CED Videodisc
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, ...

Betamax
Betamax (also known as Beta, and stylized as the Greek letter Beta, β in its logo) is a discontinued consumer analog Videotape, video cassette recording format developed by Sony. It was one of the main competitors in the videotape format war against its primary rival, VHS. Betamax was introduced in Japan on May 10, 1975, and launched in the United States later that year. Betamax was widely regarded, in part due to Sony's marketing, as offering superior picture quality compared to VHS. Its initial β1 speed provided 250 horizontal lines of resolution, compared to VHS's 240 lines, but early Beta tapes were limited to 60 minutes of recording time, making them impractical for recording movies or sporting events. To address this, Sony introduced the β2 speed, which doubled recording time to two hours but reduced resolution, negating its technical advantage. VHS's commercial success over Betamax was also driven by JVC's strategy of licensing the format broadly, spurring competition ...

Random Access
Random access (also called direct access) is the ability to access an arbitrary element of a sequence in equal time or any datum from a population of addressable elements roughly as easily and efficiently as any other, no matter how many elements may be in the set. In computer science it is typically contrasted to sequential access which requires data to be retrieved in the order it was stored. For example, data might be stored notionally in a single sequence like a row, in two dimensions like rows and columns on a surface, or in multiple dimensions. However, given all the coordinates, a program can access each record about as quickly and easily as any other. In this sense, the choice of datum is arbitrary in the sense that no matter which item is sought, all that is needed to find it is its address, i.e. the coordinates at which it is located, such as its row and column (or its track and record number on a magnetic drum). At first, the term "random access" was used because th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Remote Control
A remote control, also known colloquially as a remote or clicker, is an consumer electronics, electronic device used to operate another device from a distance, usually wirelessly. In consumer electronics, a remote control can be used to operate devices such as a television set, DVD player or other digital home media appliance. A remote control can allow operation of devices that are out of convenient reach for direct operation of controls. They function best when used from a short distance. This is primarily a convenience feature for the user. In some cases, remote controls allow a person to operate a device that they otherwise would not be able to reach, as when a garage door opener is triggered from outside. Early television remote controls (1956–1977) used ultrasonics, ultrasonic tones. Present-day remote controls are commonly consumer IR, consumer infrared devices which send digitally-coded pulses of infrared radiation. They control functions such as power, volume, chan ...

Stereo Sound
Stereophonic sound, commonly shortened to stereo, is a method of sound reproduction that recreates a multi-directional, 3-dimensional audible perspective. This is usually achieved by using two independent audio channels through a configuration of two loudspeakers (or stereo headphones) in such a way as to create the impression of sound heard from various directions, as in natural hearing. Because the multi-dimensional perspective is the crucial aspect, the term ''stereophonic'' also applies to systems with more than two channels or speakers such as quadraphonic and surround sound. Binaural sound systems are also ''stereophonic''. Stereo sound has been in common use since the 1970s in entertainment media such as broadcast radio, recorded music, television, video cameras, cinema, computer audio, and the Internet. Etymology The word ''stereophonic'' derives from the Greek (''stereós'', "firm, solid") + (''phōnḗ'', "sound, tone, voice") and it was coined in 1927 by West ...

Race For Your Life, Charlie Brown
''Race for Your Life, Charlie Brown'' is a 1977 American animated adventure comedy film produced by United Feature Syndicate for Paramount Pictures, directed by Bill Melendez and Phil Roman, and the third in a series of films based on the ''Peanuts'' comic strip. It was the first ''Peanuts'' feature-length film produced after the death of composer Vince Guaraldi, who was originally intended to score the film, and used the same voice cast from the 1975 and 1976 TV specials, ''You're a Good Sport, Charlie Brown'', '' Happy Anniversary, Charlie Brown'', and ''It's Arbor Day, Charlie Brown'', and the same voice cast member from the 1974 TV special, ''It's a Mystery, Charlie Brown''. However, Liam Martin voiced Linus van Pelt for the last time in the movie, and went on to voice Charlie Brown in the 1978 TV special, '' What a Nightmare, Charlie Brown!''. This would be Stuart Brotman's final role before his death from a brain aneurysm in 2011. Unlike the previous two ''Peanuts'' theat ...

