CinemaScope is an anamorphic lens series used, from 1953 to 1967, and less often later, for shooting widescreen films that, crucially, could be screened in theatres using existing equipment, albeit with a lens adapter.
148-409: The Burning Hills is a 1956 American CinemaScope Western directed by Stuart Heisler and starring Tab Hunter and Natalie Wood , based on a 1956 novel by Louis L'Amour . When Trace Jordan's brother is murdered and several of their horses stolen, Trace sees by the tracks that three men are involved. One man wears Mexican spurs, one walks with a limp, and one smokes cheroots . Upon arriving in
296-458: A patent interference suit against Farnsworth. The U.S. Patent Office examiner disagreed in a 1935 decision, finding priority of invention for Farnsworth against Zworykin. Farnsworth claimed that Zworykin's 1923 system could not produce an electrical image of the type to challenge his patent. Zworykin received a patent in 1928 for a color transmission version of his 1923 patent application. He also divided his original application in 1931. Zworykin
444-473: A resolution that is substantially higher. HDTV may be transmitted in different formats: 1080p , 1080i and 720p . Since 2010, with the invention of smart television , Internet television has increased the availability of television programs and movies via the Internet through streaming video services such as Netflix, Amazon Prime Video , iPlayer and Hulu . In 2013, 79% of the world's households owned
592-600: A transistor -based UHF tuner . The first fully transistorized color television in the United States was the Quasar television introduced in 1967. These developments made watching color television a more flexible and convenient proposition. In 1972, sales of color sets finally surpassed sales of black-and-white sets. Color broadcasting in Europe was not standardized on the PAL format until
740-467: A tuner for receiving and decoding broadcast signals. A visual display device that lacks a tuner is correctly called a video monitor rather than a television. The television broadcasts are mainly a simplex broadcast meaning that the transmitter cannot receive and the receiver cannot transmit. The word television comes from Ancient Greek τῆλε (tele) 'far' and Latin visio 'sight'. The first documented usage of
888-477: A 1925 demonstration, the image was dim, had low contrast and poor definition, and was stationary. Zworykin's imaging tube never got beyond the laboratory stage. However, RCA, which acquired the Westinghouse patent, asserted that the patent for Farnsworth's 1927 image dissector was written so broadly that it would exclude any other electronic imaging device. Thus, based on Zworykin's 1923 patent application, RCA filed
1036-403: A 2-inch-wide by 2.5-inch-high screen (5 by 6 cm). The large receiver had a screen 24 inches wide by 30 inches high (60 by 75 cm). Both sets could reproduce reasonably accurate, monochromatic, moving images. Along with the pictures, the sets received synchronized sound. The system transmitted images over two paths: first, a copper wire link from Washington to New York City, then
1184-402: A TV system with a 40-line resolution that employed a CRT display. This was the first working example of a fully electronic television receiver and Takayanagi's team later made improvements to this system parallel to other television developments. Takayanagi did not apply for a patent. In the 1930s, Allen B. DuMont made the first CRTs to last 1,000 hours of use, one of the factors that led to
1332-665: A camera tube, using the CRT instead as a flying-spot scanner to scan slides and film. Ardenne achieved his first transmission of television pictures on 24 December 1933, followed by test runs for a public television service in 1934. The world's first electronically scanned television service then started in Berlin in 1935, the Fernsehsender Paul Nipkow , culminating in the live broadcast of the 1936 Summer Olympic Games from Berlin to public places all over Germany. Philo Farnsworth gave
1480-609: A color television combining a traditional black-and-white display with a rotating colored disk. This device was very "deep" but was later improved with a mirror folding the light path into an entirely practical device resembling a large conventional console. However, Baird was unhappy with the design, and, as early as 1944, had commented to a British government committee that a fully electronic device would be better. In 1939, Hungarian engineer Peter Carl Goldmark introduced an electro-mechanical system while at CBS , which contained an Iconoscope sensor. The CBS field-sequential color system
1628-406: A combination of both characteristics. CinemaScope was developed to use a separate film for sound (see Audio below), thus enabling the full silent 1.33:1 aperture to be available for the picture, with a 2:1 anamorphic squeeze applied that would allow an aspect ratio of 2.66:1. When, however, developers found that magnetic stripes could be added to the film to produce a composite picture/sound print,

#17331365572971776-409: A communal viewing experience to a solitary viewing experience. By 1960, Sony had sold over 4 million portable television sets worldwide. The basic idea of using three monochrome images to produce a color image had been experimented with almost as soon as black-and-white televisions had first been built. Although he gave no practical details, among the earliest published proposals for television
1924-463: A different camera system (such as Mitchell BNCs at TCF-TV studios for RegalScope rather than Fox Studio Cameras at Fox Hills studios for CinemaScope). Fox officials were keen that the sound of their new widescreen film format should be as impressive as the picture, and that meant it should include true stereophonic sound . Previously, stereo sound in the commercial cinema had always employed separate sound films; Walt Disney's 1940 release Fantasia ,
2072-786: A fellow of the Royal Society (UK), published a letter in the scientific journal Nature in which he described how "distant electric vision" could be achieved by using a cathode-ray tube, or Braun tube, as both a transmitting and receiving device, he expanded on his vision in a speech given in London in 1911 and reported in The Times and the Journal of the Röntgen Society. In a letter to Nature published in October 1926, Campbell-Swinton also announced
2220-723: A financial interest in the process from the Mike Todd estate. Subsequent to the abandonment of CinemaScope 55, Century, which had made the 55/35mm dual-gauge projector for Fox (50 sets were delivered), redesigned this projector head into the present day 70/35mm Model JJ, and Ampex, which had made the 55/35mm dual gauge penthouse magnetic sound reproducer head specifically for CinemaScope 55, abandoned this product (but six-channel Ampex theater systems persisted, these being re-purposed from 55/35mm to 70mm Todd-AO/35mm CinemaScope). Although commercial 55 mm prints were not made, some 55 mm prints were produced. Samples of these prints reside in
