Cable television or Community Antenna Television (CATV) (often shortened to cable) is a system of providing television, FM radio programming and other services to consumers via radio frequency signals transmitted directly to people’s televisions through fixed optical fibers 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.

It is most commonplace in North America, Europe, Australia and East Asia, though it is present in many other countries, mainly in South America and the Middle East. Cable TV has had little success in Africa, as it is not cost-effective to lay cables in sparsely populated areas, and although so-called "wireless cable" or microwave-based systems are used, "direct-to-home" satellite television is far more popular, especially in South Africa.

Technically, both cable TV and CATV involve distributing a number of television channels collected at a central location (called a headend) to subscribers within a community by means of a network of optical fibers and/or coaxial cables and broadband amplifiers. A television network is a distribution network for television content whereby a central operation provides programming for many television stations. ...

For the British rock band of the same name, see Amplifier (band) An amplifier can be considered to be any device that uses a small amount of energy to control a source of a larger amount of energy, although the term today usually refers to an electronic amplifier. ...

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. A tuner is a device to adjust the resonant frequency of an antenna or transmission line to work most efficiently at one frequency or band of frequencies. ... The video cassette recorder (or VCR, less popularly video tape recorder) is a type of video tape recorder that uses removable cassettes containing magnetic tape to record audio and video from a television broadcast so it can be played back later. ...

The same program is often simultaneously broadcast by radio and distributed by cable, usually at different frequencies. Other programs may be distributed by cable only; rules restricting content (e.g. regarding nudity and pornography) are often more relaxed for cable than for over-the-air TV. Nudity or nakedness is the state of wearing no clothing. ... Pornography (from Greek Ï€ÏŒÏÎ½Î· prostitute and Î³ÏÎ±Ï†Î¯Î± writing) (more informally referred to as porn or porno) is the representation of the human body or sexual activity with the goal of sexual arousal. ...

Traditional cable TV systems worked strictly by way of analog signals (i.e. using standard radio waves) but many modern cable TV systems also employ the use of digital cable technology, which uses compressed digital signals, allowing them to provide many more channels than they could with analog alone. An analog or analogue signal is any variable signal continuous in both time and amplitude. ... Digital cable is a term for a type of cable digital television that delivers more channels than possible with analog cable by using digital video compression. ...

Many cable television systems were formerly known as CATV (Community Antenna Television) systems as they were originally composed simply of a shared antenna located in a high location to which multiple households could have their TVs connected via coaxial cable. This was designed to provide access to television signals in areas where reception was traditionally poor. As cable-only networks began to appear on CATV systems, picked up via satellite rather than by antenna, the use of the term CATV has largely faded and the term cable television has taken its place.

Cable television is normally regarded as a natural monopoly, and most areas are served by a single provider, though Australia is characterised by extensive duplication. In economics, a natural monopoly occurs when, due to the economies of scale of a particular industry, the maximum efficiency of production and distribution is realized through a single supplier [citation needed]. Some free market-oriented economists argue that natural monopoly exists only in theory, and not in practice. ... In computer science, duplication of data or objects involves copying data byte by byte and, if needed, changing metadata about objects. ...

Cable television deployments

Australia

Cable television services have been available in Australia since 1995. There are currently three major and four minor digital cable television providers in Australia - Foxtel, which is a 50/50 joint agreement by Telstra and News Corp, Optus TV and Austar. A newcomer, SelecTV, provides a cheaper service with a more limited array of channels and features.

Services, channels and usability have drastically improved since the days of analogue. While many people outside the capital cities are still unable to reach the cable network, satellite services provided by the top providers have now been able to provide the same standard of quality and usability (Video on Demand, Live TV Manipulation, Dolby Digital) that cable subscribers are able to access.

Most providers are able to offer in excess of 60 channels, including 24-hour news services, movie channels, on-demand events and films, as well as terrestrial digital (DVB) free-to-air channels. Features such as timeshifting, on-demand recording, games and interactive TV are also available. Channels include but aren't limited to Discovery Channel, History Channel, Showtime Australia, Sky News Australia, Movie Network (A group of 3 separate movie channels), CNN, BBC World, MTV, ESPN and more.

Due to its history, financial backing and market dominance, most locally produced content and channels are either owned directly by Foxtel or through subsidiary companies. Channels that Foxtel own are then wholesaled to other providers, while individual channels not owned by Foxel will sell their licensing rights in content sharing agreements. This way, all providers are able to share from the same pool of channels, while still being able to set their own pricing, packages and brand.

In terms of coverage, Foxtel's cable network covers most of Sydney, Melbourne, Brisbane, Adelaide, and Perth. Optus's network covers small parts of Sydney, Melbourne, and Brisbane, though its restrictive subscription rules means that many people living in apartments or confined living areas are unable to be connected. Austar is available by satellite in regional and rural Australia, but does have a small cable network in the city of Darwin. Austar and Foxtel only compete for customers in the Gold Coast but by a mutual non-compete agreement, Foxtel limits its market to the capital cities and Austar limits its market to regional and rural areas.

