Kodi (XBMC).But what if I’d like to see this with video from my XBox 360, XBox One, Wii, or … Besides the fact that we need to grab this video, and all it’s technical complications, we will be running into a copy protection issue called HDCP, a HDMI feature nobody really asked for.
The content, or content source (where the “output” comes from), determines if HDCP is needed, and is/was intended to prevent content to be displayed or recorded by unauthorized devices.
Just like those idiotic region codes of DVD’s and Blu Ray’s.
Non compliant devices, an old (HDMI) TV for example, will simply display a message that the content cannot be displayed written with illegal copying, ripping or to promote piracy.
However, as soon as you play HDCP content (Amazon Video, Netflix, Hulu, etc), your screen will turn black.
Another, much easier and cheaper method, is the use of a HDMI splitter.Another commonality seems to be that they appear cheap China products.
