Encryption

While I generally agree with what you are saying here I would beg to differ on one use case I.e. sports. Fox Sports upscaled 1080p in HDR is spectacular on my LG C6 OLED. I would be tickled pink to be able to get all my sports in this format going forward…

OLED makes a big difference - it has a lot more headroom to work with.

it also has the technology to handle gamut bending.

HDR ought to help with a particular thing that bothers me, when you're watching a football game being played in the late afternoon when there is a mix of direct sunlight and shadow on the field and the ball goes from one to the other and you can't see anything that is happening until the camera's exposure gets adjusted. And yes, most of that improvement has to come at the camera level rather than the display level, but once display and distribution support HDR, there's incentive to upgrade the cameras.

Personally I am not a fan of HDR - it seems to have a big downside with little benefit.

Operating in SDR mode will never be worse than HDR mode for content with normal range brightness and is often better than HDR mode for content with normal range brightness (ie most content).

1) There is no difference in black between SDR and HDR. However good or bad your TV is at displaying black that is black, HDR doesn't change that.
2) How bright your screen can go is determined by the panel - HDR vs SDR doesn't change that.
3) You set the brightness of the screen. If you set the brightness to 100% then the brightness is not far off the TV can do, or if less than 100% you are choosing the brightness.
4) HDR allows unusual content to push the brightness beyond the brightness setting you chose (this is the only benefit). Are you sure you want that?
5) This big problem - there is only so much headroom for brightness beyond the level you set (little if you set 100%) so the TV has to apply a response curve that dulls down brighter colors in the normal brightness range to reduce color banding on the off-chance over-bright content might occur. This messes with the normal-range colors even if nothing is over-bright! And you will likely still see color banding (it is a trade-off between the two).

I would much rather have 10-bit SDR than HDR.
If you really really want a wider color space than Rec.709 use Rec.2020.

The largest problem with hdr is having 2 standards... dolby and hdr10. actually its almost 3 standards as all HDR tvs can do hdr10, but some cant do dolby and some also cant do hdr10+...
HDR IS worth it for movies and you have a tv that does good HDR like OLED. Even my 2018 LG 65 inch looks fantastic and it doesnt get nearly as bright as new oleds. the blacks and highlights are fantastic.
The othjer Huge problem is too many people have cheap HDR lcd tvs that dont have proper local dimming. 10 zones is not enough need over 1000 zones to do hdr properly with an lcd. Even then HDR is still better on oled.

Any news from Silicon Dust on the issue of Encryption?

Broadcasters are required to carry at least one MPEG2 channel in at least 480i resolution with synchronized audio. AFAIK there is no requirement as to which service that be. I'm not aware of any direct prohibition on carrying a major network affiliation in AVC, but it might not go over so well if there was severe weather or some sort of emergency and some viewers weren't able to access the news on a channel where they would normally expect to find it.

Perhaps no direct FCC prohibition (although I would not be surprised if some variants of the FCC decided to intervene), but the contracts between the stations and the networks are not going to allow the local station to remove the ability for viewers to see network content (unless, of course, the station owner wants to stop being an affiliate (which have gone so well for the few station owners that did not comply with network demands regarding preemption and ownership and are no longer affiliates)). The current contracts are under NDA (so no one who actually knows can respond definitively), but the network lawyers are not stupid, and have added more and more requirements on their affiliates over the years (and we know that from when one of the stations gets threatened/sued for trying to thread the needle and not do what is in the contract we can't actually see).

The 2 CHSN channels broadcast OTA in Chicago have reportedly been downgraded from 1080i AVC to 720p MPEG2. So much for that great experiment.

the cows who in repeating fashion chew their food is always thinking the people on the other side of the wall is stupid and they stride to treat the general public that way, when know full well the general public most of which are bright and have their ducks in a row... so for the broadcasters to cling to that out-molded mindset is a waste of time and money on both the sender of the signal and the receiver of the content. happy new year to all, the users on this forum and the moderators that make it run, again happy new year.

Happy 2025, everyone! I'm looking forward to seeing what the new year brings for the ever-changing technical and legal landscape of ATSC 3.0.

A3SA canceled their meeting? Sounds like they are ducking you.

Might need to go on hidden camera and just show up.

This is getting absolutely ridiculous not on Silicon Dust but this whole thing with DRM. I used to get a whopping 2 channels ABC and FOX in the Philadelphia area for ATSC 3.0 and now I'm down to 1 as FOX is now DRM as well. Must have happened sometime last week. Just ridiculous.

Huh that article was from Feb 2024, where Ron Wheeler, the managing director of A3SA said "For the past year, we’ve been working in consultation with several electronics companies who are developing devices designed to add new features for NEXTGEN TV viewers, from simple DVRs to more advanced home networking systems. After considering the various home scenarios, A3SA is pleased to release detailed specifications that will guide companies and soon provide consumers with a wealth of new options for digital video recording and more...”

So in Feb 2024 Mr. Ron Wheeler supposedly "release(d) detailed specifications" that would allow "...HDHomeRun ... build DVRs for ATSC 3.0 that support the new DRM standard... let(ting) them stream OTA TV channels ... on common media consumption platforms such as Android, Fire, Roku, WebOS, and Tizen, with iOS support in process..."

I'm in Tampa, and we also have a Fox O&O here. We lost ours some time last month, so I guess they're flipping them all. That brings my number of watchable ATSC3 channels, to zero.

Absolutely ridiculous.
