SelectaVision
SelectaVision was a trademark name used on four classes of device by the Radio Corporation of America: * The Holotape, a prototype video medium * Magnetic tape * VHS videocassette recorders, and * Capacitance Electronic Disc videodisc players and the discs themselves, introduced in 1981. Capacitance Electronic Disc's competitors, Philips/Magnavox and Pioneer, instead manufactured optical discs, read with lasers.On April 4, 1984, RCA, having sold only 550,000 players, ended sales, losing $580 million. The losses resulted in General Electric's acquisition of RCA in 1986, and the "SelectaVision" brand was abandoned.

Capacitance Electronic Disc
The Capacitance Electronic Disc (CED) is an analog video disc playback system developed by Radio Corporation of America (RCA), in which video and audio could be played back on a TV set using a special stylus and high-density groove system similar to phonograph records. First conceived in 1964, the CED system was widely seen as a technological success which was able to increase the density of a long-playing record by two orders of magnitude. Despite this achievement, the CED system fell victim to poor planning, various conflicts with RCA management, and several technical difficulties that slowed development and stalled production of the system for 17 years—until 1981, by which time it had already been made obsolete by laser videodisc ( DiscoVision, later called LaserVision and LaserDisc) as well as Betamax and VHS video cassette formats. Sales for the system were nowhere near projected estimates. In the spring of 1984, RCA announced it was discontinuing player production, ...

Radio Corporation Of America
RCA Corporation was a major American electronics company, which was founded in 1919 as the Radio Corporation of America. It was initially a patent pool, patent trust owned by General Electric (GE), Westinghouse Electric Corporation, Westinghouse, AT&T Corporation and United Fruit Company. In 1932, RCA became an independent company after the partners were required to divest their ownership as part of the settlement of a government United States antitrust law, antitrust suit. An innovative and progressive company, RCA was the dominant electronics and communications firm in the United States for over five decades. In the early 1920s, RCA was at the forefront of the mushrooming radio industry as a major manufacturer of radio receivers, and the exclusive manufacturer of the first superheterodyne sets. The company also created the first nationwide American radio network, the National Broadcasting Company (NBC). RCA was also a pioneer in the introduction and development of television, ...

Phonovision
Phonovision was a patented concept to create pre-recorded mechanically scanned television recordings on gramophone records. Attempts at developing Phonovision were undertaken in the late 1920s in London by its inventor, Scottish television pioneer John Logie Baird. The objective was not simply to record video, but to record it synchronously, as Baird intended playback from an inexpensive playback device, which he called a 'Phonovisor'. Baird stated that he had several records made of the sound of the vision signal but that the quality was poor. Unlike Baird's other experiments (including stereoscopy, colour and infra-red night-vision), there is no evidence of him having demonstrated playback of pictures, though he did play back the sound of the vision signal to audiences. Baird moved on leaving behind several discs in the hands of museums and favoured company members. Until 1982, this was the extent of knowledge regarding Phonovision. Discoveries and restoration From 1982, Donald ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Home Video
Home video is recorded media sold or Video rental shop, rented for home viewing. The term originates from the VHS and Betamax era, when the predominant medium was videotapes, but has carried over to optical disc formats such as DVD and Blu-ray. In a different usage, "home video" refers to amateur video recordings, also known as home movies. Released in 1978, LaserDisc (LD) is another home video format, which never managed to gain widespread use on North American and European retail markets due to high cost of the players and their inability to record TV programs (unlike the VHS), although it retained some popularity among videophiles and Cinephilia, film enthusiasts during its lifespan; the format had greater prevalence in some regions of Southeast Asia such as Japan, Hong Kong, Singapore and Malaysia where it was better supported. Film titles were released in LD format until 2001, production of LD players ceased in 2009. The home video business distributes films, television ser ...

