High-Definition TV is not as complicated as you might think, but there are two basic obstacles to your High-Definition viewing pleasure. Firstly, you can only receive HD images from a HD-capable source box, such as SkyHD, NTL, Telewest or Freeview. Secondly, you can only view true HD images on special HD Ready screens. This effectively means that the home entertainment systems the vast majority of us currently have simply won't cut the mustard come the High-Definition revolution.
High-Definition TV (HDTV) is the most exciting thing to happen to television since black and white turned to colour. The main fact you need to know is that HDTV pictures contain four times as much picture definition as the standard TV pictures we watch currently. This translates into a picture that is bursting with extra clarity, sharpness, depth and a realism that is impossible to believe without seeing it for yourself. Sound quality is also typically far better with HDTV as most High-Definition programmes contain 5.1 Dolby Digital surround sound.
