HDMI Cable and Connectors Guidelines

HDMI Cable and Connectors, HDMI (High Definition Multimedia Interface) is way to deliver uncompressed signals straight from any HDMI capable device (DVD player, cable box, video game system etc) to your similarly equipped television or computer monitor. The benefits of audio and video traveling in the same cable are enhanced picture and sound quality. Since its digital there is no signal loss as there is with other connectors such as s-video and component.

HDMI is an ever evolving technology with several versions. Version 1.1 was support for DVD audio. Version 1.2 added support for Super Audio CD's and was changed to better support new advances in PC video formats. Version 1.2a added several verification tests for technical consistency. All of the HDMI versions are backward compatible. There is no need to buy new cables when a new version is released.

HDMI cables can be custom made. Websites online sell lengths from a few feet to a few hundred feet. This can be used to wire a house for home theater without the mess of wires that can accumulate. One HDMI connector can replace up to eleven analog cables. Generic cables can be significantly less expensive than those sold in retail stores. Studies have shown that brand new "designer" cables show no difference in audio or video quality over inexpensive, generic cables. Many of the stores that sell these higher priced cables receive a cut of the profits therefore encouraging the upsell. This happens most at the time a TV is sold. 

HDMI is like DVI but with a few differences. HDMI adds up to eight uncompressed audio channels, is a smaller connector, includes support for YUV Color Space, is CEC (Consumer Electronics Control)certified and has CEA-861B InfoFrames. HDMI is fully compatible withDVI enabled devices. For a HDMI-DVI connection, an extra audio cable is needed. The simple convergence between the two allows PC's to enjoy media content such as high definition movies and multi-channel audio formats. In turn, this broadens the market by hundreds of millions of devices.

HDMI was developed as a universal cable to deal with the ever expanding industry of high definition media and a way to not confuse the consumer with a myriad of different options to experience this content. Users can be assured that they are getting the best possible picture available when they are using an HDMI cable when viewing HD media.
