IMAX Enhanced coming to Disney+ on Friday

[Oski1997]

It’s not a lossless DTSX, is it? Guessing it’s the lossy version but still might be more bandwidth than DD+ with Atmos metadata.

It’s the lossless version (DTS-HD MA). It’s the only lossless audio version available through streaming. It’s only available through the Bravia Core app that uses IMAX Enhanced. That’s why it requires 115mbps internet speed.

There doesn't seem to be a timeframe for the DTS:X tracks on the Marvel movies that I can find so if anybody finds any info, do tell. I'm curious if these versions will see their way to 4K disc or will be Disney+ exclusives.

Right now, the only DTS-X (DTS-HD MA) version through streaming available is by using the Bravia Core app on 2021 Sony TVs through their Bravia Core App that has IMAX-Enhanced that requires 115mbps internet speeds. One thing I really like about “DTS-X” is that it always includes DTS-HD MA. Dolby Atmos can include Dolby TrueHD or DD+ which is the lossy version. This makes the “Atmos” brand more confusing. With DTS-X I always know it’s the lossless (DTS-HD MA) version.

Right now, the only Blockbuster movies available on IMAX Enhanced with DTS-X on 4K Blu-ray are Jumanji (the Next Level), Bad Boys for Life, A Beautiful Day in the Neighborhood and the new Charlie’s Angels movie

So is this via the specific Sony 2021 TV and the AVR being used would be required to have EARC capability?

Yes it’s only through the Sony 2021 TVs that have the required HDMI 2.1 port and AVRs that are IMAX Enhanced certified.

So the AVR not only has to support eARC, it requires a HDMI 2.1 HDMI port and also an “IMAX Enhanced Certified” AVR mode/feature?

It's a bandwidth issue as far as streaming goes. Only Atmos tracks on disc have TrueHD at their core and anything streamed has Dolby Digital Plus 7.1 at its core. I'd be curious if anything is streaming in DTS:X just yet and haven't found anything that says Bravia Core is using it, yet. Seems IMAX Enhanced titles are in HDR10 on Bravia Core but in Dolby Vision on Disney+. But, since when do these folks all get on the same page at the same time? Not a bad experience no matter how you get it right now but these IMAX Enhanced Marvel movies in DTS:X would be nice to have on disc.

I would be more in favor of a streamer device that connects to the AVR that can forward Lossless Atmos or DTSX if an app supports them and internet bandwidth is large enough. Such as an updated AppleTV or FireTV or Roku.

I’m not in favor of IMAX creating some remix codec that isn’t really true DTSX lossless and forcing you to buy both a TV and AVR with the IMAX codec.

 

[Trebdp83]

Well, you can bet any implementation of DTS:X over streaming will be lossy to start the way Dolby Atmos still is over streaming. Interesting to see IMAX Enhanced and DTS finally making some real noise. Reminds me of the 90's when THX DTS laserdiscs were the thing for getting the ultimate movie watching experience in the home.

 

[Huey645]

I'm really liking the Imax Enhanced format. Watched Avengers: Infinity Wars, and it's never looked better. Hoping they release more titles using this.

I agree, the colors are more vibrant in IMAX-E

I support this argument that it is lossy DTS if played from TV's internal app. Let's stop and consider a few bits.

It must be loosy, unless MediaTek has finally designed TV chipset that can natively output lossless audio via wider eARC channel from internal apps. No TV can do this at the moment, hence all current TV apps output lossy Atmos via HDMI eARC. Is there any new SoC that those TVs use? I cannot see any MediaTek SoC for TVs that has native eARC build into boards, which is fundamental for any lossless soundtrack played from internal apps via HDMI.

Increase in streaming bandwidth is a marketing gimmick that distracts. WiFi 5 is several times faster than 115 Mbps and most TVs have it. HDMI 2.1 port is not necessary for those movies. Those movies have to fit into 18 Gbps pipeline, so HDMI 2.0. Apps might support lossless audio in software, but if TV's chipset does not support it in hardware, lossless audio cannot go out via HDMI. In the TV spec on Sony's website, I cannot see DTS:X mentioned anywhere. Am I missing something?

It reads: "It uses DTS Sound with its own optimized version of the DTS:X codec". What does this really mean?

 

[Oski1997]

The easiest way to find out is if someone with a 2021 Sony TV with the Bravia Core app (with at least 115mbps) can take a screen shot of their receiver‘s audio info when streaming an IMAX-E movie on the Bravia App. If it shows IMAX DTS:X then we know it’s lossless. Can anyone on here help? Sony’s website says the following:
The BRAVIA CORE™ app is a video service included with eligible TV models. This app offers access to a range of new releases and classic films, including the largest IMAX® Enhanced movie collection, lossless UHD quality with Pure Stream™, and more!

“Optimized version“ means that IMAX configures the DTS:X codec with specific IMAX settings that include a frequency response, max SPL, impedance, sensitivity, audio curves 1 octave lower in bass, etc.

Is Bravia Core app installed on TV only or can be installed on external devices?

It’s only on 2021 Sony TV’s (maybe some 2020 Sony TV’s too)

ok. Do we know which model of SoC from MediaTek do those TVs use?

No idea. If anyone on here knows Gene from Audioholics well, maybe they can ask if he can show us a screen shot of his receiver audio info while playing the Bravia Core app to see if it shows IMAX DTS: X. He has a 2021 Sony TV.

So, normal versions of DTS:X

• DTS:X Master Audio - contains a DTS-HD Master Audio lossless core. Used on discs.
• DTS:X - contains a DTS-HD High Resolution Audio lossy core. Used by streaming services

Which one does IMAX use? It is hard to believe that any streaming services on the planet use lossless Master Audio, like the one embedded on discs.

 

[AVR Enthu]

IMAX DTS: X.

It is not enough to show that, because there are diffrent flavours of DTS:X, like with Dolby Atmos.
Dolby Atmos/DD+ - lossy Atmos (Netflix and others)
Dolby Atmos/DT-HD - lossless Atmos (discs)
