The idea is simple, the aspect ratio is the fractional relation of the width of a video image compared to its height. Say what? Aspect ratio is the ratio of the picture width to the picture height. What you've been watching is the square-ish 4:3 aspect ratio, and the newer aspect ratio is the rectangular (16:9 aspect ratio) screen or widescreen format.
The newer rectangular 16:9 format is designed to adapt better to our regular way of seeing and to emulate the theatre experience. We view nearly everything in a type of "widescreen" format. What we normally see on a daily basis is in this format. As we drive a car, we look through a windshield that more resembles the wide rectangle than the square view. Our peripheral vision refers to the things that we see to the sides of our viewing, the horizontal plane, not the things we see in the vertical plane. In our normal everyday living we see things through a narrow field of vision. We see the things on a horizontal plane, we see a horizon and we view things along a horizon. The 16:9 aspect ratio attempts to mimic our normal field of vision as we process things from side to side. We mostly see the things directly in front of us and side to side. We don't walk around viewing floors and ceilings without consciously taking a glance up or down before returning to our normal frame of reference, dead ahead. If you're purchasing a new HDTV, we suggest the 16:9 format as the best choice for now and future viewing. Either format may cause you some frustration as programming now comes in both formats to your TV. You will be adjusting your TV's aspect ratio on the screen to suit what is the most comfortable viewing to you. As the digital transition progresses and more content is sent in HD, the widescreen format makes the most sense as this new and expanded content is designed to be viewed in 16:9 format. More...
