I have raised this concern also. I think there is a significant number of TVs with this limitation and OHC could take a closer look if this could be added to the firmware wish-list.

RE: UB820V
Of Course it all starts with what content is coming out in 4K 60Hz in YCbCr 4:2:0 or YCbCr 4:4:4.

Buying a 4K TV without a clear standard is taking chances...

Some focus on problems and faults others on solutions and success... no question who is the happy one.

RE: UB820V
Yep you need to wait or buy one that does support your TV. Or buy a TV that will do both.

The PCH Vten uses 4.2.0 and the OH 4.4.4, we'll see which one wins the Bluray4K format war.

I don't think you can just add it to a firmware its chip specific and the RK3288 does the higher spec but as Willem and I allude the spec is not set yet.

Several equipment (i.e. OPPO Bluray players) allow you to setup the output as either 4:2:0, 4:2:2 or 4:4:4, that is why I believe it is possible to implement it via firmware (since OHC is capable of the most difficult one, which is 4:4:4).

RE: UB820V
in wich case the OP request is not part of the standard:

And a UB820V 4k UHD that supports 4K 60hz in YCbCr 4:2:0 8 bit ONLY will be a problem

According to heise.de will be the 10 bits transfered as 8 + 2, and decoding engines that request 8 Bit will work and let the additional 2 Bits left. So the TV from the OP will work as long, as the TV have HDCP 2.2.

RE: UB820V
Rec. 2020 defines a bit depth of either 10-bits per sample or 12-bits per sample.
Rec.709 does 8bit but how that sits with YCbCr 4:2:0 is above my math today..

Yes you are true, but the CT' says that the 10 Bits there splitted into 8+2 for downwards compatibility.

;-) maybe but anyway, the UB820V mets the requests of 4k BluRay. I assume they have looked at all the 2014 TVs and standardized a minimum that all tellys can show

RE: UB820V
It all just makes me more determined to wait, along with the fact that they get cheaper.
