What is the difference between DTV and HDTV? Do I have to have HDTV?
DTV, or digital television, is not the same at HDTV, or high-definition television. Both are digital signals, but HDTV offers a superior picture quality. Both DTV and HDTV are much higher quality than the traditional analog signal. You do not have to get an HDTV tuner to get DTV, however if you are purchasing a new television you may find the increased cost for an HDTV worth the price.
