Streaming television is the digital distribution of television content, such as TV shows, as streaming video delivered over the Internet. Streaming TV stands in contrast to dedicated terrestrial television delivered by over-the-air aerial systems, cable television, and/or satellite television systems. The use of streaming online video and web television by consumers has seen a dramatic increase ever since the launch of online video platforms such as YouTube and Netflix.[ citation needed ]
It is also known as streaming TV, online TV, Internet TV, or TV streaming.
Up until the 1990s, it was not thought possible that a television programme could be squeezed into the limited telecommunication bandwidth of a copper telephone cable to provide a streaming service of acceptable quality, as the required bandwidth of a digital television signal was around 200 Mbps, which was 2,000 times greater than the bandwidth of a speech signal over a copper telephone wire.
Streaming services were only made possible as a result of two major technological developments: discrete cosine transform (DCT) video compression and asymmetric digital subscriber line (ADSL) data transmission. kbps to 2 Mbps, while DCT compression reduced the required bandwidth of a digital television signal from around 200 Mbps down to about 2 Mpps. The combination of DCT and ADSL technologies made it possible to practically implement streaming services at around 2 Mbps bandwidth.DCT is a lossy compression technique that was first proposed by Nasir Ahmed in 1972, and was later adapted into a motion-compensated DCT algorithm for video coding standards such as the H.26x formats from 1988 onwards and the MPEG formats from 1991 onwards. Motion-compensated DCT video compression significantly reduced the amount of bandwidth required for a television signal, while at the same time ADSL increased the bandwidth of data that could be sent over a copper telephone wire. ADSL increased the bandwidth of a telephone line from around 100
The mid-2000s were the beginning of television programs becoming available via the Internet. The video-sharing site YouTube was launched in early 2005, allowing users to share illegally posted television programs.YouTube co-founder Jawed Karim said the inspiration for YouTube first came from Janet Jackson's role in the 2004 Super Bowl incident, when her breast was exposed during her performance, and later from the 2004 Indian Ocean tsunami. Karim could not easily find video clips of either event online, which led to the idea of a video sharing site.
Apple's iTunes service also began offering select television programs and series in 2005, available for download after direct payment.A few years later, television networks and other independent services began creating sites where shows and programs could be streamed online. Amazon Video began in the United States as Amazon Unbox in 2006, but did not launch worldwide until 2016. Netflix, a website originally created for DVD rentals and sales, began providing streaming content in 2007. In 2008 Hulu, owned by NBC and Fox, was launched, followed by tv.com in 2009, owned by CBS. Digital media players also began to become available to the public during this time. The first generation Apple TV was released in 2007 and in 2008 the first generation Roku streaming device was announced.
Smart TVs took over the television market after 2010 and continue to partner with new providers to bring streaming video to even more users.As of 2015 smart TVs are the only type of middle to high-end television being produced. Amazon's version of a digital media player, Amazon Fire TV, was not offered to the public until 2014.
These digital media players have continued to be updated and new generations released. Access to television programming has evolved from computer and television access, to also include mobile devices such as smartphones and tablet computers. Apps for mobile devices started to become available via app stores in 2008. These mobile apps allow users to view content on mobile devices that support the apps. After 2010 traditional cable and satellite television providers began to offer services such as Sling TV, owned by Dish Network, which was unveiled in January 2015.DirecTV, another satellite television provider launched their own streaming service, DirecTV Now, in 2016. Similarly in the UK, Sky launched a streaming service called Now TV.
In 2017 YouTube launched YouTube TV, a streaming service that allows users to watch live television programs from popular cable or network channels, and record shows to stream anywhere, anytime.As of 2017, 28% of US adults cite streaming services as their main means for watching television, and 61% of those ages 18 to 29 cite it as their main method. As of 2018, Netflix is the world's largest streaming TV network and also the world's largest Internet media and entertainment company with 117 million paid subscribers, and by revenue and market cap.
