What is terrestrial TV and how does it work?
Terrestrial TV refers to the traditional method of broadcasting television signals over the airwaves, using a network of transmission towers to cover a specific geographic area. This allows viewers to receive TV channels for free, without the need for a subscription or internet connection. The signals are broadcast in a specific frequency range, and TVs are equipped with tuners that can detect and decode these signals, allowing viewers to watch their favorite channels.
The way terrestrial TV works is that broadcasters transmit their signals from a transmission tower, which are then received by TVs in the surrounding area. The signals are modulated onto a carrier wave, which is then transmitted over the airwaves. The TV tuner in the receiver decodes the signal, extracting the audio and video information, and displays it on the screen. Terrestrial TV has been the primary means of TV broadcasting for decades, and while it has largely been replaced by satellite and cable TV in some areas, it remains a popular option for many viewers, especially in rural areas where other options may not be available.
