Betamovie
Betamovie is the brand name for a range of consumer grade camcorders developed by Sony for the Betamax format. By "camcorder" is understood a single unit comprising a video camera and a video recorder. Betamovie records analog video on a standard Betamax cassette. A range of models was manufactured for the PAL and NTSC formats. The first model, BMC-100P (PAL) and BMC-110 (NTSC) was released in 1983 making it the first commercial consumer grade camcorder. While only standard beta units were available in PAL, several SuperBeta models were produced for the NTSC format. Due to constructional limitations, the Betamovie has no playback function. It is only capable of recording. This limitation, along with the decline of the Betamax format in the late 1980s, caused Sony to abandon the Betamovie line just a few years after its initial release in favor of its newly developed Video8 format. History As far back as the 1960s, cameras were available for the reel-to-reel portable VTRs of that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Betamax
Betamax (also known as Beta, as in its logo) is a consumer-level analog recording and cassette format of magnetic tape for video, commonly known as a video cassette recorder. It was developed by Sony and was released in Japan on May 10, 1975, followed by the US in November of the same year. Betamax is widely considered to be obsolete, having lost the videotape format war which saw its closest rival, VHS, dominate most markets. Despite this, Betamax recorders continued to be manufactured and sold until August 2002, when Sony announced that they were discontinuing production of all remaining Betamax models. Sony continued to sell Betamax cassettes until March 2016. Original version Launch and early models The first Betamax device introduced in the United States was the LV-1901 console, which included a color monitor, and appeared in stores in early November 1975. The cassettes contain videotape in a design similar to that of the earlier, professional , U-matic format. L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Camcorder
A camcorder is a self-contained portable electronic device with video and recording as its primary function. It is typically equipped with an articulating screen mounted on the left side, a belt to facilitate holding on the right side, hot-swappable battery facing towards the user, hot-swappable recording media, and an internally contained quiet optical zoom lens. The earliest camcorders were tape-based, recording analog signals onto videotape cassettes. In 2006, digital recording became the norm, with tape replaced by storage media such as mini-HD, microDVD, internal flash memory and SD cards. More recent devices capable of recording video are camera phones and digital cameras primarily intended for still pictures, whereas dedicated camcorders are often equipped with more functions and interfaces than more common cameras, such as an internal optical zoom lens that is able to operate silently with no throttled speed, whereas cameras with protracting zoom lenses commonly thro ...

JVC GR-C1
The JVC GR-C1 was a camcorder released in March 1984 by JVC and was notable as the first all-in-one VHS-C camcorder, as opposed to earlier portable systems in which the camera and recorder were separate units linked by a cable. It used a 30-minute VHS-C video tape, which could be played back in a standard VHS VCR using an adapter. The camera was also capable of playback in the viewfinder or through a composite video cable. A separate RF modulator was available to enable connection to the aerial socket of domestic televisions. By comparison, the camera's nearest competitor at the time, Sony's Betamovie, could record but not play back. JVC invented the VHS format and released the first VCR of that type, the JVC HR-3300, in 1976. Unlike later CCD-based camcorders, the GR-C1 uses a 1/2" Saticon pickup tube. It was also released under license and in a black finish by German company Telefunken as the 890 Movie and in a dark red by German company SABA as the VM 6700. The GR-C1 wa ...