The Hybrid Broadcast Broadband TV (HbbTV) consortium of industry companies (such as SES, Humax, Philips, and ANT Software) is currently promoting and establishing an open European standard for hybrid set-top boxes for the reception of broadcast and broadband digital television and multimedia applications with a single-user interface.
As of the 2010s, providers of Internet television use various technologies to provide VoD systems and live streaming. BBC iPlayer makes use of the Adobe Flash Player to provide streaming-video clips and other software provided by Adobe for its download service. CNBC, Bloomberg Television and Showtime use live-streaming services from BitGravity to stream live television to paid subscribers using the HTTP protocol.
BBC iPlayer originally incorporated peer-to-peer streaming, moved towards centralized distribution for their video streaming services. BBC executive Anthony rose cited network performance as an important factor in the decision, as well as the unhappiness among consumers unhappy with their own network bandwidth being consumed for transmitting content to other viewers.
Samsung TV has also announced their plans to provide streaming options including 3D Video on Demand through their Explore 3D service.
Some streaming services incorporate digital rights management. The W3C made the controversial decision to adopt Encrypted Media Extensions due in large part to motivations to provide copy protection for streaming content. Sky Go has software that is provided by Microsoft to prevent content being copied.
Additionally, BBC iPlayer makes use of a parental control system giving parents the option to "lock" content, meaning that a password would have to be used to access it. The goal of these systems is to enable parents to keep children from viewing sexually-themed, violent, or otherwise inappropriate material. Flagging systems can be used to warn a user that content may be certified or that it is intended for viewing post-watershed. Honour systems are also used where users are asked for their dates of birth or age to verify if they are able to view certain content.
IPTV delivers television content using signals based on the Internet protocol (IP), through the open, unmanaged Internet with the "last-mile" telecom company acting only as the Internet service provider (ISP). As described above, "Internet television" is "over-the-top technology" (OTT). Both IPTV and OTT use the Internet protocol over a packet-switched network to transmit data, but IPTV operates in a closed system—a dedicated, managed network controlled by the local cable, satellite, telephone, or fiber-optic company.In its simplest form, IPTV simply replaces traditional circuit switched analog or digital television channels with digital channels which happen to use packet-switched transmission. In both the old and new systems, subscribers have set-top boxes or other customer-premises equipment that communicates directly over company-owned or dedicated leased lines with central-office servers. Packets never travel over the public Internet, so the television provider can guarantee enough local bandwidth for each customer's needs.
The Internet protocol is a cheap, standardized way to enable two-way communication and simultaneously provide different data (e.g., TV-show files, email, Web browsing) to different customers. This supports DVR-like features for time shifting television: for example, to catch up on a TV show that was broadcast hours or days ago, or to replay the current TV show from its beginning. It also supports video on demand—browsing a catalog of videos (such as movies or television shows) which might be unrelated to the company's scheduled broadcasts.
IPTV has an ongoing standardization process (for example, at the European Telecommunications Standards Institute).
|Content provider||Local telecom||Studio, channel, or independent service|
|Transmission network||Local telecom - dedicated owned or leased network||Public Internet + local telecom|
|Receiver||Local telecom provides (set-top box)||Purchased by consumer (box, stick, TV, computer, or mobile)|
|Display device||Screen provided by consumer||Screen provided by consumer|
|Examples||AT&T U-verse, Bell Fibe TV, Verizon Fios (IPTV service now discontinued)||Video on demand services like fuboTV, PlayStation Vue, Sky Go, YouTube, Netflix, Amazon, DittoTV, YuppTV, Lovefilm, BBC iPlayer, Hulu, Sony Liv, myTV, Now TV, Emagine, SlingTV, KlowdTV|
Streaming quality is the quality of image and audio transmission from the servers of the distributor to the user's screen. High-definition video (720p+) and later standards require higher bandwidth and faster connection speeds than previous standards, because they carry higher spatial resolution image content. In addition, transmission packet loss and latency caused by network impairments and insufficient bandwidth degrade replay quality. Decoding errors may manifest themselves with video breakup and macro blocks. The generally accepted download rate for streaming high-definition video encoded in H.264 is 3500 kbit/s, whereas standard-definition television can range from 500 to 1500 kbit/s depending on the resolution on screen. In the UK, the BBC iPlayer deals with the largest amount of traffic yet it offers HD content along with SD content. As more people have gotten broadband connections which can deal with streaming HD video over the Internet, the BBC iPlayer has tried to keep up with demand and pace. However, as streaming HD video takes around 1.5 GB of data per hour of video the BBC has had to invest a lot of money collected from License Fee payers to implement this on a large scale.
