  • Aspect ratio : Standard television has a 4:3 aspect ratio, it is four units wide by three units high. HDTV has a 16:9 aspect ratio, more like a movie screen.
  • Resolution : The lowest standard resolution (SDTV) will be about the same as analog TV and will go up to 704 x 480 pixels. The highest HDTV resolution is 1920 x 1080 pixels. HDTV can display about ten times as many pixels as an analog TV set.
  • Frame rate : A set's frame rate describes how many times it creates a complete picture on the screen every second. DTV frame rates usually end in "i" or "p" to denote whether they are interlaced or progressive. DTV frame rates range from 24p (24 frames per second, progressive) to 60p (60 frames per second, progressive).
