What is the difference between catv and tv
Cable television, also known as Community Antenna Television CATV , provides programming to televisions connected to a community antenna by a cable. This is a paid service that consumers receive via subscription to a cable television provider, and it generally includes different levels of service, beginning with basic.
Basic cable packages usually include a combination of local programming and specialty channels that aren't broadcast over the open airwaves like DTV channels. Premium cable packages usually include specialized programming, such as movies and sports. To confuse matters, there is also digital cable.
This is cable television that, like DTV, is broadcast via a digital signal rather than an analogue signal.
Digital cable is also broadcast in high definition HD , providing the clearest picture on HD-enabled television sets. CCTV is mainly used to refer to a smaller closed system within a building or facility in which video signal obtained from one or more cameras is sent to one or more monitors through coaxial cables.
CATV, short for cable television, on the other hand, is basically a television distribution system that uses a network of coaxial or fiber-optic cables to distribute multiple video channels in the VHF or UHF bands. As the signal is broadband, the only cable with a center conductor of solid copper must be used. RG-6 is the most common type of coaxial cable used for home and commercial cable television systems.
