Component cable: A universal analog video standard
Component cable is just few years old and within this short span they have engulfed the entire market and claimed the accolades for delivering the functions with perfection. Component cable initially pose to be an un common feature which in an esoteric way hooked up video devices to become the near-universal analog video signal standard for home theater and the high-definition television. Only few years back S-video and composite were considered as the most common and widely acceptable video signal standards, but lately component cable has emerged as the leader because it is the only medium for transmitting common consumer analog signal type that supports progressive scan and high-definition resolutions, and this is also considered as the standard output format of DVD players.
Component cables now become an indispensable device in almost every home theater setup. To understand component cable properly and clearly, it is desirable to make some concepts clear. For example all conventional methods of sending an analog video signal from one device to another device involve a few basic types of information. These are the information about scan, the brightness information and the color information. Composite cable, s-video, component cable, and the various types of RGB cable follow their respective method for transition of these signals. In this respect component cable is akin to RGBHV, for example its color information is broken out into pieces to keep red, green and blue separate. However, instead of delivering red, green and blue as such, component cable is what is known as a “color-difference” signal.
