Clivia II FER858A (VEB Rafena, Radeberg, Germany), 1956
'Television' (often abbreviated to 'TV', 'T.V.'; sometimes called , 'telly' or 'the tube', 'bloob tube' or 'boob tube', or idiot box in
British English) is a widely used
telecommunication system for
broadcasting and receiving
moving pictures and
sound over a distance. The term may also be used to refer specifically to a television set,
programming or television
transmission. The word is derived from mixed
Latin and
Greek roots, meaning "far sight": Greek ''tele'' (), far, and Latin ''vision'', sight (from ''video, vis-'' to see).
Since it first became
commercially available from the late 1930s, the television set has become a common household communications device in homes and institutions, particularly in the
first world, as a source of entertainment and news. Since the 1970s,
video recordings on VCR tapes and later, digital playback systems such as
DVDs, have enabled the television to be used to view recorded movies and other programs.
A television system may be made up of multiple components, so a screen which lacks an internal
tuner to receive the broadcast signals is called a monitor rather than a television. A television may be built to receive different broadcast or video formats, such as high-definition television (
HDTV).

Technology
Elements of a television system
''
The elements of a simple
broadcast television system are:
★ An image source. This is the electrical signal representing the visual image, and may be from a
camera in the case of live images, a
video tape recorder for playback of recorded images, or a
film chain-
telecine-
flying spot scanner for transmission of motion pictures (
films).
★ A sound source. This is an electrical signal from a
microphone or from the audio output of a
video tape recorder or motion picture film scanner.
★ A
transmitter, which generates
radio signals (
radio waves) and encodes them with picture and sound information.
★ An
antenna coupled to the output of the
transmitter for
broadcasting the encoded signals.
★ An
antenna to receive the
broadcast signals.
★ A receiver (also called a
tuner), which decodes the picture and sound information from the
broadcast signals, and whose input is coupled to the antenna.
★ A display device, which turns the electrical signals into visual images.
★ An
audio amplifier and
loudspeaker, which turns electrical signals into sound waves (speech, music, and other sounds) to accompany the images.
Practical television systems include equipment for selecting different image sources, mixing images from several sources at once, insertion of pre-recorded video signals, synchronizing signals from many sources, and direct image generation by
computer for such purposes as station identification. The facility for housing such equipment, as well as providing space for stages, sets, offices, etc., is called a
television studio, and may be located many miles from the
transmitter. Communication from the studio to the
transmitter is accomplished via a dedicated cable or
radio system.
Television signals were originally transmitted exclusively via land-based transmitters. The quality of reception varied greatly, dependent in large part on the location and type of receiving antenna. This led to the proliferation of large rooftop antennas to improve reception in the 1960s, replacing set-top
dipole or "rabbit ears" antennas, which however remained popular.
Antenna rotors, set-top controlled
servo motors to which the mast of the antenna is mounted, to enable rotating the antenna such that it points to the desired transmitter, would also become popular.
In most cities today,
cable television providers deliver signals over
coaxial or
fiber-optic cables for a fee. Signals can also be delivered by
radio from
satellites in
geosynchronous orbit and received by
parabolic dish antennas, which are comparatively large for
analog signals, but much smaller for
digital. Like cable providers,
satellite television providers also require a fee, often less than cable systems. The affordability and convenience of digital satellite reception has led to the proliferation of small dish antennas outside many houses and apartments.
Digital systems may be inserted anywhere in the chain to provide better image transmission quality, reduction in transmission
bandwidth, special effects, or security of transmission from reception by non-subscribers. A home today might have the choice of receiving analog or
HDTV over the air, analog or digital cable with
HDTV from a
cable television company over
coaxial cable, or even from the phone company over
fiber optic lines. On the road, television can be received by pocket sized televisions, recorded on tape or digital media players, or played back on
wireless phones (cell or "mobile" phones) over a
high-speed or "broadband" internet connection.
