Community Antenna Television (CATV)
Community Antenna Television (CATV), also known as cable television, involves the reception of distant television signals using a satellite dish or high master antenna. After the signals are captured, they are relayed to residents of a specific area, such as a city or town. This setup enables subscribers to access a range of television content, including national network television broadcasts and specialized stations. Additionally, subscribers may opt for premium channels, such as HBO, for an extra fee.
Examples
Local Cable Provider: A town’s local cable provider captures signals from a satellite dish and transmits multiple channels, including local news, sports, and international broadcasts, to its subscribers.
Premium Channel Bundles: A subscriber chooses to add a premium channel bundle that includes HBO, Showtime, and Starz for additional entertainment options.
Specialized Networks: An educational institution subscribes to a cable package that includes specialized educational channels and resources to assist with their teaching programs.
