Cable television is a system of delivering television programming to consumers via radio frequency (RF) signals transmitted through coaxial cables , or in more recent systems, light pulses through fibre-optic cables . This contrasts with broadcast television , in which the television signal is transmitted over-the-air by radio waves and received by a television antenna , or satellite television , in which the television signal is transmitted over-the-air by radio waves from a communications satellite and received by a satellite dish on the roof. FM radio programming, high-speed Internet , telephone services , and similar non-television services may also be provided through these cables. Analog television was standard in the 20th century, but since the 2000s, cable systems have been upgraded to digital cable operation.
62-461: CSC Media Group , formerly known as Chart Show Channels ( CSC ), was a British cable television broadcasting company. It was a subsidiary of Sony Pictures Television . The company dissolved on 27 November 2019. CSC Media Group was named after the now defunct UK music show The Chart Show , which ran on ITV and Channel 4 for twelve years. CSC evolved from the original Chart Show production company Video Visuals , to Chart Show Channels, which
124-405: A dedicated analog circuit-switched service. Other advantages include better voice quality and integration to a Voice over Internet Protocol (VoIP) network providing cheap or unlimited nationwide and international calling. In many cases, digital cable telephone service is separate from cable modem service being offered by many cable companies and does not rely on Internet Protocol (IP) traffic or
186-436: A given location, cable distribution lines must be available on the local utility poles or underground utility lines. Coaxial cable brings the signal to the customer's building through a service drop , an overhead or underground cable. If the subscriber's building does not have a cable service drop, the cable company will install one. The standard cable used in the U.S. is RG-6 , which has a 75 ohm impedance , and connects with
248-543: A high elevation. At the outset, cable systems only served smaller communities without television stations of their own, and which could not easily receive signals from stations in cities because of distance or hilly terrain. In Canada, however, communities with their own signals were fertile cable markets, as viewers wanted to receive American signals. Rarely, as in the college town of Alfred, New York , U.S. cable systems retransmitted Canadian channels. Although early ( VHF ) television receivers could receive 12 channels (2–13),
310-466: A higher rate. At the local headend, the feed signals from the individual television channels are received by dish antennas from communication satellites . Additional local channels, such as local broadcast television stations, educational channels from local colleges, and community access channels devoted to local governments ( PEG channels) are usually included on the cable service. Commercial advertisements for local business are also inserted in
372-405: A local VHF television station broadcast. Local broadcast channels were not usable for signals deemed to be a priority, but technology allowed low-priority signals to be placed on such channels by synchronizing their blanking intervals . TVs were unable to reconcile these blanking intervals and the slight changes due to travel through a medium, causing ghosting . The bandwidth of the amplifiers also
434-463: A microwave-based system, may be used instead. Coaxial cables are capable of bi-directional carriage of signals as well as the transmission of large amounts of data . Cable television signals use only a portion of the bandwidth available over coaxial lines. This leaves plenty of space available for other digital services such as cable internet , cable telephony and wireless services, using both unlicensed and licensed spectra. Broadband internet access
496-456: A mixture of cartoons, extreme sports, as well as music, aimed for boys, similar to another kids channel, Jetix . Currently, it broadcasts from 06:00 to 23:30 daily. Pop Girl +1 , a 1-hour timeshifted version of Pop Girl launched on Wednesday 4 June, replacing their first music channel timeshift, Flaunt +1 , which had only been on air just short of four weeks. AnimeCentral has been replaced with Showcase TV on 27 August 2008, which simulcasts
558-576: A mixture of channels such as Pop Girl , Chart Show TV , True Movies 2 , along with AnimeCentral programming block with repeats of Cowboy Bebop and Ghost in the Shell: Stand Alone Complex . CSC was the majority owner of Moving Movies Ltd, with True Movies 1 being the first channel from the company, it launched on 8 April 2005 and was joined by True Movies 2 in March 2006. Both channels showed mainly made-for-TV movies from
620-618: A range of genres, all based on real-life events and people. They were announced as being one of the channel providers providing DVB-H channels in a 16 channel trial of the technology in Oxford , a system which would have carried Chart Show TV. CSC was one of the parties involved in bidding for a low-bandwidth, 18-hour-a-day stream on the UK's digital terrestrial television (DTT) system in November 2005. Like The Box Plus Network and All Around
682-564: A rarity, found in an ever-dwindling number of markets. Analog television sets are accommodated, their tuners mostly obsolete and dependent entirely on the set-top box. Cable television is mostly available in North America , Europe , Australia , Asia and South America . Cable television has had little success in Africa , as it is not cost-effective to lay cables in sparsely populated areas. Multichannel multipoint distribution service ,