Display technology
Thanks to the advances in display technology, there are now several kinds of video displays used in modern TV sets:
★ 'CRT' (
cathode-ray tube): The most common screens were direct-view CRTs for up to roughly 100 cm (40 inch) (in 4:3 ratio) and 115 cm (45 inch) (in 16:9 ratio)
diagonals. These are the least expensive, and are a refined technology that can still provide the best overall picture quality value. As they do not have a fixed
native resolution, they are capable of displaying sources with different resolutions at the best possible image quality. The
frame rate or refresh rate of a typical
NTSC format CRT TV is 29.97 Hz, and for the
PAL format, 25 Hz, both are scanned with two fields per frame in an
interlaced fashion. A typical
NTSC broadcast signal's visible portion has an equivalent resolution of about 640x480 pixels. It actually could be slightly higher than that, but the
vertical blanking interval (VBI), allows other signals to be carried along with the broadcast.
★ 'Rear projection' ('RPTV'): Most very large screen TVs (to 100 inches [254 cm] or more) use
projection technology. Three types of projection systems are used in projection TVs: CRT-based,
LCD-based, and
DLP (reflective micromirror chip) -based,
D-ILA and
LCOS-based. Projection television has been commercially available since the 1970s, but at that time could not match the image sharpness of the CRT; current models are vastly improved, and offer a cost-effective large-screen display.
★
★ A variation is a '
video projector', using similar technology, which projects onto a
screen.
A modern Philips LCD TV
★ 'Flat panel' (
LCD or
plasma): Modern advances have brought
flat panels to TV that use
active matrix LCD or
plasma display technology. Flat panel LCDs and
plasma displays are as little as 25.4 mm (1 inch) thick and can be hung on a wall like a picture or put over a
pedestal. Some models can also be used as
computer monitors.
★ 'LED' technology has become one of the choices for outdoor video and stadium uses, since the advent of bright
LEDs and driver circuits. LEDs enable scalable ultra-large
flat panel video displays that other technologies may never be able to match in performance.
Each has
its pros and cons. Flat panel LCD and plasma displays have a wide viewing angle (around 160 degrees) so they may best suited for a home theatre with a wide seating arrangement. Rear projection screens do not perform well in
daylight or well-lit rooms and so are only suited to darker viewing areas.
Terminology for televisions
Pixel
resolution is the amount of individual points known as
pixels on a given screen. Use of the word pixel is fairly new, as it only dates to the introduction of the
DVD digital display standard. Before the year 2000 ''horizontal lines of resolution'' was the standard method of measurement for analog video. For example, a VHS VCR might be described as having 250 lines of resolution as measured across a circle circumscribed in the center of the screen (approximately 440 pixels edge-to-edge).
A typical resolution of 720×480 means that the television display has 720 pixels across and 480 pixels on the vertical axis. The higher the resolution on a specified display the sharper the image. Contrast
ratio is a measurement of the range between the brightest and darkest points on the screen.
The higher the contrast ratio, the better looking picture there is in terms of richness, deepness, and
shadow detail. The
brightness of a picture measures how vibrant and impacting the colors are. Measured in
equivalent to the amount of candles required to power the
image.
On the other hand, the so-called ''brightness'' and ''contrast'' adjustment controls on televisions and monitors are traditionally used to control different aspects of the picture display.
The brightness control shifts the black point, or shadow level, primarily affecting the contrast ratio or gamma of the image, while the contrast control primarily controls the image intensity or brightness.
[1]
Transmission band
There are various bands on which televisions operate depending upon the country. The
VHF and
UHF signals in bands III to V are generally used. Lower frequencies do not have enough
bandwidth available for television. Although the
BBC initially used Band I VHF at 45 MHz, this frequency is (in the UK) no longer in use for this purpose. Band II is used for FM radio transmissions. Higher frequencies behave more like light and do not penetrate buildings or travel around obstructions well enough to be used in a conventional broadcast TV system, so they are generally only used for
MMDS and
satellite television, which uses frequencies from 2 to 12 GHz. TV systems in most countries relay the video as an AM (
amplitude-modulation) signal and the sound as a FM (
frequency-modulation) signal. An exception is
France, where the sound is AM.
