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.
109-572: Destination America is an American cable television channel owned by the Warner Bros. Discovery Networks unit of Warner Bros. Discovery . The network carries programming focused on the culture of the United States —including food, lifestyles, and travel. The network first launched in 1996 as Discovery Travel & Living Network , as part of a suite of four digital cable networks the company launched that year. From its launch until 2008,
218-501: A DEC Alpha –based computer for its VOD servers, allowing it to support more than a million users. By 1994 the Oracle scalable VOD system used massively parallel processors to support from 500 to 30,000 users. The SGI system supported 4,000 users. The servers connected to networks of increasing size to eventually support video stream delivery to entire cities. In the UK, from September 1994,
327-476: A blog focusing on sustainable living. The site was to be positioned as a digital companion to the new channel. In October 2007, Discovery hired veteran producer Andy Friendly as a consultant for Planet Green's programming, and to executive produce a series for the channel. The new series, Supper Club , was announced in January 2008, and would be hosted by Tom Bergeron (whom Friendly had helped cast as host for
436-563: A subscription model that requires users to pay a monthly fee for access to a selection of movies, television shows, and original series. In contrast, YouTube , another Internet-based VOD system, uses an advertising-funded model in which users can access most of its video content free of charge but must pay a subscription fee for premium content. Some airlines offer VOD services as in-flight entertainment to passengers through video screens embedded in seats or externally provided portable media players. Downloading and streaming VOD systems provide
545-575: A subscription business model in which subscribers are charged a regular fee to access unlimited programs. Examples of these services include Netflix , Hulu , Amazon Prime Video , Max , Disney+ , Peacock , Paramount+ , Apple TV+ , Disney+ Hotstar , iQIYI , Star+ , Hayu , BET+ , Discovery+ , Crunchyroll , SonyLIV , ZEE5 , and GulliMax . Near video on demand (NVOD) is a pay-per-view consumer video technique used by multi-channel broadcasters using high-bandwidth distribution mechanisms such as satellite and cable television. Multiple copies of
654-531: A 20-year deal to stream movies on demand over Enron's fiber-optic network. The heavily promoted deal failed, with Enron's share prices dropping following the announcement. In 1998, Kingston Communications became the first UK company to launch a fully commercial VOD service and the first to integrate broadcast television and Internet access through a single set-top box using IP delivery over ADSL. By 2001, Kingston Interactive TV had attracted 15,000 subscribers. After several trials, Home Choice followed in 1999 but
763-648: A VOD service formed a major part of the Cambridge Digital Interactive Television Trial. This provided video and data to 250 homes and several schools connected to the Cambridge Cable network, later part of NTL, now Virgin Media . The MPEG-1 encoded video was streamed over an ATM network from an ICL media server to set-top boxes designed by Acorn Online Media. The trial commenced at a speed of 2 Mbit/s to

VOD services were only made possible as a result of two major technological developments: MPEG ( motion-compensated DCT ) video compression and asymmetric digital subscriber line (ADSL) data transmission. Plans such as those of
981-1034: A darker and "uneasy" atmosphere (including a signature "glitch" effect) to reflect its change in programming direction. Discovery's 2018 acquisition of Scripps Networks Interactive brought Travel Channel back under its ownership; a rebranding of Travel Channel in October 2018 repositioned the network to focus more on paranormal programming. Since then, Destination America's schedule has largely shifted back towards its original format, drawing from Discovery and SNI's program libraries. Planet Green programming included ecologically themed shows built around celebrities including Ed Begley Jr. , Emeril Lagasse , Adrian Grenier , Leonardo DiCaprio , Ludacris , Tommy Lee , Tom Bergeron , SuChin Pak , Maria Menounos , Bob Woodruff, and Discovery Channel producer Tom Golden. In addition, celebrities gave 'green' tips within network bumpers that transitioned into and out of commercial breaks. The channel
1090-405: 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
1199-552: A few months. PVOD made a return during the COVID-19 pandemic and the resulting global closures of cinemas . Certain films that had already been released including The Invisible Man were quickly also released on VOD platforms for a higher rental price than usual, while other films including Trolls World Tour were released simultaneously on PVOD and in drive-in theaters , or in some cases directly to PVOD only. In most cases, these PVOD releases are offered through most of

