Television transmission is the process of sending audio and visual signals from a broadcasting station to viewers' televisions. This is typically done through various methods, including terrestrial, satellite, and cable systems. Each method uses different technologies to ensure that the signals reach homes clearly and reliably. In terrestrial transmission, signals are sent over the air using radio waves, while satellite transmission involves sending signals to satellites in orbit, which then relay them back to Earth. Cable transmission uses physical cables to deliver content directly to homes. All these methods aim to provide viewers with access to a variety of television programs and channels.