Aspect ratios
'
Aspect ratio' refers to the ratio of the horizontal to vertical measurements of a television's picture. Mechanically scanned television as first demonstrated by
John Logie Baird in 1926 used a 7:3 vertical aspect ratio, oriented for the head and shoulders of a single person in close-up.
Most of the early electronic TV systems from the mid-1930s onward shared the same
aspect ratio of 4:3 which was chosen to match the
Academy Ratio used in cinema films at the time. This ratio was also square enough to be conveniently viewed on round
cathode-ray tubes (CRTs), which were all that could be produced given the
manufacturing technology of the time. (Today's CRT technology allows the manufacture of much wider tubes, and the flat-screen technologies which are becoming steadily more popular have no technical aspect ratio limitations at all.) The
BBC's television service used a more squarish
5:4 ratio from 1936 to
3 April 1950, when it too switched to a 4:3 ratio. This did not present significant problems, as most sets at the time used round tubes which were easily adjusted to the 4:3 ratio when the transmissions changed.
In the early 1950s,
movie studios moved towards
widescreen aspect ratios such as
CinemaScope in an effort to distance their product from television. Although this was initially just a
gimmick, widescreen is still the format of choice today and 4:3 aspect ratio movies are rare.
Yet the various television systems were not originally designed to be compatible with film at all. Traditional, narrow-screen movies are projected onto a television camera either so that the top of the screens line up to show facial features, or, for films with subtitles, the bottoms. What this means is that filmed newspapers or long captions filling the screen for explanation are cut off at each end. Similarly, while the frame rate of sound films is 24 per second, the screen scanning rate of the NTSC is 29.97
Hz (per second), which requires a complex scanning schedule. That of PAL and SECAM are 50 Hz, which means that films are shortened (and the sound is offkey) by scanning each frame twice for 25 per second.
The switch to
digital television systems has been used as an opportunity to change the standard television picture format from the old ratio of 4:3 (1.33:1) to an aspect ratio of 16:9 (approximately 1.78:1). This enables TV to get closer to the aspect ratio of modern widescreen
movies, which range from 1.66:1 through 1.85:1 to 2.35:1. There are two methods for transporting widescreen content, the most common of which uses what is called
anamorphic widescreen format. This format is very similar to the technique used to fit a widescreen movie frame inside a 1.33:1 35 mm film frame. The image is compressed horizontally when recorded, then expanded again when played back. The anamorphic widescreen 16:9 format was first introduced via European
PALPlus television broadcasts and then later on "widescreen"
DVDs; the
ATSC HDTV system uses straight widescreen format, no horizontal compression or expansion is used.
Recently "widescreen" has spread from television to computing where both
desktop and
laptop computers are commonly equipped with widescreen displays. There are some complaints about distortions of movie picture ratio due to some DVD playback software not taking account of aspect ratios; but this may subside as the DVD playback software matures. Furthermore, computer and laptop widescreen displays are in the 16:10 aspect ratio both physically in size and in pixel counts, and not in 16:9 of consumer televisions, leading to further complexity. This was a result of widescreen computer display engineers' assumption that people viewing 16:9 content on their computer would prefer that an area of the screen be reserved for playback controls,
subtitles or their Taskbar, as opposed to viewing content full-screen.
Aspect ratio incompatibility
The television industry's changing of
aspect ratios is not without difficulties, and can present a considerable problem.
