ZapperBox ATSC 3.0 Tuner with DVR

The ability to decertify certificates has been part of DRM for probably over 10 years. It’s just more sophisticated with A3SA.

DVR slated for late June.

Snce most of the large broadcasters have been slowly turning on encryption let me know when zapperbox has that working.

It apparently is in Tampa trying to find out if Orlando is using same, say now they are now working to finish testing and certification.

Encryption doesn’t appear on the next 4 zapperbox releases.

Good video from Tyler regarding ATSC 3.0 DRM. Tablo is mentioned a few times…


He addressed pretty much the same concerns I’ve had all along.

With ATSC 3.0 and encryption the genie is already out of the bottle.

And the FCC has formed a committee with NAB to come up with a plan for the transition of ATSC 1.0 stations to ATSC 3.0.

Tablo needs to speak up more about it’s ATSC 3.0 plans

9/25 Release Notes | Zapperbox - ZapperBox

Per those release notes,

v2.2 release will not support recording and playback of secure content, that is planned for v2.3.

v2.3 DVR with Content Security (October)

Content security without an Internet connection (unconnected mode) will be supported around December 2023

So, recording of secure content is still only promises at this point.

My thoughts on this, they’ll be pushing back. The only way the NextgenTV (today) folks would allow for this is if the content can be restricted somehow. Much like most of the Linux world, if there seems to be a “way” to remote play or extract something that has DRM, they won’t certify (allow) it at all.

I’m am curious to see what happens.

This and I don’t trust them. I don’t trust Silicon Dust to fully deliver either. I need to see at least one company deliver DVR of DRM content and decoding without an internet connection before I start buying what they’re selling.
