Satellite television is a service that delivers television programming to viewers by relaying it from a communications satellite orbiting the Earth directly to the viewer's location. The signals are received via an outdoor parabolic antenna commonly referred to as a satellite dish and a low-noise block downconverter .
142-419: A satellite receiver decodes the desired television program for viewing on a television set . Receivers can be external set-top boxes , or a built-in television tuner . Satellite television provides a wide range of channels and services. It is usually the only television available in many remote geographic areas without terrestrial television or cable television service. Different receivers are required for
284-415: A Molniya orbit . Satellite television, like other communications relayed by satellite, starts with a transmitting antenna located at an uplink facility. Uplink satellite dishes are very large, as much as 9 to 12 meters (30 to 40 feet) in diameter. The increased diameter results in more accurate aiming and increased signal strength at the satellite. The uplink dish is pointed toward a specific satellite and
426-638: A TV show , is the general reference to any content produced for viewing on a television set that is traditionally broadcast via over-the-air, satellite , or cable . This includes content made by television broadcasters with in-house productions and content made for broadcasting by film production companies. It excludes breaking news , advertisements , or trailers that are typically placed between shows. Television shows are most often scheduled for broadcast well ahead of time and appear on electronic guides or other TV listings , but streaming services often make them available for viewing anytime. The content in
568-487: A low-noise amplifier (LNA) connected to the feedhorn at the focal point of the dish. The amplified signal, still at the higher microwave frequencies, had to be fed via very expensive low-loss 50-ohm impedance gas filled hardline coaxial cable with relatively complex N-connectors to an indoor receiver or, in other designs, a downconverter (a mixer and a voltage-tuned oscillator with some filter circuitry) for downconversion to an intermediate frequency. The channel selection
710-474: A Canadian show's season normally runs to a maximum of 13 episodes rather than 20 or more, although an exceptionally popular series such as Corner Gas or Murdoch Mysteries might receive 20-episode orders in later seasons. Canadian shows do not normally receive "back nine" extensions within the same season, however; even a popular series simply ends for the year when the original production order has finished airing, and an expanded order of more than 13 episodes
852-475: A DBS service, but are received in approximately 18 million homes, as well as in any home using the Sky Deutschland commercial DBS system. All German analogue satellite broadcasts ceased on 30 April 2012. The United Kingdom has approximately 160 digital channels (including the regional variations of BBC channels, ITV channels, Channel 4 and Channel 5 ) that are broadcast without encryption from
994-684: A concluding episode, which sometimes is a big series finale . On rare occasions, a series that has not attracted particularly high ratings and has been canceled can be given a reprieve if home video viewership has been particularly strong. This has happened in the cases of Family Guy in the US and Peep Show in the UK. In the United States, if the show is popular or lucrative, and a minimum number of episodes ( usually 100 ) have been made, it can go into broadcast syndication , where rights to broadcast
1136-411: A license fee to the studio for the right to air the show. This license fee does not cover the show's production costs, leading to the deficit. Although the studio does not make its money back in the original airing of the show, it retains ownership of the show. This allows the studio to make its money back and earn a profit through syndication and sales of DVDs and Blu-rays . This system places most of

A television show is also called a television program ( British English : programme ), especially if it lacks a narrative structure . In the United States and Canada , a television series is usually released in episodes that follow
1420-482: A lower profile than those aired during the main season and can also include limited series events. Reality and game shows have also been fixtures of the schedule. In Canada, the commercial networks air most US programming in tandem with the US television season, but their original Canadian shows follow a model closer to British than US television production. Due to the smaller production budgets available in Canada,
1562-468: A narrative and are usually divided into seasons . In the UK, a television series is a yearly or semiannual set of new episodes. In effect, a "series" in the United Kingdom, Ireland, and Australia is the same as a "season" in the United States and Canada. A small or one-off collection of episodes may also be called a limited series , TV special , or miniseries . A television film , or telefilm ,

#17327941244881704-576: A normal parabolic satellite antenna means it can only receive signals from a single satellite at a time. Simulsat or the Vertex-RSI TORUS, is a quasi-parabolic satellite earthstation antenna that is capable of receiving satellite transmissions from 35 or more C - and K u -band satellites simultaneously. In 1945 British science fiction writer Arthur C. Clarke proposed a worldwide communications system which would function by means of three satellites equally spaced apart in earth orbit. This
1846-454: A person or company decides to create new content for television broadcast, they develop the show's elements, consisting of the concept , the characters , the crew , and the cast. Then they often "pitch" it to the various networks in an attempt to find one interested enough to order a prototype for the first episode of the series, known as a pilot . Eric Coleman , an animation executive at Disney , told an interviewer, "One misconception
