PortaPak
A Portapak is a battery-powered, self-contained video tape analog recording system. Introduced to the market in 1967, it could be carried and operated by one person. Earlier television cameras were large and heavy, required a specialized vehicle for transportation, and were mounted on a pedestal. The Portapak made it possible to shoot and record video easily outside of the studio without requiring a crew. Although it recorded at a lower quality than television studio cameras, the Portapak was adopted by both professionals and amateurs as a new method of video recording. Before Portapak cameras, remote television news footage was routinely photographed on 16mm film and telecined for broadcast. The first portapak system, the Sony DV-2400 Video Rover, was a two-piece set consisting of a black-and-white composite video video camera and a separate record-only helical scan ½″ video tape recorder (VTR) unit. It required a Sony CV series VTR (such as the CV-2000) to play back the vi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Video Art
Video art is an art form which relies on using video technology as a visual and audio medium. Video art emerged during the late 1960s as new consumer video technology such as video tape recorders became available outside corporate broadcasting. Video art can take many forms: recordings that are broadcast; installations viewed in galleries or museums; works streamed online, distributed as video tapes, or DVDs; and performances which may incorporate one or more television sets, video monitors, and projections, displaying live or recorded images and sounds. Video art is named for the original analog video tape, which was the most commonly used recording technology in much of the form history into the 1990s. With the advent of digital recording equipment, many artists began to explore digital technology as a new way of expression. One of the key differences between video art and theatrical cinema is that video art does not necessarily rely on many of the conventions that define t ...

EIAJ-1
EIAJ-1 was a standard for video tape recorders (VTRs) developed by the Electronic Industries Association of Japan with the cooperation and assistance of several Japanese electronics manufacturers in 1969. It was the first standardized format for industrial/non-broadcast VTRs using a helical scan system employing open reel tape. Previously, each manufacturer of machines in this market used a different proprietary format, with differing tape speeds, scanner drum diameters, bias frequencies, tracking head placement, and so on, although most used 1/2" wide tape. As a result, video tapes recorded on one make and/or model of VTR could only be interchanged with other machines using that specific format, hampering compatibility. For example, a reel of tape recorded on a Panasonic machine would not play on a Sony machine, and vice versa. The EIAJ-1 standard ended this incompatibility, giving those manufacturers a standardized format, interchangeable with almost all VTRs subsequently b ...

Videofreex
The Videofreex were a pioneering video collective who used the Sony Portapak for countercultural video projects from 1969 to 1978. They were founded in 1969 by David Cort, Mary Curtis Ratcliff and Parry Teasdale, after Cort and Teasdale met each other at the Woodstock Music Festival. They were based out of a 17 bedroom house in the Catskill Mountains named the Maple Tree Farm. In order to receive an initial grant of $40,000 from The New York State Council of the Arts, the Videofreex rebranded itself as the non-profit "Media Bus". Michael Shamberg, author of '' Guerrilla Television'' and founding member of TVTV, remarked, "The Freex are the most production oriented of the video groups €¦in terms of finished, cleanly edited, high quality tape, which is generally quite entertaining, the Videofreex are clearly the best." Mirroring the beliefs outlined in ''Guerrilla Television'', they believed they could turn the medium of television, at the time dominated by The "Big Three" Televis ...

Video Camera
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] |

History Of Television
The concept of television was the work of many individuals in the late 19th and early 20th centuries. The first practical transmissions of moving images over a radio system used mechanical rotating perforated disks to scan a scene into a time-varying signal that could be reconstructed at a receiver back into an approximation of the original image. Development of television was interrupted by the Second World War. After the end of the war, all-electronic methods of scanning and displaying images became standard. Several different standards for addition of color to transmitted images were developed with different regions using technically incompatible signal standards. Television broadcasting expanded rapidly after World War II, becoming an important mass media, mass medium for advertising, propaganda, and entertainment. Television broadcasts can be distributed over the air by VHF and UHF radio signals from terrestrial transmitting stations, by microwave signals from Earth orbi ...

Raindance Foundation
Raindance Foundation (RainDance Corporation) was founded in October 1969 by Frank Gillette, Paul Ryan, Michael Shamberg, Louis Jaffe, and Marco Vassi. Raindance was a self-described "alternate culture think-tank" that embraced video as an alternative form of cultural communication. The name "RainDance Corporation" was an ironic reference to the mainstream organization Rand Corporation. Influenced by the communications theories of Marshall McLuhan and Buckminster Fuller, the collective produced a data bank of tapes and writings that explored the relation of cybernetics, media, and ecology. From 1970 to 1974, Raindance published the seminal video journal ''Radical Software'' (initially edited by Beryl Korot and Phyllis Gershuny), which provided a network of communications for the emerging alternative video movement with a circulation of 5,000. In 1971, Dean and Dudley Evenson joined the Raindance Foundation and taught video workshops through the Metropolitan Museum of Art under a g ...

Big Three Television Networks
In the United States, there are three major traditional commercial broadcast television networks — CBS (Columbia Broadcasting System), NBC (National Broadcasting Company), and ABC (American Broadcasting Company) — that due to their longevity and ratings success are referred to as the "Big Three." They dominated American television until the 1990s and are still considered major U.S. broadcast companies. Backgrounds The National Broadcasting Company and Columbia Broadcasting System were both founded as radio networks in the 1920s, with NBC eventually encompassing two national radio networks, the prestige Red Network and the lower-profile Blue Network. They gradually began experimental television stations in the 1930s, with commercial broadcasts being allowed by the Federal Communications Commission on July 1, 1941. In 1943, the U.S. government determined that NBC's two-network setup was anticompetitive and forced it to spin off one of the networks; NBC chose to sell th ...