2368-461: A fully exposed 1.37:1 Academy ratio -area is cropped in the projector to a wide-screen aspect ratio by the use of an aperture plate, also known as a soft matte . Most films shot today use this technique, cropping the top and bottom of a 1.37:1 image to produce one at a ratio of 1.85:1. Aware of Fox's upcoming CinemaScope productions, Paramount introduced this technique in March's release of Shane with
2516-437: A half-width optical soundtrack, while keeping the magnetic tracks for those theaters that were able to present their films with stereophonic sound. These so-called "mag-optical" prints provided a somewhat sub-standard optical sound and were also expensive to produce. It made little economic sense to supply those theaters which had only mono sound systems with an expensive striped print. Eventually Fox, and others, elected to supply
2664-423: A lensed disk scanner with a 48-line resolution. He was granted U.S. Patent No. 1,544,156 (Transmitting Pictures over Wireless) on 30 June 1925 (filed 13 March 1922). Herbert E. Ives and Frank Gray of Bell Telephone Laboratories gave a dramatic demonstration of mechanical television on 7 April 1927. Their reflected-light television system included both small and large viewing screens. The small receiver had

Constantin Perskyi had coined the word television in a paper read to the International Electricity Congress at the International World Fair in Paris on 24 August 1900. Perskyi's paper reviewed the existing electromechanical technologies, mentioning
2960-515: A medium" dates from 1927. The term telly is more common in the UK. The slang term "the tube" or the "boob tube" derives from the bulky cathode-ray tube used on most TVs until the advent of flat-screen TVs . Another slang term for the TV is "idiot box." Facsimile transmission systems for still photographs pioneered methods of mechanical scanning of images in the early 19th century. Alexander Bain introduced
3108-425: A method of coating 35 mm stock with magnetic stripes and designed a three-channel (left, center, right) system based on three 0.063-inch-wide (1.6 mm) stripes, one on each edge of the film outside the perforations, and one between the picture and the perforations in approximately the position of a standard optical soundtrack. Later it was found possible to add a narrower 0.029 in (0.74 mm) stripe between

In the 1963 Jean-Luc Godard film Contempt ( Le Mepris ), filmmaker Fritz Lang makes a disparaging comment about CinemaScope: "Oh, it wasn't meant for human beings. Just for snakes – and funerals." Ironically, Contempt was shot in Franscope , a process with a similar format to CinemaScope. During
3404-442: A phosphor plate. The phosphor was patterned so the electrons from the guns only fell on one side of the patterning or the other. Using cyan and magenta phosphors, a reasonable limited-color image could be obtained. He also demonstrated the same system using monochrome signals to produce a 3D image (called " stereoscopic " at the time). A demonstration on 16 August 1944 was the first example of a practical color television system. Work on
3552-494: A problem that was soon referred to as "the mumps ". This problem was avoided at first by composing wider shots, but as anamorphic technology lost its novelty, directors and cinematographers sought compositional freedom from these limitations. Issues with the lenses also made it difficult to photograph animation using the CinemaScope process. Nevertheless, many animated short films and a few features were filmed in CinemaScope during
3700-467: A production model was halted by the SCAP after World War II . Because only a limited number of holes could be made in the disks, and disks beyond a certain diameter became impractical, image resolution on mechanical television broadcasts was relatively low, ranging from about 30 lines up to 120 or so. Nevertheless, the image quality of 30-line transmissions steadily improved with technical advances, and by 1933

Mechanically scanned color television was also demonstrated by Bell Laboratories in June 1929 using three complete systems of photoelectric cells , amplifiers, glow-tubes, and color filters, with a series of mirrors to superimpose the red, green, and blue images into one full-color image. The first practical hybrid system was again pioneered by John Logie Baird. In 1940 he publicly demonstrated
4144-591: A radio link from Whippany, New Jersey . Comparing the two transmission methods, viewers noted no difference in quality. Subjects of the telecast included Secretary of Commerce Herbert Hoover . A flying-spot scanner beam illuminated these subjects. The scanner that produced the beam had a 50-aperture disk. The disc revolved at a rate of 18 frames per second, capturing one frame about every 56 milliseconds . (Today's systems typically transmit 30 or 60 frames per second, or one frame every 33.3 or 16.7 milliseconds, respectively.) Television historian Albert Abramson underscored
4292-592: A resolution that was not surpassed until May 1932 by RCA, with 120 lines. On 25 December 1926, Kenjiro Takayanagi demonstrated a television system with a 40-line resolution that employed a Nipkow disk scanner and CRT display at Hamamatsu Industrial High School in Japan. This prototype is still on display at the Takayanagi Memorial Museum in Shizuoka University , Hamamatsu Campus. His research in creating

Unfortunately, an issue with the multipactor was that it wore out at an unsatisfactory rate. At the Berlin Radio Show in August 1931 in Berlin , Manfred von Ardenne gave a public demonstration of a television system using a CRT for both transmission and reception, the first completely electronic television transmission. However, Ardenne had not developed
4588-416: A significant amount of the principal photography was actually filmed using CinemaScope lenses. Fox eventually capitulated completely to third-party lenses. In Like Flint with James Coburn and Caprice with Doris Day , were Fox's final films in CinemaScope. Fox originally intended CinemaScope films to use magnetic stereo sound only, and although in certain areas, such as Los Angeles and New York City,

4736-408: A smaller frame size of approximately 1.34" x 1.06" (34 mm x 27 mm) to allow space for the 6 magnetic soundtracks. Four of these soundtracks (two each side) were outside the perforations, which were further from the edges of the print film than in the negative film; the other two soundtracks were between the perforations and the image. The pull-down for the negative was 8 perforations, while for