Displaying a widescreen aspect (rectangular) image on a conventional aspect (square or 4:3) display can be shown:
★ in "
letterbox" format, with black horizontal bars at the top and bottom
★ with part of the image being cropped, usually the extreme left and right of the image being cut off (or in "
pan and scan", parts selected by an operator or a viewer)
★ with the image horizontally compressed
A conventional aspect (square or 4:3) image on a widescreen aspect (rectangular with longer horizon) display can be shown:
★ in "
pillar box" format, with black vertical bars to the left and right
★ with upper and lower portions of the image cut off (or in "tilt and scan", parts selected by an operator)
★ with the image vertically compressed
A common compromise is to shoot or create material at an aspect ratio of 14:9, and to lose some image at each side for 4:3 presentation, and some image at top and bottom for 16:9 presentation. In recent years, the cinematographic process known as
Super 35 (championed by
James Cameron) has been used to film a number of major movies such as
''Titanic'', ''
Legally Blonde'', ''
Austin Powers'', and ''
Crouching Tiger, Hidden Dragon'' (see also: ). This process results in a camera-negative which can then be used to create both wide-screen theatrical prints, and standard "
full screen" releases for television/VHS/DVD which avoid the need for either "
letterboxing" or the severe loss of information caused by conventional "
pan-and-scan" cropping.

NTSC
In North America, the basic signal standards since 1941 have been compatible enough that even the oldest monochrome televisions can still receive color broadcasts in 2007. However, the United States Congress has passed a law which requires the cessation of all conventional television broadcast signals by February 2009. If the law is not changed again, then after that date all
NTSC standard televisions, with analog-only tuners, will go dark unless fitted with digital
ATSC tuners, and the spectrum previously occupied by those analog channels will be auctioned off by the United States' Federal Communications Commission for other uses. The analog cut-off date has been changed by Congress in the past.
PAL and SECAM
PAL and
SECAM are expected not to be broadcast in Europe and Eurasia by the mid-2020s. PAL-M may have a similar decommissioning timeline.
The
European Union has recommended its members to have closed down analogue terrestrial television by 2012. Luxembourg and the Netherlands had already completed their closedowns in 2006, and Finland and Sweden will have closed down their analogue broadcasts in 2007. Meanwhile, some countries may have difficulties making the 2012 deadline.
Television add-ons
The television was the first consumer mass market for video displays. Today there are many television add-ons including
video game consoles,
VCRs,
Set-top boxes for
Cable,
Satellite and DVB-T compliant
Digital Television reception,
DVD players, or
Digital Video Recorders (including personal video recorders, PVRs). The add-on market continues to grow as new technologies are developed. Computers, the internet, and even pocket devices such as the iPod provide other ways to consume video content.
New developments
Exterior designs
In the early days of television, the cabinets were made of wood grain, however, they were phased out in the 1980s. There has been a modern comeback of the woodgrain.

Content
Programming
Getting TV programming shown to the public can happen in many different ways. After production the next step is to market and deliver the product to whatever markets are open to using it. This typically happens on two levels:
#'Original Run' or 'First Run' – a producer creates a program of one or multiple episodes and shows it on a station or network which has either paid for the production itself or to which a license has been granted by the producers to do the same.
#'
Syndication' – this is the terminology rather broadly used to describe secondary programming usages (beyond original run). It includes secondary runs in the country of first issue, but also international usage which may or may not be managed by the originating producer. In many cases other companies,
TV stations or individuals are engaged to do the syndication work, in other words to sell the product into the markets they are allowed to sell into by contract from the copyright holders, in most cases the producers.
In most countries, the first wave occurs primarily on
free-to-air (FTA) television, while the second wave happens on subscription TV and in other countries. In the U.S., however, the first wave occurs on the FTA networks and subscription services, and the second wave travels via all means of distribution.
First run programming is increasing on subscription services outside the U.S., but few domestically produced programs are syndicated on domestic FTA elsewhere. This practice is increasing however, generally on digital-only FTA channels, or with subscriber-only first run material appearing on FTA.
Unlike the U.S., repeat FTA screenings of a FTA network program almost only occur on that network. Also,
Affiliates rarely buy or produce non-network programming that isn't centred around local events.
