Digital TV doesn't use radio waves. Instead, it converts sound and images into binary code. This is a computer language
which only consists of zeros and ones and broadcasters can
use it to send a lot of information very quickly. This digital
information arrives at a TV via an aerial, a cable, a satellite
dish, or broadband. Then a decoder converts the information
back to sound and images. Decoders are either inside a TV or
computer, or in a separate box which is connected to it. перевод ​
