Are the recordings from ATSC 3.0 encrypted? It would seem that if they are not, media servers like Plex should be able to handle the recordings like any other video. Is this correct or am I missing something?
It just occurred to me, I'm also wandering if the HDMI output is not encrypted, it would seem logical it's because if it were tv's that do not have atsc 3.0 would not be able to display the signal. So that makes me wander if all you have to do is send the signal via the hemi to a video capture device which would record the video in standard mpg format then media servers like Plex could then distribute that through a home network.
Any thoughts? Has anybody tried?

Re: Are ATSC 3.0 recordings DRM encrypted
For this forum that is all moot as the hdhr 4k's do not currently work with drm.
One of the purposes of drm is to prevent such distribution as everything is supposed to ensure what it hands off to will also ensure such. However one of the delays in releasing some boxes was caused by the first box to handle drm not requiring hdcp but again since that requires equipment (both capture and tuner) that doesn't use SD equipment it isn't really a topic for SD's forum.

Re: Are ATSC 3.0 recordings DRM encrypted
The technical answer to your question is "not always." I have ATSC 3.0 recordings made by my Flex4K that aren't encrypted...that's because the channel itself (at the time of the recording) did not DRM encrypt the recording. I don't use Plex so I don't know if it will play them but what I do know is that the audio (AC-4) is either (1) played directly on my LG OLED if I use that device for playback, or (2) transcoded by the SiliconDust hosted transcode service if I play back the recording on any other device (e.g. iPad).

They are not like any another "video" because of the AC-4 audio so even without DRM there will be difficulties.Tom Moats wrote: Mon Apr 28, 2025 7:03 am Are the recordings from ATSC 3.0 encrypted?

Re: Are ATSC 3.0 recordings DRM encrypted
sorry, from the title I was thinking more about for stations that are marked as DRM. Obviously if it isn't DRM it will allow such recordings.
The issue with plex and most other things is the ac4 audio not the video (unless DRM).
Again when it comes to recording that through hdmi, that isn't really a topic for this forum as SD has no such capture device. It would be far easier to just transcode the audio in the ts (probably what you were meaning as standard mpg format) that the hdhomerun "outputs" but that will require some 3rd party tools to do such. If for some reason your viewing device doesn't support hevc (h.265) video in a ts, you would also probably transcode that to h.264. Some devices also don't handle a ts file when it has a mpg extension, some also only do so when served and not played directly from a file.
