Practically everyone has 1080P screens now, most people have 4K. Why are broadcasts still showing sub 1080P resolutions?
Wikipedia said:HDTV may be transmitted in various formats:
- 720p 1280Ă—720 progressive scan: 923,600 pixels (~0.92 MP) per frame
- 1080i 1920Ă—1080 interlaced: 1,036,800 pixels (~1.04 MP) per field or 2,073,600 pixels (~2.07 MP) per frame
- 1080p 1920Ă—1080 progressive scan: not a broadcast standard for ATSC 1.0
Not only is it compressed, many stations that should be broadcast in "HD" are still in SD like Cooking Network, DIY, movie channels such as HBO/Showtime/Cinemax aside from the main channel. Plus, their Guide is a freaking joke, the channels are half hazardly thrown together in some random order that makes no sense, there is always an advertisement in the guide that takes up allot of space, so it is a nightmare to try to randomly find something to watch. I just use voice control to go to a few specific channels, sigh. I think part of the problem is they had some legacy layout in the guide and kept adding in random channels in HD and SD, when they should just throw everything out and start over and organize their freaking guide so it makes sense.Comcast is broadcasting terribly compressed on top of their bad signal
Yep. It's really bad. Of the 10 HBO channels, a whopping 2 are HD. And the signal quality is so compressed, it's like a blurry 480p at times. I almost always stream through HBO GO vs. watching anything live, especially for event programming. There are a few local broadcast channels that aren't compressed to hell - mainly prime time NFL broadcasts and that's about it. It's disgusting that they get away with it, but apparently most people don't notice. I've also seen them try and deny their differing compression is any different than others, but it's bullshit. My TWC feed when i was in NYC was literally 2x as good, minimum. When I moved, I thought I was watching SD feeds when it first came on. Oh well, no recourse.Not only is it compressed, many stations that should be broadcast in "HD" are still in SD like Cooking Network, DIY, movie channels such as HBO/Showtime/Cinemax aside from the main channel.

That's not true. They send HD signals that are compressed to yes, fit more channels in, but they are still HD. It's not like OTA signals are any different no matter what people try to say.Satallite and cable don't even send HD, they send some half-HD compressed stuff so they can fit more sports and PPV in
1080i broadcasts look better than Netflix 4k imo, low compression 1080i is pretty detailed.

they could get away with 480p and low bitrates
99% of the population can't tell the difference/don't care
this here, is why standards never improve.1080i broadcasts look better than Netflix 4k imo, low compression 1080i is pretty detailed.
Is that true? Most people have 4k sets? Damn, maybe I need to grab one this holiday.Practically everyone has 1080P screens now, most people have 4K. Why are broadcasts still showing sub 1080P resolutions?

I don't understand it either. DirecTV had none of these issues, it was incredibly rare that any station wasn't 1080i HD, but it seems like with Comcast nearly half the stations are still SD. And the Guide with DirecTV was a million times better, channel 13 was recognized as HD ABC without having to be channel 682 and similar stations were all grouped together such as all the big cable channels with original content, science/history channels, etc. I just went with Comcast because the all-in-one package was cheaper, especially when selecting high speed internet and wanting HBO/Showtime. Plus, any hint of rain just ruined DirecTV signal for me even though they tried to fix it multiple times (it should only go out during a really bad storm when you have a solid signal).1080i isn't sub-1080p. I mean, the experience is worse but not the resolution
really? all of these have been HD for years (10+?) on FIOS which mostly has to deal with the same QAM limitations for TV
The Walking Dead purposefully puts a grain filter to do this, that's not because of the cable compressionYup why Walking Dead back when I used to watch look like dog shit. I tune out of my favorite movies due to this. I'd rather watch through streaming service like hulu or prime. Fuck that ota trash.

Do you have a source for this?Practically everyone has 1080P screens now, most people have 4K.
I thought over the air was like 25mbits a second.
What did it say for 1080p screens?Last NPD reporting I can see is from June of last year and says 10% of television owners in the US have a 4K television.
Watching GoT was awful. Dark scene and compression artifacts everywhere. I had to stream to watchI can't stand Comcast picture quality. I have been through different boxes and different tv's and it is terrible. I love the quality of Netflix, Amazon Prime, and most other streaming services. Only reason i put up with comcast is my wife loves HGTV.

Bandwidth and most casual viewers won't be able to tell much of a difference.
Bandwidth plus sports especially can be quite "flickery" at 1080p
ATSC 1.0 and MPEG-2. Both were products of '90s technology, and aimed at CRTs. Running a 1080p CRT was insanely expensive.
Keeping it at 1080i or 720p also frees up enough bandwidth to allow sub-channels, so broadcasters stick to those standards, and since that's the feed the cable carriers get, they stick with it there too.
I know they shoehorned H.264 into ATSC 1.0, but I don't think I've heard of any broadcasters using it. They're skipping ATSC 2.0, and going straight to ATSC 3.0 in the near future, which uses HEVC (heck of an upgrade from MPEG-2) and will support 4K OTA. Gonna need a new set or set-top-box, though.
They have an HEVC decoder, but they don't have an ATSC 3.0 tuner. I'm unsure if that could be added via firmware, or if it will need specific hardware, but the way industry news sites talk about it it seems like it won't be through new firmware.2) Any TV that supports Netflix UHD has a hardware HEVC decoder. That is used for multiple apps and could also be used for OTA broadcasts.
