can someone explain tvs to me?

Question

what is the difference between 720p and 1080p and 1080i i dont understand all this stuff with tvs!

Answer 1

INTERLACE VS PROGRESSIVE

Look at a standard def television. Notice the horizontal lines in the image? This is interlace: The beam 'paints' the odd lines, then goes back and paints the even lines. The time delay causes those horizontal lines.

Look at your computer monitor. Notice the horizontal lines? No. Your computer monitor is a progressive device. All the rows of video are painted in 1 progressive pass.

720 VS 1080

In the 1940's they created the video standard. 480 lines of video designed to fit a nine-inch tube.

When they came up with HighDef - they realized that TV's were bigger and needed more detail. 720 lines of video gives a lot more picture quality and some people wanted 1080. So they allowed both.

720 is what most TV stations broadcast. 1080 was a lot more information to broadcast and electronics had trouble keeping up a few years ago, but this has changed and now the new HD-DVD players and BluRay players can output 1080 lines of video for stunning picture quality.

Answer 2

Okay. TVs are boxes with little people living inside. When you turn on the TV you can watch everything the little people do. When you change channels, you get to watch different little people. You can even watch little Spanish people! Or you can mute the little people and play music to make it look like they're singing. Have fun!

Answer 3

720 and 1080 are the lines of resolution the higher the better the p is for projection the i is for interlaced wich is better as well

Answer 4

That is the ''resolution'' or how ''clear'' your picture can be. The more pixels (higher number) the ''sharper'' your image will appear.