Locked Groove
The overwhelming majority of records manufactured have been of certain sizes (7, 10, or 12 inches), playback speeds (33, 45, or 78 RPM), and appearance (round black discs). However, since the commercial adoption of the gramophone record (called a phonograph record in the U.S., where both cylinder records and disc records were invented), a wide variety of records have also been produced that do not fall into these categories, and they have served a variety of purposes. Unusual sizes The most common diameter sizes for gramophone records are 12-inch, 10-inch, and 7-inch (, , and ). Early American shellac records were all 7-inch until 1901, when 10-inch records were introduced. 12-inch records joined them in 1903. By 1910, other sizes were retired and nearly all discs were either 10-inch or 12-inch, although both sizes were normally a bit smaller than their official diameter. In Europe, early 10-inch and 12-inch shellac records were produced in the first three decades of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polyvinyl Chloride
Polyvinyl chloride (alternatively: poly(vinyl chloride), colloquial: vinyl or polyvinyl; abbreviated: PVC) is the world's third-most widely produced synthetic polymer of plastic (after polyethylene and polypropylene). About 40 million tons of PVC are produced each year. PVC comes in rigid (sometimes abbreviated as RPVC) and flexible forms. Rigid PVC is used in construction for pipes, doors and windows. It is also used in making plastic bottles, packaging, and bank or membership cards. Adding plasticizers makes PVC softer and more flexible. It is used in plumbing, electrical cable insulation, flooring, signage, phonograph records, inflatable products, and in rubber substitutes. With cotton or linen, it is used in the production of canvas. Polyvinyl chloride is a white, brittle solid. It is soluble in ketones, chlorinated solvents, dimethylformamide, THF and DMAc. Discovery PVC was synthesized in 1872 by German chemist Eugen Baumann after extended investigation and experimenta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Get Smart
''Get Smart'' is an American comedy television series parodying the Spy fiction, secret agent genre that had become widely popular in the first half of the 1960s with the release of the ''James Bond'' films. It was created by Mel Brooks and Buck Henry, and had its television premiere on NBC on September 18, 1965. It starred Don Adams (who was also a director on the series) as agent Get Smart#Characters, Maxwell Smart (Agent 86), Barbara Feldon as Agent 99, and Edward Platt as The Chief. Henry said that they created the show at the request of Daniel Melnick to capitalize on James Bond (literary character), James Bond and Inspector Clouseau, "the two biggest things in the entertainment world today". Brooks described it as "an insane combination of James Bond and Mel Brooks comedy". The show generated a number of popular catchphrases during its run, including "sorry about that, Chief", "...and ''loving'' it", "missed it by ''that much''", and "would you believe...". The show was f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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. See also * Video High Density (JVC, 1970) * Electronic Video Recording (CBS, 1967) * Phonovision Phonovision was a patented concept to create pre-recorded mechanically scanned television recordings on gramophone records.

Phonograph Record
A phonograph record (also known as a gramophone record, especially in British English) or a vinyl record (for later varieties only) is an analog sound storage medium in the form of a flat disc with an inscribed, modulated spiral groove. The groove usually starts near the outside edge and ends near the center of the disc. The stored sound information is made audible by playing the record on a phonograph (or "gramophone", "turntable", or "record player"). Records have been produced in different formats with playing times ranging from a few minutes to around 30 minutes per side. For about half a century, the discs were commonly made from shellac and these records typically ran at a rotational speed of 78 rpm, giving it the nickname "78s" ("seventy-eights"). After the 1940s, "vinyl" records made from polyvinyl chloride (PVC) became standard replacing the old 78s and remain so to this day; they have since been produced in various sizes and speeds, most commonly 7-inch discs pla ...