The cable company will provide set-top boxes based on the level of service a customer purchases, from basic set-top boxes with a standard-definition picture connected through the standard coaxial connection on the TV, to high-definition wireless digital video recorder (DVR) receivers connected via HDMI or component . Older analog television sets are cable ready and can receive
806-766: A series of signal amplifiers and line extenders. These devices carry the signal to customers via passive RF devices called taps. The very first cable networks were operated locally, notably in 1936 by Rediffusion in London in the United Kingdom and the same year in Berlin in Germany, notably for the Olympic Games , and from 1948 onwards in the United States and Switzerland. This type of local cable network
868-433: A sister network, Chart Shop TV , was launched. This network allowed viewers to purchase CDs and music-related merchandise. It aired on the same broadcast capacity as Chart Show, and aired from 4:00–6:00 am early in the morning during Chart Show's downtime. In March 2003, Chart Shop TV closed, and its broadcast capacity was used for Video Vault , once again broadcasting late-at-night during Chart Show TV's downtime. On 30 May
930-417: 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 plain old telephone service (POTS) to the company's switching center, where it is connected to the public switched telephone network ( PSTN ). The biggest obstacle to cable telephone service
992-605: A type F connector . The cable company's portion of the wiring usually ends at a distribution box on the building exterior, and built-in cable wiring in the walls usually distributes the signal to jacks in different rooms to which televisions are connected. Multiple cables to different rooms are split off the incoming cable with a small device called a splitter . There are two standards for cable television; older analog cable, and newer digital cable which can carry data signals used by digital television receivers such as high-definition television (HDTV) equipment. All cable companies in
1054-418: Is a British free-to-air children's television channel in the United Kingdom, owned by Narrative Entertainment UK Limited. As of June 2014, it broadcasts cartoons, sci-fi, action and adventure series and anime on Sky and on Freeview . Its target audience is 6 to 15-year-olds. At 6am on 19 May 2008, Pop +1 ceased broadcast and was directly replaced on-air with Kix content on Sky channel 627. Medabots
1116-399: Is a dedicated indie music channel. In 2008, they rebranded B4 to Flava after showing a mix of R&B music for a few months prior to this in March. The channel also went 16:9 widescreen prior to the rebrand, to match the other CSC music channels. On Tuesday 6 May, they launched Flaunt +1 , a 1-hour timeshifted version of Flaunt. This was their first-ever timeshifted music channel, and
1178-422: 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 telephone modem to provide for the upstream connection. This limited
1240-601: Is also the second to launch in the UK, after MTV One +1 (now MTV +1) launched in February 2008, replacing MTV Flux . On Monday 12 May, six days after launching their first music timeshift, Bliss +1 , their second music channel timeshift, was launched and their third music channel timeshift, Scuzz +1 launched in November 2008. It soon closed, and the satellite transponder space was then used by NHK World TV . On Monday 19 May, they launched their fourth kids channel, replacing Pop +1 . Kix! kit started at 06:00 hours, showing
1302-685: Is available. In August 2017, Kix rebranded its identity and is now under the Pop Max brand; however, its programming remained relatively unchanged. In June 2019, Pop Max moved to the G-MAN multiplex, meaning that Pop Max only broadcasts in Manchester on Freeview. In early 2022, a live Pop Max stream was added to the Freeview Play version of the Pop Player app. On 25 May 2022, Pop Max

