Apple AudioVision 14 Display
The Apple AudioVision 14 Display is a 14-inch Trinitron display that was manufactured by Apple Inc. This display is unique since it is the only display ever to use the HDI-45 connector, capable of transferring video to the screen, video capture ''input'' from an S-Video source, audio output, audio input, and Apple Desktop Bus (ADB) all through one cable. The monitor also has a built-in microphone. The included driver adds the following specialized functionality to the Sound control panel: * Internal speaker volume * Audio output jack volume * Internal microphone level * Audio input level * External audio input selection between line and microphone sensitivity These settings are sent to and from the monitor's microcontroller through ADB. Power Macintosh, Performa and Workgroup Server models 61xx, 71xx and 81xx all have the special HDI-45 port built-in. All other models require a special adapter to connect audio, video, and ADB separately to this monitor. The video input port pres ...

Computer Display
A computer monitor is an output device that displays information in pictorial or textual form. A discrete monitor comprises a visual display, support electronics, power supply, housing, electrical connectors, and external user controls. The display in modern monitors is typically an LCD with LED backlight, having by the 2010s replaced CCFL backlit LCDs. Before the mid- 2000s, most monitors used a CRT. Monitors are connected to the computer via DisplayPort, HDMI, USB-C, DVI, VGA, or other proprietary connectors and signals. Originally, computer monitors were used for data processing while television sets were used for video. From the 1980s onward, computers (and their monitors) have been used for both data processing and video, while televisions have implemented some computer functionality. In the 2000s, the typical display aspect ratio of both televisions and computer monitors has changed from 4:3 to 16:9. Modern computer monitors are mostly interchangeable with televisi ...

Aperture Grille
An aperture grille is one of two major technologies used to manufacture color cathode-ray tube (CRT) televisions and computer displays; the other is the shadow mask. Fine vertical wires behind the front glass of the display screen separate the different colors of phosphors into strips. These wires are positioned such that an electron beam from one of three guns at the rear of the tube is only able to strike phosphors of the appropriate color. That is, the blue electron gun will strike blue phosphors, but will find a wire blocks the path to red and green phosphors. The fine wires allow for a finer dot pitch as they can be spaced much closer together than the perforations of a shadow mask, and there need be no gap between adjacent horizontal pixels. During the display of bright images, a shadow mask warms, and expands outward in all directions (sometimes called blooming). Aperture grilles do not exhibit this behavior; when the wires heat up, they expand vertically. Because the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cathode Ray Tube
A cathode-ray tube (CRT) is a vacuum tube containing one or more electron guns, which emit electron beams that are manipulated to display images on a phosphorescent screen. The images may represent electrical waveforms ( oscilloscope), pictures (television set, computer monitor), radar targets, or other phenomena. A CRT on a television set is commonly called a picture tube. CRTs have also been used as memory devices, in which case the screen is not intended to be visible to an observer. The term ''cathode ray'' was used to describe electron beams when they were first discovered, before it was understood that what was emitted from the cathode was a beam of electrons. In CRT television sets and computer monitors, the entire front area of the tube is scanned repeatedly and systematically in a fixed pattern called a raster. In color devices, an image is produced by controlling the intensity of each of three electron beams, one for each additive primary color (red, green, and bl ...

Apple Inc
Apple Inc. is an American multinational technology company headquartered in Cupertino, California, United States. Apple is the largest technology company by revenue (totaling in 2021) and, as of June 2022, is the world's biggest company by market capitalization, the fourth-largest personal computer vendor by unit sales and second-largest mobile phone manufacturer. It is one of the Big Five American information technology companies, alongside Alphabet, Amazon, Meta, and Microsoft. Apple was founded as Apple Computer Company on April 1, 1976, by Steve Wozniak, Steve Jobs and Ronald Wayne to develop and sell Wozniak's Apple I personal computer. It was incorporated by Jobs and Wozniak as Apple Computer, Inc. in 1977 and the company's next computer, the Apple II, became a best seller and one of the first mass-produced microcomputers. Apple went public in 1980 to instant financial success. The company developed computers featuring innovative graphical user inter ...