4884-410: A static photocell. The thallium sulfide (Thalofide) cell, developed by Theodore Case in the U.S., detected the light reflected from the subject and converted it into a proportional electrical signal. This was transmitted by AM radio waves to a receiver unit, where the video signal was applied to a neon light behind a second Nipkow disk rotating synchronized with the first. The brightness of the neon lamp
5032-459: A system that used a mechanical mirror-drum scanner to transmit, in Zworykin's words, "very crude images" over wires to the " Braun tube" ( cathode-ray tube or "CRT") in the receiver. Moving images were not possible because, in the scanner: "the sensitivity was not enough and the selenium cell was very laggy". In 1921, Édouard Belin sent the first image via radio waves with his belinograph . By

In the remake of 2007, also during Tracy's audition, it was a lyric sung by Amber von Tussle, singing, "This show isn't broadcast in CinemaScope!" in the song "(The Legend of) Miss Baltimore Crabs". Television Television ( TV ) is a telecommunication medium for transmitting moving images and sound. Additionally,
5328-490: A television set. The replacement of earlier cathode-ray tube (CRT) screen displays with compact, energy-efficient, flat-panel alternative technologies such as LCDs (both fluorescent-backlit and LED ), OLED displays, and plasma displays was a hardware revolution that began with computer monitors in the late 1990s. Most television sets sold in the 2000s were still CRT , it was only in early 2010s that flat-screen TVs decisively overtook CRT. Major manufacturers announced
5476-484: A television system using fully electronic scanning and display elements and employing the principle of "charge storage" within the scanning (or "camera") tube. The problem of low sensitivity to light resulting in low electrical output from transmitting or "camera" tubes would be solved with the introduction of charge-storage technology by Kálmán Tihanyi beginning in 1924. His solution was a camera tube that accumulated and stored electrical charges ("photoelectrons") within
5624-582: Is a variation of this process. Another process called Techniscope was developed by Technicolor Inc. in the early 1960s, using normal 35 mm cameras modified for two perforations per (half) frame instead of the regular four and later converted into an anamorphic print. Techniscope was mostly used in Europe , especially with low-budget films. Many European countries and studios used the standard anamorphic process for their wide-screen films, identical in technical specifications to CinemaScope, and renamed to avoid

On 25 March 1925, Baird gave the first public demonstration of televised silhouette images in motion at Selfridges 's department store in London . Since human faces had inadequate contrast to show up on his primitive system, he televised a ventriloquist's dummy named "Stooky Bill," whose painted face had higher contrast, talking and moving. By 26 January 1926, he had demonstrated before members of

#17331365572977696-518: The 1950s, including Walt Disney's Lady and the Tramp (1955). CinemaScope 55 was a large-format version of CinemaScope introduced by Twentieth Century Fox in 1955, which used a film width of 55.625 mm. Fox had introduced the original 35 mm version of CinemaScope in 1953 and it had proved to be commercially successful. But the additional image enlargement needed to fill the new wider screens, which had been installed in theatres for CinemaScope, resulted in visible film grain. A larger film

Finally, the 1976 introduction of Dolby Stereo – which provided similar performance to striped magnetic prints albeit more reliable and at a far lower cost – caused the four-track magnetic system to become totally obsolete. The song "Stereophonic Sound" written by Cole Porter for the 1955 Broadway musical Silk Stockings mentions CinemaScope in

By this point, many of the technical issues in the early sets had been worked out, and the spread of color sets in Europe was fairly rapid. By the mid-1970s, the only stations broadcasting in black-and-white were a few high-numbered UHF stations in small markets and a handful of low-power repeater stations in even smaller markets such as vacation spots. By 1979, even

Camera negative film had larger grain than the film stocks used for prints, so there was a consistent approach in using a larger frame on the film negative than on prints. While the image area of a print has to allow for a soundtrack, a camera negative does not. CinemaScope 55 had different frame dimensions for the camera negative and struck prints. The negative film had
8288-613: The Dutch company Philips produced and commercialized the image iconoscope and multicon from 1952 to 1958. U.S. television broadcasting, at the time, consisted of a variety of markets in a wide range of sizes, each competing for programming and dominance with separate technology until deals were made and standards agreed upon in 1941. RCA, for example, used only Iconoscopes in the New York area, but Farnsworth Image Dissectors in Philadelphia and San Francisco. In September 1939, RCA agreed to pay

With this historic agreement in place, RCA integrated much of what was best about the Farnsworth Technology into their systems. In 1941, the United States implemented 525-line television. Electrical engineer Benjamin Adler played a prominent role in the development of television. The world's first 625-line television standard

Until June 1990, the Japanese MUSE standard, based on an analog system, was the front-runner among the more than 23 other technical concepts under consideration. Then, a U.S. company, General Instrument, demonstrated
10508-535: The discontinuation of CRT, Digital Light Processing (DLP), plasma, and even fluorescent-backlit LCDs by the mid-2010s. LEDs are being gradually replaced by OLEDs. Also, major manufacturers have started increasingly producing smart TVs in the mid-2010s. Smart TVs with integrated Internet and Web 2.0 functions became the dominant form of television by the late 2010s. Television signals were initially distributed only as terrestrial television using high-powered radio-frequency television transmitters to broadcast
10656-421: The extra information in the signal and produce a limited-resolution color display. The higher-resolution black-and-white and lower-resolution color images combine in the brain to produce a seemingly high-resolution color image. The NTSC standard represented a significant technical achievement. The first color broadcast (the first episode of the live program The Marriage ) occurred on 8 July 1954. However, during
10804-468: The facsimile machine between 1843 and 1846. Frederick Bakewell demonstrated a working laboratory version in 1851. Willoughby Smith discovered the photoconductivity of the element selenium in 1873. As a 23-year-old German university student, Paul Julius Gottlieb Nipkow proposed and patented the Nipkow disk in 1884 in Berlin . This was a spinning disk with a spiral pattern of holes, so each hole scanned
