ATSC 3.0/NextGen TV Certification

The reason I purchased my first HDHomeRun devices was there was some type of cooperation/deal between SD and Plex. I believe Plex was the first media system that offered OTA TV and a DVR function using the HDHomeRun.

It is not rocket science to create something that can use the HD Homerun networked tuners. Personally I use MythTV which has supported it since right after it came out. I also mentioned before that the VLC app on a pc can be used to view live tv. Here is one of my channels http://hdhr-1076c03a:5004/auto/v2.3 This is to view channel 2.3 and hdhr-1076c03a:5004 is the name of the tuner in my router, the ip address can be used as well. You simply have the same thing for each channel only the v2.3 would change for the different channels and it is not very hard to create something that can pull it. Here is using wget in a terminal to download the mpeg stream to a file:
dave@asus-node1:~$ wget http://hdhr-1076c03a:5004/auto/v2.3

v2.3 is the name of the mpeg file being downloaded to my home directory.

I have a nice screenshot of this file being played in VLC after downloading as well as the window that shows all the codecs but I cannot see a way to upload an image to this forum.

Thanks for the great explanation. It now makes sense why apps like Plex and Channels needs the proper codec to be able to decode AC-4 audio. If there is a device between your network and the HDMI port on your TV like a Fire TV Stick or Cube (which I use), does it need to process the AC-4 audio of does it just pass the stream to the TV?

I am looking to purchase a new 80+" TV. My question is does the Samsung q95a tv have the ability to connect to the HDHomerun App and play back audio. There is another forum that states the Samsung TV does not allow the HDHomerun App in their app store. I know this tv has its own next gen tuner but I don't know if it has multiple tuners or just one, and I don't know what kind of OTA interface it has. Since all of my viewing will be mainly from OTA and hopefully ATSC 3.0 stations should I consider a different TV?

I couldn't pull up the specs for a Samsung q95a, so if you have the exact model number look it up on the Samsung site (they have a chat option that might be able to answer any questions you might have, or better yet go to a store that has that model and check the apps that are loaded on the TV to see if it's there. Most new TV have a network port (Cat5) so you can attach it to your home network.

There is also a thread here in the forum you might want to look at:

In HDMI Passthrough it can depend on the TV to do it but the TV has to support it. My Roku Ultra supports it and can either pass it through or convert it. I too am waiting for FFMPEG to support AC-4 of which there are rumors of having beta builds or experimental builds that support it but it my MythTV frontend needs to support it unless it can pass through the codec through my AMD RX 6700 card's HDMI 2.1.

My ZapperBox ATSC 3.0 tuner supports AC-4 and can convert it to DD DD+ etc and even PCM if I remember correctly and pass that out the HDMI or it can be set to HDMI Passthrough and let the next device decode it.

One of the problems of AC-4 may be a licensing issue and probably is not free.

Regarding Samsung TV's I am aware of the post you mentioned but in that post it indicated that the only way to get the HDHomerun app installed was to enable developer mode and then sideload the program which required using ADB debugging protocol. So again my question is to ask if Silicon Dust and Samsung have now got a working app in the Samsung app store? I know that Samsung uses TIZEN OS and not google Android OS so it might be that the HDHomerun program is not something Samsung is willing to allow in their Store. I was thinking of purchasing the QN85QN95a set but am having second thoughts purchasing it because of this issue. I believe that LG and Sony do have the approved HDHomerun app and I may end up going that way if the HDHomerun app is not supported and is just a kluge at this point. I am not really into developer options and sideloading.

My understanding it has been submitted to Samsung a long time ago and it is up to Samsung to add it in their store but keep in mind Samsung has screwed SD up in the past with apps, first was the original HDHomeRun app that was only available on the E Series... when they went to F series Samsung wouldn't allow such on that model and future models. Eventually they did switch to Tizen. In the mean time on the M series they had RUI support that even supported DRM content... It basically looked just like the HDHomeRun app (at least for live) and worked better than just about anything but then Samsung decided RUI was meant only for RVU which was for Tivo so they disabled RUI and subsequently SD also pulled RUI support. So I have strong doubts that samsung will ever have the app in their app store and if they do, I would expect that they would do the same again and pull it from being available for next years model.

LG has even stopped allowing the HDHomeRun app to install on some of their new models. Sony as Android/Google TV so that will "always" be supported.

The new model LG issue has been identified and we are working to get that approved.
