ATSC 3.0 Support

Looks like ATSC 3.0 may end up being crippled due to Encryption + DRM. Some stations in various cities are already employing this. Currently the HDHR hardware and native HDHomeRun App will not even lock signal on ATSC 3.0 stations that have it! With the latest firmware they will just display "Content protection required".
Silicondust states that they have the Encryption/DRM license and are working on a solution to actually play and record these channels within their native HDHomeRun App (windows10, android, roku, etc).
Unfortunately, just like cablecard Premium channels, no opensource app has ever achieved playback of DRM content. However, most opensource apps including JRiver can play cablecard Encrypted channels (without copy protection).
PLEASE look into getting JRiver licensed for ATSC 3.0 Encryption. If you don't, when the USA shuts off ATSC 1.0 everyone will be forced to use the HDHR App!

AC-4 has this peculiar thing that audio uses very obscure sample rates and you are supposed to resample it to a common rate as needed. But the decoder does not do that yet and would rely on Media Center to do that instead.
The easiest setting would be to set both 44.1 and 48k to resample to 44.1 and 48k respectively in output format. This wont cause resampling for any normal audio, but will resample the oddball AC-4 files.
I might look into doing that transparently.

Changed: Audio with odd sample rates will be automatically resampled to a common rate.
This seems to have adversely affected bitstreaming (non-ATSC 3.0) tv channels/recorded shows my Denon! I get intermittent crazy loud "buzzing" noise. It's happened four times so far. It will usually go away if I press STOP, then Play again. I've set resampling back to NONE, to see if it goes away. Link for recording of the noise I get:

Almost all channels I looked at have 384kHz, there's one that has 448kHz but that is not in the MC re-sample list at all ?
Hendrik:
Bitstreaming completely bypasses any resampling logic. If your channels show weird sample rates, something else is up. Although those sounds more like values for the audio bitrate.

Before today, I've never looked at bitrates. I only care about why I am getting a crazy loud buzz noise sometimes. It's NEVER happened before, years and years of bitstreaming through three different AVR's. Aside from turning bitstreaming off, what should I do about this?

Nickk @SiliconDust says:
"It should be possible for in-home third party apps to meet requirements similar to how our apps meet requirements. It requires work but we are happy to advise."
Looks like ATSC 3.0 encryption may be closer to CableCard than we first thought. It would be great if someone from JRiver staff could reach out to Nickk on this. The sooner the better!
