Looks amazing via SKY Q

Its missing the HDR though isn’t it? Sky Q boxes don’t support HLG yet.

Do they support any flavour of HDR? HLG, HDR10, HDR10+ or DolbyVision? HLG makes the most sense for a TV box - but HDR10 is the dominant flavour for catch-up and movies (you really need the whole show to derive the correct metadata for HDR10)

As they don’t offer any HDR content yet it’s not clear on a hardware level what the 2TB boxes (originally known as ‘Silver’) could support, presumably not DolbyVision as that would need hardware or probably more processing power than has been allowed for, not to mention the licensing fees. Possible they could offer HDR10, but from what you are saying it might be tricky as downloads are progressive so that you can start to watch them before they’ve completed. So maybe eventually it’ll be HLG?


At the moment they’re happy enough pushing 4K and Dolby Atmos (although BT were first with the latter of those).

No issue with HDR10 for progressive download, after all it is used by Netflix and Amazon for their HDR streaming.

The issue with HDR10 is that the metadata for it - strictly - should be completed at the end of the production (as it contains information about the brightest pixel and the average brightness - neither of which are available mid-show necessarily). It's possible to fix the metadata I guess - as US cable companies have used HDR10 for their UHD HDR tests (like the Rio2016 opening ceremony)

HLG doesn't require any specific metadata - and isn't using Perceptive Quantisation and SMPTE 2084 (Which nails a pixel's absolute light level output to the video signal's level)

Interesting that only low-end Sony UHD HDR sets are compatible. Any of their Android TV sets - including the high-end A1 OLEDs are not able to access the content. (Basically the 7-series are OK, but any 8-series or above is not)

This appears to be a limitation on the Sony side based on some tweets from BBC people, though no major public comments from either side yet. The fact that most other manufacturers have a much wider range of supported displays than Sony suggests the issue is linked to how Sony and Android TV are working at the moment.

Until Apple build, test and deploy an HLG codec it wont be.