For users who do not have the bandwidth to stream HD video or even high-SD video, which requires 1500 kbit/s, the BBC iPlayer offers lower bitrate streams which in turn lead to lower video quality. This makes use of an adaptive bitrate stream so that if the user's bandwidth suddenly drops, iPlayer will lower its streaming rate to compensate. A diagnostic tool offered on the BBC iPlayer site measures a user's streaming capabilities and bandwidth.
Internet television is common in most US households as of the mid 2010s. About one in four new televisions being sold is now a smart TV.
Considering the popularity of smart TVs and devices such as the Roku and Chromecast, much of the US public can watch television via the Internet. Internet-only channels are now established enough to feature some Emmy-nominated shows, such as Netflix's House of Cards .Many networks also distribute their shows the next day to streaming providers such as Hulu Some networks may use a proprietary system, such as the BBC utilizes their iPlayer format. This has resulted in bandwidth demands increasing to the point of causing issues for some networks. It was reported in February 2014 that Verizon is having issues coping with the demand placed on their network infrastructure. Until long-term bandwidth issues are worked out and regulation such at net neutrality Internet Televisions push to HDTV may start to hinder growth.
Aereo was launched in March 2012 in New York City (and subsequently stopped from broadcasting in June 2014). It streamed network TV only to New York customers over the Internet. Broadcasters filed lawsuits against Aereo, because Aereo captured broadcast signals and streamed the content to Aereo's customers without paying broadcasters. In mid-July 2012, a federal judge sided with the Aereo start-up. Aereo planned to expand to every major metropolitan area by the end of 2013.The Supreme Court ruled against Aereo June 24, 2014.
Many providers of Internet television services exist—including conventional television stations that have taken advantage of the Internet as a way to continue showing television shows after they have been broadcast, often advertised as "on-demand" and "catch-up" services. Today, almost every major broadcaster around the world is operating an Internet television platform.Examples include the BBC, which introduced the BBC iPlayer on 25 June 2008 as an extension to its "RadioPlayer" and already existing streamed video-clip content, and Channel 4 that launched 4oD ("4 on Demand") (now All 4) in November 2006 allowing users to watch recently shown content. Most Internet television services allow users to view content free of charge; however, some content is for a fee.
Since 2012, around 200 over-the-top (OTT) platforms providing streamed and downloadable content have emerged.Investment by Netflix in new original content for its OTT platform reached $13bn in 2018.
Broadcasting rights vary from country to country and even within provinces of countries. These rights govern the distribution of copyrighted content and media and allow the sole distribution of that content at any one time. An example of content only being aired in certain countries is BBC iPlayer. The BBC checks a user's IP address to make sure that only users located in the UK can stream content from the BBC. The BBC only allows free use of their product for users within the UK as those users have paid for a television license that funds part of the BBC. This IP address check is not foolproof as the user may be accessing the BBC website through a VPN or proxy server. Broadcasting rights can also be restricted to allowing a broadcaster rights to distribute that content for a limited time. Channel 4's online service All 4 can only stream shows created in the US by companies such as HBO for thirty days after they are aired on one of the Channel 4 group channels. This is to boost DVD sales for the companies who produce that media.
Some companies pay very large amounts for broadcasting rights with sports and US sitcoms usually fetching the highest price from UK-based broadcasters. A trend among major content producers in North America [ when? ] is the use of the "TV Everywhere" system. Especially for live content, the TV Everywhere system restricts viewership of a video feed to select Internet service providers, usually cable television companies that pay a retransmission consent or subscription fee to the content producer. This often has the negative effect of making the availability of content dependent upon the provider, with the consumer having little or no choice on whether they receive the product.
