Desktop Video
Desktop video refers to a phenomenon lasting from the mid-1980s to the early 1990s when the graphics capabilities of personal computers such as Commodore's Amiga, the Apple Macintosh II and specially-upgraded IBM PC compatibles had advanced to the point where individuals and local broadcasters could use them for analog non-linear editing (NLE) and vision mixing in video production. Despite the use of computers, desktop video should not be confused with digital video since the video data remained analog. Full-screen, full-motion video's vast storage requirements meant that the promise of digital encoding would not be realized on desktop computers for at least another decade. Description There were multiple models of genlock cards available to synchronise the content; the Newtek Video Toaster was commonly used in Amiga and PC systems, while Mac systems had the SuperMac Video Spigot and Radius VideoVision cards. Apple later introduced the Macintosh Quadra 840AV and Centris 660AV sy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Video Spigot
Video is an electronic medium for the recording, copying, playback, broadcasting, and display of moving visual 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, 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 broadcast, magnetic tape, optical discs, computer files, and network streaming. History Analog video Video technology was first developed for mechanical television systems, which were quickly replaced by cathode-ray tube (CRT) television systems, but several new technologies for video display devices have since been invented. Video was originally exclusively a live technology. Charles Ginsburg led an Ampex research team developing one of the first practica ...

Film And Video Terminology
A film also called a movie, motion picture, moving picture, picture, photoplay or (slang) flick is a work of visual art that simulates experiences and otherwise communicates ideas, stories, perceptions, feelings, beauty, or atmosphere through the use of moving images. These images are generally accompanied by sound and, more rarely, other sensory stimulations. The word "cinema", short for cinematography, is often used to refer to filmmaking and the film industry, and to the art form that is the result of it. Recording and transmission of film The moving images of a film are created by photographing actual scenes with a motion-picture camera, by photographing drawings or miniature models using traditional animation techniques, by means of CGI and computer animation, or by a combination of some or all of these techniques, and other visual effects. Before the introduction of digital production, series of still images were recorded on a strip of chemically sensitize ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Home Video
Home video is prerecorded media sold or rented for home viewing. The term originates from the VHS and Betamax era, when the predominant medium was videotapes, but has carried over to optical disc formats such as DVD, Blu-ray and streaming media. In a different usage, "home video" refers to amateur video recordings, also known as home movies. The home-video business distributes films, television series, telefilms and other audiovisual media in the form of videos in various formats to the public. These are either bought or rented, and then watched privately in purchasers' homes. Most theatrically released films are now released on digital media, both optical and download-based, replacing the largely obsolete videotape medium. the Video CD format remained popular in Asia. DVDs are gradually losing popularity since the late 2010s and early 2020s, when streaming media became mainstream. History As early as 1906, various film entrepreneurs began to discuss the potential of home ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Broadcasting
Broadcasting is the distribution (business), distribution of sound, audio or video content to a dispersed audience via any electronic medium (communication), mass communications medium, but typically one using the electromagnetic spectrum (radio waves), in a :wikt:one-to-many, one-to-many model. Broadcasting began with AM radio, which came into popular use around 1920 with the spread of vacuum tube radio transmitters and radio receiver, receivers. Before this, all forms of electronic communication (early radio, telephone, and telegraph) were wikt:one-to-one, one-to-one, with the message intended for a single recipient. The term ''broadcasting'' evolved from its use as the agricultural method of sowing seeds in a field by casting them broadly about. It was later adopted for describing the widespread distribution of information by printed materials or by telegraph. Examples applying it to "one-to-many" radio transmissions of an individual station to multiple listeners appeared as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Television Advertising
A television advertisement (also called a television commercial, TV commercial, commercial, spot, television spot, TV spot, advert, television advert, TV advert, television ad, TV ad or simply an ad) is a span of television programming produced and paid for by an organization. It conveys a message promoting, and aiming to market, a product, service or idea. Advertisers and marketers may refer to television commercials as TVCs. Advertising revenue provides a significant portion of the funding for most privately-owned television networks. During the 2010s, the number of commercials has grown steadily, though the length of each commercial has diminished. Advertisements of this type have promoted a wide variety of goods, services, and ideas ever since the early days of the history of television. The viewership of television programming, as measured by companies such as Nielsen Media Research in the United States, or BARB in the UK, is often used as a metric for television advertise ...

Public-access Television
Public-access television is traditionally a form of non-commercial mass media where the general public can create content television programming which is narrowcast through cable television specialty channels. Public-access television was created in the United States between 1969 and 1971 by the Federal Communications Commission (FCC), under Chairman Dean Burch, based on pioneering work and advocacy of George Stoney, Red Burns (Alternate Media Center), and Sidney Dean (City Club of NY). Public-access television is often grouped with public, educational, and government access television channels, under the acronym PEG. In 2020, the Alliance for Community Media published a directory listing over 1600 organizations operating these channels in the United States. Distinction from PBS In the United States, the Public Broadcasting Service (PBS) produces public television, offering an educational television broadcasting service of professionally produced, highly curated content.

Desktop Publishing
Desktop publishing (DTP) is the creation of documents using page layout software on a personal ("desktop") computer. It was first used almost exclusively for print publications, but now it also assists in the creation of various forms of online content. Desktop publishing software can generate layouts and produce typographic-quality text and images comparable to traditional typography and printing. Desktop publishing is also the main reference for digital typography. This technology allows individuals, businesses, and other organizations to self-publish a wide variety of content, from menus to magazines to books, without the expense of commercial printing. Desktop publishing often requires the use of a personal computer and WYSIWYG page layout software to create documents for either large-scale publishing or small-scale local multifunction peripheral output and distribution – although a non-WYSIWYG system such as LaTeX could also be used for the creation of highly structured a ...

SuperMac
The SuperMac was a line of Macintosh clones produced by UMAX Technologies from 1996 to 1998. Their models included the SuperMac S900/S910, J700, C500 and C500e/i/LT, C600e/v/LT/x and Aegis 200. The C500 was marketed as the Apus 2000 in Europe. They used versions of Apple's motherboard like Tsunami, Alchemy, and Tanzania, which were designed to use standard IBM PC compatible components in addition to Apple-proprietary components then in common use in the Power Macintosh family. The machines were popular in places like Asia, Europe, and North America due to their low price and reliability. After Steve Jobs returned to Apple as the new CEO, he revoked all of the clone producers' licenses to produce Mac clones except for UMAX, due to their sub-US$1,000 low-end offerings, a market in which Apple was not strong, and UMAX's stated desire to expand the Macintosh platform's presence in East Asian markets. UMAX was the only Macintosh clone manufacturer to get a license for Mac OS 8, which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
