Back to Apple TV being an App on Roku.

Tested this out with 'Wonders of the Monsoon' EP1 tonight which is a HD programme, I'm sending 4K HDR from the Roku SS+ to my non HDR Sony Bravia, so upscaling on the SS+. Dare I say that it's looking better than the same programme on AppleTV4K. Stunning video.

I suspect that the usual practice of Roku sending brighter and heavier contrast at base level is helping. There's still some horizontal judder on horizontal pans which has to be looked at carefully to notice too.

I don't understand "I'm sending 4K HDR from the Roku SS+ to my non HDR Sony Bravia"? What do you mean? Do you mean your Roku is letting you play HDR content to an SDR display and the Roku is tone mapping down to SDR, or that your TV is tone mapping down to SDR, or that you are watching an HDR Rec 2020 gamut / ST.2084 EOTF (i.e. HDR10) video output unprocessed on a Rec 709 BT.1886 (or 2.2/2.4 Power Law gamma) SDR display? (The latter would look flat, desaturated and with very odd black and white levels)

The Roku is manually forced, overriding the automatic setting, to send 4K HDR to the Sony Bravia, which is taking the content in that format onboard and displaying the content wonderfully. I presume the Bravia is doing any processing required to display the alien content.

That's unusual - I didn't think SDR TVs currently on sale would accept Rec 2020 and ST.2084 content and do anything sensible with them (like tonemapping/gamut conversion). (Though there are 1080p HDR Sony TVs on sale now that will happily display that format in HD, but they won't accept it in 4K AFAIK)

I've got a SS+ - I'll have a play on my non-HDR Sony UHD TV when I get a chance. (I know that the Roku will output iPlayer UHD HLG HDR stuff on HD SDR displays without conversion - but because it's HLG the EOTF doesn't cause many issues as it's backwards compatible, but the Rec 2020 gamut displayed Rec 709 looks very off)

Of course the Sony, could be sending a I don’t understand you silly Roku message back, which then countermands the HDR manual setting, without telling me, but that’s taking technical tautology to almost B***** they extremes.


Yes - that's how EDID is supposed to work, and usually does. The only time I've got a Roku SS+ to output HDR to an SDR TV has been when watching iPlayer UHD stuff. (Desaturated and slightly odd highlights as per a Rec 2020 HLG EOTF signal displayed on a Rec 709 display in SDR)

Netflix and Amazon stuff has only been the SDR stream when watching shows that would normally be available in HDR on an SDR display.

AppleTV+ has launched. No surprise late offerings but Episode 1 of ‘The Morning Show’ is available for all to watch free on the AppleTV app, which I don’t recall being suggested previously. The range looks worth at least a month or two, there are other works in the pipeline too. The Elephant Documentary looks like being the standout offering in UHD at the start afaics. The key element is how they manage the flow of material to ensure interest continues going forward.

I’ll take the trial tonight.

EDIT:
There’s more free content than I first noticed. Will need investigating further.

Episode 2 is as well, but they make you take the trial for Episode 3.

I've just watched the first episode of 'For All Mankind', the storyline seemed disjointed and needed a lot of concentration. Some of the indicators looked far too 2019 rather than 1969 in the recreation of the Mission Control areas. The twist was well executed though. Viewing part two is pencilled in for tomorrow night. Going to give the Elephant documentary a run later in the week.

We'll see.

iTunes seems to be running a catchup exercise on TV content that was hurriedly added to the store between 2008-2012 that was produced in HD, but only available to purchase in the store in SD.

One of these series being Frozen Planet that has been available on Amazon in HD for a while, but now has finally become available in HD via iTunes. The Musketeers S1 also is now in HD. I believe there to be others too.
