Cable Television (CATV), commonly known as cable TV, is a system that delivers television programming to subscribers through a network of coaxial or fiber optic cables. It offers a wide range of channels and programming options beyond what is available through traditional broadcast television.

Components of Cable Television (CATV) System:

  1. Headend: The central facility where television signals from various sources (satellites, local broadcasters, etc.) are received, processed, and distributed.
  2. Distribution Network: Coaxial cables or fiber optic cables used to transmit signals from the headend to individual neighborhoods.
  3. Nodes: Points in the distribution network where signals are amplified, split, or combined to serve multiple households.
  4. Drop Cables: Cables that connect nodes to individual homes, providing access to cable TV services.
  5. Set-Top Boxes (STBs): Devices used by subscribers to decode and display cable TV signals on their televisions.

Features and Services:

  1. Channel Variety: Cable TV offers a wide range of channels, including local, national, and international programming.
  2. Premium Channels: Subscribers can access premium channels like HBO, Showtime, and more for additional fees.
  3. Interactive Features: Some cable TV systems offer interactive features like video on demand (VOD), pay-per-view (PPV), and digital video recording (DVR).
  4. High-Quality Signal: Cable TV generally provides a clearer and more consistent signal compared to traditional over-the-air broadcast.
