What is Direct HDTV: 720p vs. 1080i format
Everyone loves a clear television picture in hi-def. The increased pixel count makes it so and eventually
all TV broadcast will be in hi-def.
HD is the answer if you're looking for the clearest viewing picture money has to offer. Actually it doesn't cost that much extra and you get twice the number of pixels that you would have seen with conventional analog TV. There are more than 130 HD channels you can view with the leading satellite broadcaster.
Pixel ratios for standard definition television receiver is 480 scanning lines (704 x 480) stacked top to bottom. The resolution of a fixed-pixel display is defined by the total number of horizontal pixels across each scanning line. Here we have 704 pixels for each scanning line.
For High definition television you need more pixels. Most common HD nomenclature has what it calls a 1080i progressive format. Naturally, a plasma, LCD or DLP devices need to have the capability to display those extra pixels.
There are 2 types of scan. Interlaced and progressive scan. High-definition video mode, known as 720p, the p would stand for progressive scan. 1080i is the shorthand name of a format for interlaced scan.
1080i ((1920 x 1080)) has more lines and pixels than 720p (1,280 x 720 pixels), but 720p is a progressive-scan format that should deliver a smoother more viewable image that stays sharper during motion.
With 1080i, you do see all 1080 lines at once due to residual light imprinting on your eye. It is much sharper when the image is still. With 720p the motion is smoother and better for viewing faster action situations like animals on the run or sports.
HD DVR recorders allow you to record HD broadcasts and replay them later. Direct TV offers a free HD DVR that lets you record 50 hours of HD or up to 200 hours of standard digital broadcast television. You can even watch one show while recording another.