10952-439: The first film with stereophonic sound, had used Disney's Fantasound system, which utilized a three-channel soundtrack played from separate optical film. Early post-war stereo systems used with Cinerama and some 3-D films had used multichannel audio played from a separate magnetic film. Fox had initially intended to use three-channel stereo from magnetic film for CinemaScope. However, Hazard E. Reeves ' sound company had devised
11100-440: The first outdoor remote broadcast of The Derby . In 1932, he demonstrated ultra-short wave television. Baird's mechanical system reached a peak of 240 lines of resolution on BBC telecasts in 1936, though the mechanical system did not scan the televised scene directly. Instead, a 17.5 mm film was shot, rapidly developed, and then scanned while the film was still wet. A U.S. inventor, Charles Francis Jenkins , also pioneered
11248-431: The following ten years, most network broadcasts and nearly all local programming continued to be black-and-white. It was not until the mid-1960s that color sets started selling in large numbers, due in part to the color transition of 1965, in which it was announced that over half of all network prime-time programming would be broadcast in color that fall. The first all-color prime-time season came just one year later. In 1972,
11396-417: The iconoscope (or Emitron) produced an electronic signal and concluded that its real efficiency was only about 5% of the theoretical maximum. They solved this problem by developing and patenting in 1934 two new camera tubes dubbed super-Emitron and CPS Emitron . The super-Emitron was between ten and fifteen times more sensitive than the original Emitron and iconoscope tubes, and, in some cases, this ratio
11544-417: The image was expanded horizontally when projected meant that there could be visible graininess and brightness problems. To combat this, larger film formats were developed (initially a too-costly 55 mm for Carousel and The King and I ) and then abandoned (both films were eventually reduction printed at 35 mm, although the aspect ratio was kept at 2.55:1). Later Fox re-released The King and I in
11692-669: The industrial standard for public broadcasting in Europe from 1936 until 1960, when it was replaced by the vidicon and plumbicon tubes. Indeed, it represented the European tradition in electronic tubes competing against the American tradition represented by the image orthicon. The German company Heimann produced the Superikonoskop for the 1936 Berlin Olympic Games, later Heimann also produced and commercialized it from 1940 to 1955; finally
11840-437: The invention of the first working transistor at Bell Labs , Sony founder Masaru Ibuka predicted in 1952 that the transition to electronic circuits made of transistors would lead to smaller and more portable television sets. The first fully transistorized, portable solid-state television set was the 8-inch Sony TV8-301 , developed in 1959 and released in 1960. This began the transformation of television viewership from
11988-401: The last holdout among daytime network programs converted to color, resulting in the first completely all-color network season. Early color sets were either floor-standing console models or tabletop versions nearly as bulky and heavy, so in practice they remained firmly anchored in one place. GE 's relatively compact and lightweight Porta-Color set was introduced in the spring of 1966. It used
12136-464: The last of these had converted to color. By the early 1980s, B&W sets had been pushed into niche markets, notably low-power uses, small portable sets, or for use as video monitor screens in lower-cost consumer equipment. By the late 1980s, even these last holdout niche B&W environments had inevitably shifted to color sets. Digital television (DTV) is the transmission of audio and video by digitally processed and multiplexed signals, in contrast to
12284-458: The late 1950s with the introduction of faster film stocks, but was revived by Industrial Light & Magic in 1975 to create high quality visual effects for Star Wars and ILM's subsequent film projects. RKO used the Superscope process in which the standard 35 mm image was cropped and then optically squeezed in post-production to create an anamorphic image on film. Today's Super 35
12432-404: The lyrics. The first verse is: "Today to get the public to attend the picture show/ It's not enough to advertise a famous star they know/ If you wanna get the crowds to come around/ You gotta have glorious Technicolor/ Breathtaking CinemaScope and stereophonic sound." The musical was adapted for film in 1957 and was indeed filmed in CinemaScope. (Although the song refers to Technicolor , the film
12580-427: The majority of their prints in standard mono optical sound form, with magnetic striped prints reserved for those theaters capable of playing them. Magnetic-striped prints were expensive to produce; each print cost at least twice as much as a print with a standard optical soundtrack only. Furthermore, these striped prints wore out faster than optical prints and caused more problems in use, such as flakes of oxide clogging
12728-439: The motion picture industry in his invention but, at that time, the industry was not sufficiently impressed. By 1950, however, cinema attendance seriously declined with the advent of a new competitive rival: television . Yet Cinerama and the early 3D films , both launched in 1952, succeeded in defying that trend, which in turn persuaded Spyros Skouras , the head of 20th Century-Fox , that technical innovation could help to meet
12876-438: The new anamorphic format and filling in the gap created by Bausch and Lomb 's inability to mass-produce the needed adapters for movie theaters fast enough. Looking to expand beyond projector lenses, Panavision founder Robert Gottschalk soon improved upon the anamorphic camera lenses by creating a new lens set that included dual rotating anamorphic elements which were interlocked with the lens focus gearing. This innovation allowed
13024-559: The optical center of the projected image. All of Fox's CinemaScope films were made using a silent/full aperture for the negatives, as was this studio's practice for all films, whether anamorphic or not. In order to better hide so-called negative assembly splices, the ratio of the image was later changed by others to 2.39:1 (1024:429). All professional cameras are capable of shooting 2.55:1 (special 'Scope aperture plate) or 2.66:1 (standard Full/Silent aperture plate, preferred by many producers and all optical houses), and 2.35:1 or 2.39:1 or 2.40:1