Betacam
Betacam is a family of half-inch professional videocassette products developed by Sony in 1982. In colloquial use, "Betacam" singly is often used to refer to a Betacam camcorder, a Betacam tape, a Betacam video recorder or the format itself. All Betacam variants from (plain) analog recording Betacam to Betacam SP and digital recording Digital Betacam (and additionally, HDCAM and HDCAM SR), use the same shape videocassettes, meaning vaults and other storage facilities do not have to be changed when upgrading to a new format. The cassettes are available in two sizes: S (for Short) and L (for Long). The Betacam camcorder can only load S magnetic tapes, while television studio sized video tape recorders (VTR) designed for video editing can play both S and L tapes. The cassette shell and case for each Betacam cassette is colored differently depending on the format, allowing for easy visual identification. There is also a mechanical key that allows a video tape recorder to identify whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Video Camera Tube
Video camera tubes were devices based on the cathode ray tube that were used in television cameras to capture television images, prior to the introduction of charge-coupled device (CCD) image sensors in the 1980s. Several different types of tubes were in use from the early 1930s, and as late as the 1990s. In these tubes, an electron beam was scanned across an image of the scene to be broadcast focused on a target. This generated a current that was dependent on the brightness of the image on the target at the scan point. The size of the striking ray was tiny compared to the size of the target, allowing 483 horizontal scan lines per image in the NTSC format, 576 lines in PAL, and as many as 1035 lines in Hi-Vision. Cathode ray tube Any vacuum tube which operates using a focused beam of electrons, originally called cathode rays, is known as a cathode ray tube (CRT). These are usually seen as display devices as used in older (i.e., non-flat panel) television receivers and computer d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ampere
The ampere (, ; symbol: A), often shortened to amp,SI supports only the use of symbols and deprecates the use of abbreviations for units. is the unit of electric current in the International System of Units (SI). One ampere is equal to electrons worth of charge moving past a point in a second. It is named after French mathematician and physicist André-Marie Ampère (1775–1836), considered the father of electromagnetism along with Danish physicist Hans Christian Ørsted. As of the 2019 redefinition of the SI base units, the ampere is defined by fixing the elementary charge to be exactly C ( coulomb), which means an ampere is an electrical current equivalent to elementary charges moving every seconds or elementary charges moving in a second. Prior to the redefinition the ampere was defined as the current that would need to be passed through 2 parallel wires 1 metre apart to produce a magnetic force of newtons per metre. The earlier CGS system had two definitio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Videocamera A Batteria, Betamax, Portatile - Museo Scienza Tecnologia Milano 09695 06
A video camera is an optical instrument that captures videos (as opposed to a movie camera, which records images on film). Video cameras were initially developed for the television industry but have since become widely used for a variety of other purposes. Video cameras are used primarily in two modes. The first, characteristic of much early broadcasting, is live television, where the camera feeds real time images directly to a screen for immediate observation. A few cameras still serve live television production, but most live connections are for security, military/tactical, and industrial operations where surreptitious or remote viewing is required. In the second mode the images are recorded to a storage device for archiving or further processing; for many years, videotape was the primary format used for this purpose, but was gradually supplanted by optical disc, hard disk, and then flash memory. Recorded video is used in television production, and more often surveillance and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nickel–cadmium Battery
The nickel–cadmium battery (Ni–Cd battery or NiCad battery) is a type of rechargeable battery using nickel oxide hydroxide and metallic cadmium as electrodes. The abbreviation ''Ni-Cd'' is derived from the chemical symbols of nickel (Ni) and cadmium (Cd): the abbreviation ''NiCad'' is a registered trademark of SAFT Corporation, although this brand name is commonly used to describe all Ni–Cd batteries. Wet-cell nickel-cadmium batteries were invented in 1899. A Ni-Cd battery has a terminal voltage during discharge of around 1.2 volts which decreases little until nearly the end of discharge. The maximum electromotive force offered by a Ni-Cd cell is 1.3V. Ni-Cd batteries are made in a wide range of sizes and capacities, from portable sealed types interchangeable with carbon-zinc dry cells, to large ventilated cells used for standby power and motive power. Compared with other types of rechargeable cells they offer good cycle life and performance at low temperatures with a fai ...

VHS-C
VHS-C is the compact VHS videocassette format, introduced by Victor Company of Japan (JVC) in 1982, and used primarily for consumer-grade compact analog recording camcorders. The format is based on the same video tape as is used in VHS, and can be played back in a standard VHS VCR with an adapter. Though quite inexpensive, the format is largely obsolete even as a consumer standard and has been replaced in the marketplace by digital video formats, which have smaller form factors. The magnetic tape on VHS-C cassettes is wound on one main spool and used a gear wheel which moves the tape forward. It can also be moved by hand. This development hampered the sales of the Betamax system somewhat, because the Betamax cassette geometry prevented a similar development. VHS-C cassette was larger than Video8 cassette, but was compatible with VHS tape recorders, using a special adapter cassette. The adapter contains a standard full-size engagement hub for the VCR's takeup sprocket, which co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
