Community antenna television, commonly known as CATV, is a term that refers to a system of providing television signals to a large area through a single antenna. The spelling of catv is phonetically transcribed as /kəˈmjuːnəti ænˈtɛnə tɛlɪˈvɪʒən/. The word "community" is pronounced with three syllables, with the stress falling on the second syllable. "Antenna" is pronounced with four syllables, with the stress falling on the second syllable. "Television" is pronounced with four syllables, with the stress falling on the third syllable.
Community antenna television (CATV) is a system that enables the distribution of television signals to multiple users within a specific community or region. It involves the use of a shared antenna system to receive and distribute television broadcasts, typically delivered via coaxial cables. CATV is often referred to as cable television and is designed to overcome the limitations of broadcast television signals, which could only be received by individuals with their own antennas.
In a CATV system, a central antenna receives various television channels and transmits the signals through a network of cables to multiple subscribers. The signals are distributed from the central location to households and businesses in the community, allowing users to access a wide range of TV channels and programming options. This centralized distribution approach allows for better signal quality and reception compared to traditional broadcast systems.
CATV networks are usually operated by cable television companies, which provide subscribers with access to a diverse range of channels, including local, national, and international broadcasts. In addition to television channels, CATV systems can also transmit other services such as internet access and telephone services. This integration of services has led to the evolution of cable companies into multiple system operators (MSOs), offering bundled services to subscribers.
CATV has revolutionized television consumption by improving the quality and variety of available channels. It has also facilitated the emergence of pay-TV models and interactive services, transforming television viewing from a limited and passive experience to a more personalized and interactive one.
