Digital Television

Digital Television - (DTV) digital television theoretically offers better quality pictures than analogue because the digital signal is much less susceptible to interference. It uses MPEG-2 coding for video and audio, and once received, the digital signal is converted back to analogue via a set-top box (STB) or hardware within an integrated television set (iTV). DTV is available via satellite and cable through subscription, or free via terrestrial through a Freeview box. DTV offers the broadcaster the possibility of more channels, as well as interactive services.
