**** Media Center/CoreELEC does legitimately support Widevine for certain streams that use it. That being the case, wouldn't it likely be able to play/display enctrypted ATSC3 streams?

I don't know the ins and outs of how Widevine works but it seems that this should be possible. Being able to record and play a video back later (on or using the same serialized device) is another matter but is this likely to work?

I'm guessing that ATSC 3 isn't going to go very far until/unless they relax some of these restrictions or reasonable accommodations can be made.


*Note to forum moderators - I had to space out the spelling for **** in order to get it to display, this is a perfectly legitimate media center which does not condone piracy but 3rd parties make pirate add-ons available for it. This has nothing to do with the media center software itself, in fact they took legal action against some of the 3rd parties illegally using their name to sell pirate boxes. You should update and correct your content-filtering.

No, Widevine support is not enough for A3SA. The app itself has to be secure and A3SA has to approve the app.

Dunno if the mods will get back to you. But I think they block all references to any product that is even remotely competitive to SiliconDust products. I'd guess that they just don't want SD forum content appearing when someone does a google search about another product. Nothing to do with piracy, just competitive marketing defense.

I think it's a mistake. HDHomeRun tuners can be used with it so it should be fair game. Silicondust even had an official HDHomeRun addon for that platform, and there was a forum dedicated to it in the third party software section here.

Years ago some dodgy Chinese companies started making unnamed boxes that shipped with the **** media player pre-installed as well as third party plugins that provided instant access to pirated content. Because these boxes were unnamed and they launched into **** they became known as **** boxes even though the boxes and the piracy aspect had nothing to do with the open source **** media player project.

Major shopping sites block/ban media player products that mention **** and in the past shopping sites have sometimes blocked/banned our product for saying it works with **** even though the HDHomeRun is not a player device and doesn't run ****.

Here is a rather direct question for SD.

I have used your hardware and software for years and contine to do so.

However owners of your 4K tuners are unable to record any programming in 4K or even view programing.
No progress appears to being made to change this, so why bother selling 4K capable SD hardware?

Even if the A3SA approved DRM decoding today, no one is using ATSC 3.0 to broadcast in 4K.

Not all ATSC 3.0 channels have DRM protection. Like for the most part the ABC O&Os, Sinclair, Nexstar and PBS are in the clear. At last check only one FOX O&O is using DRM.
In Philly it has a big advantage as their ABC O&O WPVI is stuck on VHF-lo 6 for ATSC 1.0, while their ATSC 3.0 channel is in the clear on UHF 33.

The Oklahoma City market was among the very first group to launch ATSC 3.0 and also among the very first group where encryption was introduced. The CBS affiliate, KWTV, locally-owned by Griffin Communications, has never offered an ATSC 3.0 signal. The only station among the five who are broadcasting an ATSC 3.0 signal that is broadcasting an in the clear is the Fox station. And of course, none of the ATSC 1.0 stations are receivable at my location at all while the ATSC 3.0 Fox station is rock-solid. So essentially I use my HD HomeRun tuner to receive only ONE station. I rarely ever watch Fox, so the tuner does not get much use at all.

Which is why I asked a while back why the HD Homerun could not be modified so it could at least tune and receive encrypted ATSC 3.0 stations so they could be at least viewed on the TV but not record them until the legal stuff is resolved. Seems like an easy change to me.

Making that change would be a big plus and I know I would buy one. Maybe many others too.

You have a misunderstanding of the situation.

A3SA does not allow an ATSC 3.0 television to decrypt content delivered via a network tuner.

Which is why a while back SD created this thread — I suggest you read the first post here: viewtopic.php?t=78888&sid=abcf06f928a9a ... ad4f2f71a2

OK, let me see if I can get the problem with encryption of ATSC 3.0 signals straight in my feeble little mind. I read the referenced thread and came up my hypothesis: The problem that A3SA will never do anything about is allowing a networked tuner to decrypt the signal so that that signal may be watched on several different devices, within a home, at the same time. This will never be allowed, right?

So, in my mind, my question is what is the difference between one of those networked tuners sending a signal that various devices can use and an antenna that is connected to a splitter that sends its signal to various TV's so they can display the signal? Is an antenna connected to a splitter OK because that signal is only viewable on TV sets, while a networked tuner's signal is not OK because it can be viewed on TV sets, tablets, and phones?

I just do not get the difference, so hopefully someone can enlighten me and explain the apparent lack of logic in all this.

I don't think this is correct. From reading the actual source documents from the various organizations, there would appear to be a current set of implementations that could allow this. However, it would require SiliconDust to substantially change their architecture to implement all those requirements. They really don't want to throw the entire baby out, so are attempting to work with the organizations to propose and receive approval for alternatives and extensions(*). Other companies, starting from a different base, may choose other paths forward.



(*) And nothing is final until it is final. Such proposals, revisions, revisions of revisions, and approvals could take months, or years, or never happen. And SiliconDust is not likely to offer any substantive update on schedules until the fat lady is singing (as you don't talk about closed door negotiations).

So are you saying that A3SA has provided an approved architecture for network tuners to be certified and provide DRM content to various devices over the network? Or are you just talking about the one receiver connected via HDMI to a single TV solution competitors are offering?
