Videocassettes And VCRs At Internet Archive.jpg
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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jack Mullin
John Thomas Mullin (October 5, 1913 – June 24, 1999) was an American pioneer in the field of magnetic tape sound recording and made significant contributions to many other related fields. From his days at Santa Clara University to his death, he displayed a deep appreciation for classical music and an aptitude for electronics and engineering. When he died in 1999, he was buried with a rosary and a reel of magnetic tape. A 2006 documentary movie, ''Sound Man: WWII to MP3'', was made about his life and contributions to sound recording. Work with the Signal Corps By 1943, German engineers had developed a high-quality form of magnetic tape sound recording that was unknown elsewhere. The Nazi radio networks used it to broadcast music and propaganda around the clock. From their monitoring of Nazi radio broadcasts during World War II, the Allies knew that German radio studios had some new kind of recorder that could reproduce high-fidelity sound in segments of unheard-of length, up ...

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] |
Longitudinal Video Recording
Longitudinal Video Recording or LVR was a consumer VCR system and videotape standard. Comparison with other VCR technologies LVR differed from other VCR technologies in that instead of running a tape slowly past a pair of rapidly moving recording heads and laying the tracks obliquely across the tape in a helical scan, the LVR ran a tape quickly past a stationary recording head which would step across the tape width and lay down a series of parallel tracks along the tape's length. The head used fixed scanning but moved down the tape to the next track once the end of the quickly moving tape (240 ips with 300 tracks to a ½” tape) had been reached. Development Work had begun on longitudinal video recording as early as 1950 by the electronics division of entertainer Bing Crosby's production company, Bing Crosby Enterprises (BCE), who had pioneered the use of magnetic tape recording for his radio show in the 1940s. BCE gave the world's first demonstration of a videotape recording in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Live Television
Live television is a television production broadcast in real-time, as events happen, in the present. In a secondary meaning, it may refer to streaming television over the Internet when content or programming is played continuously (not on demand). For example, the Pluto TV app has two categories for viewing: "Live TV" & "On Demand." On its website, Xfinity states "Watch TV series and top rated movies live and on demand with Xfinity Stream." In most cases live programming is not being recorded as it is shown on TV, but rather was not rehearsed or edited and is being shown only as it was recorded prior to being aired. Shows broadcast live include newscasts, morning shows, awards shows, sports programs, reality programs and, occasionally, episodes of scripted television series. Live television was more common until the late 1950s, when videotape technology was invented. Because of the prohibitive cost, adoption was slow, and some television shows remained live until the 197 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Television Program
Television, sometimes shortened to TV, is a telecommunication medium for transmitting moving images and sound. The term can refer to a television set, or the medium of television transmission. Television is a mass medium for advertising, entertainment, news, and sports. Television became available in crude experimental forms in the late 1920s, but only after several years of further development was the new technology marketed to consumers. After World War II, an improved form of black-and-white television broadcasting became popular in the United Kingdom and the United States, and television sets became commonplace in homes, businesses, and institutions. During the 1950s, television was the primary medium for influencing public opinion.Diggs-Brown, Barbara (2011''Strategic Public Relations: Audience Focused Practice''p. 48 In the mid-1960s, color broadcasting was introduced in the U.S. and most other developed countries. The availability of various types of archival stora ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Color Television
Color television or Colour television is a television transmission technology that includes color information for the picture, so the video image can be displayed in color on the television set. It improves on the monochrome or black-and-white television technology, which displays the image in shades of gray ( grayscale). Television broadcasting stations and networks in most parts of the world upgraded from black-and-white to color transmission between the 1960s and the 1980s. The invention of color television standards was an important part of the history and technology of television. Transmission of color images using mechanical scanners had been conceived as early as the 1880s. A demonstration of mechanically scanned color television was given by John Logie Baird in 1928, but its limitations were apparent even then. Development of electronic scanning and display made a practical system possible. Monochrome transmission standards were developed prior to World War II, but civ ...
