Frequently Asked Questions What is Digital Television? Digital television (DTV) is a huge leap forward in television technology compared to analog television that has been widely available since the 1940s. DTV is delivered and displayed using digital encoding, similar to the way a PC operates. By using digital technology, there is no variation in picture and sound quality from the origination point until it is displayed on your television.
Picture Formats What is the Difference Between a Standard-Screen and a Wide-Screen HDTV The type of screen your HDTV has (wide screen or standard screen) determines how the set-top displays programs on the screen. The picture format for an HDTV is a combination of aspect ratio and screen resolution and is different for standard-screen and wide-screen HDTVs. What is Aspect Ratio? An aspect ratio is the ratio of the width to the height of the TV screen.
