Video on demand ( VOD ) is a media distribution system that allows users to access videos, television shows and films digitally on request. These multimedia are accessed without a traditional video playback device and a typical static broadcasting schedule, which was popular under traditional broadcast programming , instead involving newer modes of content consumption that have risen as Internet and IPTV technologies have become prominent, and culminated in the arrival of VOD and over-the-top (OTT) media services on televisions and personal computers .
87-511: Voyo is a Czech paid video on demand service launched in 2011 as a free archive of programs produced by every national TV channel owned by CME and a platform for live broadcasting of original work and sports broadcasts. It gradually transformed into a paid service modeled after the American Netflix . The range of available programs is regularly changed. According to the operator, there are more than 2,000 movies and series. The vast majority of
174-494: 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,
261-488: A router and a DHCP server to provide the LAN with IP network addressing. From a data forwarding and network topology perspective, this router functionality is typically kept distinct from the cable modem functionality (at least logically) even though the two may share a single enclosure and appear as one unit, sometimes called a residential gateway . So, the cable modem function will have its own IP address and MAC address as will
348-563: 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
435-575: 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
522-531: 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
609-445: A DOCSIS modem, but the company filed for bankruptcy in 2003 and closed. The DOCSIS CMTS assets of COM21 were acquired by ARRIS . CDLP was a proprietary system manufactured by Motorola . CDLP customer premises equipment (CPE) was capable of both PSTN (telephone network) and radio frequency (cable) return paths. The PSTN-based service was considered 'one-way cable' and had many of the same drawbacks as satellite Internet service; as

#17328581412911044-586: A hardware version of the modem, instead of simply allowing a supported DOCSIS version. In 2004, the Multimedia over Coax Alliance (MoCA) was established to develop industry standard for the connected home, using the existing coaxial cabling. Initially developed for in-home networking with MoCA 1.0/1.1, the MoCA standards has continued to develop with MoCA 2.0/2.1 in 2010 and MoCa 2.5 in 2016. In 2017, Multimedia over Coax Alliance introduced MoCA Access specification, based on
1131-456: 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
1218-773: 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,
1305-415: 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
1392-638: 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
1479-497: A result, it quickly gave way to "two-way cable." Cable modems that used the RF cable network for the return path were considered 'two-way cable', and were better able to compete with the bi-directional digital subscriber line (DSL) service. The standard is in little use now as new providers use, and existing providers having changed to, the DOCSIS standard. The Motorola CDLP proprietary CyberSURFR
1566-414: 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
1653-487: A single cable modem to use concurrently more than one upstream channel and more than one downstream channel in parallel. Virtually all cable modems operating in the field today are compliant with one of the DOCSIS versions. Because of the differences in the European PAL and US's NTSC systems two main versions of DOCSIS exist, DOCSIS and EuroDOCSIS. The main differences are found in the width of RF-channels: 6 MHz for
1740-433: 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
1827-856: 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

Video on demand 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
2088-411: 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
2175-767: 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
2262-493: 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
2349-672: 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
2436-603: 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
2523-417: Is a type of network bridge that provides bi-directional data communication via radio frequency channels on a hybrid fiber-coaxial (HFC), radio frequency over glass (RFoG) and coaxial cable infrastructure. Cable modems are primarily used to deliver broadband Internet access in the form of cable Internet , taking advantage of the high bandwidth of a HFC and RFoG network. They are commonly deployed in
2610-435: Is also used by broadcasters that want to optimize their video streaming infrastructures by pre-loading the most popular contents to the consumers' set-top device. 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
2697-447: Is an example of a device that was built to the CDLP standard, capable of a peak 10 Mbit/s downstream and 1.532 Mbit/s upstream. CDLP supported a maximum downstream bandwidth of 30 Mbit/s which could be reached by using several cable modems. The Australian ISP BigPond employed this system when it started cable modem tests in 1996. For a number of years cable Internet access

In the transport layer the cable modem supports UDP in association with its own IP address, and it supports filtering based on TCP and UDP port numbers to, for example, block forwarding of NetBIOS traffic out of the customer's LAN. In the Application Layer , the cable modem supports certain protocols that are used for management and maintenance, notably Dynamic Host Configuration Protocol (DHCP), SNMP , and TFTP . Some cable modems may incorporate

