DIGITAL TV BY TERRESTRIAL TRANSMITTERS
For decades, terrestrial TV was the only way to watch TV. The only exception was MATV systems which could more or less be regarded as an extension of the terrestrial transmitters.
Terrestrial TV is the oldest way of distributing TV and for this reason, all TV sets are equipped to receive these signals without any access to either cable TV networks or satellite dishes. Terrestrial TV is still very popular today. In an astounding way, terrestrial transmissions have been able to withstand the competition from cable and satellite. Even viewers who have access to satellite TV still use terrestrial TV as a complement for reception of the basic free to air channels.
