If you're talking about "HD" and the highest quality for that standard, there's the term "1080p." My understanding is that a screen is divided up into 1080 "lines" of picture, and 1,920 "columns." Each intersection of a line and a column is the smallest "pixel" you can address. Just to store all those coordinates, you'd need up to 1,080 x 1,920 = 2,073,600 pieces of information.
Each pixel can show a color. Actually, I think "pixels" on a real TV are a red, green, and blue square that work together. Believe it or not, with just over 250 shades of red, green, or blue, you can combine them in ways that represent more than 16 MILLION distinct colors! "Black" is when there's no amount of any color. "White" is when they're all shining at maximum brightness. "Gray" is when all three are at the same brightness (but not maximum or zero). The other colors have different amounts of red, green and/or blue. To make the number 250 in computer language, you need up to eight digits. There are three primary colors, so that's 24 digits per pixel. Now let's multiply our 2,073,600 pixels by 24 digits to get ... 49,766,400 pieces of information.
All that work, and we've only displayed ONE still picture. The idea of a "still" picture is weird all by itself, because didn't any time "pass" while the camera shutter opened and closed? But, to move on, you need about 30 of those "still" pictures PER SECOND to make your eyes believe that things are moving around. That means you have to multiply again: 49,766,400 x 30 = 1,492,992,000 pieces of information!!!
That number is more than a billion, and all you've done is to show ONE SECOND of video. There are copper wires that theoretically send a gigabit of data per second ("giga" for computers is actually a little more than a billion, because they multiply by 2 instead of 10), but that's still not enough, and you'd prevent anything else from using the network connection.
Of course, the 1080p example I gave seems to be rare. I'm pretty sure "HD" on a streaming service might only mean 720p, and then your TV has to make up some pretend pixels to fill a 1080p screen. Also, the only full 1080p content are movies, and those use less frames per second (24) than video. The math goes down to "only" 1,194,393,600 pieces of information to track. That's just for the video. Normally, we like to have sound playing, right?
Anyway, I know that video is hardly EVER sent in an uncompressed format like the way I did all that math. Starting from the "still" pictures, there are some tricks you can do if you put your mind to it. Like, if several hundred pixels are all the same color, or extremely close, imagine picking a symbol (it could just be a small number), and replacing the 24 bits of color with number 1 and so on. When the file gets decompressed later (inside the TV's circuits), all of the 1's get replaced with the repetitive color code (which is much longer, at 24 bits). I'm sure the software looks for more complex patterns than that example, but I haven't really read about those (it might just get confusing).
Within several consecutive frames of video, I'm sure there are other "magic tricks." Like, let's say for at least half a second the camera never moves, and the background stays the same. You could replace all of those pixels across MULTIPLE frames with abbreviations or symbols, and not need to repeat the same information.
Somehow, whatever they do to the digital files, it all works and kind of looks like moving pictures to your eyes. I'm thinking that we may always need compression (since they only want to keep going up in the number of pixels and the shades of colors), and it might not be a bad thing. My example from a few paragraphs above this one is actually "lossless" compression if you did it in exactly that way (only pixels with the SAME value get shortened to a symbol that uses less bits). My understanding is how most compression techniques are "lossy" (bits get permanently changed from the original), but your eyes can't see a difference. In other words, they try to make the picture "visually lossless," and shrink the file to a manageable size.
So, yeah. That's a nerdy explanation for how you can have an Internet speed of "only" two or three megabits per second and still stream certain videos. I mean, two or three MEGAbits sounds amazing when I can remember the days of "dial up" and AOL. Now it's considered kind of "slow," and most people have local networks that are 100+ megabits/second for just the wireless portion.
Meanwhile, when am I going to focus on my homework and not these other techy things? My major is Information Technology.
