Why not 1080p?

[mardek1995 200]

I was checking the resolutions on the newscasts on the big 4 affiliates (and KDAF as well), and they were all at either 1080i or 720p (Fox 4 at 720p, the other big 4 affiliates and KDAF at 1080i), not even at 1080p let alone 1440p or even 2160p. This isnt just newscasts, but it seems most ota content is still at either 720p or 1080i. When will they upgrade their signals to 1080p? Does the spectrum auction hold that answer?

I don't think the spectrum they will be left with is enough for 1080P and multi casting at the same time. 1080i and 720p are good enough. Maybe they can go to 1080p on cable, that would be a selling point.

I guess that's another reason why cord cutting is increasing. TV is just going to be beaten by the internet, first cable will go, then OTA tv as we know it.

When the ATSC standards were developed, 1080p wasn't fully developed and was "too advanced". As a result the frame rates for 1080p in the ATSC standard are sub-par (29.97fps max vs 720p 59.94fps)

 

ATSC 3.0 is specced with support for 1080p 59.94 (and higher) but that is a good decade from happening at the least. You're more likely to see 4K resolutions being broadcast OTA than 1080p, really.

Additionally, 1080p has a higher degree of overhead when transported over a network as the compression encoding is not as dense at 1080i because of the reasons that Weeters stated above.

Speaking of 1080p and 4K, there's more content in those resolutions on the internet (Netflix, YouTube, etc.) than there is on cable or even OTA.

Yes, additionally facilities may not be designed for it. 1080p requires 3G-SDI where as 1080i requires HD-SDI (which is half). Stations when they transitioned to HD newscasts or turned on their digital signal knew the limitations of the current broadcast standard and may not have sprung for equipment or wiring in 3G.

 

WRAL is testing ATSC 3.0 with an upscaled 1080p feed and a looped 4K feed.

ABC is 720p. I know there were a handful of Hearst affiliates that upscaled the programming to 1080i in the beginning but have transitioned back to 720p.

While WRAL is testing a 1080p feed and a looped 4K feed, Netflix already has 4K content and youtube has videos in 1080p at 60fps.

I was actually talking about newscasts, but yeah, ABC's programming is in 720p, and I'm willing to bet that sports are in that same resolution.

That's because YouTube and Netflix are using different compression standards which currently are incompatible with the current broadcast standards.

Computers and servers can easily accept new codecs and formats that allow for the use of more efficient video compression. Your TV/OTA receiver is very specifically built and programmed to decode an ATSC signal that has been transmitted from a transmitter specifically designed to transmit an ATSC signal.

 

You won't see 1080p 59.94 or higher until the next "DTV Transition" to ATSC 3.0.

Isn't it also easier to compress and encode something more efficiently that is a known size rather than one that's ongoing?

Pay Per View has 1080p and 4k. in fact cable stations by fox and Disney/ABC are 720p However i could see HBO doing 1080p but not any means or anytime soon.

Let's not forget that LiveU and TVU packs bind cellular signals together for uplink to station. While they can stream 4G LTE to stations, I find that use unlikely because of the need to down-convert the bit stream into something more compatible with 1080i (HD-SDI) broadcast.

Depends on the TV provider. AFAIK, only DirecTV is doing 4k broadcasts of ANYTHING (PPV, live sports, etc) I'm sure that will change when the TV providers make upgrades to the systems and bring 4K channels to the air.

It's not gonna happen anytime soon. Period.

Maybe in a few years, if not any sooner, it might

I remember when they were first promoting HD televisions, they said watching TV in HD would be just like looking outside your window. Although HD doesn't come anything close to that in general, it is still very satisfying to the eyes. (I find that digitized film looks a lot better on an HD set than anything captured in HD video.)

 

About 10 or 15 years ago, long before 4k, I saw a display at Circuit City featuring a Sony HD television and demo video featuring some city in Spain. It was shot in HD, and it was shot in video as opposed to film. That is the only time I have ever seen a video that truly looked like I was looking outside my window.

 

What is it that Sony did to make that demo and why aren't these techniques used more often in TV production today?

 

To me, most HD video looks like crap.

Is your TV calibrated?

I would guess that the display you saw was displaying content captured digitally in 1080p and played out in 1080p on a calibrated monitor. I imagine back then most content was captured and edited in film.

i'm assuming because of the MPEG Artifacts that HD signals bring in.