#17327795225571364-482: 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 (QOS) demands of traditional analog plain old telephone service (POTS) service. The biggest advantage to digital cable telephone service is similar to the advantage of digital cable, namely that data can be compressed, resulting in much less bandwidth used than
1426-492: The DVB-C , DVB-C2 stream to IP for distribution of TV over IP network in the home. Many cable companies offer internet access through DOCSIS . In the most common system, multiple television channels (as many as 500, although this varies depending on the provider's available channel capacity) are distributed to subscriber residences through a coaxial cable , which comes from a trunkline supported on utility poles originating at
1488-616: The high band 7–13 of North American television frequencies . Some operators as in Cornwall, Ontario , used a dual distribution network with Channels 2–13 on each of the two cables. During the 1980s, United States regulations not unlike public, educational, and government access (PEG) created the beginning of cable-originated live television programming. As cable penetration increased, numerous cable-only TV stations were launched, many with their own news bureaus that could provide more immediate and more localized content than that provided by
1550-501: The Internet. Traditional cable television providers and traditional telecommunication companies increasingly compete in providing voice, video and data services to residences. The combination of television, telephone and Internet access is commonly called triple play , regardless of whether CATV or telcos offer it. More than 400,000 television service subscribers.

1612-595: The US for cable television and originally stood for community antenna television , from cable television's origins in 1948; in areas where over-the-air TV reception was limited by distance from transmitters or mountainous terrain, large community antennas were constructed, and cable was run from them to individual homes. In 1968, 6.4% of Americans had cable television. The number increased to 7.5% in 1978. By 1988, 52.8% of all households were using cable. The number further increased to 62.4% in 1994. To receive cable television at
1674-485: The United States have switched to or are in the course of switching to digital cable television since it was first introduced in the late 1990s. Most cable companies require a set-top box ( cable converter box ) or a slot on one's TV set for conditional access module cards to view their cable channels, even on newer televisions with digital cable QAM tuners, because most digital cable channels are now encrypted, or scrambled , to reduce cable service theft . A cable from
1736-505: The World Productions channels, all of CSC's music channels now broadcast 24 hours a day. In May 2012, CSC launched BuzMuzik , a new music television channel driven by mobile phone (text/mms) and social media. In February 2013, CSC launched True Entertainment +1, a one-hour timeshift of True Entertainment. It was replaced by True Drama on 4 June 2013. On 22 July 2013, Kix Power launched, replacing Pop Girl +1 on Sky. That
1798-449: The World Productions . In April 2014, CSC closed BuzMuzik, and replaced it with a revival of True Entertainment +1. The channel also closed for CSC to broadcast Starz TV. On 26 June 2014, Sony Pictures Television , Sony 's TV programming and network unit, said it would buy CSC and its 16 channels for £107 million ($ 180 million). The deal was completed on 15 August 2014. All the channels were transferred to Sony Pictures Television , and
1860-404: The basic selection. By subscribing to additional tiers, customers could get specialty channels, movie channels, and foreign channels. Large cable companies used addressable descramblers to limit access to premium channels for customers not subscribing to higher tiers, however the above magazines often published workarounds for that technology as well. During the 1990s, the pressure to accommodate
1922-563: The cable box itself, these midband channels were used for early incarnations of pay TV , e.g. The Z Channel (Los Angeles) and HBO but transmitted in the clear i.e. not scrambled as standard TV sets of the period could not pick up the signal nor could the average consumer de-tune the normal stations to be able to receive it. Once tuners that could receive select mid-band and super-band channels began to be incorporated into standard television sets, broadcasters were forced to either install scrambling circuitry or move these signals further out of