13172-466: The original Campbell-Swinton's selenium-coated plate. Although others had experimented with using a cathode-ray tube as a receiver, the concept of using one as a transmitter was novel. The first cathode-ray tube to use a hot cathode was developed by John B. Johnson (who gave his name to the term Johnson noise ) and Harry Weiner Weinhart of Western Electric , and became a commercial product in 1922. In 1926, Hungarian engineer Kálmán Tihanyi designed
13320-610: The original anamorphic CinemaScope lenses, was contracted by Fox to build new Super CinemaScope lenses that could cover the larger film frame. Fox shot two of their Rodgers and Hammerstein musical series in CinemaScope ;55: Carousel , and The King and I . But it did not make 55 mm release prints for either film; both were released in conventional 35 mm CinemaScope with a limited release of The King and I being shown in 70 mm. The company substituted Todd-AO for its wide-gauge production process, having acquired
13468-453: The perforations (of the CS Fox-hole type) close to the edge of the film and the camera aperture was 1.824" by 1.430" (approx. 46 mm x 36 mm), giving an image area of 2.61 sq. inch. This compares to the 0.866" by 0.732" (approx. 22 mm x 18.6 mm) frame of a modern anamorphic 35 mm negative, which provides a frame area of 0.64 sq. inch. On the print film, however, there was
13616-456: The phosphors deposited on their outside faces instead of Baird's 3D patterning on a flat surface. The Penetron used three layers of phosphor on top of each other and increased the power of the beam to reach the upper layers when drawing those colors. The Chromatron used a set of focusing wires to select the colored phosphors arranged in vertical stripes on the tube. One of the great technical challenges of introducing color broadcast television
13764-442: The picture and perforations on the other side of the film; this fourth track was used for a surround channel, also sometimes known at the time as an effects channel. In order to avoid hiss on the surround/effects channel from distracting the audience the surround speakers were switched on by a 12 kHz tone recorded on the surround track only while wanted surround program material was present. This four-track magnetic sound system
13912-408: The prime lens and the anamorphic lens in one unit (initially in 35, 40, 50, 75, 100 and 152 mm focal lengths, later including a 25 mm focal length). The combined lenses continue to be used to this day, particularly in special effects units. Other manufacturers' lenses are often preferred for so-called production applications that benefit from significantly lighter weight or lower distortion, or
14060-486: The process had expired, so Fox purchased his existing Hypergonars, and the lenses were flown to Fox's studios in Hollywood. Test footage shot with the lenses was screened for Skouras, who gave the go-ahead for development of a widescreen process, based on Chrétien's invention, which was to be known as CinemaScope. 20th Century-Fox's pre-production of The Robe , originally committed to Technicolor three-strip origination,
14208-442: The process would be adopted widely, a number of films were shot simultaneously with anamorphic and regular lenses. Despite early success with the process, Fox did not shoot every production by this process. They reserved CinemaScope as a trade name for their A productions, while B productions in black and white were begun in 1956 at Fox under the trade name, RegalScope. The latter used the very same optics as CinemaScope, but, usually,
14356-489: The production of 1999's The Iron Giant , director Brad Bird wanted to advertise the film with the CinemaScope name and logo, but Fox would not allow its use. A reference to CinemaScope was included during the end credits of the 2015 " Signature Edition " re-release. In the 1988 film Hairspray and the 2007 remake , there are references to CinemaScope. In both instances, they are comments made in regard to Tracy Turnblad's weight, implying that she's too big to be seen on
14504-507: The public at this time, viewing of the color field tests was restricted to RCA and CBS engineers and the invited press. The War Production Board halted the manufacture of television and radio equipment for civilian use from 22 April 1942 to 20 August 1945, limiting any opportunity to introduce color television to the general public. As early as 1940, Baird had started work on a fully electronic system he called Telechrome . Early Telechrome devices used two electron guns aimed at either side of
14652-405: The ratio of the image was reduced to 2.55:1. This reduction was kept to a minimum by reducing the width of the normal KS perforations so that they were nearly square, but of DH height. This was the CinemaScope, or CS, perforation , known colloquially as fox-holes. Later still an optical soundtrack was added, further reducing the aspect ratio to 2.35:1 (1678:715). This change also meant a shift in
14800-512: The receiver, a type of Kerr cell modulated the light, and a series of differently angled mirrors attached to the edge of a rotating disc scanned the modulated beam onto the display screen. A separate circuit regulated synchronization. The 8x8 pixel resolution in this proof-of-concept demonstration was just sufficient to clearly transmit individual letters of the alphabet. An updated image was transmitted "several times" each second. In 1911, Boris Rosing and his student Vladimir Zworykin created
14948-451: The replay heads. Due to these problems, and also because many cinemas never installed the necessary playback equipment, magnetic-sound prints started to be made in small quantities for roadshow screenings only, with the main release using standard mono optical-sound prints. As time went by roadshow screenings were increasingly made using 70 mm film , and the use of striped 35 mm prints declined further. Many CinemaScope films from
15096-415: The reproducer) marked the start of the end for mechanical systems as the dominant form of television. Mechanical television, despite its inferior image quality and generally smaller picture, would remain the primary television technology until the 1930s. The last mechanical telecasts ended in 1939 at stations run by a lot of public universities in the United States. In 1897, English physicist J. J. Thomson
15244-435: The requirement of two camera assistants. Bausch & Lomb, Fox's prime contractor for the production of the lenses, initially produced an improved Chrétien-formula adapter lens design (CinemaScope Adapter Type I), and subsequently produced a dramatically improved and patented Bausch & Lomb formula adapter lens design (CinemaScope Adapter Type II). Ultimately, Bausch & Lomb formula combined lens designs incorporated both
