VCR
A videocassette recorder (VCR) or video recorder is an electromechanical device that records analog audio and analog video from broadcast television or other source on a removable, magnetic tape videocassette, and can play back the recording. Use of a VCR to record a television program to play back at a more convenient time is commonly referred to as ''timeshifting''. VCRs can also play back prerecorded tapes. In the 1980s and 1990s, prerecorded videotapes were widely available for purchase and rental, and blank tapes were sold to make recordings. VCRs declined in popularity during the early 2000s and in July 2016, Funai Electric, the last manufacturer of them ceased production. History Early machines and formats The history of the videocassette recorder follows the history of videotape recording in general. Ampex introduced the quadruplex videotape professional broadcast standard format with its Ampex VRX-1000 in 1956. It became the world's first commercially success ...

Video Cassette Recording
Video Cassette Recording (VCR) is an early domestic analog recording format designed by Philips. It was the first successful consumer-level home videocassette recorder (VCR) system. Later variants included the VCR-LP and Super Video (SVR) formats. The VCR format was introduced in 1972, just after the Sony U-matic format in 1971. Although at first glance the two might appear to have been competing formats, they were aimed at very different markets. After failing as a consumer format, U-matic was marketed as a professional television production format, whilst VCR was targeted particularly at educational but also domestic users. Unlike some other early formats such as Cartrivision, the VCR format does record a high-quality video signal without resorting to Skip field. Home video systems had previously been available, but they were open-reel systems (such as the Sony CV-2000) and were expensive to both buy and operate. They were also unreliable and often only recorded in black an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
U-matic
U-matic is an analogue recording videocassette format first shown by Sony in prototype in October 1969, and introduced to the market in September 1971. It was among the first video formats to contain the videotape inside a cassette, as opposed to the various reel-to-reel or open-reel formats of the time. The videotape is wide, so the format is often known as "three-quarter-inch" or simply "three-quarter", compared to open reel videotape formats in use, such as type C videotape and quadruplex videotape. Unlike most other cassette-based tape formats, the supply and take-up reels in the cassette turn in opposite directions during playback, fast-forward, and rewind: one reel would run clockwise while the other would run counter-clockwise. A locking mechanism integral to each cassette case secures the tape hubs during transportation to keep the tape wound tightly on the hubs. Once the cassette is taken off the case, the hubs are free to spin. A spring-loaded tape cover door ... [...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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Videotape Recorder
A video tape recorder (VTR) is a tape recorder designed to record and playback video and audio material from magnetic tape. The early VTRs were open-reel devices that record on individual reels of 2-inch-wide (5.08 cm) tape. They were used in television studios, serving as a replacement for motion picture film stock and making recording for television applications cheaper and quicker. Beginning in 1963, videotape machines made instant replay during televised sporting events possible. Improved formats, in which the tape was contained inside a videocassette, were introduced around 1969; the machines which play them are called videocassette recorders. An agreement by Japanese manufacturers on a common standard recording format, which allowed cassettes recorded on one manufacturer's machine to play on another's, made a consumer market possible; and the first consumer videocassette recorder, which used the U-matic format, was introduced by Sony in 1971.

Analog Video
Video is an electronic medium for the recording, copying Copying is the duplication of information or an artifact based on an instance of that information or artifact, and not using the process that originally generated it. With analog forms of information, copying is only possible to a limited degree ..., playback, broadcasting, and display of moving picture, moving image, visual Media (communication), media. Video was first developed for mechanical television systems, which were quickly replaced by cathode-ray tube (CRT) systems which, in turn, were replaced by flat panel displays of several types. Video systems vary in display resolution, Display aspect ratio, aspect ratio, refresh rate, color capabilities and other qualities. Analog and digital variants exist and can be carried on a variety of media, including radio broadcast, magnetic tape, optical discs, Video file format, computer files, and Streaming media, network streaming.

Timeshifting
In broadcasting, time shifting is the recording of programming to a storage medium to be viewed or listened to after the live broadcasting. Typically, this refers to TV programming but it can also refer to radio shows via podcasts. In recent years, the advent of the digital video recorder (DVR) has made time shifting easier, by using an electronic program guide (EPG) and recording shows onto a hard disk. Some DVRs have other possible time-shifting methods, such as being able to start watching the recorded show from the beginning even if the recording is not yet complete. In the past, time shifting was done with a video cassette recorder (VCR) and its timer function, in which the VCR tunes into the appropriate station and records the show onto video tape. Certain broadcasters transmit timeshifted versions of their channels, usually carrying programming from one hour in the past, to enable those without recording abilities to resolve conflicts and those with recording abilities mor ...

CV-2000
CV-2000 was one of the world's first home video tape recorders (VTR), introduced by Sony in August, 1965. The 'CV' in the model name stood for 'Consumer Video'. This was Sony's domestic format throughout the 1960s. It was the first fully transistorized VCR. The CV-2000 was developed by Sony engineer Nobutoshi Kihara. On its release, the CV-2000D machine was listed for US$695 (while a portable version in a more durable case, the CV-2000, was listed for $730). It used video tape in a reel-to-reel format, meaning the tape had to be manually threaded around the helical scan video head drum. The CV-2000 was one-tenth the weight and price of other analog video recording products of its era. It recorded television programs in black and white Black-and-white (B&W or B/W) images combine black and white in a continuous spectrum, producing a range of shades of grey. Media The history of various visual media began with black and white, and as technology improved, altered to co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quadruplex Videotape
2-inch quadruplex videotape (also called 2″ quad video tape or quadraplex) was the first practical and commercially successful analog recording video tape format. It was developed and released for the broadcast television industry in 1956 by Ampex, an American company based in Redwood City, California. The first videotape recorder using this format was built in the same year. This format revolutionized broadcast television operations and television production, since the only recording medium available to the TV industry until then was film used for kinescopes. Since most United States West Coast network broadcast delays done by the television networks at the time were done with film kinescopes that needed time for developing, the networks wanted a more practical, cost-effective, and quicker way to time-shift television programming for later airing on the West Coast than the expense and time consumption of the processing and editing of film caused. Faced with these challenges ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