#17327909737221308-543: 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),
1417-466: 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
1526-426: A launch planned for Spring 1995. At the time, the network had the working title Living and was described as "a home repair network". The launch was delayed, and the channel made its debut in October 1996, originally known as Discovery Travel & Living Network and offering programming including do-it-yourself projects, cooking , interior design and landscaping , and party planning. By 1998, it had settled on
1635-456: A legal peer-to-peer approach based on Kontiki technology to provide very-high-capacity multi-point downloads of the video content. Instead of the video content all being downloaded from Sky's servers, the content comes from multiple users of the system who have already downloaded the content. Other UK television broadcasters implemented their own versions of the same technology, such as Channel 4 's 4oD (4 on Demand, now known as All 4 ) which
1744-405: 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
1853-463: 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
1962-790: A piece of content once purchased via the Internet; and download to rent (DTR), by which customers can access the content for a limited time upon renting. Examples of TVOD services include the Apple iTunes Store and the Google Play Store, as well as VOD rental services offered through multichannel television (i.e., cable or satellite) providers. Premium video on demand (PVOD) is a version of TVOD which allows customers to access video-on-demand content several weeks or months earlier than their customary TVOD or home video availability – often feature films made available alongside, or in place of,
2071-415: A programme are broadcast at short time intervals (typically staggered on a schedule of every 10–20 minutes) on linear channels providing convenience for viewers, who can watch the programme without needing to tune in at the only scheduled point in time. A viewer may only have to wait a few minutes before the next time a movie will be programmed. This form is bandwidth-intensive, reduces the number of channels
2180-638: A provider can offer, and is generally provided by large operators with a great deal of redundant capacity. This concept has been reduced in popularity as video on demand is implemented, along with providers often wanting to provide the maximum throughput for their broadband services possible. Only the satellite services DirecTV and Dish Network continue to provide NVOD services, as they do not offer broadband and much of their rural customer base only has access to slower dial-up and non- 5G wireless and satellite internet options which cannot stream films or have onerous data caps (and where possible, AT&T
2289-564: 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 ,

#17327909737222398-455: A receiver box. 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
2507-703: 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
2616-414: A set-top box with a one-terabyte hard drive that could be used for video-on-demand services previously offered through cable television and broadband. A movie, for example, could be sent out once using a broadcast signal rather than numerous times over cable or fiber-optic lines, and this would not involve the expense of adding many miles of lines. Sezmi planned to lease part of the broadcast spectrum to offer
2725-417: 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
2834-433: A subscription service that National Association of Broadcasters President Gordon H. Smith said would provide a superior picture to that of cable or satellite at a lower cost. Developing VOD requires extensive negotiations to identify a financial model that would serve both content creators and cable providers while providing desirable content for viewers at an acceptable price point. Key factors identified for determining
2943-865: A subscription to the Disney+ streaming service, but they then retain access as long as they maintain their subscription (for Mulan , this was effectively a 90-day rental, as the film became available to all Disney+ subscribers at no extra charge in December). It has been reported that the pandemic had contributed to a transformation in movie distribution in favor of PVOD over traditional movie houses, as studios were able to realize 80% of revenue through PVOD versus 50% of traditional theater box office receipts. Theater owners including AMC and Cinemark, as well as suppliers including IMAX and National CineMedia, all experienced significant drops in revenues during shutdowns related to COVID-19. Subscription VOD ( SVOD ) services use
3052-475: A system of digital video recorders to simulate the video-on-demand experience. Most of Edge Spectrum's channels, where they are on air, carry televangelism . Push video on demand is so-named because the provider "pushes" the content out to the viewer's set-top box without the viewer having requested the content. This technique is used by several broadcasters on systems that lack the connectivity and bandwidth to provide true "streaming" video on demand. Push VOD
3161-411: A traditional release in movie theaters – but at a much higher price point. A version of the model was tested in 2011 by American satellite TV provider DirecTV under the brand name "Home Premiere", which allowed viewers to rent select films from major studios for US$ 30 per rental as soon as 60 days after they debuted in cinemas, compared to 120 days for the regular TVOD window; this version only lasted
3270-767: A user selects a video programme that begins to play immediately (i.e., streaming), or downloading to a DVR rented or purchased from the provider, or to a PC or to a portable device for deferred viewing. Streaming media has emerged as an increasingly popular medium of VOD provision over downloading, including BitTorrent . Desktop client applications such as the Apple iTunes online content store and Smart TV apps such as Amazon Prime Video allow temporary rentals and purchases of video entertainment content. Other Internet-based VOD systems provide users with access to bundles of video entertainment content rather than individual movies and shows. The most common of these systems, Netflix , Hulu , Disney+ , Peacock , Max and Paramount+ , use
3379-493: A user to view content. This technology also provides an advantage for technology companies for data analysis of viewed content from consumers. By analyzing data of what is viewed most by consumers, companies can purchase more content that is aimed for an audience, and then in-turn market products that are based on what viewer profiles are of a group of consumers who viewer a specific amount of content. This data analysis will often provide researchers valuable data that includes: what

