This audio would be PCM in nature so the audio it is being mixed into would also need to be PCM in nature.

The Apple TV app will more than likely allow the TV to access Atmos via DD+ encoded audio and this can be easilly bitstreamed to an external soudbar or AV receiver via ARC or eARC.Īpple apparently prefer not facilitating bitstreaming via the Apple TV because not doing so allows them to easilly mix in other sounds and audio created by the device or Siri. This is something LG say they are planning to resolve though. LG TVs that are eARC enabled cannot convey multichannel PCM via that eARC cnnection.

Until LG resolve the current inability to convey multichannel PCM via eARC on their TV or until LG update their TVs to allow Atmos to be accessed via the ApplTV app in association with DD+, you cannot as yest access Atmos in association with either the ATV device or the smart app if accessing that audio via any of the LG TV's digital audio outputs.īy the way, I've never said or even suggested that Atmos cannot be output in association with Netflix! This thread has been relating to the Apple TV app and consequently the Apple TV device. No LG TV has any anility to currently passthrough multichannel PCM. The device will only facilitate outputting Atmos if you use Dolby MAT to output it as metadata acompanying multichannel PCM data. You cannot currently get Atmos via the Apple TV app on an LG TV and the only way to access such audio would be via the Apple TV device. How are you conveying multichannel PCM via ARC? It cannot convey more than just 2 channels of PCM data. The Apple TV doesn't bitstream DD+ inclusive of the Atmos metadata though and uses Dolby MAT. You do not need eARC for Netflix or Amazon Prime because you can access these via the apps onboard the TV and they both allow the DD+ audio the content is encoded with to be bitstreamed to an external AV receiver or soundbar via conventional ARC. Apple provided access to Atmos encoded content via their service prior to the app being launched on the LG platform so why only address the ability to access it so late in the day? The fact that LG and Apple are making it possible to gain access to Atmos via the app shouldn't even be a news item, the feature should have been included to start with. Surely anyone developing a streaming service and app would or should be making this possible from day one even if not actually carrying such audio yet? Similar issues are apparent with the BBC's iPlayer which cannot even handle anything more than 2 channel stereo and would require the developers to scrap its current app build and rebuild it from scratch as well as rethink ythe entire iPlayer service's infrastructure in order for users to get access to DD 5.1.Īre all these developers living in a bubble on another planet and why are they being what appears to be purposefully difficult? What is the issue that causes this to be such a difficult thing to implement? I've devices that predate Atmos that have no issue bitstreaming DD+ inclusive of Atmos metadata. The same is true of Netflix and the way in which they made Atmos available to some TV apps and not others. It isn't rocket science and needs no research or development to make it work. Things like this should have been addressed by Apple prior to their initial launch of the app. It appears that Apple are having to rework their app in ordr to allow it to access DD+ inclusive of the Atmos metadata in order for the TV to then be able to output it. So why is any additional support required if the Apple app is simply using DD+ in order to facilitate Atmos? All the TV would need to do it bitstream the associated DD+ encoded audio that is inclusive of the Atmos metadata.
