8 Mm Video Format
The 8mm video format refers informally to three related Videotape#Consumer and "prosumer" camcorders, videocassette formats. These are the original Video8 format (analog video and analog audio but with provision for digital audio), its improved variant Hi8, as well as a more recent digital recording format Digital8. Their user base consisted mainly of amateur camcorder users, although they also saw important use in the professional television production field. In 1982, five companies – Sony, Panasonic, Matsushita (now Panasonic), JVC, Hitachi, and Philips – created a preliminary draft of the unified format and invited members of the Electronic Industries Association of Japan, the Magnetic Tape Industry Association, the Japan Camera Industry Association and other related associations to participate. As a result, a consortium of 127 companies endorsed 8-mm video format in April 1984. In January 1984, Eastman Kodak announced the new technology in the U.S. In 1985, Sony of Jap ...

Video is an Electronics, electronic medium for the recording, copying, 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 broadcasts, magnetic tape, optical discs, Video file format, computer files, and Streaming media, network streaming. Etymology The word ''video'' comes from the Latin verb ''video,'' meaning to see or ''videre''. And as a noun, "that which is displayed on a (television) screen," History Analog video Video developed from facsimile systems developed in the mid-19th century. Early mecha ...

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 the 2000s, digital recording became the norm, and additionally tape was replaced by storage media such as mini- HDD, MiniDVD, 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 protract ...

MiniDVD
MiniDVD or 8 cm DVD (also "3 inch DVD") is a DVD disc with a reduced diameter of . It has been most commonly used in camcorders due to its compact size. The most common MiniDVDs are single layered and hold 1.4 GB of data, but there are variants that can offer up to 5.2 GB of storage space, through a combination of dual layers and dual sides. 8 cm DVDs were originally used for music videos and as such became known as DVD single, similarly to how 8 cm optical discs were previously used for music singles on compact discs (i.e. CD single and miniCD). However the MiniDVD format has been mostly used as recordable discs in DVD-based camcorders during the 2000s; a single layer disc can record up to 30 minutes of standard definition video. A number of movies and TV shows have also been released on the format in the mid-2000s, usually targeting children using low-cost small players. Nintendo used a very similar disc-based format for the GameCube. MiniDVD capacities ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MiniDV
DV (from ''Digital Video'') is a family of codecs and Videotape, tape formats used for storing digital video, launched in 1995 by a consortium of camcorder, video camera manufacturers led by Sony and Panasonic. It includes the recording or cassette formats DV, MiniDV, HDV, DVCAM, DVCPro, DVCPro50, DVCProHD, Digital8, and Digital-S. DV has been used primarily for video recording with camcorders in the amateur and professional sectors. DV was designed to be a standard for home video using digital data instead of Analog video, analog. Compared to the analog 8 mm video format, Video8/Hi8, VHS-C and VHS formats, DV features a higher video resolution (on par with professional-grade Digital Betacam); it records uncompressed 16-bit Pulse-code modulation, PCM audio like Compact Disc Digital Audio, CD. The most popular tape format using a DV codec was MiniDV; these cassettes measured just 6.35 mm/¼ inch, making it ideal for video cameras and rendering older analog formats obsolete. In the ...

Digital Video
Digital video is an electronic representation of moving visual images (video) in the form of encoded digital data. This is in contrast to analog video, which represents moving visual images in the form of analog signals. Digital video comprises a series of digital images displayed in rapid succession, usually at 24, 30, or 60 frames per second. Digital video has many advantages such as easy copying, multicasting, sharing and storage. Digital video was first introduced commercially in 1986 with the D1 (Sony), Sony D1 format, which recorded an uncompressed standard-definition component video signal in digital form. In addition to uncompressed formats, popular Data compression, compressed digital video formats today include H.264 and MPEG-4. Modern interconnect standards used for playback of digital video include HDMI, DisplayPort, Digital Visual Interface (DVI) and serial digital interface (SDI). Digital video can be copied and reproduced with no degradation in quality. In contra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Frequency Modulation
Frequency modulation (FM) is a signal modulation technique used in electronic communication, originally for transmitting messages with a radio wave. In frequency modulation a carrier wave is varied in its instantaneous frequency in proportion to a property, primarily the instantaneous amplitude, of a message signal, such as an audio signal. The technology is used in telecommunications, radio broadcasting, signal processing, and Run-length limited#FM: .280.2C1.29 RLL, computing. In Analog signal, analog frequency modulation, such as radio broadcasting of voice and music, the instantaneous frequency deviation, i.e. the difference between the frequency of the carrier and its center frequency, has a functional relation to the modulating signal amplitude. Digital data can be encoded and transmitted with a type of frequency modulation known as frequency-shift keying (FSK), in which the instantaneous frequency of the carrier is shifted among a set of frequencies. The frequencies m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Handycam
Handycam is a line of camcorders made by Sony and introduced in 1985. Handycam was first used as the name of the first Video8 camcorder in 1985, replacing Sony's previous line of Betamovie, Betamax-based models of camcorders. The name was intended to emphasize the "handy" palm size nature of the camera, made possible by the then-new miniaturized tape format. This was in contrast to the larger, shoulder mounted cameras made before the creation of Video8, as well as competing smaller formats such as VHS-C. Formats Sony has continued to produce Handycams in a variety of guises ever since, developing the Video8 format to produce Hi8 (equivalent to S-VHS quality) and later Digital8, using the same basic format to record digital video. The Handycam label continues to be applied as recording formats evolve, such as adopting the MiniDV, MiniDVD, and MicroMV formats, and then later using hard disk drives and flash memory.

Philips
Koninklijke Philips N.V. (), simply branded Philips, is a Dutch multinational health technology company that was founded in Eindhoven in 1891. Since 1997, its world headquarters have been situated in Amsterdam, though the Benelux headquarters is still in Eindhoven. The company gained its royal honorary title in 1998. Philips was founded by Gerard Philips and his father Frederik, with their first products being light bulbs. Through the 20th century, it grew into one of the world's largest electronics conglomerates, with global market dominance in products ranging from kitchen appliances and electric shavers to light bulbs, televisions, cassettes, and compact discs (both of which were invented by Philips). At one point, it played a dominant role in the entertainment industry (through PolyGram). However, intense competition from primarily East Asian competitors throughout the 1990s and 2000s led to a period of downsizing, including the divestment of its lighting and c ...