1988-411: A rooftop parabolic receiving dish (" satellite dish "), which reflects the weak signal to the dish's focal point. Mounted on brackets at the dish's focal point is a feedhorn which passes the signals through a waveguide to a device called a low-noise block converter (LNB) or low noise converter (LNC) attached to the horn. The LNB amplifies the weak signals, filters the block of frequencies in which
2130-440: A script is approved. A director is chosen to plan the episode's final look. Pre-production tasks include storyboarding; construction of sets, props, and costumes; casting guest stars; budgeting; acquiring resources like lighting, special effects, stunts, etc. Once the show is planned, it must then be scheduled: scenes are often filmed out of sequence, and guest actors or even regulars may only be available at certain times. Sometimes
2272-647: A series of Soviet geostationary satellites to carry direct-to-home television, Ekran 1, was launched on 26 October 1976. It used a 714 MHz UHF downlink frequency so that the transmissions could be received with existing UHF television technology rather than microwave technology. The satellite television industry developed in the US from the cable television industry as communication satellites were being used to distribute television programming to remote cable television headends . Home Box Office (HBO), Turner Broadcasting System (TBS), and Christian Broadcasting Network (CBN, later The Family Channel ) were among
2414-486: A single dish) pointing to different satellites. A common solution for consumers wanting to access multiple satellites is to deploy a single dish with a single LNB and to rotate the dish using an electric motor. The axis of rotation has to be set up in the north–south direction and, depending on the geographical location of the dish, have a specific vertical tilt. Set up properly the motorized dish when turned will sweep across all possible positions for satellites lined up along
2556-556: A small dish less than a meter in diameter. The first satellite TV systems were a now-obsolete type known as television receive-only . These systems received weaker analog signals transmitted in the C-band (4–8 GHz) from FSS type satellites, requiring the use of large 2–3-meter dishes. Consequently, these systems were nicknamed "big dish" systems, and were more expensive and less popular. Early systems used analog signals , but modern ones use digital signals which allow transmission of
2698-469: A small, close-knit production team. These are "pitched" in the traditional way, but since the creators handle all the writing requirements, there is a run of six or seven episodes per series once approval has been given. Many of the most popular British comedies have been made this way, including Monty Python's Flying Circus (albeit with an exclusive team of six writer-performers), Fawlty Towers , Blackadder and The Office . The production company
2840-445: A smaller dish antenna because of the higher power transmissions and greater antenna gain. TVRO systems tend to use larger rather than smaller satellite dish antennas, since it is more likely that the owner of a TVRO system would have a C-band -only setup rather than a K u band -only setup. Additional receiver boxes allow for different types of digital satellite signal reception, such as DVB/MPEG-2 and 4DTV . The narrow beam width of
2982-399: A special type of LNB. There are also LNBs available with a multi-switch already integrated. This problem becomes more complicated when several receivers use several dishes or several LNBs mounted in a single dish are aimed at different satellites. The set-top box selects the channel desired by the user by filtering that channel from the multiple channels received from the satellite, converts

#17327941244883124-418: A specific frequency range, so as to be received by one of the transponders tuned to that frequency range aboard that satellite. The transponder then converts the signals to K u band , a process known as "translation," and transmits them back to earth to be received by home satellite stations. The downlinked satellite signal, weaker after traveling the great distance (see path loss ), is collected by using
3266-512: A television show is produced by one of two production methodologies : live taped shows such as variety and news magazine shows shot on an in-house television studio stage or sporting events (all considered linear productions.) The other production model includes animation and a variety of film productions ranging from movies to series. Shows not produced on a television studio stage are usually contracted or licensed to be made by appropriate production companies. Television shows can be viewed live (in
3408-411: A tracking system to turn to follow a moving satellite. A few satellite TV systems use satellites in a Molniya orbit , a highly elliptical orbit with inclination of +/-63.4 degrees and an orbital period of about twelve hours. Satellite television, like other communications relayed by satellite, starts with a transmitting antenna located at an uplink facility. Uplink facilities transmit the signal to
3550-485: A variety of terms. In the United Kingdom and other countries, these sets of episodes are referred to as a "series". In Australia, the broadcasting may be different from North American usage. The terms series and season are both used and are the same. For example, Battlestar Galactica has an original series as well as a remake, both are considered a different series, each with their own number of individual seasons. Australian television does not follow "seasons" in
3692-454: A wider frequency range of 2–2150 MHz. The satellite receiver or set-top box demodulates and converts the signals to the desired form (outputs for television, audio, data, etc.). Often, the receiver includes the capability to selectively unscramble or decrypt the received signal to provide premium services to some subscribers; the receiver is then called an integrated receiver/decoder or IRD. Low-loss cable (e.g. RG-6 , RG-11 , etc.)
