More info on the status of DRM on SD devices....

Should any of this be a surprise to anyone? The sole purpose of ATSC-3 is to lock down OTA broadcast TV and enforce a 1950's-1960's model of TV viewing -- live viewing on their terms, no time-shifting, no commercial skipping.
The only way this will end up being acceptable to consumers/taxpayers is the FCC laying down the law to the media cartel.

Cant seem to get anywhere more on SD forms, as usual, they just delete your posts and say Read the rules... .which list 7 very brief things that mean nothing to any context of removal....
Their posts say they waiting for A3SA servers to be fixed, so their products will get the certificate...been waiting for 7 months. That seems like they are just sitting around, waiting for progress update.... i post, "How often are you contacting them to get issues resolved?"
I would be hounding them every day for something this simple and ridiculous that is preventing a product feature launch, costing my company time and money.
[removed by moderator -read form rules] every time.
Meanwhile,. other manufactures have their STB working, and that same company, their Gateway device too. But SD, seems to be dead in the water.

SD claims that DRM support requires updates and thigns in BOTH the player app software, and the OS of the device playing back the DRM stream.
Well, ok, so devices like the Tivo Stream 4K, since it get no more updates, is out.
Nvidia Shields, also out, since Nvidia/Google seem to have forgotten about updating them for quite some time.
Apple, will take forever to implement it, and update tvOS too....
So, not sure, even when SD does eventually get things worked out, what devices will even support playback of the DRM stations.
More anti-consumer moves to eliminate one venue of media consumption.
Not surprised though.

What other gateway device has ATSC 3.0 working with DRM support? What other gateway device even has an ATSC 3.0 tuner?
As to the Tivo Stream 4k and Nvidia Shield, both of those devices have Widevine, which is what is needed from the OS to support decryption. So they may work.

A user on AVS form local to my market reports firmware update allows watching the DRM protected station here.

Having purchased a SD Homerun 4k Plex Dev Unit I can now comment on the technicalities of an "unofficial" theoretical bypass of DRM on ATSC 3.0.
All A3 video transmissions are glorified DASH streams nearly identical to streaming services (think .mpd manifests). So all the video you are seeing is actually just very short video segments being merged and played back together in real time in a packetized fashion.
Now for the fun part :3
The HR Plex 4k Dev unit allows for direct output of the data received from the RF transmission of ATSC 3.0 signals. I have not yet experimented with the PCAP captures but the DASH TAR output seems to have proven very fruitful to say the least.
Here's the bombshell! The metadata containing multiple values for a key request are all in plain text and included in the RF transmission! It is in a file labeled "manifest.xml".
This file contains the PSSH, Key ID and License URL among other general metadata on what is being broadcast.
The only thing that would be needed from my understanding is that a L1 cdm file would be required to use in conjugation with said values, although I know someone experimenting using a L3 cmd file.
Feel free to message me if anyone wants the .xml file to mess with themselves ;3.
For your info and to all Silicondust still does not work on ATSC 3.0 DRM and Cable DRM is crippled on most devices that use Android.
And I am getting the feeling that this will go the way of CableTV DRM recording which never happened.
