The picture and sound to be transmitted is first converted into electrical signals. These electrical signals are then converted into a special type of waves and transmitted in air from a transmitting antenna. The artificial satellites have special instruments which receive the signals transmitted by the earth stations. The signals so received are then amplified and retransmitted, by the artificial satellite that finally reach the televisions at different areas.