1984-429: The cable company's local distribution facility, called the headend . Many channels can be transmitted through one coaxial cable by a technique called frequency division multiplexing . At the headend, each television channel is translated to a different frequency . By giving each channel a different frequency slot on the cable, the separate television signals do not interfere with each other. At an outdoor cable box on
2046-515: The cable to send data from the customer box to the cable headend, for advanced features such as requesting pay-per-view shows or movies, cable internet access , and cable telephone service . The downstream channels occupy a band of frequencies from approximately 50 MHz to 1 GHz, while the upstream channels occupy frequencies of 5 to 42 MHz. Subscribers pay with a monthly fee. Subscribers can choose from several levels of service, with premium packages including more channels but costing
2108-675: The case of no local CBS or ABC station being available – rebroadcast the programming from a nearby affiliate but fill in with its own news and other community programming to suit its own locale. Many live local programs with local interests were subsequently created all over the United States in most major television markets in the early 1980s. This evolved into today's many cable-only broadcasts of diverse programming, including cable-only produced television movies and miniseries . Cable specialty channels , starting with channels oriented to show movies and large sporting or performance events, diversified further, and narrowcasting became common. By
2170-508: The chosen channel into the TV set on Channel 2, 3 or 4. Initially, UHF broadcast stations were at a disadvantage because the standard TV sets in use at the time were unable to receive their channels. With the passage of the All-Channel Receiver Act in 1964, all new television sets were required to include a UHF tuner, nonetheless, it would still take a few years for UHF stations to become competitive. Before being added to
2232-601: The company went dormant. On 13 December 2018, their four remaining music channels were sold to the TRACE Group . On 27 November 2019, the company was liquidated and dissolved. As of 2024, Pop, Pop +1, Pop Max and Pop Max +1 are the only CSC channels to still exist, as Tiny Pop became a digital service and the rest have closed, but did return in August, making second chance, at this time relaunched by Narrative Entertainment. Note: former channels in light red closed before
2294-578: The company's first children's network - Toons & Tunes soft-launched before fully launching as Pop in July. Video Vault would fully launch that month as The Vault, moving into Pop's broadcast capacity as a nighttime service. In September, a sister channel to Pop - Pop Plus, was launched, which functioned similarly to a timeshift service, although it didn't always air the same programmes as its sister channel. On 17 September The Vault moved out of Pop's capacity space and gained its own 24-hour slot. In July 2004,
2356-603: The company's next music channel B4 was launched in Pop Plus' broadcast capacity, broadcasting in its space at night. Pop Plus later re-launched as the pre-school-oriented Tiny Pop at the end of the month. In 2006, British Sky Broadcasting sold their three music channels Bliss (previously The Amp ), Scuzz , and Flaunt to CSC. Formerly encrypted, CSC made the channels FTA like the rest of their channels. In 2007, they launched five channels; two of which were timeshift channels : Pop +1 and Tiny Pop +1 . The third channel
2418-415: The fact that the descrambling circuitry was for a time present in these tuners, depriving the cable operator of much of their revenue, such cable-ready tuners are rarely used now – requiring a return to the set-top boxes used from the 1970s onward. The digital television transition in the United States has put all signals, broadcast and cable, into digital form, rendering analog cable television service
2480-457: The growing array of offerings resulted in digital transmission that made more efficient use of the VHF signal capacity; fibre optics was common to carry signals into areas near the home, where coax could carry higher frequencies over the short remaining distance. Although for a time in the 1980s and 1990s, television receivers and VCRs were equipped to receive the mid-band and super-band channels. Due to
2542-450: The headend, the electrical signal is translated into an optical signal and sent through the fiber. The fiber trunkline goes to several distribution hubs , from which multiple fibers fan out to carry the signal to boxes called optical nodes in local communities. At the optical node, the optical signal is translated back into an electrical signal and carried by coaxial cable distribution lines on utility poles, from which cables branch out to

