 CableLabs Cable Systems Overview
Cable television systems traditionally have delivered entertainment video to consumers' homes—with the emergence of fiber-optic technology and the convergence of video, voice and data, many cable systems provide extended services, such as video-on-demand, voice-over-Internet Protocol, and high-speed Internet access.
In the early days of cable television, trunk, feeder, and drop were the coaxial cables that carried the signal from the headend through a series of distribution points to the terminal equipment in a subscriber's home.
As cable operators continue to invest in upgrading their cable systems with innovative technology, a new generation of integrated services will be delivered to homes and businesses around the world.

 White Papers of the NII: Cable Television Technology Deployment
Cable television reached its current form during the mid-1970s when the technology was developed that allowed cable customers to receive satellite transmissions via the cable architecture that had evolved from its beginnings as Community Antenna Television.
Cable then surpassed its original mandate to bring television reception to rural or obstructed areas and became a means for delivering new types of programming through specialty channels for sports, news, movies, home shopping, weather, and so on, and through pay-per-view channels.
Cable also has the potential to deliver a standardized means of electronic health insurance claim filing, and personalized health information systems are being tested that use terminals in the home to connect consumers to a health care databank that advises customers about self care based on their personal medical records.
