not sure if this 4K stuff is gonna take off

[itsyoung!!]

I'm pretty sure 1080i draws half the pixels in one pass then the other pass draws the other half alternating while 1080p draws the full picture in every pass. Is that not why 1080p uses twice the bandwidth of 1080i?

1080i
Most HDTV channels are broadcast in 1080i resolution. Programs broadcast in 1080i are sent at a ratio of 30 frames per second. Each frame has 1,808 vertical pixels interlaced with 1,920 horizontal pixels to create a continuous picture on your TV screen. Because 1080i is broadcast in an interlaced image, images such as a speeding car can blur when they move fast. The lines of the image are not rendered contiguously, which can cause a "messy" or blurred picture. It can also cause image skipping, where it looks like the image is delivered in stop-motion photography.

1080p
1080p HDTV resolution has the same number of pixels -- 1080i per frame -- but the image is sent at 60 frames per second instead of 30. The higher rate of frames per second in the progressive scanning of 1080p means that it takes up to twice the bandwidth as 1080i. Subsequently, many TV cable companies transmit or broadcast data in 1080i to prevent lag in the cable feed. This results in a lower resolution picture, but without the inconvenience of having your TV picture freeze or skip ahead without showing all of the program you are watching.

interlaced pictures draw half the picture in one pass than the other half in a second pass alternating between odd and even rows. Only saying it's 30 fps is deceptive because its not sending the whole picture at the same time.

no, its like battlefield 4 for xbox 1 is 30 FPS but for PC is 60 fps(if played at same resolution and graphic settings).. its just smoother frame rate. If you ever used Sony Vegas itd be like if you rendered something at 30 FPS it would be insanely quicker to render than if you did it at 60 FPS but the amount of pixels is the same..

a pixel is a pixel, it being a slower frame rate doesnt effect the actual picture itself, but in a moving picture itll make it more smooth looking (its why you think its more pixels, etc).

interlaced means it is sending only half the image at a time, just like winb83 said. that gap between the odd and even numbered scanlines is what causes blurriness when objects move fast on an interlaced video signal. progressive scan, regardless of frame rate, eliminates that kind of visual artifact.

To be honest 1080p is more than good enough for the general public for now. TV is isn't 1080p, plus people watch stuff on their phones and tablet and stream stuff on the Internet. The requirement for that being 4k is next to zero.

4K and above probably won't become standard until 3D or the next innovation of watching TV becomes the next big thing and it's needed to keep the immersion.

From PCmag.com;

1080i video is "interlaced." 1080i video plays back at 60 frames per second, but that's a bit deceptive, because it's actually broadcast at 30 frames per second. The TV then displays those frames twice, in a way—the first pass is 1,920-by-540 for the even scan line field, and the second pass is 1,920-by-540 for the odd scan line field. The process by which this occurs is called interlacing. It contributes to a sense of motion and reduces perceived flicker.

1080p video is called "progressive scan." In this format, 1,920-by-1,080-pixel high-definition movies are progressively drawn line after line, so they're not interlaced. On paper, that may not seem like a huge deal. But in the real world, what you end up seeing looks sharper and more defined than 1080i, particularly during scenes with a lot of fast motion.

isnt that what I just said

4K is a resolution not a gimmick or half baked technology. Sure there might be higher resolution but 1080p TVs have been in what seems forever and 1080p is still it fully adopted. Because guess what higher resolution is always better.


Lol @satam55 saying studios don't shoot at 4K resolution. Most films are shot at 2K at least which is double the resolution of 1080p and most newer films have been shot with 4K or higher

 

[Kuwka_Atcha_Ratcha]

Hence why I said as the tech becomes cheaper and better...its probably gonna take a while longer than the jump to hd because there are diminishing returns going from 1080 to 4k and the average consumer can't justify the cost when hd already looks good enough...but as bandwidth increases and the price to make and view 4k content drops it will get more widespread...do u expect us to use 1080 forever?

nope not forever, but what I do think is by the time infrastructure is ready, we'll go straight to 8k.

 

[Kuwka_Atcha_Ratcha]

1080i is same as 1080p just at 30 fps instead of 60 fps... dont you console players all scream about how you cant tell the difference between 30 and 60 fps or that its not a big deal

the fact you think 30fps and 60fps in video games means as much as it does in moving film/tv makes me know you know nothing on this topic.

hey point me in the direction where I can either download or purchase my favorite movies in 4k,

You talk about movies but blu ray is 30 fps (really 24 fps but techiques to make it 30 fps)

You just have no idea what you are talking about

tell me where I can purchase 4k blurays
tell me what 4k video games I can play on a console
tell me where I can watch my favorite youtube content in 4k
tell me what tv networks broadcast in 4k

if you can't do any of the above, it shows the technology isn't a) read or b) practical

You must be young. People said the same about dvd to blu ray transition.. Blu ray players were expensive as hell ($300-500+ for a player when dvd players were like $80. )
Blu ray players were as expensive as the average tv is now

But now blu ray is popular.

young? I already told you I buy all the new tech

when dvd first came out , you had PS2 ready!!! which ran DVD games, played DVD's and within the first few months there was a shyt load of DVDs readily available.
bluray was expensive, but we had PS3 to run blurays on, and there was a shyt load of bluray's also,

so you not gonna answer any of the questions I asked?

The resolution of a 1080p 16:9 image is 1920 x 1080. The resolution of a 2K 16:9 image is 2048 x 1152. That's not a noticeable difference. Television resolutions such as 480p, 720p, & 1080p are measured vertically. Cinematic resolutions like 2K, 4K, & 8K are measured horizontally.

And yes most movies ARE NOT being mastered or shot in 4K. You can just go to IMDB & look up the technical specs for each movie. For example "The Man from U.N.C.L.E." that just came out this past weekend was shot digitally in 2.8K.
