What really is HDMI?

HDMI stands for High Definition Multimedia Interface. It is a term used to describe an audio/video interface for transmitting uncompressed digital data. It is the first and only industry supported all digital interface on a single cable.  That is why it is so popular with all home theater applications. Instead of running separate cables for audio and video, consumers can just install one cable  making it easy yet providing amazing digital audio and video performance. HDMI can provide an interface between any  digital TV, DVD player , audio/video receiver and audio or video monitor over a single cable. HDMI has become the standard for high definition interface in both business and consumer electronic markets.

For consumers setting up home theater there is no difference between HDMI version 1.3 and 1.3a or 1.3b.

Not only is HDMI known for simple installations, but it is  intelligent. It  handles  two-way communication between a video source such as a DVD player and a digital television , allowing  automatic configurations and one-touch play. By using HDMI, devices automatically deliver the most effective format (e.g 480p vs 720p, 16:9 vs 4:3) for the display that it is connected to. This eliminates the need for the consumer to scroll through all the format options to guess what looks best. HDMI is totally compatible with DVI  devices. HDMI Digital televisions  will display video received from existing DVI-equipped products, and DVI-equipped TVs will display video from HDMI sources. However, be careful and check out  older PCs with DVI that maybe  designed only to support computer monitors and  not televisions. If you are considering the purchase of a  PC with DVI  you should  make sure that it specifically includes support for television formats and not just computer monitors.
