| - Digital television supports many different picture formats defined by the combination of size, aspect ratio (width to height ratio) and interlacing. With terrestrial broadcasting in the USA, the range of formats can be coarsely divided into two categories: HDTV and SDTV. These are typically the formats you will be exposed to:
* 480i - The picture is 704x480 pixels, sent at 60 interlaced frames per second (30 complete frames per second).
* 480p - The picture is 704x480 pixels, sent at 60 complete frames per second.
* 720p - The picture is 1280x720 pixels, sent at 60 complete frames per second.
* 1080i - The picture is 1920x1080 pixels, sent at 60 interlaced frames per second (30 complete frames per second).
* 1080p - The picture is 1920x1080 pixels, sent at 60 complete frames per second. (The "p" and "i" designations stand for "progressive" and "interlaced." In a progressive format, the full picture updates every 60th of a second. In an interlaced format, half of the picture updates every 60th of a second.) The 480p and 480i formats are called the SD (standard definition) formats, and 480i is roughly equivalent to a normal analog TV picture. When analog TV shows are upconverted and broadcast on digital TV stations, they're broadcast in 480p or 480i. The 720p, 1080i and 1080p formats are HD (high definition) formats. When you hear about "HDTV," this is what is being discussed -- a digital signal in the 720p, 1080i or 1080p format. Finally, the HD formats of digital TV have a different aspect ratio than analog TVs. An analog TV has a 4:3 aspect ratio, meaning that the screen is 4 units wide and 3 units high. For example, a "25-inch diagonal" analog TV is 15 inches high and 20 inches wide.
