What is HD?

HD stands for High-Definition. Television is broadcast in two ways, Standard-Definition (SD) and High-Definition (HD). HD television (also referred to as HDTV) differs from the traditional SD television in picture quality, since HDTV has sharper images, more detail, and better color because it has more pixels per square inch. HD programs also have a different shape. SD programs are optimized for a more square picture with an aspect ratio of 4:3 (width by height). HD programs are optimized for more of a movie feel with a wider screen with an aspect ratio of 16:9 (width by height). The networks and your television set work together to make the picture fit on your TV. Most modern TVs are made to fit the 16:9 ratio which means HD programs fit perfectly to the edge of the TV set, but SD programs are the wrong shape. In order for the program to fit, the networks and your TV add black bars to the sides and/or top and bottom of the picture to make it the right shape. VTel offers both SD and HD programming. There is an extra monthly fee for HD programming from VTel. Contact VTel at (802) 885-9000 or toll free at (800) 279-4049 for the current rate.