3834-480: Is a feature film created for broadcasting on television. The first television shows were experimental, sporadic broadcasts viewable only within a very short range from the broadcast tower starting in the 1930s. Televised events such as the 1936 Summer Olympics in Germany, the 1937 coronation of King George VI in the United Kingdom, and David Sarnoff's famous introduction at the 1939 New York World's Fair in
3976-578: Is a designation by the Institute of Electrical and Electronics Engineers (IEEE) for a portion of the electromagnetic spectrum in the microwave range of frequencies ranging from 4.0 to 8.0 gigahertz (GHz). However, the U.S. Federal Communications Commission C band proceeding and auction, designated 3.7–4.2 GHz as C band. The C band is used for many satellite communications transmissions, some cordless telephones , as well as some radar and weather radar systems . The C band contains
4118-412: Is applied to the next season's renewal order rather than an extension of the current season. Only the public CBC Television normally schedules Canadian-produced programming throughout the year; the commercial networks typically now avoid scheduling Canadian productions to air in the fall, as such shows commonly get lost amid the publicity onslaught of the US fall season. Instead, Canadian-produced shows on
4260-461: Is because the LNB is translating two different circular polarizations (right-hand and left-hand) and, in the case of K-band, two different frequency bands (lower and upper) to the same frequency range on the cable. Depending on which frequency and polarization a transponder is using, the satellite receiver has to switch the LNB into one of four different modes in order to receive a specific "channel". This
4402-462: Is complete, producers coordinate tasks to begin the video editing . Visual and digital video effects are added to the film; this is often outsourced to companies specializing in these areas. Often music is performed with the conductor using the film as a time reference (other musical elements may be previously recorded). An editor cuts the various pieces of film together, adds the musical score and effects, determines scene transitions, and assembles

4544-464: Is done to increase profits, as seen with shows such as The Witcher . Since at least the 2000s, new broadcast television series are often ordered (funded) for just the first 10 to 13 episodes, to gauge audience interest. If a series is popular, the network places a "back nine order" and the season is completed to the regular 20 to 26 episodes. An established series that is already popular, however, will typically receive an immediate full-season order at
4686-439: Is even more adversely affected by ice crystals in thunder clouds. On occasion, sun outage will occur when the sun lines up directly behind the geostationary satellite to which the receiving antenna is pointed. The downlink satellite signal, quite weak after traveling the great distance (see path loss ), is collected with a parabolic receiving dish, which reflects the weak signal to the dish's focal point. Mounted on brackets at
4828-474: Is handled by the receiver using the DiSEqC protocol to control the LNB mode. If several satellite receivers are to be attached to a single dish, a so-called multiswitch will have to be used in conjunction with a special type of LNB. There are also LNBs available with a multi-switch already integrated. This problem becomes more complicated when several receivers are to use several dishes (or several LNBs mounted in
4970-628: Is often separate from the broadcaster. The executive producer , often the show's creator, is in charge of running the show. They pick the crew and help cast the actors, approve and sometimes write series plots—some even write or direct major episodes—while various other producers help to ensure that the show runs smoothly. Very occasionally, the executive producer will cast themselves in the show. As with filmmaking or other electronic media production, producing of an individual episode can be divided into three parts: pre-production , principal photography , and post-production . Pre-production begins when
5112-772: Is referred to as baseband . This baseband comprises the video signal and the audio subcarrier(s). The audio subcarrier is further demodulated to provide a raw audio signal. Later signals were digitized television signals or multiplex of signals, typically QPSK . In general, digital television, including that transmitted via satellites, is based on open standards such as MPEG and DVB-S / DVB-S2 or ISDB-S . The conditional access encryption/scrambling methods include NDS , BISS , Conax , Digicipher , Irdeto, Cryptoworks , DG Crypt , Beta digital , SECA Mediaguard , Logiways , Nagravision , PowerVu , Viaccess , Videocipher , and VideoGuard . Many conditional access systems have been compromised. An event called sun outage occurs when
5254-476: Is reserved exclusively for radar altimeter installed on board aircraft and for the associated transponders on the ground. In February 2020, the U.S. Federal Communications Commission adopted rules for the C ;band at 3.7–4.2 GHz that allocated the lower 280 megahertz of the band, at 3.7–3.98 GHz, for terrestrial wireless use. Existing satellite operators will have to repack their operations into
5396-404: Is that it's very difficult to get in and pitch your show, when the truth is that development executives at networks want very much to hear ideas. They want very much to get the word out on what types of shows they're looking for." To create the pilot, the structure and team of the whole series must be put together. If audiences respond well to the pilot, the network will pick up the show to air it
5538-493: Is that the satellite's orbital period equals the rotation rate of the Earth, so the satellite appears at a fixed position in the sky. Thus the satellite dish antenna which receives the signal can be aimed permanently at the location of the satellite and does not have to track a moving satellite. A few systems instead use a highly elliptical orbit with inclination of +/−63.4 degrees and an orbital period of about twelve hours, known as
5680-419: Is transmitting at and on what polarisation it is using, the satellite receiver has to switch the LNB into one of four different modes in order to receive a specific desired program on a specific transponder. The receiver uses the DiSEqC protocol to control the LNB mode, which handles this. If several satellite receivers are to be attached to a single dish a so-called multiswitch must be used in conjunction with
5822-465: Is used to connect the receiver to the LNBF or LNB. RG-59 is not recommended for this application as it is not technically designed to carry frequencies above 950 MHz, but may work in some circumstances, depending on the quality of the coaxial wire, signal levels, cable length, etc. A practical problem relating to home satellite reception is that an LNB can basically only handle a single receiver.

