What is High Definition Television (HDTV)?
High definition television (HDTV) is not the same as DTV. HDTV refers to the resolution quality of the picture being broadcast. This is determined by the number of picture elements (pixels) across the screen and the numbers of rows down the screen. HDTV can have up to six times more pixels than the resolution of an analog signal. The higher the resolution, the clearer the picture. Viewers receive high-quality, crystal-clear pictures. These visually stunning pictures are displayed in a wide screen, rectangular format with a 16 by 9 width to height ratio compared to analog’s 4 by 3, or basically square format. The superior picture and sound of HD programs can only be experienced on a high-definition TV set.