With the advent of broadband Internet connections, multiple streaming providers have come onto the market in the last couple of years. The main providers are Netflix, Hulu and Amazon. Some of these providers such as Hulu advertise and charge a monthly fee. Other such as Netflix and Amazon charge users a monthly fee and have no commercials. Netflix is the largest provider; it has over 130 million members and its membership numbers are growing.[ when? ] The rise of internet TV has resulted in cable companies losing customers to a new kind of customer called "cord cutters". Cord cutters are consumers who are cancelling their cable TV or satellite TV subscriptions and choosing instead to stream TV shows, movies and other content via the Internet. Cord cutters are forming communities. With the increasing availability of video sharing websites (e.g., YouTube) and streaming services, there is an alternative to cable and satellite television subscriptions. Cord cutters tend to be younger people.

Streaming media is multimedia that is constantly received by and presented to an end-user while being delivered by a provider. The verb to stream refers to the process of delivering or obtaining media in this manner. Streaming refers to the delivery method of the medium, rather than the medium itself. Distinguishing delivery method from the media distributed applies specifically to telecommunications networks, as most of the delivery systems are either inherently streaming or inherently non-streaming. There are challenges with streaming content on the Internet. For example, users whose Internet connection lacks sufficient bandwidth may experience stops, lags, or slow buffering of the content. And users lacking compatible hardware or software systems may be unable to stream certain content.
Video on demand (VOD) is a media distribution system that allows users to access videos without a traditional video playback device and the constraints of a typical static broadcasting schedule. In the 20th century, broadcasting in the form of over-the-air programming was the most common form of media distribution. As Internet and IPTV technologies continued to develop in the 1990s, consumers began to gravitate towards non-traditional modes of content consumption, which culminated in the arrival of VOD on televisions and personal computers.
Interactive television is a form of media convergence, adding data services to traditional television technology. Throughout its history, these have included on-demand delivery of content, as well as new uses such as online shopping, banking, and so forth. Interactive TV is a concrete example of how new information technology can be integrated vertically rather than laterally.
A home theater PC (HTPC) or media center computer is a convergent device that combines some or all the capabilities of a personal computer with a software application that supports video, photo, audio playback, and sometimes video recording functionality. In recent years, other types of consumer electronics, including game consoles and dedicated media devices, have crossed over to manage video and music content. The term "media center" also refers to specialized application software designed to run on standard personal computers.
Internet Protocol television (IPTV) is the delivery of television content over Internet Protocol (IP) networks. This is in contrast to delivery through traditional terrestrial, satellite, and cable television formats. Unlike downloaded media, IPTV offers the ability to stream the source media continuously. As a result, a client media player can begin playing the content almost immediately. This is known as streaming media.
Web television is original episodic online video content produced for broadcast on the Internet via the World Wide Web. The phrase "web television" is also sometimes used to refer to Internet television in general, which includes Internet-transmission of programs produced for both online and traditional terrestrial, cable, or satellite broadcast.
Multichannel television in the United States has been available since at least 1948. The United States is served by multichannel television through cable television systems, direct-broadcast satellite providers, and various other wireline video providers; among the largest television providers in the U.S. are AT&T, Altice USA, Charter Communications, Comcast, Dish Network, and Verizon Communications. The Telecommunications Act of 1996 defines a multichannel video programming distributor (MVPD) as "a person such as, but not limited to, a cable operator, a multichannel multipoint distribution service, a direct broadcast satellite service, or a television receive-only satellite program distributor, who makes available for purchase, by subscribers or customers, multiple channels of video programming", where a channel is defined as a "signaling path provided by a cable television system."
Internet television in Australia is the digital distribution of movies and television content via the Internet. In Australia, internet television is provided by a number of generalist, subscription-based streaming service providers, in addition to several niche providers that focus on specific genres. Australia's five major free-to-air television networks also all offer catch up TV of previously broadcast content to watch via their webpages and apps, and a number of ISPs and other companies offer IPTV – the live streaming of television channels sourced from Australia and elsewhere.