3488-694: Is a cable VOD service that also offers pay-per-view. Once the programs have been downloaded onto a user's PVR, he or she can watch, play, pause, and seek at their convenience. VOD is also common in expensive hotels. According to the European Audiovisual Observatory , 142 paying VOD services were operational in Europe at the end of 2006. The number increased to 650 by 2009. At the 2010 Consumer Electronics Show in Las Vegas, Nevada , Sezmi CEO Buno Pati and president Phil Wiser showed
3597-603: Is a device that is Internet capable. Cable media companies have combined VOD with live streaming services. The early-2020s launches of apps from cable companies (e.g., NBC 's Peacock , CBS 's Paramount+ ) are attempts to compete with Subscription Video on Demand (SVOD) services because they lack live news and sports content. Streaming video servers can serve a wide community via a WAN , but responsiveness may be reduced. Download VOD services are practical in homes equipped with cable modems or DSL connections. Servers for traditional cable and telco VOD services are usually placed at

Alternative terms include non-broadcast channel or programming service , the latter being mainly used in legal contexts. The abbreviation CATV is used in 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
3924-422: 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

If the consumer requests one of these films, it is already loaded on her or his DVR. A push VOD system uses a personal video recorder (PVR) to store a selection of content, often transmitted in spare capacity overnight or all day long at low bandwidth. Users can watch

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

5559-485: 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 .

Television VOD systems can stream content, either through a traditional set-top box or through remote devices such as computers, tablets, and smartphones. VOD users may also permanently download content to a device such as a computer, digital video recorder (DVR) or, a portable media player for continued viewing. The majority of cable and telephone company –based television providers offer VOD streaming, whereby
5777-404: 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

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
5995-429: 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

In the telco world, they are placed in either the central office or a newly created location called a Video Head-End Office (VHO). VOD services first appeared in the early 1990s. Until then, it was not thought possible that a television programme could be squeezed into the limited telecommunication bandwidth of

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

Advertising video on demand (AVOD) uses an advertising-based revenue model. This allows companies that advertise on broadcast and cable channels to reach people who watch shows using VOD. This model also allows people to watch content without paying subscription fees. Hulu
6867-507: The economic viability of the VOD model include VOD movie buy-rates and setting Hollywood and cable operator revenue splits. Cable providers offered VOD as part of digital subscription packages, which by 2005 primarily allowed cable subscribers to only access an on-demand version of the content that was already provided in the linear traditional broadcasting distribution. These on-demand packages sometimes include extras and bonus footage in addition to

Video on demand can have three release strategies that include: day-and-date (instantaneous release in theaters and on VOD), day-before-date (VOD before theatrical viewing), and VOD only. Production studios can make revenue on these types of releases until sales start to slow. After that, film companies can then license
7194-457: 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

Both EchoStar / Dish Network and DirecTV offer VOD programming to PVR -owning subscribers of their satellite TV service. In Demand
7739-490: 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
7848-711: The latter two sources are declining due to streaming services offering much more lucrative performance contracts to performers, and several ring sports organisations (mainly UFC and WWE ) now prefer direct marketing of their product via streaming services such as ESPN+ , the WWE Network , and the apps of Fox Sports over pay-TV providers which require a portion of the profits they otherwise retain directly. In Australia, pay-TV broadcaster Foxtel offers NVOD for new-release movies over their satellite service.

