HDCP (High Definition Copy Protection) 2.2 will become mandatory for 4K/UHD content only. First source should be the 4K BD player announced at IFA for spring 2016 from Samsung. In case of HDCP 2.2, the whole chain needs to be compatible to work from source to AVR to TV. If one of the devices in the chain is not HDCP 2.2-compliant, the player will downscale the content to 1080p. No black screen. This is the theory, anyway. HDCP 2.2 is copy-protection, so it does not decode the signal, but is concerned with preserving the content from being copied and distributed on the internet. The problem of HDCP 2.2 is that it is hardware-based, and not software-based, so there is nothing we can do on our existing models, like any other AVR manufacturer or TV. Please note that self-produced 4K material is no problem, since self-produced material has no digital HDCP copy protection. Only streamed material and UHD-Blu-ray will not work, since the HDCP protection will stop the signal in the receiver.
