LG Electronics smart TV from 2011

A smart TV, also known as a connected TV (CTV), is a traditional television set with integrated Internet and interactive Web 2.0 features that allow users to stream music and videos, browse the internet, and view photos. Smart TVs are a technological convergence of computers, televisions, and digital media players. Besides the traditional functions of television sets provided through traditional broadcasting media, these devices can provide access to over-the-top media services such as streaming television and internet radio, along with home networking access.[1][2][3]

Smart TV should not be confused with Internet TV,

IPTV, or streaming television
. Internet TV refers to receiving television content over the Internet instead of traditional systems such as terrestrial, cable, and satellite, regardless of how the Internet is delivered. IPTV is one of the Internet television technology standards for use by television broadcasters. Streaming television is a term used for programs created by many producers for showing on Internet TV.

In smart TVs, the

application store or marketplace, in a similar manner to how applications are integrated into modern smartphones.[4][5][6][7][8]

The technology that enables smart TVs is also incorporated into external devices such as

satellite TV
channels, or a local storage device.

Definition

Smart TVs on display

A Smart TV device is either a television set with integrated Internet capabilities or a set-top box for television that offers more advanced computing ability and connectivity than a contemporary basic television set. A Smart TVs is an

computer system of a mobile device integrated with a television set unit. A Smart TV runs a complete operating system or mobile operating system that may provide a platform for application developers. Thus, a Smart TV often allows the user to install and run more advanced applications or plugins/addons based on its specific platform.[1][11][12]

A Smart TV platform has a public

app store so end-users can install and uninstall apps. The public SDK enables third-party application developers to write applications once and see them run successfully on any device
that supports the Smart TV platform architecture it was written for, regardless of the hardware manufacturer.

Smart TVs deliver content (such as photos, movies and music) from other computers or network attached storage devices on a network using either a

social networking, and other multimedia applications.[13] Smart TV enables access to movies, shows, video games, apps and more. Some of those apps include Netflix, Hulu, Spotify, YouTube, and Amazon.[14]

History

In the early 1980s, "intelligent" television receivers were introduced in Japan. The addition of an

LSI chip with memory and a character generator to a television receiver enabled Japanese viewers to receive a mix of programming and information transmitted over spare lines of the broadcast television signal.[15] A patent was filed in 1994[16] (and extended the following year)[17]
for an "intelligent" television system, linked with data processing systems, by means of a digital or analog network. Apart from being linked to data networks, one key point is its ability to automatically download necessary software routines, according to a user's demand, and process their needs.

However, descriptions of the elements of a smart television can be found in public discourse from the beginning of the 1980s, if not earlier, with the introduction of videotex services, particularly teletext information for reception by television sets, leading commentators to consider that televisions and accessories would evolve to encompass a range of related activities. In the words of one commentator: "In the long run, this machine is likely to develop into a multi-purpose receiver, for electronic mail, dealing with the bank, calculations, remote information - and 'Not the nine o'clock news' or 'Casablanca' on video."[18]

The mass acceptance of digital television in the mid-late 2000s and early 2010s greatly improved Smart TVs. Major TV manufacturers have announced production of Smart TVs only for their middle-end to high-end TVs in 2015.[19][20][21] Smart TVs became the dominant form of television during the late 2010s. At the beginning of 2016, Nielsen reported that 29 percent of those with incomes over $75,000 a year had a Smart TV.[22]

Typical features

Smart TV devices also provide access to

natural language user interface.[30] Smart TV develops new features to satisfy consumers and companies, such as new payment processes. LG and PaymentWall
have collaborated to allow consumers to access purchased apps, movies, games, and more using a remote control, laptop, tablet, or smartphone. This is intended for an easier and more convenient way for checkout.

Platforms

Samsung's discontinued Orsay platform

Smart TV technology and software is still evolving, with both

over-the-top media services and interactive on-demand media, personalized communications, and have social networking features.[31][32][33][34]

TCL, TiVO, Toshiba, Sling Media, and Western Digital. Sony, Panasonic, Samsung, LG, and Roku TV are some platforms ranked under the best Smart TV platforms.[35]

Sales

According to a report from research group NPD In-Stat, in 2012 only about 12 million U.S. households had their Web-capable TVs connected to the Internet, although an estimated 25 million households owned a set with the built-in network capability. In-Stat predicted that by 2016, 100 million homes in North America and western Europe would be using television sets blending traditional programming with internet content.[36] By the end of 2019, the number of installed Connect TVs reached 1.26 billion worldwide.[37]

The number of households using

Hulu Plus; 43% of pay-TV subscribers also used Netflix, and 43% of adults used some streaming video on demand service at least monthly. Additionally, 19% of Netflix subscribers shared their subscription with people outside of their households. Ten percent of adults at the time showed interest in HBO Now.[38]

Use and issues

Social networking

See also: Social media and television

Some Smart TV platforms come prepackaged or can be optionally extended, with social networking technology capabilities. The addition of social networking synchronization to Smart TV and HTPC platforms may provide an interaction both with on-screen content and with other viewers than is currently available to most televisions, while simultaneously providing a much more cinematic experience of the content than is currently available with most computers.[39]

Advertising

Some Smart TV platforms also support

addressable advertising with local advertising insertion and targeted advertising,[40] and other advanced advertising features such as ad telescoping[41] using VOD and DVR, enhanced TV for consumer call-to-action, and audience measurement solutions for ad campaign effectiveness.[42][43] The marketing and trading possibilities offered by Smart TVs are sometimes summarized by the term t-commerce. Taken together, this bidirectional data flow means Smart TVs can be and are used for clandestine observation of the owners. Even in sets that are not configured off-the-shelf to do so, default security measures are often weak and will allow hackers to easily break into the TV.[44]

2019 research, "Watching You Watch: The Tracking Ecosystem of Over-the-Top TV Streaming Devices", conducted at

Princeton and University of Chicago, demonstrated that a majority of streaming devices will covertly collect and transmit personal user data, including captured screen images, to a wide network of advertising and analytics companies, raising privacy concerns.[45]

television advertising market share – in advertising on connected TV like Hulu and Roku, to be underway in 2019, with market indicators that the figure would surpass $10 billion in 2021.[46][47]

Security

There is evidence that a Smart TV is vulnerable to attacks. Some serious security bugs have been discovered, and some successful attempts to run malicious code to get unauthorized access were documented on video. There is evidence that it is possible to gain root access to the device, install malicious software, access and modify configuration information for a remote control, remotely access and modify files on TV and attached USB drives, access camera and microphone.[48]

There have also been concerns that

root access on the device.[49]

Hackers have misused Smart TV's abilities such as operating source codes for applications and its unsecured connection to the Internet. Passwords, IP address data, and credit card information can be accessed by hackers and even companies for advertisement. A company caught in the act is

CIA's software capabilities, such as the ability to compromise Smart TVs.[53]

Restriction of access

Internet websites can block Smart TV access to content at will or tailor the content that will be received by each platform.

Viacom's subsidiaries.[55]

Reliability

In 2017, high-end Samsung Smart TVs stopped working for at least seven days after a software update.[56] Application providers are rarely upgrading Smart TV apps to the latest version; for example, Netflix does not support older TV versions with new Netflix upgrades.[57]
