CATV SYSTEMS
CATV originally stood for Community Access Television but is now more commonly known as Cable TV. CATV is one of the most common methods of transmitted television signals to a consumer's home, using radio frequency signals transmitted through coaxial cable. More recently, CATV can also be transmitted using optical fiber, which utilizes pulses of light to transmit a signal.
CATV offers analog and digital channels (including high definition). Receiving digital channels typically requires a cable box for conversion.