6248-520: The BBC . Half-hour programs are around 22 minutes on commercial channels and around 28 minutes on the BBC. The longer duration on the BBC is due to the lack of advertising breaks. In France, most television shows (whether dramas, game shows or documentaries) have a duration of 52 minutes. This is the same on nearly all French networks (TF1, France 2, France 5, M6, Canal+, etc.). C band (IEEE) The C band
6390-438: The C-band (4–8 GHz), K u -band (12–18 GHz), or both. The leg of the signal path from the satellite to the receiving Earth station is called the downlink. A typical satellite has up to 32 K u -band or 24 C-band transponders, or more for K u / C hybrid satellites. Typical transponders each have a bandwidth between 27 and 50 MHz. Each geostationary C-band satellite needs to be spaced 2° longitude from
6532-478: The C-band frequencies and the dishes required were large; typically over 3 meters (10 ft) in diameter. Consequently, TVRO is often referred to as "big dish" or "Big Ugly Dish" (BUD) satellite television. TVRO systems were designed to receive analog and digital satellite feeds of both television or audio from both C-band and K u -band transponders on FSS -type satellites. The higher frequency K u -band systems tend to resemble DBS systems and can use
6674-588: The Gorizont communication satellites later that same year. These satellites used geostationary orbits . They were equipped with powerful on-board transponders, so the size of receiving parabolic antennas of downlink stations was reduced to 4 and 2.5 metres. On October 18, 1979, the Federal Communications Commission (FCC) began allowing people to have home satellite earth stations without a federal government license. The front cover of

The dish will then be capable of receiving any geostationary satellite that is visible at the specific location, i.e. that is above the horizon. The DiSEqC protocol has been extended to encompass commands for steering dish rotors. There are five major components in a satellite system: the programming source, the broadcast center, the satellite,
7100-465: The intermediate frequency ranges of 950–2150 MHz to carry the signal from the LNBF at the dish down to the receiver. This allows for the transmission of UHF signals along the same span of coaxial wire at the same time. In some applications ( DirecTV AU9-S and AT-9), ranges of the lower B-band and 2250–3000 MHz, are used. Newer LNBFs in use by DirecTV, called SWM (Single Wire Multiswitch), are used to implement single cable distribution and use
7242-468: The satellite dish , and the receiver . "Direct broadcast" satellites used for transmission of satellite television signals are generally in geostationary orbit 37,000 km (23,000 mi) above the earth's equator . The reason for using this orbit is that the satellite circles the Earth at the same rate as the Earth rotates, so the satellite appears at a fixed point in the sky. Thus satellite dishes can be aimed permanently at that point, and do not need

In November 2019, the FCC announced that an auction was planned, which took place in December 2020. Cable operators wanted to be compensated for
10508-520: The dish's focal point is a device called a feedhorn or collector. The feedhorn is a section of waveguide with a flared front-end that gathers the signals at or near the focal point and conducts them to a probe or pickup connected to a low-noise block downconverter (LNB). The LNB amplifies the signals and downconverts them to a lower block of intermediate frequencies (IF), usually in the L-band . The original C-band satellite television systems used
10650-538: The dishes got smaller. Originally, all channels were broadcast in the clear (ITC) because the equipment necessary to receive the programming was too expensive for consumers. With the growing number of TVRO systems, the program providers and broadcasters had to scramble their signal and develop subscription systems. In October 1984, the U.S. Congress passed the Cable Communications Policy Act of 1984 , which gave those using TVRO systems
10792-688: The early days of satellite television reception to differentiate it from commercial satellite television uplink and downlink operations (transmit and receive). This was the primary method of satellite television transmissions before the satellite television industry shifted, with the launch of higher powered DBS satellites in the early 1990s which transmitted their signals on the K u band frequencies. Satellite television channels at that time were intended to be used by cable television networks rather than received by home viewers. Early satellite television receiver systems were largely constructed by hobbyists and engineers. These early TVRO systems operated mainly on
10934-452: The episode. Director, actors, and crew gather at a television studio or on location for filming or videoing a scene. A scene is further divided into shots, which should be planned during pre-production. Depending on scheduling, a scene may be shot in non-sequential order of the story. Conversations may be filmed twice from different camera angles , often using stand-ins, so one actor might perform all their lines in one set of shots, and then
11076-402: The era and subject covered, these trucks were normally crewed by up to 15 skilled operators and production personnel. In the UK for most of the 20th century, the BBC was the preeminent provider of outside broadcast coverage. BBC crews worked on almost every major event, including Royal weddings and funerals, major political and sporting events, and even drama programs. Once principal photography
11218-554: The financial risk on the studios; however, a hit show in the syndication and home video markets can more than make up for the misses. Although deficit financing places minimal financial risk on the networks, they lose out on the future profits of big hits since they are only licensing the shows. Costs are recouped mainly by advertising revenues for broadcast networks and some cable channels, while other cable channels depend on subscriptions. In general, advertisers, and consequently networks that depend on advertising, are more interested in
11360-434: The first completely all-color network season. Television shows are more varied than most other forms of media due to the wide variety of formats and genres that can be presented. A show may be fictional (as in comedies and dramas ), or non-fictional (as in documentary , news , and reality television ). It may be topical (as in the case of a local newscast and some made-for-television films), or historical (as in
11502-580: The first satellite in history. The first public satellite television signals from Europe to North America were relayed via the Telstar satellite over the Atlantic ocean on 23 July 1962, although a test broadcast had taken place almost two weeks earlier on 11 July. The signals were received and broadcast in North American and European countries and watched by over 100 million. Launched in 1962,
