Some U.S. Broadcasters To Roll Out "Next-Gen TV" By 2021

I'd long heard about ATSC 3.0 and 4K TV, but I admit I don't know a lot about it. This article talks about how over-the-air TV broadcasters in some of the biggest markets in the U.S. are experimenting with the next generation of TV (didn't we just get HDTV?) 

According to the piece, the new technology has "the ability to get an over-the-air TV signal on a cellphone without using a cellular service or data plans, as well as 4K, HDR and an emergency warning system." 

Which is why I'm sure Rogers and Bell will never allow it to happen in this country. Receiving a TV signal you don't have to pay for on your cell phone? Why that's sacrilege!

Nonetheless it's coming.

I've never seen 4K TV, although while some sets are out now, there's not much to be seen on them.

Is it really that much better than HD? Just how much fine detail can the human eye make out anyway? And if it were to become the new standard (the article claims it's voluntary for stations to test if they wish at the moment) does that mean we'd need yet another TV or could you continue to watch in the old, drab HD that we were all told was the latest and the greatest before there was something later and greater?

At some point, they'll just put a chip in our heads and be done with it. 

Although someone will doubtlessly come out with a better head.

Transmitter and IRD manufacturers have been pushing the opportunity for US broadcasters to plan and implement the NextGen technology for ATSC 3.0 / OTT during the current spectrum repack.

Some stations which will have their RF assignment moved , will potentially be in a situation where they will need a new antenna, and re-work on the transmitter.  The manufacturers like Gates (formerly Harris) are saying this is an ideal time / opportunity to make the investment in the transmitter plant.

Canadian broadcasters never pursued the feature of sub-channels in ATSC 1.0 (well Global did for a letterbox feed to the analog Tx sites). In the States, two or three sub-channels are the norm on each main channel.

In ATSC 3.0,  a broadcaster can originate a UHD signal, or 6 HD signals, and a number of SD subs on the main channel. 

The streaming capability of ATSC 3.0 is said to rival, if not surpass, the capability of the pending 5G wireless platform...

By the time 4K becomes all that important, 8K will be the in thing to have. 
The real question is, (as some Televisions keep getting larger and larger)
What will the movie theatres do??? 
They should be pushing 8K right now while the price is still too high for home use.

Based on an admittedly rudimentary understanding of ATSC 3.0, it should be resolution agnostic. Not unlike a modern web browser, an ATSC 3.0 capable TV should be able to adjust to different resolutions. If the ATSC 3.0 stream resolution is higher than the native resolution of the TV's display technology, the video processor in the TV should down-res the content.

Totally agree. They (Bell and Rogers) have the added disincentive of being the two largest BDUs in the country. Rhetorical question: How the hell did we get to such an absurd telecom/broadcast ownership structure in this country? How could we let this happen?

A viewer has to be really close to the display to see a difference. So close that it's rarely practical in a real life situation.

On the production/post production side, however, 4K is wonderful. With all those pixels you can digitally pan and scan without any perceptible deterioration in quality - assuming the end product is rendered in HD.

The real excitement around next generation TV isn't the resolution (e.g.: 4K, 6K, 8K etc.), it's support for High Dynamic Range and wider colour gamut.
