Terrestrial television or broadcast television is a type of television broadcasting in which the television signal is transmitted by radio waves from the terrestrial (Earth based) transmitter of a television station to a TV receiver having an antenna.  The term is more common in Europe, while in North America it is referred to as broadcast television or sometimes over-the-air television (OTA).  The term "terrestrial" is used to distinguish this type from the newer technologies of satellite television (direct broadcast satellite or DBS television), in which the television signal is transmitted to the receiver from an overhead satellite, and cable television, in which the signal is carried to the receiver through a cable.
