HDMI - What Is It?
HDMI (which stands for High-Definition Multimedia Interface) is the first industry-supported, uncompressed, all-digital audio/video interface.
To put it in jargon-free terms, its a high quality connection mechanism bewteen various digital home theater components.
HDMI is an interface standard that works between any audio/video source, such as a set-top box, DVD player, or an A/V receiver and an audio and/or video display or monitor, such as an LCD digital television (DTV), over a single cable.
HDMI supports standard, enhanced, or high-definition video, plus multi-channel digital audio on a single cable.
It transmits all ATSC HDTV standards and provides 100% complete and correct transmission of both the visual and audio digital signals.
The HDMI Founders are the leading consumer electronics manufacturers such as Hitachi , Panasonic, Philips, Sony, Thomson (RCA), Toshiba, and Silicon Image.
Another important aspect is Digital Content Protection. A subsidiary of Intel - Digital Content Protection, LLC - is providing High-bandwidth Digital Content Protection (HDCP) for HDMI.
Because it provides content security, HDMI has the support of major movie studios such as Fox, Universal, Warner Bros. and Disney.
