HD stands for "high definition" and, as the name implies, refers to the image quality of television or video. MAC Eyeshadow HD TV is a type of television signal, broadcast in the 16:9 aspect ratio (as compared to NTSC's 4:3 aspect ratio). HDTV resolutions are increased from 640 x 480 to either 1922 x 1080 (or 1080i) or 1280 x 720 (or 720p). Because the HDTV signal is digital (rather than analog), the signal can carry huge amounts of information, including full digital audio with multiple channels. Many television viewers prefer HD because of its vivid, lifelike imagery. Additionally, HD viewing offers the ultimate showcase of the finest details.