VMedia Inc. is a Canadian telecommunications company and broadcast distribution provider. It offers VoIP telephone and home security services across Canada; DSL and cable Internet in Ontario, Quebec, Manitoba, Saskatchewan, Alberta, and British Columbia; and IPTV television service in Ontario, Quebec, Alberta and British Columbia.
TV Everywhere refers to a business model wherein access to streaming video content from a television channel requires users to "authenticate" themselves as current subscribers to the channel, via an account provided by their participating pay television provider, in order to access the content.
A Smart TV, also known as a connected TV (CTV), is a traditional television set with integrated Internet and interactive Web 2.0 features which allows users to stream music and videos, browse the internet, and view photos. Smart TV is a technological convergence of computers, television sets and set-top boxes. Besides the traditional functions of television sets and set-top boxes provided through traditional broadcasting media, these devices can also provide Internet TV, online interactive media, over-the-top content (OTT), as well as on-demand streaming media, and home networking access.
An over-the-top (OTT) media service is a streaming media service offered directly to viewers via the Internet. OTT bypasses cable, broadcast, and satellite television platforms, the companies that traditionally act as a controller or distributor of such content. It has also been used to describe no-carrier cellphones, where all communications are charged as data, avoiding monopolistic competition, or apps for phones that transmit data in this manner, including both those that replace other call methods and those that update software.
Aereo was a technology company based in New York City that allowed subscribers to view live and time-shifted streams of over-the-air television on Internet-connected devices. The service opened to customers in March 2012, and was backed by Barry Diller's IAC.
Access-independent service (AIS) is a service concept in which a service does not depend on guaranteed access network cooperation for service delivery. Telecoms industry analyst Dean Bubley first used the term in a report on Telco-OTT in February 2012.
An online video platform (OVP), provided by a video hosting service, enables users to upload, convert, store and play back video content on the Internet, often via a structured, large-scale system that may generate revenue. Users generally will upload video content via the hosting service's website, mobile or desktop application, or other interface (API). The type of video content uploaded might be anything from shorts to full-length TV shows and movies. The video host stores the video on its server and offers users the ability to enable different types of embed codes or links that allow others to view the video content. The website, mainly used as the video hosting website, is usually called the video sharing website.
In broadcast television, cord-cutting refers to the pattern of viewers, referred to as cord-cutters, cancelling their subscriptions to multichannel television services available over cable or satellite, dropping pay television channels or reducing the number of hours of subscription TV viewed in response to competition from rival media available over the Internet. This content is either free or significantly cheaper than the same content provided via cable.
Sling TV is an American streaming television service operated by Sling TV LLC, a wholly owned subsidiary of Dish Network. Unveiled on January 5, 2015, at the Consumer Electronics Show, the virtual multichannel video programming distributor aims to complement subscription video on demand services for cord cutters, offering a selection of major cable channels and OTT-originated services that can be streamed through smart TVs, digital media players and apps. The service is available in the United States and Puerto Rico as of 2015.
A Media Aggregation Platform or Media Aggregation Portal (MAP) is an over the top service for distributing web-based streaming media content from multiple sources to a large audience. MAPs consist of networks of sources who host their own content which viewers can choose and access directly from a larger variety of content to choose from than a single source can offer. The service is used by content providers, looking to extend the reach of their content.
A streaming service provider is a subscription-based service offering online streaming of films and television programs. Most of these services are owned by a major film studio. The streaming services started as an add-on to Blu-ray offerings, which are supplements to the programs watched.
Live streaming world news refers to live videos streams of world television news which are provided via streaming television or via streaming media by various television networks and television news outlets, from various countries. These are provided through Smart TV, or else through the networks' own websites, or also possibly via internet television, especially YouTube, or via video on demand services, subscription video on demand websites such as e.g. Hulu, mobile apps, or digital media players that are designed to play streaming television, such as e.g. the Roku media player.
