January 3, at am. We're starting to see the roll-out of ATSC 3. Just like the initial roll-out of HDTV at the turn of the century, it's going to be a while before 4K programming is common over the air.
Before "4K" became common, you'd almost never see "2K. It's 2, pixels wide, and again, no vertical resolution is specified by the DCI. But now that "4K" has gained traction as a term used to describe TVs and content, "2K" is becoming increasingly common as shorthand for the p resolution used by most smaller and older HDTVs, as well as Blu-ray.
Remember how we talked about digital cinema resolutions only specifying the horizontal resolution? Well TVs, on the other hand, have historically used the vertical to describe resolution going back to the glass tube days.
So p is the vertical resolution. Nearly all HDTVs have an aspect ratio of 1. This is another source of confusion, since decades of TV discussions have talked about vertical resolutions, and then all of a sudden we're talking about "4K TVs," which refers to the horizontal resolution. Don't blame me, it wasn't my idea. Which is why p is not "1K. That said, most people don't call p 2K; they call it p or Full HD. By the way, i is the same resolution as p , but no modern TV is i.
Roughly half the number of pixels of p. It's rare to find a TV that's p anymore. This goes back to the initial HD transition at the turn of the century. And if you're wondering why your TV doesn't say "p" on those channels, check this out. In the computer world they use an incomprehensible and shockingly un-user-friendly jumble of letters to describe resolution. Well, not "shockingly" since these are computers.
Look, I'm a computer guy, building my own PCs since the early '90s, and even I can't tell you what half these letters mean. I can understand that initially they were implemented to make things easier, but we've got so many resolutions and combinations that now they're just annoying.
The rest, you can dive into and print yourself a cheat sheet from this. Fortunately, the only time most of you will come across this letter goulash is if you're looking for a cheap data projector or a computer monitor. Scharon Harding. Topics Monitors.

HDTVs, especially those that are inches or larger , have at least a p display or pixel resolution. This means that if you input a signal into a p TV that has a resolution of less than p, the TV processes that signal so that it displays the image on its entire screen surface. This process is referred to as upscaling. This also means that input signals with less than p resolution don't look as good as a true p video resolution signal because the TV has to fill in what it thinks is missing.
With moving images, this can result in unwanted artifacts such as jagged edges, color bleeding, macroblocking, and pixelation this is the case when playing those old VHS tapes. The more precise guess the TV makes, the better the image will look. The TV shouldn't have difficulty with p input signals, such as those from Blu-ray Disc and from streaming, cable, or satellite services that may offer channels in p. TV broadcast signals are another matter. Although p is considered Full HD, it is not officially part of the structure that TV stations use when broadcasting high-definition video signals over the air.
Also, 4K TV broadcasting is on the way. Actively scan device characteristics for identification. Use precise geolocation data. Select personalised content. Create a personalised content profile. Measure ad performance. Select basic ads.
