New Audio And Video Cables For New Televisions

When new televisions are bought no one really considers the cables for audio and video. Often the new TV is brought home and then it's discovered they don't have the right cables to acheive the clarity in picture or sound. It's become even more complicated with the addition of HDTV, specialized video gaming setups and digital satellite.

HDMI cables make up the high-end of television cabling, and are the best choice for consumers that own HD televisions and video equipment. HDMI (which stands for High Definition Multimedia Interface) is a digital format using a 19-pin connector that provides essentially a plug-and-play solution for getting both high definition video and high resolution audio to a television from a satellite or cable box, BluRay player, or HD video game system, like the PS3 or XBOX360. While more expensive than other cable types, their ease of use and quality make the extra price worthwhile. HDMI is backwards compatible with the Digital Video Interface standard (DVI) which was originally developed for high-end computer monitors and graphic devices. While some DVI cables are seen in the consumer television industry, the fact that it is an older, video-only standard (no audio) means that it has been superseded by HDMI as a consumer cabling solution.

Component video cables are a video-only analog system that can actually deliver an HD signal to a television that supports that resolution. It is a standard that is falling out of favor due to both its analog signal and the fact that it doesn't support Digital Rights Management - read copy protection - like the DVI and HDMI standards. These cables feature three RCA connectors that are colored Red, Green and Blue corresponding to the color that cable transmits.

The two oldest standards are S-Video and Composite video cables. The S-Video was progressive in the 80's until Component Video was introduced. S-Video has a 4 pin connector and provided a good video signal at that time, it often came with the regular red and white RCA connectors for the audio portion. Composite video cables are the oldest, superseded by S-video, they had a yellow RCA connector and were often blended together with the red and white audio cables. Nowadays they should only be implemented for connecting an older VCR or DVD with the TV.

If a consumer is using DVI or Component video cabling in an HD system, some form of digital audio cable will be necessary to get the best sound quality as compared to the standard red and white RCA audio connectors. In most cases, this is accomplished using a digital fiber-optic cable, although some digital audio connections use a different type of RCA connector.
