Second Beta of tvOS 12 Now Available for Registered Developers

by

Apple today seeded the second beta of a new tvOS 12 operating system to developers for testing purposes, two weeks after releasing the first beta following the 2018 Worldwide Developers Conference keynote.

Designed for the fourth and fifth-generation Apple TV, the new tvOS 12 developer beta can be downloaded onto the Apple TV via a profile that's installed using Xcode. Subsequent betas can be downloaded via the software update mechanism on the Apple TV.


tvOS 12 brings support for Dolby Atmos sound. Apple says that iTunes will be home to the largest collection of Dolby Atmos-supported movies anywhere, with Apple upgrading titles customers have purchased for free.

Building on single sign-on, a new zero sign-on feature will further simplify the cable authentication process. With zero sign-on, the Apple TV can detect a user's broadband network and automatically sign them into supported apps they receive through their cable subscription.

Aerial screensavers include location information and there are new screensavers captured in collaboration with the International Space Station.

Other improvements to Apple TV in tvOS 12 include AutoFill passwords from iPhone, an Apple TV Remote automatically added to Control Center on the iPhone or iPad, and Apple TV support on Home control systems like Control4, Crestron, and Savant.

tvOS 12 is available for developers for testing purposes and will be available as a public beta later this month ahead of a fall public release.

It's DD+ with atmos. There's no way to know how apple is mixing in system sounds but the dolby spec requires the audio be unaltered. So whether they mix in system sounds or not the audio is the same.

But, when Apple does mix system sounds, what they do is decode, mix, re-encode PCM. I am wondering if Apple is passing the audio for the content only while the content is playing, this would be the better option, but, not likely.

Full list: 4K HDR (Dolby Vision) & Dolby Atmos movies on iTunes
https://www.flatpanelshd.com/news.php?subaction=showfull&id=1505495519

This list was started for 4K titles to show what HDR format is being used, surely there will be at least some (if not many) 1080p titles with Dolby Atmos, wondering if this list will include those or not.

If I have the Apple TV 4K which will support Dolby Atmos does my TV need to support it to if I don't use their built-in speakers?

No. Not if you aren't sending the audio to the tv. Typically you'd run it in a receiver.

Just FYI. Atmos is an option now but not working in Infuse or any other apps yet.
