Video8
The 8mm video format refers informally to three related 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, 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 Japan introduced the Handycam, one of the first Video8 cam ...

Digital8
Digital8 (or D8) is a consumer digital recording videocassette for camcorders developed by Sony, and introduced in 1999. The Digital8 format is a combination of the earlier analog Hi8 tape transport with the digital DV codec. Digital8 equipment uses the same videocassettes as analog recording Hi8 equipment, but the signal is encoded ''digitally'' using the industry-standard DV codec, which means it has identical digital audio and digital video specifications compared with DV. To facilitate digital recording on existing Hi8 video cassettes the helical scan video head drum spins 2.5× faster. For both NTSC and PAL Digital8 equipment, a standard-length 120-minute NTSC/90-minute PAL Hi8 magnetic tape cassette will store 60 minutes of Digital8 video (Standard Play) or 90 minutes (Long Play). There are 90-minute versions marketed specifically for Digital8, but these use thinner tape than the 60-minute ones. LP is model specific, such as the TRV-30, TRV-40, and others. Digital8 re ...

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 ...

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 ...

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 ...

Videotape
Videotape is magnetic tape used for storing video and usually Sound recording and reproduction, sound in addition. Information stored can be in the form of either an analog signal, analog or Digital signal (signal processing), 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 (signal processing), bandwidth, and Tape head, stationary heads would require extremely high tape speeds, in most cases, a helical scan, helical-scan video head rotates against the moving tape to record the data in two dimensions. Tape is a Linear motion, 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-q ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Data8
The 8 mm backup format is a discontinued magnetic tape data storage format used in computer systems, pioneered by Exabyte Corporation. It is also known as Data8, often abbreviated to D8 and is written as D-Eight on some Sony branded media. Such systems can back up up to 60 GB of data depending on configuration. The cassettes have the same dimensions and construction as the cassettes used in 8 mm video format recorders and camcorders. Until the advent of Advanced Intelligent Tape, AIT, Exabyte was the sole vendor of 8 mm format tape drives. The company was formed with the aim of taking the 8 mm video format and making it suitable for data storage. They did so by building a reliable mechanism and data format that used the common 8 mm helical scan videotape technology that was available then. Exabyte's first 8 mm tape drive was made available in 1987. This was followed up with their Mammoth tape drive in 1996, and the Mammoth-2 (M2) in 1999. Exaby ...

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.
