Dual-link DVI
Digital Visual Interface (DVI) is a video display interface developed by the Digital Display Working Group (DDWG). The digital interface is used to connect a video source, such as a video display controller, to a display device, such as a computer monitor. It was developed with the intention of creating an industry standard for the transfer of uncompressed digital video content. DVI devices manufactured as DVI-I have support for analog connections, and are compatible with the analog VGA interface by including VGA pins, while DVI-D devices are digital-only. This compatibility, along with other advantages, led to its widespread acceptance over competing digital display standards Plug and Display (P&D) and Digital Flat Panel (DFP). Although DVI is predominantly associated with computers, it is sometimes used in other consumer electronics such as television sets and DVD players. History An earlier attempt to promulgate an updated standard to the analog VGA connector was made by t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gender Of Connectors And Fasteners
In electrical and machine, mechanical trades and manufacturing, each half of a pair of mating Electrical connector, connectors or fasteners is conventionally designated as male or female, a distinction referred to as its gender. The female connector is generally a receptacle that receives and holds the male connector. Gender of connectors and fasteners#Abbreviations and alternate terminology, Alternative terms such as ''plug'' and ''socket'' or ''jack'' are sometimes used, particularly for Electrical connector#Jacks and plugs, electrical connectors. The assignment is a direct analogy with male and female Sex organ, genitalia. The part bearing one or more protrusions, or which fits inside the other, is designated ''male'', while the one with the corresponding indentations, or fitting outside the other, is designated ''female''. Extension of the analogy results in the verb ''to mating, mate'' being used to describe the process of connecting two corresponding parts together. In som ...

Data Compression
In information theory, data compression, source coding, or bit-rate reduction is the process of encoding information using fewer bits than the original representation. Any particular compression is either lossy or lossless. Lossless compression reduces bits by identifying and eliminating statistical redundancy. No information is lost in lossless compression. Lossy compression reduces bits by removing unnecessary or less important information. Typically, a device that performs data compression is referred to as an encoder, and one that performs the reversal of the process (decompression) as a decoder. The process of reducing the size of a data file is often referred to as data compression. In the context of data transmission, it is called source coding: encoding is done at the source of the data before it is stored or transmitted. Source coding should not be confused with channel coding, for error detection and correction or line coding, the means for mapping data onto a sig ...

Micro Ribbon Connector
The micro ribbon or miniature ribbon connector is a common type of electrical connector for a variety of applications, such as in computer and telecommunications equipment having many contacts. The connector contains two parallel rows of lead (electronics), contacts within a electromagnetic shielding, shielded case having a characteristic D-shape similar to that used in D-subminiature connectors. The contacts are not pins, but small flat bands of metal, called ribbon contacts. The connectors are manufactured in many capacities, including 14-, 24-, 36-, 50-, 64-, and 100-pin varieties. They may be mounted on printed circuit board, boards, panels, or may terminate Telco cable, cables. Wires are attached by means of solder, crimp (joining), crimping or insulation-displacement connector, insulation displacement. Female connectors have bail handle, bail locks for a sturdy connection to the gender of connectors and fasteners, male connector. Screws may also be employed to secure ...