In a reflection made by 2013 Netflix Chief Content Officer, Ted Sarandos , he was quoted saying, "When we launch in a territory the BitTorrent traffic drops as the Netflix traffic grows." This can be valuably interpreted as in that online piracy numbers drop the more that SVOD companies grow, which in turn means more revenue going back to
4437-447: The downloaded content at the time they desire, immediately and without any buffering issues. Push VOD depends on the viewer recording content so choices can be limited. 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

4698-483: The first high-speed, asymmetrical cable modem system in 1990. A key Hybrid Networks insight was that in the nascent days of the Internet, data downloading constitutes the majority of the data traffic, and this can be served adequately with a highly asymmetrical data network (i.e. a large downstream data pipe and many small upstream data pipes). This allowed CATV operators to offer high-speed data services immediately without first requiring an expensive system upgrade. Also key

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

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
6090-492: The router. Cable modems can have a problem known in industry jargon as "flap" or "flapping". A modem flap is when the connection by the modem to the head-end has been dropped (gone offline) and then comes back online. The time offline or rate of flap is not typically recorded, only the incidence. While this is a common occurrence and usually unnoticed, if a modem's flap is extremely high, these disconnects can cause service to be disrupted. If there are usability problems due to flap
6177-484: 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
6264-624: The time had formed a joint-venture with Antec called ARRIS Interactive. Because of contractual agreements with Antec involving this joint venture, Nortel spun the LANCity group out into the ARRIS Interactive joint-venture. ARRIS continues to make cable modems and cable modem termination system (CMTS) equipment compliant with the DOCSIS standard. Zenith offered a cable modem technology using its own protocol which it introduced in 1993, being one of
6351-460: The typical cause is a defective modem or very high amounts of traffic on the service provider's network (upstream utilization too high). Types of flap include reinsertions, hits and misses, and power adjustments. In January 2020, a vulnerability affecting cable modems using Broadcom chipsets was disclosed and named Cable Haunt . Security researchers say that the vulnerability affects hundreds of millions of devices. Exploits are possible because of
6438-469: The upstream as well as the downstream path. Hybrid's system architecture is used for most cable modem systems today. LANcity was an early pioneer in cable modems, developing a proprietary system that was widely deployed in the U.S. LANcity, which was led by the Iranian-American engineer Rouzbeh Yassini , was then acquired by Bay Networks . Bay Networks was subsequently acquired by Nortel . Nortel at
6525-442: 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
6612-460: 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)
6699-483: 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 ,
6786-645: Was another early pioneer in cable modems, and quite successful until proprietary systems were made obsolete by the DOCSIS standardization. The Com21 system used a ComController as the central bridge in CATV network head-ends, the ComPort cable modem in various models and the NMAPS management system using HP OpenView as the platform. Later they also introduced a return path multiplexer to overcome noise problems when combining return path signals from multiple areas. The proprietary protocol
6873-453: Was based on Asynchronous Transfer Mode (ATM). The central ComController switch was a modular system offering one downstream channel (transmitter) and one management module. The remaining slots could be used for upstream receivers (2 per card), dual Ethernet 10BaseT and later also Fast-Ethernet and ATM interfaces. The ATM interface became the most popular, as it supported the increasing bandwidth demands and also supported VLANs . Com21 developed
6960-582: 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
7047-466: 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
7134-665: Was only available in Sydney , Melbourne and Brisbane via CDLP. This network ran parallel to the newer DOCSIS system for several years. In 2004, the CDLP network was terminated and replaced by DOCSIS. CDLP has been also rolled out at the French cable operator Numericable before upgrading its IP broadband network using DOCSIS. Digital Video Broadcasting ( DVB ) and Digital Audio Visual Council (DAVIC) are European-formed organizations that developed some cable modem standards. However, these standards have not been as widely adopted as DOCSIS. In
7221-442: 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
7308-533: 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
7395-449: 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
7482-464: Was that it saw that the upstream and downstream communications could be on the same or different communications media using different protocols working in each direction to establish a closed-loop communications system. The speeds and protocols used in each direction would be very different. The earliest systems used the public switched telephone network (PSTN) for the return path since very few cable systems were bi-directional. Later systems used CATV for
7569-448: 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
