Social networkingedit

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 with both on-screen content and 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.

Advertisingedit

Some Smart TV platforms also support interactive advertising, addressable advertising with local advertising insertion and targeted advertising, and other advanced advertising features such as ad telescoping using VOD and DVR, enhanced TV for consumer call-to-action, and audience measurement solutions for ad campaign effectiveness. The marketing and trading possibilities offered by Smart TVs are sometimes summarized by the term t-commerce. Taken together, this bidirectional data flow means that 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.

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.

Digital marketing research firm eMarketer reported a 38 percent surge—to close to $7 billion, a 10 percent 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.

Securityedit

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..

There have also been concerns that hackers may be able to remotely turn on the microphone or webcam on a smart TV, being able to eavesdrop on private conversations. A common loop antenna may be set for a bidirectional transmission channel, capable of uploading data rather than only receiving. Since 2012, security researchers discovered a similar vulnerability present in more series of Smart Tvs, which allows hackers to get an external root access on the device.

Anticipating growing demand for an antivirus for a Smart TV, some security software companies are already working with partners in the digital TV field on the solution. It seems like there is only one antivirus for Smart TVs available: 'Neptune', a cloud-based antimalware system developed by Ocean Blue Software in partnership with Sophos. However, antivirus company Avira has joined forces with digital TV testing company Labwise to work on software to protect against potential attacks. The privacy policy for Samsung's Smart TVs has been called Orwellian (a reference to George Orwell and the dystopian world of constant surveillance he depicted in 1984), and compared to Telescreens because of eavesdropping concerns.

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 Vizio.citation needed The confidential documents, codenamed Vault 7 and dated from 2013–2016, include details on CIA's software capabilities, such as the ability to compromise Smart TVs.

Restriction of accessedit

Internet websites can block Smart TV access to content at will or tailor the content that will be received by each platform. Google TV-enabled devices were blocked by NBC, ABC, CBS, and Hulu from accessing their Web content since the launch of Google TV in October 2010. Google TV devices were also blocked from accessing any programs offered by Viacom’s subsidiaries.

Reliabilityedit

In 2017, high-end Samsung Smart TVs stopped working for at least seven days after a software update. 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.

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. A patent was filed in 1994 (and extended the following year) 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. The mass acceptance of digital television in the 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. Smart TVs became the dominant form of television by the late 2010s.

Smart TV

Image
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 provide Internet TV, online interactive media, over-the-top content (OTT) as well as on-demand streaming media, and home networking access. Smart TV should not be confused with Internet TV, IPTV, or Web 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. Web television is a term used for programs

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. Smart TVs may be thought of as an information appliance or the computer system from a mobile device integrated within a television set unit. As such, a Smart TV often allows the user to install and run more advanced applications or plugins/addons based on a specific platform. Smart TVs run a complete operating system or mobile operating system software providing a platform for application developers. Smart TV platforms or middleware have a public software development kit (SDK) and/or native development kit (NDK) for apps so that third-party developers can develop applications for it, and an app store so that the end-users can install and uninstall apps themselves. The public SDK enables third-party companies and other interactive application developers to "write&quo
