How to explain high definition to your parents

[howdini, get yourself a guru] Hi there. I'm Veronica Belmont. [Veronica Belmont, technology guru] Let's talk about how to explain HD to someone who's maybe not the most tech savvy, like your parents perhaps. It's really not as complicated as all the numbers sound. Standard definition TVs are analog and have an aspect ratio of 4x3 with 480 lines of resolution with interlaced delivery. [Standard TV, Analog, 4:3, 480 lines, Interlaced] Now I'll tell you what that means and how it translates to the HDTVs we all enjoy watching now. [HDTV, Digital 16:9, 720 or 1080p, Progressive] Aspect ratio is just a fancy name to describe the size of the screen. Standard definition sets, the ones your parents watched, were closer to being square, 4 units across by 3 units high. HDTVs have a wider screen, more like a movie theater screen, and are built with a 16 by 9 aspect ratio. The conventional set delivered 480 lines of resolution and today you can get high definition sets with 720 or full high definition sets that have 1080 lines of resolution. Seven hundred and twenty lines of resolution is great for smaller sized HDTVs, like 32 inches and below. [Full HD 1080p, Highest at home resolution available] For larger sets, you're going to get the best picture with 1080p. [Interlaced vs. Progressive] Now what about this I versus P that you've heard of? Simply, it refers to the way the TV scans those lines of resolution. I stands for interlaced, which means the TV displays the image on the screen by alternating lines on the screen. P, or progressive, displays all the lines of the picture all at once, making it indeed the superior picture quality. Now for the last item to compare, analog versus digital signal. [Analog vs. Digital] Now that the TV has the great technology I just explained, you need the signal to comply. Old TV signals used to be analog, which means sent through a radio frequency. A digital signal is a binary code sent by computer. That's a pretty simplified way to explain a complicated process, but what you want to know is that signals are now sent digitally, which makes clear high definition possible. Now for the proof. [Full HD 1080p picture quality] I mean, look at this gorgeous picture. And HD applies to sound, too. [Complete your HD experience with surround sound audio] Surround sound audio accompanies that beautiful picture for a true full HD experience. Now when you listen to HD you'll hear exactly what the sound engineers intended, which is pretty amazing. Blu-ray disc technology is another advancement that assists with HD. It provides the highest resolution possible. Right now it's the only way to get the maximum picture quality out of your TV. This disc right here holds five times more information than a regular DVD and is true 1080p source and can support up to 7.1 channels of high definition audio. There's no denying this is a better experience than what your parents are used to. Once you and your parents see and hear the difference HD makes, there's really no comparison the the old standard definition TV. Just tell them you don't want to miss a thing, and if they haven't upgraded yet, now is the time. I'm Veronica Belmont with Sony for Howdini. For more great tips and ideas, go to