11644-536: The first to use satellite television to deliver programming. Taylor Howard of San Andreas , California , became the first person to receive C-band satellite signals with his home-built system in 1976. In the US, PBS , a non-profit public broadcasting service, began to distribute its television programming by satellite in 1978. In 1979, Soviet engineers developed the Moskva (or Moscow ) system of broadcasting and delivering of TV signals via satellites. They launched
11786-487: The indoor receiver to the satellite television dish and LNB, and that the technology for handling the signal at L-band and UHF was far cheaper than that for handling the signal at C-band frequencies. The shift to cheaper technology from the hardline and N-connectors of the early C-band systems to the cheaper and simpler 75-ohm cable and F-connectors allowed the early satellite television receivers to use, what were in reality, modified UHF television tuners which selected
11928-477: The internet through a wireless router in home and small office networks, and access points in hotels, libraries, and coffee shops. The communications C band was the first frequency band that was allocated for commercial telecommunications via satellites. The same frequencies were already in use for terrestrial microwave radio relay chains. Nearly all C-band communication satellites use the band of frequencies from 3.7 to 4.2 GHz for their downlinks , and
12070-452: The last half of the episodes are sometimes referred to with the letter B as in "The last nine episodes (of The Sopranos ) will be part of what is being called either 'Season 6, Part 2' or 'Season 6B ' ", or " Futurama is splitting its seasons similar to how South Park does, doing half a season at a time, so this is season 6B for them." Since the 1990s, these shorter seasons also have been referred to as "split" or "half" seasons, which
12212-650: The later series Babylon 5 further exemplifies such structure in that it had a predetermined story running over its intended five-season run. In 2012, it was reported that television was growing into a larger component of major media companies' revenues than film. Some also noted the increase in quality of some television programs. In 2012, Academy Award-winning film director Steven Soderbergh , commenting on ambiguity and complexity of character and narrative, stated: "I think those qualities are now being seen on television, and that people who want to see stories that have those kinds of qualities are watching television." When
12354-461: The loss of 200 MHz, which would not include a guard band of 20 MHz to prevent interference. By late 2019, the commercial alliance had weakened. Eutelsat formally pulled out of the consortium in September 2019 over internal disagreements. By February 2020, it became even less of a factor in C-band spectrum reallocation as Intelsat pulled out of the alliance and communicated to the FCC that
12496-474: The main characters and premise changed little. If some change happened to the characters' lives during the episode , it was usually undone by the end. Due to this, the episodes could be broadcast in any order. Since the 1980s, many series feature progressive change in the plot, the characters, or both. For instance, Hill Street Blues and St. Elsewhere were two of the first US prime time drama television series to have this kind of dramatic structure, while
12638-470: The majority being ethnic or religious in nature). Other FTA satellites include AMC-4 , AMC-6 , Galaxy 18 , and Satmex 5. A company called GloryStar promotes FTA religious broadcasters on Galaxy 19 . Satellite TV has seen a decline in consumers since the 2010s due to the cord-cutting trend where people are shifting towards internet-based streaming television and free over-the-air television . The term television receive-only , or TVRO, arose during
12780-416: The market. Some countries operate satellite television services which can be received for free, without paying a subscription fee. This is called free-to-air satellite television. Germany is likely the leader in free-to-air with approximately 250 digital channels (including 83 HDTV channels and various regional channels) broadcast from the Astra 19.2°E satellite constellation. These are not marketed as
12922-645: The medium was a stable, modern form of entertainment that could attract advertisers . The first national live television broadcast in the US took place on September 4, 1951, when President Harry Truman 's speech at the Japanese Peace Treaty Conference in San Francisco was transmitted over AT&T 's transcontinental cable and microwave radio relay system to broadcast stations in local markets. The first national color broadcast (the 1954 Tournament of Roses Parade ) in
13064-421: The modern television standard high-definition television , due to the significantly improved spectral efficiency of digital broadcasting. As of 2022, Star One D2 from Brazil is the only remaining satellite broadcasting in analog signals. The satellites used for broadcasting television are usually in a geostationary orbit 36,000 km (22,000 mi) above the earth's equator . The advantage of this orbit
13206-417: The networks; it could originate from an independent production company (sometimes a product of both). For instance, the BBC 's long-running soap opera EastEnders is wholly a BBC production, whereas its popular drama Life on Mars was developed by Kudos in association with the broadcaster. There are still a significant number of programs (usually sitcoms ) that are built by just one or two writers and
13348-421: The next quarter to induce consumers to renew at least one more quarter. A standard television season in the United States runs predominantly during autumn . During the summer months of June through roughly mid-September, network schedules typically feature reruns of their flagship programs, first-run series with lower rating expectations, and other specials. First-run scripted series are typically shorter and of
13490-432: The next satellite to avoid interference; for K u the spacing can be 1°. This means that there is an upper limit of 360/2 = 180 geostationary C-band satellites or 360/1 = 360 geostationary K u -band satellites. C-band transmission is susceptible to terrestrial interference while K u -band transmission is affected by rain (as water is an excellent absorber of microwaves at this particular frequency). The latter
13632-445: The next season. Sometimes they save it for mid-season or request rewrites and additional review. Other times, they pass entirely, forcing the show's creator to "shop it around" to other networks. Many shows never make it past the pilot stage. The method of "team writing" is employed on some longer dramatic series (usually running up to a maximum of around 13 episodes). The idea for such a program may be generated "in-house" by one of