15392-561: The resolution of the color information to conserve bandwidth. As black-and-white televisions could receive the same transmission and display it in black-and-white, the color system adopted is [backwards] "compatible." ("Compatible Color," featured in RCA advertisements of the period, is mentioned in the song " America ," of West Side Story , 1957.) The brightness image remained compatible with existing black-and-white television sets at slightly reduced resolution. In contrast, color televisions could decode
15540-558: The results of some "not very successful experiments" he had conducted with G. M. Minchin and J. C. M. Stanton. They had attempted to generate an electrical signal by projecting an image onto a selenium-coated metal plate that was simultaneously scanned by a cathode ray beam. These experiments were conducted before March 1914, when Minchin died, but they were later repeated by two different teams in 1937, by H. Miller and J. W. Strange from EMI , and by H. Iams and A. Rose from RCA . Both teams successfully transmitted "very faint" images with
15688-429: The screen rights in May 1955 and assigned it to Richard Whorf to produce. Irving Wallace wrote the script and John Wayne was announced as a possible star. In December 1955 Tab Hunter was assigned to the lead. The book ended up selling over a million copies. Filming started February 1956. Variety said "With the youthful filmgoer in mind, the combo of Tab Hunter and Natalie Wood in “The Burning Hills” could prove to be
15836-458: The shortened form, ' Scope , is still widely used by both filmmakers and projectionists, although today it generally refers to any 2.35:1, 2.39:1, 2.40:1, or 2.55:1 presentation or, sometimes, the use of anamorphic lensing or projection in general. Bausch & Lomb won a 1954 Oscar for its development of the CinemaScope lens. French inventor Henri Chrétien developed and patented a new film process that he called Anamorphoscope in 1926. It
15984-449: The signal to individual television receivers. Alternatively, television signals are distributed by coaxial cable or optical fiber , satellite systems, and, since the 2000s, via the Internet. Until the early 2000s, these were transmitted as analog signals, but a transition to digital television was expected to be completed worldwide by the late 2010s. A standard television set consists of multiple internal electronic circuits , including
16132-576: The significance of the Bell Labs demonstration: "It was, in fact, the best demonstration of a mechanical television system ever made to this time. It would be several years before any other system could even begin to compare with it in picture quality." In 1928, WRGB , then W2XB, was started as the world's first television station. It broadcast from the General Electric facility in Schenectady, NY . It
16280-400: The smaller frame on the print film, it was 6 perforations. In both cases, however, the frame had an aspect ratio of 1.275:1, which when expanded by a 2:1 anamorphic lens resulted in an image of 2.55:1. A camera originally built for the obsolete Fox 70 mm Grandeur film format more than 20 years before was modified to work with the new 55 mm film. Bausch & Lomb , the firm that created
16428-634: The spectrum of colors at the transmitting end and could not have worked as he described it. Another inventor, Hovannes Adamian , also experimented with color television as early as 1907. The first color television project is claimed by him, and was patented in Germany on 31 March 1908, patent No. 197183, then in Britain, on 1 April 1908, patent No. 7219, in France (patent No. 390326) and in Russia in 1910 (patent No. 17912). Scottish inventor John Logie Baird demonstrated
16576-404: The standard four-track stereo soundtrack (sounded on the actual film) as was then used in all CinemaScope releases. In 2005, both CinemaScope 55 films were restored from the original 55 mm negatives. Lens manufacturer Panavision was initially founded in late 1953 as a manufacturer of anamorphic lens adapters for movie projectors screening CinemaScope films, capitalizing on the success of
16724-546: The system was improved further by eliminating a motor generator so that his television system had no mechanical parts. That year, Farnsworth transmitted the first live human images with his system, including a three and a half-inch image of his wife Elma ("Pem") with her eyes closed (possibly due to the bright lighting required). Meanwhile, Vladimir Zworykin also experimented with the cathode-ray tube to create and show images. While working for Westinghouse Electric in 1923, he began to develop an electronic camera tube. However, in
16872-525: The television challenge. Skouras tasked Earl Sponable, head of Fox's research department, with devising a new, impressive, projection system, but something that, unlike Cinerama, could be retrofitted to existing theatres at a relatively modest cost. Herbert Brag, Sponable's assistant, remembered Chrétien's hypergonar lens. The optical company Bausch & Lomb was asked to produce a prototype "anamorphoser" (later shortened to anamorphic) lens. Meanwhile, Sponable tracked down Professor Chrétien, whose patent for
17020-625: The television. He published an article on "Motion Pictures by Wireless" in 1913, transmitted moving silhouette images for witnesses in December 1923, and on 13 June 1925, publicly demonstrated synchronized transmission of silhouette pictures. In 1925, Jenkins used the Nipkow disk and transmitted the silhouette image of a toy windmill in motion over a distance of 5 miles (8 km), from a naval radio station in Maryland to his laboratory in Washington, D.C., using
17168-413: The term can refer to a physical television set rather than the medium of transmission . Television is a mass medium for advertising, entertainment, news, and sports. The medium is capable of more than " radio broadcasting ," which refers to an audio signal sent to radio receivers . Television became available in crude experimental forms in the 1920s, but only after several years of further development
17316-537: The term dates back to 1900, when the Russian scientist Constantin Perskyi used it in a paper that he presented in French at the first International Congress of Electricity, which ran from 18 to 25 August 1900 during the International World Fair in Paris. The anglicized version of the term is first attested in 1907, when it was still "...a theoretical system to transmit moving images over telegraph or telephone wires ". It
17464-625: The town of Esperanza, Trace sees a destroyed sheriff's office and discovers the only law in Esperanza is Joe Sutton. He also discovers that the stolen horses have been rebranded with the Sutton brand, and their riders who match the description of their tracks work for Sutton. Trace enters Joe Sutton's ranch and wounds him in a shooting. The enraged Sutton sends his son Jack, his foreman Ben and ten ranch hands to track down Trace before he goes to an Army fort to bring law to Esperanza. Wounded in his escape, Trace
