Sorry to hijack the thread but I just want to make sure about something. I have a 1080p 3D TV and a Yamaha RX-V375 av receiver which allows 4k passthrough but only 1.4 I believe. Will the V6 play nice here or is it going to throw up errors because it's not 2.2.
I used one for a client who had SkyHD and wanted to split it to a digital TV modulator for distribution around the house over existing coax. It worked great. If you try this or another brand, then I hope you have the same success. Best of luck.
v1.4/1.4a that supports HD and UHD at up to 3840×2160 (Ultra HD) at 24 Hz/25 Hz with 3D, but no HDR.
v2.0/2.0a/2.0b that supports HD and UHD at up to 3840×2160 (Ultra HD) at 60 Hz with HDR.
Current versions of HDCP are v2.0/2.1/2.2
AFAIK the Tivo supports HDMI v1.4 with HDCP v2.0 and the V6 HDMI v2.0b with HDCP 2.2.
To pass the TV signal from the Tivo to your TV via a receiver, the receiver will have to support HDMI v1.4 (but will not output 3840×2160 (Ultra HD) at 60 Hz with HDR) or v2.0 (v2.0 is backwards compatible), but more importantly HDCP v2.2 as this does not downgrade. If the receiver does any type of processing on the content (upscaling, etc.) then it can output to a different standard, such as HDMI v1.4 with HDCP v2.0 if this is all that your TV supports.
As other posters mentioned, an HDMI splitter that strips out the HDCP copy protection will get around this (but might be illegal).
I've just realised I was getting HDMI and HDCP mixed up. A lot of that went over my head but am I correct in thinking that the V6 box would connect to the av receiver that has 4k passthrough at HDMI 1.4 to a 1080p TV absolutely fine?
Another possible way to connect the V6 box is to connect directly to tv as you have done and then connect the tv's hdmi 2 to the out of your AV receiver. Hdmi 2 has ARC you should then hear the audio from the V6 box via the AV receiver.