7957-425: 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 a type F connector . The cable company's portion of
8066-423: 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
8175-736: The most common in the form of over-the-air television, VOD systems initially required each user to have an Internet connection with considerable bandwidth to access each system's content. In 2000, the Fraunhofer Institute IIS developed the JPEG2000 codec, which enabled the distribution of movies via Digital Cinema Packages. This technology has since expanded its services from feature-film productions to include broadcast television programmes and has led to lower bandwidth requirements for VOD applications. Disney , Paramount , Sony , Universal and Warner Bros. subsequently launched
8284-473: The name Discovery Home & Leisure , but the "Leisure" part of the name was dropped on March 29, 2004, when the channel became Discovery Home Channel . Much of the travel-related programming was dropped in the process to provide more focus on home improvement and cooking. In April 2007, during its upfronts , Discovery announced that Discovery Home would re-launch in 2008 as a new channel focused on environmentalism and sustainable living . The channel itself
8393-451: 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
8502-500: The network primarily focused upon home improvement , cooking , and leisure-themed programs. As of November 2023, Destination America is available to approximately 23,000,000 pay television households in the United States-down from its 2013 peak of 60,000,000 households. Along with American Heroes Channel , Boomerang , Cooking Channel , Discovery Family , Discovery Life , and Science Channel , Destination America
8611-826: The network, and 3DO as the set-top box with video streams and other information to be deployed to 2,500 homes. In 1994–95, US West filed for a patent concerning the provision of VOD in several cities: 330,000 subscribers in Denver, 290,000 in Minneapolis, and 140,000 in Portland. In early 1994, British Telecommunications (BT) introduced a trial VOD service in the United Kingdom. It used the DCT-based MPEG-1 and MPEG-2 video compression standards, along with ADSL technology. Many VOD trials were held with various combinations of server, network, and set-top box. Of these
8720-408: 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
8829-580: The other being the Oprah Winfrey Network —a relaunch of Discovery Health that was ultimately delayed to January 2011. Despite high expectations, the network's launch was unsuccessful; writing for NPR, Mark Hemingway observed that besides Focus Earth and Stuff Happens (praising the former as being "informative and shockingly fair to business interests"), the majority of Planet Green's programs involved either home renovations or "self-righteous" celebrities, and demonstrated that environmentalism
8938-519: The primary players in the US were the telephone companies using DEC, Microsoft, Oracle, IBM, Hewlett-Packard, USA Video, nCube, SGI, and other servers. The DEC server system was the most-used in these trials. The DEC VOD server architecture used interactive gateways to set up video streams and other information for delivery from any of a large number of VAX servers, enabling it in 1993 to support more than 100,000 streams with full videocassette recorder (VCR)-like functionality. In 1994, it upgraded to
9047-504: 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
9156-454: 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
9265-476: 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
9374-507: The regular content. Peer-to-peer (P2P) file-sharing software allows the distribution of content without the linear costs associated with centralised streaming media . This innovation proved it is technically possible to offer the consumer potentially every film ever made, and the popularity and ease of use of such services may have motivated the rise of centralised video-on-demand services. Some services such as Spotify use peer-to-peer distribution to better scale their platforms. Netflix
9483-489: The same platforms as traditional TVOD, but at a higher price point, typically about US$ 20 for a 48-hour rental; this offering has again been branded as "Home Premiere" by some studios and platforms. Disney used the September 2020 release of the live-action remake of Mulan to launch a related model called Premier Access ; this requires customers to pay a premium fee (approximately US$ 26–30 depending on country) on top of
9592-418: 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
9701-514: The start of the summer of 2012. On April 4, 2012, Discovery announced through the early release of an article in USA Today that Planet Green would be re-branded as Destination America, a network focusing primarily on cuisine, natural history, and travel programming, appealing primarily towards Middle America . The launch lineup also featured programs that had previously aired on Travel Channel before its sale to Cox Communications . The channel
9810-403: The subscriber's residence, the company's service drop cable is connected to cables distributing the signal to different rooms in the building. 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,
9919-532: The upstream speed to 31.2 Kbp/s 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. 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
10028-442: The user with features of portable media players and DVD players. Some VOD systems store and stream programs from hard disk drives and use a memory buffer to allow the user to fast-forward and rewind videos. It is possible to put video servers on local area networks ; these can provide rapid responses to users. Cable companies have rolled out their own versions of VOD services through apps, allowing television access wherever there
10137-460: The way for the seven Baby Bells— Ameritech , Bell Atlantic , BellSouth , NYNEX , Pacific Telesis , Southwestern Bell , and US West —to implement VOD systems. These companies and others began holding trials to set up systems for supplying video on demand over telephone and cable lines. In November 1992, Bell Atlantic announced a VOD trial. IBM was developing a video server code-named Tiger Shark. Concurrently, Digital Equipment Corporation (DEC)