17612-486: The trademarks of Fox . Some of these include Euroscope, Franscope, and Naturama (the latter used by Republic Pictures ). In 1953, Warner Bros. also planned to develop an identical anamorphic process called Warnerscope but, after the premiere of CinemaScope, Warner Bros. decided to license it from Fox instead. Although CinemaScope was capable of producing a 2.66:1 image, the addition of magnetic sound tracks for multi-channel sound reduced this to 2.55:1. The fact that
17760-513: The tube throughout each scanning cycle. The device was first described in a patent application he filed in Hungary in March 1926 for a television system he called "Radioskop". After further refinements included in a 1928 patent application, Tihanyi's patent was declared void in Great Britain in 1930, so he applied for patents in the United States. Although his breakthrough would be incorporated into
17908-513: The use of a CRT as a display device. The Braun tube became the foundation of 20th century television. In 1906 the Germans Max Dieckmann and Gustav Glage produced raster images for the first time in a CRT. In 1907, Russian scientist Boris Rosing used a CRT in the receiving end of an experimental video signal to form a picture. He managed to display simple geometric shapes onto the screen. In 1908, Alan Archibald Campbell-Swinton ,
18056-654: The vast majority of theaters were equipped for four-track magnetic sound (four-track magnetic sound achieving nearly 90 percent penetration of theaters in the greater Los Angeles area) the owners of many smaller theaters were dissatisfied with contractually having to install expensive three- or four-track magnetic stereo, and because of the technical nature of sound installations, drive-in theaters had trouble presenting stereophonic sound at all. Due to these conflicts, and because other studios were starting to release anamorphic prints with standard optical soundtracks, Fox revoked their policy of stereo-only presentations in 1957, and added
18204-487: The widespread adoption of television. On 7 September 1927, U.S. inventor Philo Farnsworth 's image dissector camera tube transmitted its first image, a simple straight line, at his laboratory at 202 Green Street in San Francisco. By 3 September 1928, Farnsworth had developed the system sufficiently to hold a demonstration for the press. This is widely regarded as the first electronic television demonstration. In 1929,
18352-430: The work of Nipkow and others. However, it was not until 1907 that developments in amplification tube technology by Lee de Forest and Arthur Korn , among others, made the design practical. The first demonstration of the live transmission of images was by Georges Rignoux and A. Fournier in Paris in 1909. A matrix of 64 selenium cells, individually wired to a mechanical commutator , served as an electronic retina . In
18500-457: The world's first color transmission on 3 July 1928, using scanning discs at the transmitting and receiving ends with three spirals of apertures, each spiral with filters of a different primary color, and three light sources at the receiving end, with a commutator to alternate their illumination. Baird also made the world's first color broadcast on 4 February 1938, sending a mechanically scanned 120-line image from Baird's Crystal Palace studios to
18648-541: The world's first public demonstration of an all-electronic television system, using a live camera, at the Franklin Institute of Philadelphia on 25 August 1934 and for ten days afterward. Mexican inventor Guillermo González Camarena also played an important role in early television. His experiments with television (known as telectroescopía at first) began in 1931 and led to a patent for the "trichromatic field sequential system" color television in 1940. In Britain,
18796-458: Was "...formed in English or borrowed from French télévision ." In the 19th century and early 20th century, other "...proposals for the name of a then-hypothetical technology for sending pictures over distance were telephote (1880) and televista (1904)." The abbreviation TV is from 1948. The use of the term to mean "a television set " dates from 1941. The use of the term to mean "television as
18944-454: Was able, in his three well-known experiments, to deflect cathode rays, a fundamental function of the modern cathode-ray tube (CRT). The earliest version of the CRT was invented by the German physicist Ferdinand Braun in 1897 and is also known as the "Braun" tube. It was a cold-cathode diode , a modification of the Crookes tube , with a phosphor -coated screen. Braun was the first to conceive
19092-593: Was actually made in Metrocolor .) While the lens system has been retired for decades, Fox has used the trademark in recent years for a few films films: Down with Love , which was shot with Panavision optics but used the credit as a throwback to the films it references, the Don Bluth films Anastasia and Titan A.E. at Bluth's insistence. However these films are not in true CinemaScope because they use modern lenses. CinemaScope's association with anamorphic projection
19240-481: Was also used for some non-CinemaScope films; for example Fantasia was re-released in 1956, 1963, and 1969 with the original Fantasound track transferred to four-track magnetic. CinemaScope itself was a response to early realism processes Cinerama and 3-D . Cinerama was relatively unaffected by CinemaScope, as it was a quality-controlled process that played in select venues, similar to the IMAX films of later years. 3-D
19388-509: Was considerably greater. It was used for outside broadcasting by the BBC, for the first time, on Armistice Day 1937, when the general public could watch on a television set as the King laid a wreath at the Cenotaph. This was the first time that anyone had broadcast a live street scene from cameras installed on the roof of neighboring buildings because neither Farnsworth nor RCA would do the same until
19536-637: Was designed in the Soviet Union in 1944 and became a national standard in 1946. The first broadcast in 625-line standard occurred in Moscow in 1948. The concept of 625 lines per frame was subsequently implemented in the European CCIR standard. In 1936, Kálmán Tihanyi described the principle of plasma display , the first flat-panel display system. Early electronic television sets were large and bulky, with analog circuits made of vacuum tubes . Following
19684-503: Was halted so that the film could be changed to a CinemaScope production (using Eastmancolor , but processed by Technicolor). The use of the CinemaScope technology became a key feature of the film's marketing campaign. Two other CinemaScope productions were also planned: How to Marry a Millionaire and Beneath the Twelve-Mile Reef . So that production of the first CinemaScope films could proceed without delay, shooting started using
