Dolby MAT is basically multi-channel PCM plus Atmos object data. Apple TV 4K is practically the only device use it because Apple refuses to support any pass-through. Support of Dolby MAT has nothing to do with support of AC-4. Two are unrelated. I'm pretty sure Apple TV 4K does not support AC-4 at a...

The ONN can handle 4K HEVC without problem. So, these 1080p HEVC is piece of a cake. However, it is not capable of handling AC-4 audio. It must be your Emby server does the conversion. Typically, ATSC 3.0 station only broadcasting 5.1 audio so far.

Hence, if you have an AVR connected, you can tell if you are receiving 2.0 or 5.1 audio to determine if your device supports AC-4 or not, assuming your local station broadcasts 5.1 all the time.

No, not at all. The video at HDMI is fully decoded and decompressed display data which is not the same thing as the broadcast transport stream which for ATSC 3.0 is H.265 compressed. A typical ATSC 3.0 station in my area has a bit rate of around 4 to 5 Mbps. An 1080p display stream from HDMI is arou...

It is much higher bandwidth data stream that must be recompressed down in order to re-disttibute.

It doesn't really matter much though (a single tuner STB). If you pay attention, no one has DVR certified for DRM yet. The earliest estimate published is sometime in Oct 2023. HDHomerun tuners have a lot in common with those DVR products. And has nothing in common with those single tuner STBs. Broad...

From what I know, cloud transcoding only generates 2.0 audio, not 5.1

Nothing more seamless than using built-in DVR on the Flex 4K itself.

Make sure your PC has internet connection or if you use 3rd party firewall. don't block the cloud transcoding of AC-4 built into the app. Most PCs can't handle AC-4 directly. Hence it needs to send AC-4 audio to SD's cloud transcoding server convert it back to 2-ch stereor audio for playback. If HDH...

Thanks. That means I have 3 different devices that can handle AC-4 and could save SD some cloud transcoding costs

Thanks again.

Just launched the T-Vision Hub v2 device again at 2:08PM EDT. Not sure if this time the information is sent.

Thanks for confirming that.

I did another test this morning:
7:05AM Sony X900H
7:15AM T-Vision Hub v2 (from T-Mobile).

Hopefully this time the diagnostic info is sent successfully.

Is there anyway I can tell if my device is handling AC-4 directly or being transcoded? If you really want to know, you can probably turn on flow instrumentation on better routers to see the traffic metrics. If your router does not have that capability, you could probably use a brute force approach ...

While waiting for confirmations, I did some testing using the recorded ts file from DVR. I confirmed that my ts file contains following: * 1080p HEVC video * AC-4 5.1 main audio * AC-4 2.0 secondary audio Use Just (Video) Player app play this file on my various Android TV devices, here are what I fo...

Thanks. Just updated my profile with new device ID of Flex 4K. 11:19PM (EDT): Sony X900H 11:24PM: Rocktek G2 This morning, tested all different audio setting on Android TV OS of G2 (Bitstream, Auto, Dolby dd and Dolby dddp. The last two options just showed after a new firmware update upgrade. No ide...