2604-460: The jack in the wall is attached to the input of the box, and an output cable from the box is attached to the television, usually the RF-IN or composite input on older TVs. Since the set-top box only decodes the single channel that is being watched, each television in the house requires a separate box. Some unencrypted channels, usually traditional over-the-air broadcast networks, can be displayed without
2666-490: The late 1980s, cable-only signals outnumbered broadcast signals on cable systems, some of which by this time had expanded beyond 35 channels. By the mid-1980s in Canada, cable operators were allowed by the regulators to enter into distribution contracts with cable networks on their own. By the 1990s, tiers became common, with customers able to subscribe to different tiers to obtain different selections of additional channels above
2728-423: The maximum number of channels that could be broadcast in one city was 7: channels 2, 4, either 5 or 6, 7, 9, 11 and 13, as receivers at the time were unable to receive strong (local) signals on adjacent channels without distortion. (There were frequency gaps between 4 and 5, and between 6 and 7, which allowed both to be used in the same city). As equipment improved, all twelve channels could be utilized, except where
2790-451: The nearest network newscast. Such stations may use similar on-air branding as that used by the nearby broadcast network affiliate, but the fact that these stations do not broadcast over the air and are not regulated by the FCC, their call signs are meaningless. These stations evolved partially into today's over-the-air digital subchannels, where a main broadcast TV station e.g. NBC 37* would – in
2852-408: The old analog cable without a set-top box. To receive digital cable channels on an analog television set, even unencrypted ones, requires a different type of box, a digital television adapter supplied by the cable company or purchased by the subscriber. Another new distribution method that takes advantage of the low cost high quality DVB distribution to residential areas, uses TV gateways to convert
2914-504: The programming at the headend (the individual channels, which are distributed nationally, also have their own nationally oriented commercials). Modern cable systems are large, with a single network and headend often serving an entire metropolitan area . Most systems use hybrid fiber-coaxial (HFC) distribution; this means the trunklines that carry the signal from the headend to local neighborhoods are optical fiber to provide greater bandwidth and also extra capacity for future expansion. At
2976-454: The programming without cost. Later, the cable operators began to carry FM radio stations, and encouraged subscribers to connect their FM stereo sets to cable. Before stereo and bilingual TV sound became common, Pay-TV channel sound was added to the FM stereo cable line-ups. About this time, operators expanded beyond the 12-channel dial to use the midband and superband VHF channels adjacent to
3038-476: The range of reception for early cable-ready TVs and VCRs. However, once consumer sets had the ability to receive all 181 FCC allocated channels, premium broadcasters were left with no choice but to scramble. The descrambling circuitry was often published in electronics hobby magazines such as Popular Science and Popular Electronics allowing anybody with anything more than a rudimentary knowledge of broadcast electronics to be able to build their own and receive
3100-418: The signals are typically encrypted on modern digital cable systems, and the set-top box must be activated by an activation code sent by the cable company before it will function, which is only sent after the subscriber signs up. If the subscriber fails to pay their bill, the cable company can send a signal to deactivate the subscriber's box, preventing reception. There are also usually upstream channels on
3162-402: The start of Sony's deal. Cable television A cable channel (sometimes known as a cable network ) is a television network available via cable television. Many of the same channels are distributed through satellite television . Alternative terms include non-broadcast channel or programming service , the latter being mainly used in legal contexts. The abbreviation CATV is used in

At each television, the subscriber's television or a set-top box provided by the cable company translates the desired channel back to its original frequency ( baseband ), and it is displayed onscreen. Due to widespread cable theft in earlier analog systems,

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. In North America , Australia and Europe , many cable operators have already introduced cable telephone service, which operates just like existing fixed line operators. This service involves installing

The fourth channel was AnimeCentral , which time-shares with Pop Girl, and shows animated series for an older audience; it was the first dedicated channel in the UK for anime broadcasting. The fifth was Minx , which was a spin-off music channel from the Minx slot shown on Chart Show TV. Minx was later replaced by NME TV , which
3410-548: Was delisted from Freeview and was replaced with the Pop Player channel. On 5 July 2023 it was announced that Pop Max would return to Freeview under the local-TV multiplex on 19 July. In July 2013, Kix received Kix Power, which replaced Pop Girl +1 on Sky. Kix Power broadcast only Power Rangers . Kix Power was replaced by a Kix +1 service in October 2013, and this timeshift ran through October to November 2013. Kix Power
3472-427: Was limited, meaning frequencies over 250 MHz were difficult to transmit to distant portions of the coaxial network, and UHF channels could not be used at all. To expand beyond 12 channels, non-standard midband channels had to be used, located between the FM band and Channel 7, or superband beyond Channel 13 up to about 300 MHz; these channels initially were only accessible using separate tuner boxes that sent
3534-559: Was mainly used to relay terrestrial channels in geographical areas poorly served by terrestrial television signals. Cable television began in the United States as a commercial business in 1950s. The early systems simply received weak ( broadcast ) channels, amplified them, and sent them over unshielded wires to the subscribers, limited to a community or to adjacent communities. The receiving antenna would be taller than any individual subscriber could afford, thus bringing in stronger signals; in hilly or mountainous terrain it would be placed at

This timeshift was replaced with Pop +1 on 14 July 2014. In late 2013, CSC purchased Starz TV , which was a sole channel by Cloud Television One Limited, following the collapse of Mushroom TV and the sale of Mushroom's all other channels to All Around
3658-468: Was renamed to Kix. The labelling on the onscreen programme guide was changed in accordance with this. However, the Kix logo continued to include the exclamation mark until summer 2014. Kix broadcasts on Freeview since April 2016, following the earlier addition of Pop and Tiny Pop to the service. Until 2019, Kix transmitted on the same local-TV multiplex as Pop, so that Kix was only available in areas where Pop
