Though mostly superseded in the past decadeby digital video connectors that can handle more data and provide aclearer picture, analog video connectors are still employed on numerouslegacy devices and still form an integral portion of many video displayrelays. Whether you need to hook your DVD player up to an analogprojector, or pass data between your computer and an analog monitor,knowing the different types of analog video connectors available on theconsumer market can prove essential to making the most of yourAudio/Visual setup. VGA VGAis the most commonly used form of analog video connector fortransferring data between PCs and display monitors. You’ll find VGAconnectors on most PCs, laptops, and monitors built between 1987 andthe early 2000s. Because of how easy they are to use, VGA connectorshave been employed on numerous computer monitors and projectorsintended for use in the consumer market. The initialsVGA stand for Video Graphics Array. You’ll be able to easily identify aVGA connector by its shape. VGA connectors employ a D-shaped,subminiature-type connector with 15 pins. This connector is oftenidentifiable by its metallic sheathing and blue-colored, molded grip. VGAhas come to be known as the lowest common denominator for computergraphics hardware. You won’t get particularly amazing resolutions froma VGA connector, but its widespread compatibility means that almost allanalog monitors, projectors, and PCs will feature some sort of VGAinput. If you need to connect your computer with a variety of differentanalog displays, a VGA cable might be a good fit for that job. S-Video WhereasVGA connectors found their primary use in connecting PCs to externaldisplays, S-video connectors were more commonly used in the consumervideo market, showing up frequently on VHS players, TVs, and inEuropean Audio/Visual setups. The term S-Video is aportmanteau of the words Super Video. S-Video connectors carry standarddefinition (480i or 576i resolution) video signals via a four-pin,mini-DIN connector. As opposed to composite video connectors, whichcarry video data via a single channel, S-Video connectors transfervideo data in two, synchronized channels. The upshot of this technicalinnovation is that S-Video connectors provide slightly better videoquality than composite video connectors, though S-Video signals requiremore processing power in order to display properly. Conversely, S-Videoconnectors provide a slightly lower quality of video than three-plug,component video connectors. S-Video is less common onPCs than it is on VCRs and TVs, though some legacy PC and Macintoshmodels do feature S-Video connectors. Composite Video CompositeVideo can be a little confusing, as its connector isn’t as readilyidentifiable as the VGA or S-Video connectors. As opposed to the VGAconnector, which employs 15 pins, and the S-Video connector, whichemploys two channels and four pins, composite video connectors use onlya single plug and transmit video via a single channel. Though thismeans that composite video connectors can’t provide the same picturequality as the two connectors we just discussed, it also means thatcomposite video schemes have been able to find wide employment onconsumer video devices, owing to their simple interface and diminutivesize. You’ll typically run into composite videoconnectors as part of a three-pronged, RCA connector cable. RCAconnectors are the circular, red, white, and yellow connectors you seeon the backs of almost all VCRs, DVD players, and TVs. While the redand white ports allow you to transfer stereo audio signals to and fromthese entertainment devices, the yellow port is intended fortransmitting composite video. You can also get composite video cableswith only a single, yellow connector, but these are rarer, as theyallow for video data transfer, but not audio. If you’re looking totransfer analog video data in your home entertainment system, you couldscarcely find a safer bet than a composite video cable.
