What Is HDMI Cable ?

HDMI cable is the first and only industry-supported, uncompressed, all-digital audio/video interface. Over a single cable, HDMI provides an interface between modern audio/video devices (Blu-ray player, cable set-top box, DVD player, or  receiver) and digital displays.  HDMI supports standard, enhanced, or high-definition video, plus multi-channel digital audio on a single cable. It transmits all ATSC HDTV standards and supports 8-channel, 192kHz, uncompressed digital audio and all currently-available compressed formats (such as Dolby Digital and DTS), HDMI 1.3 added additional support for new lossless digital audio formats Dolby® TrueHD and DTS-HD Master Audio™ with bandwidth to spare to accommodate future enhancements and requirements.

The HDMI Founders include leading consumer electronics manufacturers Hitachi , Matsushita Electric Industrial (Panasonic), Philips, Sony, Thomson (RCA), Toshiba, and Silicon Image. Digital Content Protection, LLC (a subsidiary of Intel) is providing High-bandwidth Digital Content Protection (HDCP) for HDMI. In addition, HDMI has the support of major motion picture producers Fox, Universal, Warner Bros. and Disney, and system operators DirecTV, EchoStar (Dish Network) as well as CableLabs.

That is what HDMI cable means, hope this helps ^_^