19832-465: Was hurt, however, by studio advertising surrounding CinemaScope's promise that it was the "miracle you see without glasses." Technical difficulties in presentation spelled the true end for 3-D, but studio hype was quick to hail it a victory for CinemaScope. In April 1953, a technique simply now known as wide-screen appeared and was soon adopted as a standard by all flat film productions in the US. In this process,
19980-411: Was more reliable and visibly superior. This was the world's first regular "high-definition" television service. The original U.S. iconoscope was noisy, had a high ratio of interference to signal, and ultimately gave disappointing results, especially compared to the high-definition mechanical scanning systems that became available. The EMI team, under the supervision of Isaac Shoenberg , analyzed how
20128-409: Was not owned or licensed-out by a rival studio. Confusingly, some studios, particularly MGM, continued to use the CinemaScope credit even though they had switched to Panavision lenses. Virtually all MGM CinemaScope films after 1958 are actually in Panavision. By 1967, even Fox had begun to abandon CinemaScope for Panavision (famously at the demand of Frank Sinatra for Von Ryan's Express ), although
20276-408: Was not until the 1990s that digital television became possible. Digital television was previously not practically possible due to the impractically high bandwidth requirements of uncompressed digital video , requiring around 200 Mbit/s for a standard-definition television (SDTV) signal, and over 1 Gbit/s for high-definition television (HDTV). A digital television service
20424-410: Was one by Maurice Le Blanc in 1880 for a color system, including the first mentions in television literature of line and frame scanning. Polish inventor Jan Szczepanik patented a color television system in 1897, using a selenium photoelectric cell at the transmitter and an electromagnet controlling an oscillating mirror and a moving prism at the receiver. But his system contained no means of analyzing
20572-842: Was partly mechanical, with a disc made of red, blue, and green filters spinning inside the television camera at 1,200 rpm and a similar disc spinning in synchronization in front of the cathode-ray tube inside the receiver set. The system was first demonstrated to the Federal Communications Commission (FCC) on 29 August 1940 and shown to the press on 4 September. CBS began experimental color field tests using film as early as 28 August 1940 and live cameras by 12 November. NBC (owned by RCA) made its first field test of color television on 20 February 1941. CBS began daily color field tests on 1 June 1941. These color systems were not compatible with existing black-and-white television sets , and, as no color television sets were available to
20720-518: Was popularly known as " WGY Television." Meanwhile, in the Soviet Union , Leon Theremin had been developing a mirror drum-based television, starting with 16 lines resolution in 1925, then 32 lines, and eventually 64 using interlacing in 1926. As part of his thesis, on 7 May 1926, he electrically transmitted and then projected near-simultaneous moving images on a 5-square-foot (0.46 m ) screen. By 1927 Theremin had achieved an image of 100 lines,
20868-512: Was proposed in 1986 by Nippon Telegraph and Telephone (NTT) and the Ministry of Posts and Telecommunication (MPT) in Japan, where there were plans to develop an "Integrated Network System" service. However, it was not possible to implement such a digital television service practically until the adoption of DCT video compression technology made it possible in the early 1990s. In the mid-1980s, as Japanese consumer electronics firms forged ahead with
21016-489: Was released first. 20th Century-Fox used its influential people to promote CinemaScope. With the success of The Robe and How to Marry a Millionaire, the process enjoyed success in Hollywood . Fox licensed the process to many of the major American film studios . Walt Disney Productions was one of the first companies to license the CinemaScope process from Fox. Among the features and shorts they filmed with it, they created
21164-426: Was that process which later formed the basis of CinemaScope. Chrétien's process used lenses that employed an optical trick, which produced an image twice as wide as those that were being produced with conventional lenses. That was done using an optical system called Hypergonar , which compressed the image laterally when the film was being shot, and dilated it when the film was projected. Chrétien attempted to interest
21312-500: Was the desire to conserve bandwidth , potentially three times that of the existing black-and-white standards, and not use an excessive amount of radio spectrum . In the United States, after considerable research, the National Television Systems Committee approved an all-electronic system developed by RCA , which encoded the color information separately from the brightness information and significantly reduced
21460-465: Was the new technology marketed to consumers. After World War II , an improved form of black-and-white television broadcasting became popular in the United Kingdom and the United States, and television sets became commonplace in homes, businesses, and institutions. During the 1950s, television was the primary medium for influencing public opinion . In the mid-1960s, color broadcasting was introduced in
21608-500: Was unable or unwilling to introduce evidence of a working model of his tube that was based on his 1923 patent application. In September 1939, after losing an appeal in the courts and being determined to go forward with the commercial manufacturing of television equipment, RCA agreed to pay Farnsworth US$ 1 million over ten years, in addition to license payments, to use his patents. In 1933, RCA introduced an improved camera tube that relied on Tihanyi's charge storage principle. Called
21756-504: Was used to reduce the need for such enlargement. CinemaScope 55 was developed to satisfy this need and was one of three high-definition film systems introduced in the mid-1950s, the other two being Paramount 's VistaVision and the Todd-AO 70 mm film system. Fox determined that a system that produced a frame area approximately 4 times that of the 35mm CinemaScope frame would be the optimal trade-off between performance and cost, and it chose
21904-419: Was varied in proportion to the brightness of each spot on the image. As each hole in the disk passed by, one scan line of the image was reproduced. Baird's disk had 30 holes, producing an image with only 30 scan lines, just enough to recognize a human face. In 1927, Baird transmitted a signal over 438 miles (705 km) of telephone line between London and Glasgow . Baird's original 'televisor' now resides in
