I have read the American Bravia with X1 Extreme co-processor have got the Dolby Vision FW update. It is working with the Apple TV 4K? In the Sony forums there are people complaining that.. it is a mess. Did anyone manage to make it working?

The DoVi feature has been removed from the release changelog.
And remark about possible compatibility issues with 3rd-party sources added to product pages of A1E and Z9D.

Go figure.
I think Sony should outsource their software development and deployment to someone capable.

PS Would be interesting to know, if and how does current firmware update (version PKG6.2818.0075NAA) announce DoVi capability in Bravia's EDID.
SwitchResX is one tool to pull that info from HDMI sink.
Current version 4.7.0 is capable of HDR parameter interpretation in EDID.

Without proper EDID data, aTV 4K would not know to offer the DoVi options in A/V resolutions menu. So this is the first prerequisite of them all.

Unfortunately, it's only working with the TVs onboard apps. They even updated the firmware on the website and it doesn't even mention Dolby vision.

It's a different firmware number but from what I can tell the only thing that changed was the release notes.
It was also PKG6.2818 this morning, when DoVi was still listed as a feature. Not sure about the 0075NAA part any more.

Oh.. all right. Thanks guys. So it is even worse than I imagined. That Android TV on Bravia will never work at this point. It has issues everywhere. Even in a key selling point like DV, now. Unbelievable.

I updated early yesterday morning. The release notes page said 0070NAA but the release my TV received was 0075NAA. Guessing they just removed the reference but the file is the same.
Would you be able to pull the EDID data from your Bravia then? Just to see if and what evidences it may contain about new HDR mode.
For reference, my HDR10/HLG-olny firmware currently lists this:
Code:
EDID report generated by SwitchResX Version 4.7.0a2 (x64) for display SONY TV  *00

When I constantly read about TVs having software problems or not this this right or whatever, it truly should make us all realise what a beautiful device the Apple TV 4K really is. Yes there will always be moaners that say, it doesn't play lossless or this or that, but they are disc users anyway and i'm sure that they'd find fault with something else because that's their style.
The fact the ATV is worry free is wonderful. I'm also happy that I have a basic, but brilliant performing 40" Panasonic EX700 TV. It's something that I never find fault with.

It is! I finally have a great media player. Which is Infuse. I basically bought the ATV 4K for it. I've tried all of them in my Bravia for Android TV and I became exhausted of dealing with an issue or another. Sony's Video would play just anything, but the subtitles support is minimal (English is my second language and I need written support with some of those crazy Anglo-American accents out there.. :D ).

Oh, Amazon Prime Video finally play without stuttering the audio. I can deal with 2.0 audio on 1080p videos. Hopefully it will be fixed soon..

Yes there will always be moaners that say, it doesn't play lossless or this or that

Well.. One of the biggest complaint on Bravia is the broken API for the audio passthrough. It only plays DD/DD+ 5.1 and AAC 2.0. Although most audio formats work with Video (and only with it). So I find it a bit disgraceful that tvOS doesn't support it. Together with the Hi-Res audio.

It's a 200€ box I do expect (pretend?) it to be implemented. But yet again, Infuse has the codecs for it, so spending another 50€ for a lifetime subscription the problem (at least for local media) is solved. Or manually installing Kodi every week. Of which I don't mind. The problem is Kodi in tvOS isn't perfect either. The Dynamic Range Matching isn't working (yet) for example.

Then that YouTube app needs to be updated. It's from 2016. The AVC 4K videos are there in the servers.

Sony responds to Dolby Vision controversy
https://www.flatpanelshd.com/news.php?subaction=showfull&id=1516616887

More updates required
Last week, Sony finally started rolling out the Dolby Vision update to its A1 OLED, X93E, X94E, and Z9D models in the US. The same update will roll out in Europe next month.

However, while the update works as expected via streaming apps (Netflix), it does not work via HDMI sources such as Apple TV 4K or UHD Blu-ray players. After waiting for almost a year for the update to arrive, owners are frustrated and disappointed. We have pressed Sony for an answer since the update was released last week and received the following statement from Sony Europe today:

- “Select Sony TVs will support Dolby Vision with the software update to be rolled out in Europe within February, 2018. After the Sony TV receives the software update, devices with Dolby Vision playback (such streaming media players and UHD Blu-Ray players) that are connected to the Sony TV by HDMI will also require a software update to support Dolby Vision playback through the device. For more info on the timing of an update to a particular player, please contact the player’s manufacturer.”

If you are confused we can understand why. To date, Dolby Vision has required the TV to process the dynamic metadata, meaning that if the playback device outputs in Dolby Vision, your TV will accept the signal. However, Sony has implemented a new Dolby Vision profile that offloads much of the processing to the playback device, likely because the processor in Sony’s TVs lacks the capability or power.

Sony did not go into further details of the technical implements or explain why it has chosen this approach.

But there you have it. Your Dolby Vision playback device, meaning your UHD Blu-ray player or Apple TV 4K, will need a firmware update in order to be compatible with Sony’s TVs. Oppo has said that it will deliver but Apple and others have yet to comment on the matter. Sony will release its first Dolby Vision-capable UHD Blu-ray player this month but the update to enable Dolby Vision on the player will not arrive until “summer 2018”. We expect the X700 player to compatible with Sony’s TVs by then.

Not happy with what Sony did with the update, but I am hoping Apple with fix this with a firmware update for the Apple TV 4K.

