What is DTV and HDTV?
DVD’s and satellite systems have a digital encoding for their content- giving a much clearer picture than the old analog TV signal. To play it on your analog TV, the digital signal has to be converted to an analog format. Showing it on a digital display means no conversion need so take place, and the picture is greatly improved, with about 10 times more picture detail. So a DTV digital television means pure digital signals played on a digital display. HDTV is the hightest DTV resolution standard. (There are 18 DTV standards, and 6 of them are HDTV in varying formats.