Trinitron
Trinitron was Sony's brand name for its line of aperture-grille-based CRTs used in television sets and computer monitors. One of the first truly innovative television systems to enter the market since the 1950s, the Trinitron was announced in 1968 to wide acclaim for its bright images, about 25% brighter than common shadow mask televisions of the same era. Constant improvement in the basic technology and attention to overall quality allowed Sony to charge a premium for Trinitron devices into the 1990s. Patent protection on the basic Trinitron design ran out in 1996, and it quickly faced a number of competitors at much lower prices. Sony responded by introducing their flat-screen FD Trinitron designs (WEGA), which maintained their premier position in the market into the early 2000s. However, these designs were surpassed relatively quickly by plasma and LCD designs. Sony removed the last Trinitron televisions from their product catalogs in 2006, and ceased production in early 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HDI-45 Connector
The HDI-45 was one of Apple Computer's proprietary cable-to-onboard video connectors. A 45-pin connector, the HDI stands for High-Density Interconnect. Use These connectors were used only in the first generation Power Macintosh computers (the Power Macintosh 6100, 7100 and 8100), specifically connecting these computers to the Apple AudioVision 14 Display, the only display to use this connector. Other Apple displays and third-party displays could be used with a special adapter for the receptacle on the computer ("Canneloni", Apple part M2681LL/A or 590-0796-A) or a breakout cable ("Calamari", Apple M1243LL/A or 590-0793-A) for the permanently attached cable to the monitor that converts this unusual port to a standard DA-15 connector. Technical In addition to carrying analog RGB video, the connector supports analog stereo audio signals (input and output), Apple Desktop Bus (ADB), and S-video input. Because the AudioVision 14 Display has front-mounted connectors for ADB and audi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
S-Video
S-Video (also known as separate video, Y/C, and erroneously Super-Video ) is an analog video signal format that carries standard-definition video, typically at 525 lines or 625 lines. It encodes video luma and chrominance on two separate channels, achieving higher image quality than composite video which encodes all video information on one channel. It also eliminates several types of visual defects such as dot crawl which commonly occur with composite video. Although it improved over composite video, S-Video has lower color resolution than component video, which is encoded over three channels. The Atari 800 was the first to introduce separate Chroma/Luma output in late 1979. However, S-Video did not get widely adopted until JVC's introduction of the S-VHS (Super-VHS) format in 1987, which is why it is sometimes incorrectly referred to as "Super-Video." Before the shift towards digital video the S-video format was widely used by consumers, but it was rarely used in professiona ...

Apple Desktop Bus
Apple Desktop Bus (ADB) is a proprietary bit-serial peripheral bus connecting low-speed devices to computers. It was introduced on the Apple IIGS in 1986 as a way to support low-cost devices like keyboards and mice, allowing them to be connected together in a daisy chain without the need for hubs or other devices. Apple Device Bus was quickly introduced on later Macintosh models, on later models of NeXT computers, and saw some other third-party use as well. Like the similar PS/2 connector used in many PC-compatibles at the time, Apple Desktop Bus was rapidly replaced by USB as that system became popular in the late 1990s; the last external Apple Desktop Bus port on an Apple product was in 1999, though it remained as an internal-only bus on some Mac models into the 2000s. History AppleBus Early during the creation of the Macintosh computer, the engineering team had selected the fairly sophisticated Zilog 8530 to supply serial communications. This was initially done to allow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Microcontroller
A microcontroller (MCU for ''microcontroller unit'', often also MC, UC, or μC) is a small computer on a single VLSI integrated circuit (IC) chip. A microcontroller contains one or more CPUs (processor cores) along with memory and programmable input/output peripherals. Program memory in the form of ferroelectric RAM, NOR flash or OTP ROM is also often included on chip, as well as a small amount of RAM. Microcontrollers are designed for embedded applications, in contrast to the microprocessors used in personal computers or other general purpose applications consisting of various discrete chips. In modern terminology, a microcontroller is similar to, but less sophisticated than, a system on a chip (SoC). An SoC may connect the external microcontroller chips as the motherboard components, but an SoC usually integrates the advanced peripherals like graphics processing unit (GPU) and Wi-Fi interface controller as its internal microcontroller unit circuits. Microcontrollers are use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AudioVision Video Input
Audiovision was a Swedish metal band that produced two albums, the second in 2010. History Christian Liljegren, known for his work on Narnia and Divinefire, started up Audiovision during 2003 as a solo project. The first album ''The Calling'' was released in late 2004 in Europe and Japan, produced by Lars Chriss (Lion's Share, Road to Ruin). The guest list on ''The Calling'' featured Bruce Kulick (KISS, Grand Funk Railroad), Jeff Scott Soto (W.E.T., Talisman, Yngwie Malmsteen, Journey), Mic Michaeli (Europe), Tony Franklin (Blur Murder, Whitesnake), Mats Levén (Treat, At Vance, Krux, Yngwie Malmsteen) and Sampo Axelsson (Crawley, Glenn Hughes, Lion's Share, Road to Ruin) In 2009, Christian formed a touring and recording band and ended Audiovision as a studio project. During 2009, the first shows were played in Sweden, Norway and Germany, and, in the summer, Audiovision started to record their second album ''Focus'' with producer Erik Mårtensson (W.E.T., Eclipse) overseeing ...