I sent a feedback to Apple:

Dolby and Sony share responsibility for this mess (though, I blame Sony more because this information wasn't revealed to X1 Extreme Bravia buyers in advance). Dolby is apparently struggling to bring Dolby Vision to wider acceptance. And now HDR10+ is trying to steal Dolby's thunder and I suspect Dolby is concerned.

Basically, Dolby is allowing a VARIETY of different decoding schemes for Dolby Vision. Decoding happening entirely in the TV, part in the TV and part in the HDMI device, and also entirely in the HDMI device. It's a royal mess.

Vincent Teoh at HDTVTest posted this very up-to-date video this morning:


I own the Sony XBR75X940E. I installed the Dolby Vision firmware update last week. I quickly discovered that six 4K Dolby Vision titles on my Apple TV 4K wouldn't play in HDR on my Sony 940E. I have other 4K Dolby Vision titles on the Apple TV 4K that still play in HDR on my Sony 940E. Why some do and some don't is beyond me. I can force those six titles to play in HDR10 by manually switching the 940E's HDR Mode to "HDR10" instead of "AUTO". But that causes SDR content to play back in HDR10, which looks horrible. Constantly switching back and forth between HDR10 and AUTO is far from an elegant solution.

So, I'm anxious for Apple to update the Apple TV 4K to support this "low-latency profile" Dolby Vision scheme that Sony is using (with apparent full support from Dolby Labs). I've already used Apple Feedback (twice) to ask for a quick resolution to the issue. I have my fingers crossed that Apple issues an Apple TV 4K update quickly and crossed even tighter that the Apple TV 4K's hardware can properly support the extra decoding requirements that this Dolby Vision scheme obviously requires.

I'm not upset with Apple about this but I am VERY unhappy with Sony. The 940E is the first Sony brand product I've purchased in over 20 years. It will be the last.

Why not with Dolby Labs, instead? How is the years-long deployment of buggy DoVi implementation (the elevated black levels issue) on LGs and Vizio-s any better, than releasing a firmware that is now "ahead" of the rest of the market?

I agree on one thing - Sony could have avoided much of this useless talk on open now, simply by doing their communications better.
The amount of various theories in the wild now, is just amazing.
Most of them have no factual explanation, just emotions.

For average consumer, things will not settle before one HDR standard emerges as winner on the market. I would not want to bet if that will be Dolby Vision. May well not be the case, simply because of licensing issues and sheer expense for content creators. Any open and free solution can be more accessible and affordable to the masses.

Heck, you and me are already in the position to issue our home videos in HDR10 or HLG (the latter even comes directly out-of-the-camera from Sony a7R3!). Would not surprise me to see similar developments in other cameras, even iPhone.
Try this with DoVi!

Whoever is to blame I seriously don't understand why the Bravia have enough CPU power to process the DV streams from Android apps and not from the HDMI.

Regarding all the speculations that is what one gets when a company promises one thing and then, once delivered, they have to specify "as long as the HDMI devices support that particular Dolby Vision profile we have implemented no one has ever heard of before".

This is what one gets allowing the marketing people talking out of their.. bottom (as usual) without consulting first with the engineers. Oh, I am still waiting for the long promised HDR on YouTube to be clear.

My very first sentence in the message you partially quoted was: "Dolby and Sony share responsibility for this mess (though, I blame Sony more because this information wasn't revealed to X1 Extreme Bravia buyers in advance)."

But Dolby Labs didn't sell me the TV that isn't compatible with with existing Dolby Vision external devices, Sony did.

[doublepost=1516812629][/doublepost]Any Sony A1 Extreme Bravia TV set owner that still believes that Sony will eventually offer a different firmware update to fix the incompatibility with Apple TV 4K can stop holding their breath.

https://www.forbes.com/sites/johnar...em-update-sony-and-oppo-respond/#4501965a498a

Although there may be tweaks to the firmware for one reason or another, what we got now is what we'll continue to have. The Apple TV 4K (and other external Dolby Vision HDMI devices) will require a firmware update to be compatible with the mentioned Sony TVs. Period.

This seems similar to Dolby Digital and DTS decoding... a blu ray or DVD player can decode them and send it out as Linear PCM for all the channels... or it can send the actual DD and DTS data to the next unit in the chain to decode. If it's a TV and you turn off your speakers, it'll pass that through then thru an ARC or Optical... and if it's a receiver either directly after the player or after the TV, that can then decode the data and send out the channels.

I like that idea... having the choice where in the line it gets decoded. However, I don't like the thought that my "receiver" (as it were) only accepts the decoded message.

Why should Apple have to fix anything? Their ATV is performing well on both LG (& BANG&OLUFSEN badged C7) and Loewe TVs. Surely the Apple TV is perfect and it is SONY that need to do a proper job??? Don't forget Apple has invested 2Billion dollars in LG. Chances are, they really do not care about SONY, their TVs and their funny disc players.

I have a XBR-49X900E which is 4k and HDR. My AppleTV correctly displays 4k+HDR and is even in Chroma 4.2.2 vs the 4.2.0.

The AppleTV correctly detects and outputs 4k@60Hz in HDR.

However, I have to note, that the AppleTV connects first to a Bose Soundbar. The soundbar sends the signal (video only) to the TV to HDMI port 3 (ARC). I have Enhanced-HDMI enabled also.

I have the latest software for the TV available as well.

Just throwing i my $0.02

That is how aTV 4K has been working since launch.
The problem is specifically with Dolby Vision format of HDR (yes, there are several in use at the moment, before one clear market leader emerges).
And more specifically, Sony decided to implement this via a feature of HDMI2.1 protocol, that no source has support for, yet.