13774-503: The number of channels available to viewers (sometimes at premium rates) in a much more competitive environment. In the United States, the average broadcast network drama costs $ 3 million an episode to produce, while cable dramas cost $ 2 million on average. The pilot episode may be more expensive than a regular episode. In 2004, Lost 's two-hour pilot cost $ 10 to $ 14 million, in 2008, Fringe 's two-hour pilot cost $ 10 million, and in 2010, Boardwalk Empire
13916-427: The number of episodes would decrease. Australian situation comedy series' seasons are approximately 13 episodes long and premiere any time between February and November. British shows have tended toward shorter series in recent years. For example, the first series of long-running science fiction show Doctor Who in 1963 featured forty-two 25‑minute episodes, and continued with a similar number each year until it
14058-533: The number of viewers within the 18–49 age range than in the total number of viewers. Advertisers are willing to pay more to advertise on shows successful with young adults because they watch less television and are harder to reach. According to Advertising Age , during the 2007–08 season, Grey's Anatomy was able to charge $ 419,000 per commercial, compared to only $ 248,000 for a commercial during CSI , despite CSI having almost five million more viewers on average. Due to its strength with younger viewers, Friends
14200-533: The other side of the conversation is filmed from the opposite perspective. To complete a production on time, a second unit may be filming a different scene on another set or location at the same time, using a different set of actors, an assistant director, and a second unit crew. A director of photography supervises the lighting of each shot to ensure consistency. Live events are usually covered by Outside Broadcast crews using mobile television studios, known as scanners or OB trucks. Although varying greatly depending on
14342-454: The outset of the season. A midseason replacement is a less-expensive short-run show of generally 10 to 13 episodes designed to take the place of an original series that failed to garner an audience and has not been picked up. A "series finale" is the last show of the series before the show is no longer produced. (In the UK, it means the end of a season, what is known in the United States as a " season finale".) Streaming services time finales to
14484-552: The pairs of transponders act as guard bands for the likely case of imperfections in the microwave electronics . One use of the C band is for satellite communication, whether for full-time satellite television networks or raw satellite feeds, although subscription programming also exists. This use contrasts with direct-broadcast satellite , which is a completely closed system used to deliver subscription programming to small satellite dishes that are connected with proprietary receiving equipment. The satellite communications portion of
14626-420: The principal photography of different episodes must be done at the same time, complicating the schedule (a guest star might shoot scenes from two episodes on the same afternoon). Complex scenes are translated from storyboard to animatics to further clarify the action. Scripts are adjusted to meet altering requirements. Some shows have a small stable of directors, but also usually rely on outside directors. Given
14768-409: The program are then resold for cash or put into a barter exchange (offered to an outlet for free in exchange for airing additional commercials elsewhere in the station's broadcast day). The terminology used to define a set of episodes produced by a television series varies from country to country. In North American television, a series is a connected set of television program episodes that run under
14910-474: The quality of the coaxial wire. The shift to more affordable technology from the 50 ohm impedance cable and N-connectors of the early C-band systems to the cheaper 75 ohm technology and F-connectors allowed the early satellite television receivers to use, what were in reality, modified UHF television tuners which selected the satellite television channel for down conversion to another lower intermediate frequency centered on 70 MHz where it
15052-446: The ranges 5.830 to 5.850 GHz for down-links and 5.650 to 5.670 GHz for up-links. This is known as the 5-centimeter band by amateurs and the C band by AMSAT . Particle accelerators may be powered by C-band RF sources. The frequencies are then standardized at 5.996 GHz (Europe) or 5.712 GHz (US), which is the second harmonic of S band . Several tokamak fusion reactors use high-power C-band RF sources to sustain
15194-541: The region of the world] are used for Wi-Fi wireless computer networks in the 5 GHz spectrum . The C-Band Alliance was an industry consortium of four large communications satellite operators in 2018–2020. In response to a Notice of Proposed Rulemaking of July 2018 from the US Federal Communications Commission (FCC) to make the 3.7 to 4.2 GHz spectrum available for next-generation terrestrial fixed and mobile broadband services,
15336-491: The residence using cheap coaxial cable . To transport the signal into the house at its original K u band microwave frequency would require an expensive waveguide , a metal pipe to carry the radio waves. The cable connecting the receiver to the LNB are of the low loss type RG-6 , quad shield RG-6, or RG-11. RG-59 is not recommended for this application as it is not technically designed to carry frequencies above 950 MHz, but will work in many circumstances, depending on
15478-462: The right to receive signals for free unless they were scrambled, and required those who did scramble to make their signals available for a reasonable fee. Since cable channels could prevent reception by big dishes, other companies had an incentive to offer competition. In January 1986, HBO began using the now-obsolete VideoCipher II system to encrypt their channels . Other channels used less secure television encryption systems. The scrambling of HBO
15620-492: The same number of episodes per year as a drama. This is a reduction from the 1950s, in which many US shows (e.g. Gunsmoke ) had between 29 and 39 episodes per season. Actual storytelling time within a commercial television hour has also gradually reduced over the years, from 50 minutes out of every 60 to the current 44 (and even less on some networks), beginning in the early 21st century. The usage of "season" and "series" differ for DVD and Blu-ray releases in both Australia and
15762-413: The same title, possibly spanning many seasons. During the 1950s, it was common for television seasons to consist of more than 30 episodes—however, the average length has been declining since. Until the 1980s, most new programs for the US broadcast networks debuted in the "fall season", which ran from September through March and nominally contained 24 to 26 episodes. These episodes were rebroadcast during
