How is Digital TV different than regular TV?
Digital television is the same regular TV programming and the same broadcast stations that have been available for free. With new technology, that programming is now delivered over-the-air using a digital signal. The digital signal assures that the picture and sound will be crystal clear. In addition, High Definition TV can be carried on DTV transmissions. HDTV offers a much higher resolution picture and sound than standard or conventional television broadcasts, but requires an HDTV-capable display to see its full potential.
