What Is Cable Television?
Cable television is a system of providing television, FM radio programming and other services to consumers via radio frequency signals transmitted directly to peoples televisions through fixed optical fibres or coaxial cables as opposed to the over-the-air method used in traditional television broadcasting (via radio waves) in which a television antenna is required. Technically, cable TV involves distributing a number of television channels collected at a central location to subscribers within a community by means of a network. As in the case of radio broadcasting, the use of different frequencies allows many channels to be distributed through the same cable, without separate wires for each. The tuner of the TV, VCR or radio selects one channel from this mixed signal. What is satellite television? Satellite television is television delivered by way of communications satellites, as compared to conventional terrestrial television and cable television. In many areas of the world satellite
Cable television is a type of delivery system for video programming. It is provided by a cable operator to people that pay for it – called subscribers. The video program is sent to the subscribers television using coaxial cable or fiber optics. Cable companies often use coaxial cable to transmit or send television shows to your television. Coaxial cable is a wire with a stiff copper as the core, surrounded by an insulating material to prevent the wire from transmitting the cable signal through the air. This insulation is covered by a conductor, which often consists of a closely woven braided mesh. The conductor allows the video signal to move through the coaxial cable and into your television set. The conductor is protected by a plastic covering. Fiber Optic lines or optical fibers can also be used as a delivery system for cable video programming. They are made of glass, which is made from sand or silicon and other, inexpensive raw material. The glass used for modern fibers is so trans