Transition-minimized Differential Signaling
Transition-minimized differential signaling (TMDS) is a technology for transmitting high-speed serial data used by the DVI and HDMI video interfaces, as well as by other digital communication interfaces. The transmitter incorporates a coding algorithm which reduces electromagnetic interference over copper cables and enables robust clock recovery at the receiver to achieve high skew tolerance for driving longer cables as well as shorter low-cost cables. Description TMDS was developed by Silicon Image Inc. as a member of the Digital Display Working Group. TMDS is similar to low-voltage differential signaling (LVDS) in that it uses differential signaling to reduce electromagnetic interference (EMI) which allows faster signal transfers with increased accuracy. TMDS also uses a twisted pair for noise reduction, rather than coaxial cables which are conventional for carrying video signals. Like LVDS, the data is transmitted serially over the data link. When transmitting vi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
VESA Plug And Display
VESA Plug and Display (abbreviated as P&D) is a video connector that carries digital signals for monitors, such as flat panel displays and video projectors, ratified by Video Electronics Standards Association (VESA) in 1997. Introduced around the same time as the competing connectors for the Digital Visual Interface (DVI, 1999) and VESA's own Digital Flat Panel (DFP, 1999), it was marketed as a replacement for the VESA Enhanced Video Connector (EVC, 1994). Unlike DVI, it never achieved widespread implementation. The P&D connector shares the 30-pin plus quad- coax layout of EVC, which carries digital video, analog video, and data over Universal Serial Bus (USB) and IEEE 1394 (FireWire). At a minimum, the P&D connector is required to carry digital video, in which case the connector is designated P&D-D; when both digital and analog video are included, the connector is designated P&D-A/D. Design The P&D receptacle and plug are required to bear a standardized symbol to designate th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FireWire
IEEE 1394 is an interface standard for a serial bus for high-speed communications and isochronous real-time data transfer. It was developed in the late 1980s and early 1990s by Apple in cooperation with a number of companies, primarily Sony and Panasonic. It is most commonly known by the name FireWire (Apple), though other brand names exist such as i.LINK (Sony), and Lynx ( Texas Instruments). The copper cable used in its most common implementation can be up to long. Power and data is carried over this cable, allowing devices with moderate power requirements to operate without a separate power supply. FireWire is also available in Cat 5 and optical fiber versions. The 1394 interface is comparable to USB. USB was developed subsequently and gained much greater market share. USB requires a host controller whereas IEEE 1394 is cooperatively managed by the connected devices. History and development FireWire is Apple's name for the IEEE 1394 High Speed Serial Bus. Its d ...

VESA Enhanced Video Connector
The VESA Enhanced Video Connector (EVC) is a VESA standard that was intended to reduce the number of cables around a computer by incorporating video, audio, FireWire and USB into a single cable system, terminating in a 35-pin Molex MicroCross connector. The intent was to make the monitor the central point of connection. The EVC physical standard was ratified in November 1994, and the pinout and signaling standard followed one year later. History The Video Electronic Standards Association (VESA) began working on a successor to the VGA connector for analog video and released the EVC physical standard in November 1994, followed by a pinout and signal standard in November 1995. After the P&D standard was released in June 1997, revisions to the EVC standards were issued in November 1997. EVC was used for few products, perhaps most commonly found on the HP9000 B/C/J-class workstations introduced in 1997. Although EVC did not find favour with computer manufacturers, it evolved into ...

Video Electronics Standards Association
VESA (), formally known as Video Electronics Standards Association, is an American technical standards organization for computer display standards. The organization was incorporated in California in July 1989To retrieve the information, search for Entity Number C1645094. and has its office in San Jose. It claims a membership of over 300 companies. In November 1988, NEC Home Electronics announced its creation of the association to develop and promote a Super VGA computer display standard as a successor to IBM's proprietary Video Graphics Array (VGA) display standard. Super VGA enabled graphics display resolutions up to 800×600 pixels, compared to VGA's maximum resolution of 640×480 pixels—a 56% increase. The organization has since issued several additional standards related to computer video displays. Widely used VESA standards include DisplayHDR, DisplayPort, and Flat Display Mounting Interface.

DVD Player
A DVD player is a machine that plays DVDs produced under both the DVD-Video and DVD-Audio technical standards, two different and incompatible standards. Some DVD players will also play audio CDs. DVD players are connected to a television to watch the DVD content, which could be a movie, a recorded TV show, or other content. History The first DVD player is claimed to have been created by the Japanese electronics vendor Toshiba in November 1996, and the first to be released to US customers is claimed to have been by Sony in April 1997. Some manufacturers originally announced that DVD players would be available as early as the middle of 1996. These predictions were too optimistic. Delivery was initially held up for "political" reasons of copy protection demanded by movie studios, but was later delayed by lack of movie titles. The first players appeared in Japan on November 1, 1996, followed by the United States on March 31, 1997, with distribution limited to only seven major ...

Television Set
A television set or television receiver (more commonly called TV, TV set, television, telly, or tele) is an electronic device for viewing and hearing television broadcasts, or as a computer monitor. It combines a tuner, display, and loudspeakers. Introduced in the late 1920s in mechanical form, television sets became a popular consumer product after World War II in electronic form, using cathode-ray tube (CRT) technology. The addition of color to broadcast television after 1953 further increased the popularity of television sets in the 1960s, and an outdoor antenna became a common feature of suburban homes. The ubiquitous television set became the display device for the first recorded media for consumer use in the 1970s, such as Betamax, VHS; these were later succeeded by DVD. It has been used as a display device since the first generation of home computers (e.g. Timex Sinclair 1000) and dedicated video game consoles (e.g., Atari) in the 1980s.
