Internet television (or online television) is the digital distribution of television content via the Internet. Internet television is a general term that covers the delivery of television shows and other video content over the Internet by video streaming technology, typically by major traditional television broadcasters, as opposed to traditional systems like terrestrial, cable and satellite, although internet itself is received by terrestrial, cable or satellite methods.
Internet television should not to be confused with Smart TV, IPTV or with Web TV. Smart TV refers to the TV set which has an inbuilt operating system. Internet Protocol television (IPTV) is one of the emerging Internet television technology standards for use by television broadcasters. Web television is a term used for programs created by a wide variety of companies and individuals for broadcast on Internet TV.
Technologies used for Internet television
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 (called HbbTV) for hybrid set-top boxes for the reception of broadcast and broadband digital television and multimedia applications with a single-user interface.
Current providers of Internet television use various technologies to provide a service such as peer-to-peer (P2P) technologies, 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 a standard http protocol. DRM (digital rights management) software is also incorporated into many Internet television services. Sky Go has software that is provided by Microsoft to prevent content being copied. Internet television is also cross platform, the Sky Player service has been expanded to the Xbox 360 on October 27[when?] and to Windows Media Center and then to Windows 7 PCs on November 19[when?]. The BBC iPlayer is also available through Virgin Media's on-demand service and other platforms such as FetchTV and games consoles including the Wii and the PlayStation 3. Other Internet-television platforms include mobile platforms such as the iPhone and iPod Touch, Nokia N96, Sony Ericsson C905 and many other mobile devices.
Samsung TV has also announced their plans to provide streaming options including 3D Video on Demand through their Explore 3D service.
Stream quality refers to the quality of the image and audio transferred from the servers of the distributor to the user's home screen.
Higher-quality video such as video in high definition (720p+) requires higher bandwidth and faster connection speeds. The generally accepted kbit/s download rate needed to stream high-definition video that has been encoded with 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 get 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 such a large scale.
For users which 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.
This diagnostic tool offered on the BBC iPlayer site measures a user's streaming capabilities and bandwidth for free.
Although competitors in the UK such as 4oD and Demand Five have not yet offered HD streaming, the technology to support it is fairly new and widespread HD streaming is not an impossibility. The availability of Channel 4 and Five content on YouTube is predicted to prove incredibly popular as series such as Skins, Green Wing, The X Factor and others become available in a simple, straightforward format on a website which already attracts millions of people every day.
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 vast popularity of smart TVs and devices such as the Roku and Chrome TV, 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 demand's 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 
Before 2006, most services used peer-to-peer (P2P) networking, in which users downloaded an application and data would be shared between the users rather than the service provider giving the now more commonly used streaming method. Now most service providers have moved away from the P2P systems and are now using the streaming media. The old P2P service was selected because the existing infrastructure could not handle the bandwidth necessary for centralized streaming distribution. Some consumers didn't like their upload bandwidth being consumed by their video player, which partially motivated the roll-out of centralized streaming distribution.
Launched in March 2012 in New York City (and subsequently stopped from broadcasting in June 2014), Aereo 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 Aero 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") 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.
Controlling content on the Internet presents a challenge for most providers; to try to ensure that a user is allowed to view content such as content with age certificates, providers use methods such as parental controls that allows restrictions to be placed upon the use and access of certificated material. The 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. Flagging systems can be used to warn a user that content may be certified or that it is intended for viewing post-watershed. Honor 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.
An archive is a collection of information and media much like a library or interactive-storage facility. It is a necessity for an on-demand media service to maintain archives so that users can watch content that has already been aired on standard-broadcast television. However, these archives can vary from a few weeks to months to years, depending on the curator and the type of content.
For example, the BBC iPlayer's shows are in general available for up to seven days after their original broadcast. This so-called "seven-day catch-up" model seems to become an industry standard for Internet television services in many countries around the world. However, some shows may only be available for shorter periods. Others, such as the BBC's Panorama, may be available for an extended period because of the show's documentary nature or its popularity.
In contrast, 4oD, Channel 4's on-demand service offers many of its television shows that were originally aired years ago. An example of this is the comedy The IT Crowd where users can view the full series on the Internet player. The same is true for other hit Channel 4 comedies such as The Inbetweeners and Black Books.
The benefit of large archives, is that they bring in far more users who, in turn, watch more media, leading to a wider audience base and more advertising revenue. Large archives will also mean the user will spend more time on that website rather than a competitors, leading to starvation of demand for the competitors.
Having an extensive archive, however, can bring problems along with benefits. Large archives are expensive to maintain, server farms and mass storage is needed along with ample bandwidth to transmit it all. Vast archives can be hard to catalogue and sort so that it is accessible to users.
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 4oD 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.
An increasing trend among major content producers in North America 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.
Profits and costs
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 adverstise and charge a monthly fee. Other such as netflix and amazon charge a monthly fee and have no commercials. Netflix is the largest provider with over 43 million members and growing. The rise of internet TV has resulted in Cable Companies losing customer to a new kind of customer called "Cord Cutters" these cord cutters are forming communities and proving a solid alternative to cable and satellite television. Most of the cable cutters are younger and have opted to not sign up for traditional cable service.
