COVID-19 Delays, Not Derails, NextGen TV Plans


Las Vegas and Portland, Ore. will light up their NextGen TV markets in June from their initially-slated late April launch, but the broadcasters and coalition driving the new industry standard forward say major launches will still move ahead this year. The launches will coincide with the arrival in retail stores of the first 3.0-capable sets.

Channel Stacking
While new deals are required for stations to broadcast network programming in 3.0, the far thornier issue has been figuring out where to move 1.0 programming in order to free up capacity on host stations to launch 3.0. Local stations have also had to convince the networks that such “channel stacking” won’t have a negative impact on picture quality, though 3.0 insiders say the networks are being flexible.

“Everybody’s in a learning mode, especially with things like football,” Fritz says. “Fox, NBC and CBS want to ensure that the quality of sports programming is not diminished. So we’re showing them what the picture quality is going to look like with the new encoders, whether it’s doing one HD and six SDs or two HDs and four SDs.”

Hane agrees: “The networks understand we’re going to be stacking up HDs, and they’re fine with that.”

As for the early 3.0 broadcasts, they will initially just be simulcasts of existing 720p and 1080i HD network programming. In Portland, KRCW will broadcast its own CW feed as well as CBS from KOIN, ABC from KATU and PBS from KOPB, while KPDX will broadcast MyNetworkTV as well as Fox from KPTV, NBC from KGW and PBS Encore from KOPB (the hosting of KOPB content is still awaiting final signoff). With a proposed modulation/coding scheme that will deliver 25 Mbps from each host 3.0 station, each commercial HD feed will initially be allocated around 7 Mbps while the PBS feeds will get around 3.6 Mbps, all using HEVC encoding.

Of course PQ will be hurt. But maybe some folks like that idea, if it sends a few folks onto their streaming system, with higher PQ.

If other frequencies are available, they should use them, rather than take the cheap and easy stacking method. And I’d make the ATSC 3 stations use the new RF until the ATSC 1 stations sunset. Disturb the public the least.
 
NextGen TV Receivers Not Ready for Consumers


While TV sets will hit retail floors soon, low-cost gear for the masses is still elusive
They better be by next year as we'll have a few more test markets coming on

I think they need a good reasonably priced DVR with at least two ATSC 3 tuners and preferably, also a couple of ATSC 1 tuners. Our next year. Not gonna be much interest this year anyway.

Looks like history is repeating itself again since USDTV whatever that was called back then.

So called OTA pay TV service was a total flop.:p
It's basically a modern version of non-cable pay TV. Just think of SelecTV, OnTV, etc. but with today's technology, with the pay channels being unlockable pay subchannels of your local ABC, NBC, CBS, FOX, CW or MyNetworkTV affiliates offering premium program options, such as sports or movies...

Well, had that one in Albuquerque's TV market.

USDTV, which started in Salt lake city and few other TV markets and that business model they had at the time lasted barely a 4 years.

They uesed MPEG-2 and MPEG-4 for the most part.

It was used on my 4 local stations KOAT-DT, KRQE-DT KWBQ-DT and KASY-DT at that time.

Just the same thing in ATSC 1.0 in the past and for future ATSC 3.0.

No difference, except for better video codecs on ATSC 3.0.:)

Just go to Wikipedia and type USDTV. :hatsoff