Advertising
Since inception in the U.S. in 1940,
TV commercials have become one of the most effective, most persuasive, and most popular methods of selling products of many sorts, especially consumer goods. U.S.
advertising rates are determined primarily by
Nielsen Ratings. The time of the day and popularity of the channel determine how much a television commercial can cost. For example, the highly popular
American Idol can cost approximately $750,000 for a thirty second block of commercial time; while the same amount of time for the
World Cup and the
Super Bowl can cost several million dollars.
In recent years, the paid program or
infomercial has become common, usually in lengths of 30 minutes or one hour. Some drug companies have even created "news" items for broadcast, paying
program directors to use them.
[4]
Some TV programs also weave advertisements into their shows, a practise begun in film and known as
product placement. For example, a character could be drinking a certain kind of soda, going to a particular chain restaurant, or driving a certain make of car. (This is sometimes very subtle, where shows have vehicles provided by manufacturers for low cost, rather than
wrangling them.) Sometimes a specific brand or trade mark, or music from a certain artist or group, is used. (This excludes guest appearances by artists, who perform on the show.)
Television genres
Television
genres include a broad range of programming types that entertain, inform, and educate viewers. The most expensive entertainment genres to produce are usually drama and dramatic miniseries. However, other genres such as historical Western genres may also have high production costs.
Popular entertainment genres include action-oriented shows such as police, crime, detective dramas, horror or thriller shows. As well, there are also other variants of the drama genre, such as medical dramas and daytime Soap Operas. Sci-fi (Science fiction) shows can fall into either the drama category or the action category, depending on whether they emphasize philosophical questions or explosive space battles. Comedy is a popular genre which includes sitcoms (Situation Comedy) and animated shows for the adult demographic such as ''
South Park''.
The least expensive forms of entertainment programming are game shows, talk shows, variety shows, and reality TV. Game shows show contestants answering questions and solving puzzles to win prizes. Talk shows feature interviews with film, television and music celebrities and public figures. Variety shows feature a range of musical performers and other entertainers such as comedians and magicians introduced by a host or Master of Ceremonies. There is some crossover between some talk shows and variety shows, because leading talk shows often feature performances by bands, singers, comedians, and other performers in between the interview segments.
Reality TV shows show "regular" people (i.e., not actors) who are facing unusual challenges or experiences, ranging from arrest by police officers (''
COPS'') to weight loss (''
The Biggest Loser''). A variant version of reality shows depicts celebrities doing mundane activities such as going about their everyday life (''
The Osbournes'') or doing manual labour jobs (''
Simple Life'').
One of the television genres, the children's and youth genre is defined by the audience, rather than by the content of the programming. Children's programming includes animated programs aimed at the child demographic, documentaries for children, and music/variety shows targeted at kids. There is overlap between the children's/youth genre and other genres, such as the educational genre.
Television genres that aim to educate and inform viewers include
educational shows, DIY programs on cooking, gardening, or home renovation, history shows, performing arts programs, and documentaries. Other genres which inform viewers include news, sports, and public affairs programming.
Social aspects
Technology trends
In its infancy, television was an ephemeral medium. Fans of regular shows planned their
schedules so that they could be available to watch their shows at their time of broadcast. The term ''appointment television'' was coined by marketers to describe this kind of attachment.
The viewership's dependence on schedule lessened with the invention of programmable video recorders, such as the
Videocassette recorder and the
Digital video recorder. Consumers could watch programs on their own schedule once they were broadcast and recorded. Television service providers also offer
video on demand, a set of programs which could be watched at any time.
Both
mobile phone networks and the
Internet are capable of carrying video streams. There is already a fair amount of Internet TV available, either live or as downloadable programs, and video sharing websites have become greatly popular.
The Japanese manufacturer Scalar has developed a very small TV-system attached to the eyeglasses, called "Teleglass T3-F".
