Cables and cords are essential to operating your favorite device. Component video separates the video signal into individual streams and these video streams are carried via three cables, colored red, and green and blue that normally comes bundled with RCA type jack connectors. Component video signals will provide better color resolution, purity and fidelity than S-Video and composite video signals.

For electronics like televisions, digital cameras and camcorders there are DVI cables, HDMI cables and S-video cables. Also, HDMI cables are used for content management. For example, a manufacturer would use it to enable service providers to control access to specific content.

DVI stands for Digital Video Interface, while HDMI stands for High-Definition Multimedia Interface. The biggest difference between DVI and HDMI is that DVI is used solely for video and HDMI cables carry both the video and audio signals through one signal. There are RCA cables, which are also known as composite cables, which include one connection for video which is usually yellow and it includes parts for left and right audio channels, which are usually white and red respectively.

Audio video Cables are higher quality analog video cables which are generally used in hooking up your television, VCR, DVD player, or similar to another video source, such as a computer. There are also component cables which are essentially providers of higher quality and better signal throughput.

The principle idea behind HDMI is the use of a single interconnects instead of several cables when connecting an audio video source, such as a set top box or DVD player and an audio and or video monitor, such as a plasma TV, over a single HDMI cable.

The use of a single HDMI cable that replaces the maze of cabling behind home entertainment centers is the primary advantage brought about by this new standard. This is not the case with DVI supports digital video only hence, a separate audio cable is needed to transport digital audio when a DVI cable is used.

Audio Video cables are used to hook up receivers, tuners, radios, stereos, micro shelf systems and speakers. Other cables that are also used in audio video equipment are optical cables which are used to transmit light as the signal and coaxial cables. For cords, some of most popular are actually wire harnesses which are used in cars to power a car stereo. For more details http://www.av-setup.com
