10bit won't happen - you can see that in every "data sheet" out there. And the rest is not yet done - e.g. the decoder still fails and everything you get is an empty picture ... we are talking about HEVC_MAIN not anything 10 bit. I personally hope that at least [email protected] is working. So it is obviously clear that one will need again new hw, when the new livetv [email protected] HEVC will be the default (~2 years?). HDMI 1.4 limitations are also known ... So whenever I talk about this I talk about rendering at [email protected]something.

The BBC UHD test broadcasts were 2160/50p and 2160/59.94p at around 36Mbs and used 4:2:0 8 bit YCrCb format. I've not come across any 10 bit HEVC 50p/59.94p stuff yet - though I know that higher bit-depth is on the agenda for broadcasters, with or without HDR.

There are some 10 bit out there the Samsung one I've seen playing on a TV in a shop window locally. Maybe TVs are going to beat GPU/APUs for a while if they can only do 8. I guess the web streamers will just use 8 depending on the patent greed situation, perhaps x264 will be around for some time.

10 bit

I notice some Japanese samples also say rec.2020 which is a bit confusing as one I found has colour bars at the start that decode apparently correctly with a 709 matrix, but not a 2020 one.

This one also says 2020 (but doesn't have bars)

These are big! But as they are .ts you don't need to d/l all of then to get a working sample.