The first cable system started to operate in the early Sixties in Monterrey, as a CATV service (an antenna at the top of the Loma Larga, which could get TV signals from South Texas). Most of the other major cities didn't develop cable systems until the late Eighties, due to government censorship. By 1989 the industry had had a major impulse with the founding of Multivisión—a MMDS system who started to develop its own channels in Spanish—and the later development of companies such as Cablemas and Megacable.

United Kingdom

In the UK Cable Television had its origins in 1938, when the first Community Antenna TV systems were setup in towns including Bristol and Hull, for homes which couldn't receive transmissions over the air; however these signals were on the 405-line system. In the 1960s Rediffusion Vision was setup to provide cable television in the newer 625-line and PAL formats. It has been suggested that this article or section be merged with Greater Bristol. ...

In the United Kingdom, the current generation of cable television began in the late 1980s with the issue of franchises to many local operators. These small operations proved uneconomic and there has been a continuing process of consolidation and re-financing. The 1980s decade refers to the years from 1980 to 1989, inclusive, informally sometimes including the years 1979, 1990 and 1991. ...

By 2000 the two principal cable operators were NTL and Telewest. NTL's cable service was originally known as CableTel and grew rapidly through the acquisition of, among others, ComTel (which itself had bought Telecential), Comcast, Diamond Cable and finally, in 1999, the residential and small business operations of Cable & Wireless. Telewest also steadily acquired local operators. NTL Incorporated, a U.S.-listed British company, provides cable services (internet, telephone and television) While NTL has its headquarters in New York City, the companys activities focus heavily on the United Kingdom, with operational headquarters in Hook, Hampshire. ...

Cable TV faces intense competition from SkyDigital's satellite television service, although most channels on that platform are also carried on cable (however they do lack features- for example interaction news or football - available to Sky Digital viewers). Very few channels are now exclusive to cable, usually channels showing local programming. However, subscription-funded digital terrestrial television proved less of a competitive threat, as ITV Digital went into liquidation in 2002. The re-launch of DTTV as the free Freeview service has been a success in introducing people to multichannel digital TV and seems not to have adversely affected the growth of cable and satellite subscribers. British Sky Broadcasting (BSkyB â€” formerly two companies, Sky and B.S.B.) is a company that operates Sky Digital, the most popular subscription television service in the UK and Ireland. ...

Another potential source of competition in the future will be TV over broadband. This was initially launched, using ADSL, in London, where it is provided by HomeChoice. An IPTV service was also provided in Hull by Kingston Communications, but this ceased operations in April 2006.

Switzerland

In Switzerland, there is practically no household that doesn't have cable TV. Ironically, despite this good coverage, Switzerland has only a few state TV stations (two each for the German, French and Italian-speaking parts of the country); there are no private stations with an outreach comparable to these state channels. To watch news or political information; Swiss channels are preferred, but in the entertainment sector (feature movies, comedies, talk shows), private TV stations from Germany, France and Italy are dominant.

Other cable-based services

Coaxial cables are capable of bi-directional carriage of signals as well as the transmission of large amounts of data.

Broadband internet is achieved over coaxial cable by using cable modems to convert the network data into a type of digital signal that can be transferred over coaxial cable. One problem with some cable systems is the older amplifiers placed along the cable routes are unidirectional thus in order to allow for uploading of data the customer would need to use an analog modem to provide for the upstream connection. This limited the upstream speed to 56k and prevented the always-on convenience broadband internet typically provides. Many large cable systems have upgraded or are upgrading their equipment to allow for bi-directional signals, thus allowing for greater upload speed and always-on convenience, though these upgrades are expensive. Cable modem for broadband Internet access A cable modem is a unique type of modem that is designed to modulate a data signal over cable television infrastructure. ... A television network is a distribution network for television content whereby a central operation provides programming for many television stations. ...

Another service being added to many cable systems is cable telephone service. This service involves installing a special telephone interface at the customer's premises that converts the analog signals from the customer's in-home wiring into a digital signal, which is then sent on the local loop (replacing the analog last mile, or POTS) to the company's switching center, where it is connected to the PSTN. The biggest obstacle to cable telephone service is the need for nearly 100% reliable service for emergency calls. One of the standards available for digital cable telephony, PacketCable, seems to be the most promising and able to work with the Quality of Service demands of traditional analog POTS service. The biggest advantage to digital cable telephone service is similar to the advantage of digital cable TV, namely that data can be compressed, resulting in much less bandwidth used than a dedicated analog circuit-switched service. Other advantages include better voice quality and integration to a VoIP network providing cheap or unlimited nationwide and international calling. Note that in most cases, digital cable telephone service is separate from cable modem service being offered by many cable companies and does not rely on IP traffic or the Internet.