15904-431: The satellite over a narrow beam of microwaves , typically in the C-band frequency range due to its resistance to rain fade . Uplink satellite dishes are very large, often as much as 9 to 12 metres (30 to 40 feet) in diameter to achieve accurate aiming and increased signal strength at the satellite, to improve reliability. The uplink dish is pointed toward a specific satellite and the uplinked signals are transmitted within
16046-417: The satellite television channel for down conversion to a lower intermediate frequency centered on 70 MHz, where it was demodulated. This shift allowed the satellite television DTH industry to change from being a largely hobbyist one where only small numbers of systems costing thousands of US dollars were built, to a far more commercial one of mass production. In the United States, service providers use
16188-403: The satellite television signals are transmitted, and converts the block of frequencies to a lower frequency range in the L-band range. The signal is then passed through a coaxial cable into the residence to the satellite television receiver, a set-top box next to the television. The reason for using the LNB to do the frequency translation at the dish is so that the signal can be carried into
16330-714: The satellite's transponders drowns out reception. Direct-to-home (DTH) can either refer to the communications satellites themselves that deliver service or the actual television service. Most satellite television customers in developed television markets get their programming through a direct broadcast satellite (DBS) provider. Signals are transmitted using K u band (12 to 18 GHz) and are completely digital which means it has high picture and stereo sound quality. Programming for satellite television channels comes from multiple sources and may include live studio feeds. The broadcast center assembles and packages programming into channels for transmission and, where necessary, encrypts
16472-467: The schedule. In recent years, a new season would begin in early February, and the season finale would broadcast in early December. Since Home and Away ' s inception, it normally receives 230 episodes per season. Some seasons have seen between 205 and 235 episodes commissioned. During the Olympics , Home and Away would often go on hiatus, which was referred to as an "Olympic cliffhanger". Therefore,
16614-408: The signal to a lower intermediate frequency , decrypts the encrypted signal, demodulates the radio signal and sends the resulting video signal to the television through a cable. To decrypt the signal the receiver box must be "activated" by the satellite company. If the customer fails to pay their monthly bill the box is "deactivated" by a signal from the company, and the system will not work until
16756-534: The specified broadcast programming time slot. If the Nielsen ratings are good, the show is kept alive as long as possible. If not, the show is usually canceled . The show's creators are then left to shop around for remaining episodes, and the possibility of future episodes, on other networks. On especially successful series, the producers sometimes call a halt to a series on their own like Seinfeld , The Cosby Show , Corner Gas , and M*A*S*H and end it with
16898-514: The spring (or summer) season, from April through August. Because of cable television and the Nielsen sweeps , the "fall" season now normally extends to May. Thus, a "full season" on a broadcast network now usually runs from September through May for at least 22 episodes. A full season is sometimes split into two separate units with a hiatus around the end of the calendar year, such as the first season of Jericho on CBS. When this split occurs,
17040-417: The sun lines up directly behind the satellite in the field of view of the receiving satellite dish. This happens for about a 10-minute period daily around midday, twice every year for a two-week period in the spring and fall around the equinox . During this period, the sun is within the main lobe of the dish's reception pattern, so the strong microwave noise emitted by the sun on the same frequencies used by
17182-512: The third region includes all of Asia outside of Russia, plus Australia and New Zealand . This latter region is the most populous one, since it includes China , India , Pakistan , Japan , and Southeast Asia . The Radio Regulations of the International Telecommunication Union allow amateur radio operations in the frequency range 5.650 to 5.925 GHz, and amateur satellite operations are allowed in
17324-418: The time constraints of broadcasting, a single show might have two or three episodes in pre-production, one or two episodes in principal photography, and a few more in various stages of post-production. The task of directing is complex enough that a single director can usually not work on more than one episode or show at a time, hence the need for multiple directors. Principal photography is the actual filming of
17466-446: The toroidal plasma current. Common frequencies include 3.7 GHz ( Joint European Torus , WEST (formerly Tore Supra) ), 4.6 GHz (Alcator C, Alcator C-Mod , EAST , DIII-D ), 5 GHz ( KSTAR , ITER ) and 8 GHz ( Frascati Tokamak Upgrade ). The band 4.2–4.4 GHz is currently allocated to the aeronautical radionavigation service (ARNS) on a primary worldwide basis. RR No. 5.438 notes specifically that this band
17608-477: The two types. Some transmissions and channels are unencrypted and therefore free-to-air , while many other channels are transmitted with encryption. Free-to-view channels are encrypted but not charged-for, while pay television requires the viewer to subscribe and pay a monthly fee to receive the programming. Modern systems signals are relayed from a communications satellite on the X band (8–12 GHz) or K u band (12–18 GHz) frequencies requiring only
17750-417: The underlying reception technology is similar, the pay television technology is proprietary, often consisting of a conditional-access module and smart card . This measure assures satellite television providers that only authorized, paying subscribers have access to pay television content but at the same time can allow free-to-air channels to be viewed even by the people with standard equipment available in
17892-408: The uplinked signals are transmitted within a specific frequency range, so as to be received by one of the transponders tuned to that frequency range aboard that satellite. The transponder re-transmits the signals back to Earth at a different frequency (a process known as translation, used to avoid interference with the uplink signal), typically in the 10.7-12.7 GHz band, but some still transmit in
