Digital TV vs HDTV - What Is The Difference?
Just when the difference between HDTV and DTV started to make sense, consumers started hearing about the many different kinds of digital TV. In fact, there are 18 different forms of broadcasting for DTV. The definitions applied to each usually describe the amount of scan lines and scan formats.
For example, 480i means that the digital image is transmitting 240 lines of the picture in tenths of a second and the other 240 lines in the next tenth of a second. The small letter “I” that follows the number means that the picture ‘interlaces’ both sets of lines to create the whole image. One can think of one set of lines as even and the other as odd. 480i is just one of the ways by which digital TV is transmitted to our TV sets.