[5]
Suitability for audience
Almost since the medium's inception there have been charges that some programming is, in one way or another, inappropriate,
offensive or
indecent. Critics such as Jean Kilborne have claimed that television, as well as other mass media images, harm the self image of young girls. Other commentators such as
Sut Jhally make the case that television advertisers in the U.S. deliberately try to equate happiness with the purchasing of products, despite studies which show that happiness for most people comes from non-material realms, such as warm friendships and feelings of connection to one's community.
[6] George Gerbner has presented evidence that the frequent portrayals of crime, especially minority crime, has led to the
Mean World Syndrome, the view among frequent viewers of television that crime rates are much higher than the actual data would indicate. In addition, a lot of television has been charged with presenting propaganda, political or otherwise, and being pitched at a low intellectual level.
Alleged dangers
Paralleling television's growing primacy in family life and society, an increasingly vocal chorus of legislators,
scientists and
parents are raising objections to the uncritical acceptance of the medium. For example, the
Swedish government imposed a total ban on advertising to
children under twelve in 1991 (see
advertising). Fifty years of research on the impact of television on children's emotional and social development demonstrate that there are clear connections between watching violence on television and engaging in aggressive or violent behavior.
[7] In a recent study published in the journal Media Psychology, the research team demonstrated that the brain activation patterns of children viewing violence show that children are aroused by the violence (increased heart rates), demonstrate fear (activation of the
amygdala-the fight or flight sensor in the brain) in response to the video violence, and store the observed violence in an area of the brain (the
posterior cingulate) that is reserved for long-term memory of traumatic events.
[8]
A 2002 article in Scientific American suggested that compulsive television watching,
television addiction, was no different from any other
addiction, a finding backed up by reports of withdrawal symptoms among families forced by circumstance to cease watching.
[9] A longitudinal study in
New Zealand involving 1000 people (from childhood to 26 years of age) demonstrated that "television viewing in childhood and adolescence is associated with poor educational achievement by 12 years of age". In other words, the more the child watched television, the less likely he or she was to finish school and enroll in a
university.
[10] A study published in the
Journal of Sexuality Research and Social Policy concluded that parental television involvement was associated with greater body satisfaction among adolescent girls, less sexual experience amongst both male and female adolescents, and that parental television involvement may influence self-esteem and body image, in part by increasing parent-child closeness.
[11] Numerous studies have been done on the relationship between TV viewing and school grades.
[12]
One of the reasons people campaign against TV is because of the activities people are not doing during the time that they watch it. Many campaigners believe that using up 3.5 hours a day on TV (UK and American average) is not worthwhile. While only 3% of American minors own personal TV's, it is estimated that the daily viewing average among 12–17 yr olds exceeds 4 hours, with this figure being dramatically higher in parts of the United States.
Propaganda delivery
Audiovisual media, including television, is the second most effective means of communication available to the psychological operator. Effectiveness is based on seeing and hearing the persuasive message. These media are an excellent means of transmitting persuasive messages and eliciting a high degree of recall.
[13]
Propaganda can exist on
news,
current affairs or
talk show segments, as
advertising or public-service announce "spots" or as long-running
advertorials.
[14]
Educational advantages
Despite this research, many media scholars today dismiss such studies as flawed. For one example of this school of thought, see
David Gauntlett's article "
Ten Things Wrong With the Media 'Effects' Model." Dimitri Christakis cites studies in which those who watched "
Sesame Street" and other educational programs as preschoolers had higher grades, were reading more books, placed more value on achievement and were more creative. Similar, while those exposed to negative role models suffered, those exposed to positive models behaved better.
[15] Modern children can be exposed to much more history, news and science than previous generations when information was only available from newspapers and books.

Environmental aspects
With high
lead content in
CRTs, and the rapid diffusion of new, flat-panel display technologies, some of which (
LCDs) use lamps containing
mercury, there is growing concern about
electronic waste from discarded televisions. Related
occupational health concerns exist, as well, for disassemblers removing copper wiring and other materials from CRTs. Further environmental concerns related to television design and use relate to the devices' increasing
electrical energy requirements.
