Giant strides have been made in telecasting technology, and a great leap forward was made when television stations began to broadcast 
programmes from different countries with the help of satellites.Nowadays, direct transmission is done from a satellite, and this is called DBS or Direct Broadcast Satellite technology. In this system your TV set receives the signals directly from the satellite through a special dish aerial that has to be installed. Of course, many homes prefer to have cable TV where the signals reach the TV set through a cable.