18034-402: The upper 200 megahertz of the band, from 4.0 to 4.2 GHz, and there is a 20-megahertz guard band at 3.98–4.0 GHz. Licenses to use the 3.7–3.98 GHz band were auctioned in December 2020. Verizon, AT&T and T-Mobile are main winners of the auction . Verizon, AT&T, and T-Mobile spent approximately $ 45 billion, $ 23 billion, and $ 9 billion respectively during
18176-466: The use of gallium arsenide FET technology enabled the use of smaller dishes. Five hundred thousand systems, some costing as little as $ 2000, were sold in the US in 1984. Dishes pointing to one satellite were even cheaper. People in areas without local broadcast stations or cable television service could obtain good-quality reception with no monthly fees. The large dishes were a subject of much consternation, as many people considered them eyesores , and in
18318-502: The way that US television does; for example, there is no " fall season" or "fall schedule". For many years, popular night-time dramas in Australia would run for much of the year, and would only go into recess during the summer period (December to February, as Australia is in the Southern Hemisphere), when ratings are not taken. Therefore, popular dramas would usually run from February through November each year. This schedule
18460-641: Was Canada 's geostationary Anik 1 , which was launched on 9 November 1972. ATS-6 , the world's first experimental educational and direct broadcast satellite (DBS), was launched on 30 May 1974. It transmitted at 860 MHz using wideband FM modulation and had two sound channels. The transmissions were focused on the Indian subcontinent but experimenters were able to receive the signal in Western Europe using home constructed equipment that drew on UHF television design techniques already in use. The first in
18602-404: Was $ 18 million for the first episode. In 2011, Game of Thrones was $ 5 to $ 10 million, Pan Am cost an estimated $ 10 million, while Terra Nova 's two-hour pilot was between $ 10 and $ 20 million. Many scripted network television shows in the United States are financed through deficit financing: a studio finances the production cost of a show and a network pays
18744-495: Was able to charge almost three times as much for a commercial as Murder, She Wrote , even though the two series had similar total viewer numbers at that time. Glee and The Office drew fewer total viewers than NCIS during the 2009–10 season, but earned an average of $ 272,694 and $ 213,617 respectively, compared to $ 150,708 for NCIS. After production, the show is handed over to the television network , which sends it out to its affiliate stations , which broadcast it in
18886-546: Was cancelled. The revival of Doctor Who from 2005 has comprised thirteen 45‑minute installments. There are some series in the UK that have a larger number of episodes, for example Waterloo Road started with 8 to 12 episodes, but from series three onward it increased to twenty episodes and series seven will contain 30 episodes. Recently, US non-cable networks have also begun to experiment with shorter series for some programs, particularly reality shows, such as Survivor . They often air two series per year, resulting in roughly
19028-470: Was controlled typically by a voltage tuned oscillator with the tuning voltage being fed via a separate cable to the headend, but this design evolved. Designs for microstrip -based converters for amateur radio frequencies were adapted for the 4 GHz C-band . Central to these designs was concept of block downconversion of a range of frequencies to a lower, more easily handled IF. The advantages of using an LNB are that cheaper cable can be used to connect
19170-410: Was demodulated. An LNB can only handle a single receiver. This is due to the fact that the LNB is mapping two different circular polarisations – right hand and left hand – and in the case of the K u -band two different reception bands – lower and upper – to one and the same frequency band on the cable, and is a practical problem for home satellite reception. Depending on which frequency a transponder
19312-427: Was established in 1980. Early satellite television systems were not very popular due to their expense and large dish size. The satellite television dishes of the systems in the late 1970s and early 1980s were 10 to 16 feet (3.0 to 4.9 m) in diameter, made of fibreglass or solid aluminum or steel , and in the United States cost more than $ 5,000, sometimes as much as $ 10,000. Programming sent from ground stations
19454-528: Was launched into geosynchronous orbit on April 6, 1965. The first national network of television satellites, called Orbita , was created by the Soviet Union in October 1967, and was based on the principle of using the highly elliptical Molniya satellite for rebroadcasting and delivering of television signals to ground downlink stations. The first domestic satellite to carry television transmissions
19596-443: Was met with much protest from owners of big-dish systems, most of which had no other option at the time for receiving such channels, claiming that clear signals from cable channels would be difficult to receive. Eventually HBO allowed dish owners to subscribe directly to their service for $ 12.95 per month, a price equal to or higher than what cable subscribers were paying, and required a descrambler to be purchased for $ 395. This led to
19738-532: Was published in the October 1945 issue of the Wireless World magazine and won him the Franklin Institute 's Stuart Ballantine Medal in 1963. The first satellite relayed communication was achieved early on in the space age, after the first relay test was conducted by Pioneer 1 and the first radio broadcast by SCORE at the end of 1958, after at the beginning of the year Sputnik I became
19880-399: Was reduced to twenty-five for 1970 to accommodate changes in production and significantly reducing the actors' workload) and continued to 1984. For 1985 fewer but longer episodes were shown, but even after a return to shorter episodes in 1986, lack of support within the BBC meant fewer episodes were commissioned leading to only fourteen 25‑minute episodes up to those in 1989 after which it
20022-588: Was relayed from eighteen satellites in geostationary orbit located 22,300 miles (35,900 km) above the Earth. By 1980, satellite television was well established in the US and Europe. On 26 April 1982, the first satellite channel in the UK, Satellite Television Ltd. (later Sky One ), was launched. Its signals were transmitted from the ESA 's Orbital Test Satellites . Between 1981 and 1985, TVRO systems' sales rates increased as prices fell. Advances in receiver technology and
20164-459: Was used in the 1970s for popular dramas, including Number 96 . Many drama series, such as McLeod's Daughters , have received between 22 and 32 episodes per season. Typically, soap operas , which have always run in season format in Australia, such as Home and Away , would usually begin a new season in late January, while the season finale would air in late November, as the show is off air for two months, or sometimes longer, depending on
