High definition television (HDTV) is the highest form of digital television. It has an aspect ratio of 16:9, which is apparently similar to that of a cinema screen. HDTV has two advantages over the old format of analog TV – the big screen and the resolution.

The wide screen is good in our view – is the large rectangle image better than the old square format. Basically, our eyes see better from left/right than up/down. The wide screen we have more from the scene on the screen that are ideal for sports and movies.

HDTV resolution is probably the biggest selling point. HDTV resolutions 720p, 1080i and 1080p – the number, the number of rows that the image and the letter describes the type of scanning used by the TV for the image. because the more lines for better image. This is a similar concept to digital photos and to determine the print quality of page.