10246-552: 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
10355-469: Was "pretty much a luxury item ". He felt that Emeril Green was "indistinguishable from much of what's already on the Food Network ", albeit with an emphasis on " buying local ". By March 2010, Planet Green's programming had broadened to include programs unrelated to its original concept , such as The Fabulous Beekman Boys . In February 2011, Discovery Communications executives were acknowledging
10464-487: Was a major AVOD company before ending its free service in August 2016, transferring it to Yahoo! View using the existing Hulu infrastructure. Crackle has introduced a series of advertisements for the same company that ties into the content that is being watched. Ad-Supported Video on Demand (ASVOD) refers to video services that provide free content supported by advertisements. Popular services include Pluto TV , Xumo ,
10573-689: Was announced as part of a $ 50 million corporate initiative known as " Planet Green ", undertaken under Discovery's new CEO David Zaslav , which would include the production of programming on other Discovery channels (such as the Discovery Channel series Ten Ways to Save the Planet ) that appeal to these themes, an "innovation conference", and making its headquarters carbon neutral . Zaslav stated that Discovery Home had been economically sound, but wasn't "serving this higher purpose". On August 1, 2007, Discovery announced its acquisition of TreeHugger ,
10682-420: Was announced that the network would launch on June 4, 2008, and that a "sneak peek" of the network's programming would become available via video on demand on April 17. Later that month, Planet Green ordered Focus Earth , a weekly environmental newsmagazine produced by ABC News and hosted by Bob Woodruff . Planet Green was one of the two highly anticipated Discovery network re-launches spearheaded by Zaslav,
10791-608: Was developing a scalable video server configured from small-to-large for a range of video streams. Bell Atlantic selected IBM and in April 1993 the system became the first VOD over ADSL to be deployed outside the lab, serving 50 video streams. In June 1993, US West filed for a patent to register a proprietary system consisting of the Digital Equipment Corporation Interactive Information Server, Scientific Atlanta providing
10900-469: Was launched on 16 November 2006 and the BBC's iPlayer , which was launched on 25 December 2007. Another example of online video publishers using legal peer-to-peer technology is based on Giraffic technology, which was launched in early 2011, with large online VOD publishers such as US-based VEOH and UK-based Craze's Online Movies Box movie rental service. Unlike broadcast television, which traditionally has been
11009-444: 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 a given location, cable distribution lines must be available on
11118-427: 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
11227-559: 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
11336-698: Was originally expected to have a Memorial Day launch on May 28, 2012. In 2015, the network began to experiment with professional wrestling by picking up TNA programming (which had recently been dropped by Spike ), including its flagship weekly program Impact Wrestling . Later that year, the network also announced that it had signed a 26-week television deal for Ring of Honor 's weekly show, Ring of Honor Wrestling , which would begin on June 3, 2015. Impact moved to Pop in January 2016. The network also began to increase its focus on programs dealing with paranormal topics and investigations; on October 30, 2015, it aired Exorcism Live —a live special broadcast from
11445-459: Was programmed in eight-hour blocks, which repeated three times per day until April 2010. Lacking separate satellite feeds for the East and West coasts of the United States, prime-time programs ran from 8 p.m. to 11 p.m. Eastern Time and were then repeated. Shows previously seen on Planet Green include: Cable television A cable channel (sometimes known as a cable network )
11554-442: Was reported to be considering switching to a P2P model to cope with net neutrality problems from downstream providers. Transactional video on demand (TVOD) is a distribution method by which customers pay for each piece of video-on-demand content. For example, a customer would pay a fee for each movie or TV show that they watch. TVOD has two sub-categories: electronic sell-through (EST), by which customers can permanently access
11663-537: Was restricted to London. After attracting 40,000 customers, they were bought by Tiscali in 2006 which was, in turn, bought by Talk Talk in 2009. Cable TV providers Telewest and NTL (now Virgin Media) launched their VOD services in the United Kingdom in 2005, competing with the leading traditional pay-TV distributor BSkyB , which responded by launching Sky by broadband , later renamed Sky Anytime on PC . The service went live on 2 January 2006. Sky Anytime on PC uses
11772-449: Was shut down due to a lack of funding. VOD services are now available in all parts of the United States, which has the highest global take-up rate of VOD. In 2010, 80% of American Internet users had watched video online, and 42% of mobile users who downloaded video preferred apps to a normal browser. Streaming VOD systems are available on desktop and mobile platforms from cable providers (in tandem with cable modem technology). They use
11881-448: Was watched, when it was watched, what they watched after watching, and even how many people watched the same video at the same time in a day, month, and even year. Economics of SVOD Attendance in movie theaters had declined during the 2020 COVID-19 pandemic. Worldwide in 2019, theatrical entertainment reach 11.4 billion dollars, but in 2020, it was only 2.2 billion. Due recovery efforts to increase those attendance numbers, along with
