I hear a lot about this but there are two things that must happen before this goal can be realized:

1. ATSC 3.0 must be approved by the FCC for everyday use. It is currently in the grinder and it appears that the new FCC chairman is all over it.

2. Tuners must be available. Maybe they're waiting to see what all shakes out in the UHD feature set or maybe they're waiting for the FCC call.

If ATSC 3.0 is approved, it seems like mainstream broadcasts are quite a way off (more than five years) and by the time they're ready to deploy, they're going to be up against the repack in a most painful way. I think it is imperative that they get ATSC 3.0 going *NOW* so they don't have to try to squeeze both DTV and ATSC 3.0 into the post-repack 35 RF channels.

I see the industry announcing 8k tvs within three years. So they won't even be ready to do 4K ota broadcasting by then?

Sorry, but I can't imagine "8K" being of any value whatsoever in the home. I think it a bridge too far, and it will fail worse than 3D in the home and Smell-O-Vision.

All the stores are having sales on 4K TVs for the Super Bowl. FOX is not doing the game in 4K. When an event as large as the Super Bowl is not in 4K, one has to wonder about the viability of the technology for widespread usage.

But you do know that they will offer it in a few years right? I mean the whole electronics industry depends on consumers buying the next big thing. We had black and white tvs in the 50s to middle 60s and then color tv came out in the mid to late 60s. Then we had stereo tv in the mid 80s, followed by progressive 480p on dvd players in the 90s. Vcrs came out in the late 70s with wide acceptance by mid 80s. Then in 99 we got dvrs . Then in early 2000s we got our first HD tvs, followed by mandatory digital transition in 2010. Now we have 4k tv all the rage in the mid teens followed by of course, 8k bringing up the rear. I say early 8k in three years and full on sales of nothing but 8k by mid 2020s. It just follows the pattern of the tv industry.

I don't think so, this time. There will be no perceptible difference in the home.

Until we get widespread 4K broadcast it will not matter. I've been reading that the likes of ESPN 4K is just around the corner. Problem is that corner has to be a mile long because it's going on 3 years for that rumor.
You can bet tv manufacturers will target the non educated on tvs as they always do to boost sales with 8k just like they did with 4K from 720p or 1080i.
But something's don't change no matter what type of tv you are watching.
Garbage in equals garbage out.

IMHO a big problem with ESPN 3D was it was a separate production for some sports like football, increasing expenses. But with 4K they can just downrez the 4K production so they don't have that cost to deal with.

Exactly, the "4K" camera shoots everything... A lot of 4K is shot in 2.8k and scaled, some is 3.4k, some 6k, its all over and tons of options, and all can be downrezz'd

I've said it before, don't hold your breath for 4K OTA. Just because somebody demoed it doesn't mean it will go live. First, if broadcasters won't opt in to full 1080 HD but rather save bandwidth with 720 what makes anyone think they're now going to jump on the 4K bandwagon? Ain't gonna happen. Second, the purpose of 3.0 is to compress bandwidth (repack), 4K OTA expands bandwidth, so which one do you think wins out? Yes, 3.0 could provide 4K and 5.1 audio but that is not why it's being implemented. Bottom line, it's being implemented to facilitate the repack, pure and simple, so put away your pipe dreams. Oh, yeah, one more thing, ESPN doing 4K is irrelevant, they are not a broadcaster, they are cable/satellite bound.

Until and if its mandated in the foreseeable future OTA 4K alphabet TV network COO and affiliates and independent broadcast will probably be optional when the ATSC 3.0 embedded tuners are widely adapted in the TV's and maybe HDMI /USB ATSC 3.0 RF tuners .

AFAIK you can't multiplex ATSC 3.0 UHD 4K and HDTV /480i on the same RF TV transmitters and those things ain't cheap at market scale and neither is the electrical current and so on at that scale and they probably can't give away the analog scan line VHF transmitters now in the developed world so that may translate to the ones thay have now since new 1080p TV's are vanishing at scale now .

"4K content for the consumer market today gets delivered to viewers via streaming internet connections with bandwidth of at least 15Mbps or more. This is widely expected to be the vehicle by which the future of 4K broadcasting will move forward."

If we were talking about analog video at UHD resolutions, maybe. Since data is data, there's no reason that an old transmitter won't send the latest and greatest data. The trick is using a data scheme that allows you to pack all that information into the channel bandwidth and that happens back at the station; the transmitter just forwards a bitstream.

re:
Maybe I'm uninformed but I read on more than one occasion from what I believed to be credible web sites that ATSC 2.0 Digital broadcasting and ATSC 3.0 UHD up to HDR 10 HLG can not coexist on the current HDTV RF transmitters which would likely have finite bandwidth limits like any digital device or like common copper coax. cables like RG 59 vs RG6 .