Magnetic Tape
Magnetic tape is a medium for magnetic storage made of a thin, magnetizable coating on a long, narrow strip of plastic film. It was developed in Germany in 1928, based on the earlier magnetic wire recording from Denmark. Devices that use magnetic tape can with relative ease record and play back audio, visual, and binary computer data. Magnetic tape revolutionized sound recording and reproduction and broadcasting. It allowed radio, which had always been broadcast live, to be recorded for later or repeated airing. Since the early 1950s, magnetic tape has been used with computers to store large quantities of data and is still used for backup purposes. Magnetic tape begins to degrade after 10–20 years and therefore is not an ideal medium for long-term archival storage. The exception is data tape formats like Linear Tape-Open, LTO which are specifically designed for long-term archiving. Information in magnetic tapes is often recorded in tracks which are narrow and long areas of in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Videocassette
Videotape is magnetic tape used for storing video and usually sound in addition. Information stored can be in the form of either an analog or digital signal. Videotape is used in both video tape recorders (VTRs) and, more commonly, videocassette recorders (VCRs) and camcorders. Videotapes have also been used for storing scientific or medical data, such as the data produced by an electrocardiogram. Because video signals have a very high bandwidth, and stationary heads would require extremely high tape speeds, in most cases, a helical-scan video head rotates against the moving tape to record the data in two dimensions. Tape is a linear method of storing information and thus imposes delays to access a portion of the tape that is not already against the heads. The early 2000s saw the introduction and rise to prominence of high-quality random-access video recording media such as hard disks and flash memory. Since then, videotape has been increasingly relegated to archival and s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
General Electric
General Electric Company (GE) was an American Multinational corporation, multinational Conglomerate (company), conglomerate founded in 1892, incorporated in the New York (state), state of New York and headquartered in Boston. Over the years, the company had multiple divisions, including GE Aerospace, aerospace, GE Power, energy, GE HealthCare, healthcare, lighting, locomotives, appliances, and GE Capital, finance. In 2020, GE ranked among the Fortune 500, ''Fortune'' 500 as the 33rd largest firm in the United States by gross revenue. In 2023, the company was ranked 64th in the Forbes Global 2000, ''Forbes'' Global 2000. In 2011, GE ranked among the Fortune 20 as the 14th most profitable company, but later very severely underperformed the market (by about 75%) as its profitability collapsed. Two employees of GE—Irving Langmuir (1932) and Ivar Giaever (1973)—have been awarded the Nobel Prize. From 1986 until 2013, GE was the owner of the NBC television network through its ...

Video High Density
Video High Density (VHD) was an analog video disc format storing up to 60 minutes per side, predominantly marketed by JVC in Japan. In contrast to the optical LaserDisc format, the VHD format was read with a physical stylus. Facing numerous competing formats outside Japan, the reach of VHD remained very limited. History VHD was first demonstrated in 1978. After numerous advertisements in 1981/1982 '' National Geographic'' magazines, it was eventually released in Japan on April 21, 1983. By this time, both LaserDisc and CED were already suffering from the onslaught of VHS and Betamax VCRs. Despite demonstrating the player at several Consumer Electronics Shows, JVC opted not to release VHD as a consumer product in North America. In the UK, Thorn EMI, which was the leading consumer provider of the VHS tape system, saw VHD as the next step in the market and committed to the system. In 1981 it invested in a factory to press discs (in Swindon) and a production unit to develop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronic Video Recording
Electronic Video Recording, or EVR, was a film-based video recording format developed by Hungarian-born engineer Peter Carl Goldmark at CBS Laboratories in the 1960s. Intended to be used primarily for educational and household use as a method of storing large amounts of videos and papers without taking up as much space as other media forms. CBS announced the development of EVR on August 27, 1967. The 750-foot film was stored on a spool in a plastic cartridge. It used a twin-track 8.75 mm film onto which video signals were transferred by electron beam recording, two monochrome tracks in the same direction of travel. Some EVR films had a separate chroma track in place of the second program monochrome track for color EVR films. The images stored on an EVR film were visible frames much like motion picture film, and were read by a flying-spot scanner inside an EVR player to be converted to a video signal to be sent to a television set. EVR was also released by CBS as a prof ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vitascan
{{More citations needed, date=July 2021 Vitascan (sometimes alternately spelled VitaScan) was an early color television camera system developed by American television equipment manufacturer DuMont Laboratories. Development began in 1949 and the product was released on an experimental basis in 1956 Events January * January 1 – The Anglo-Egyptian Sudan, Anglo-Egyptian Condominium ends in Sudan after 57 years. * January 8 – Operation Auca: Five U.S. evangelical Christian Missionary, missionaries, Nate Saint, Roger Youderian, E .... Vitascan was fully compatible with the NTSC color system, and DuMont Labs hoped the system would catch on in the television industry. However, Vitascan cameras only worked indoors, due to Vitascan being in essence a flying-spot scanner based system. The system's camera basically worked in reverse by projecting a light through the camera's lens onto the subject from a cathode ray tube, or CRT, mounted behind the lens (instead of a pickup t ...
