HDMI is the first & only industry supported, uncompressed, all-digitalaudio/video interface.
HDMI provides an interface between any A/V source, such as a set-
top box, DVD player, or A/V receiver and an audio and/or video
monitor, such as a digital television (DTV), over a single cable.
HDMI supports standard, enhanced, or high-definition video, plus
multi-channel digital audio on a single cable.
Transmits all ATSC HDTV standards and supports 8-channel,
192kHz, uncompressed digital audio, all currently-available
compressed formats & lossless digital audio formats with bandwidthto spare to accommodate future enhancements and requirements
HDMI acts like Cat5, it passes a data signal not an RF signal like
CATV.

HDMI is DVI with the addition of:
- Audio (up to 8-channels uncompressed)
- Smaller Connector
- Support for YUV Color Space- CEC (Consumer Electronics Control)
- CEA-861B Info Frames
HDMI is fully backward compatible with DVI compliant
devices. HDMI DTVs will display video received fromexisting DVI-equipped products, and DVI-equipped
TVs & will display video from HDMI sources.Make sure
your DVI device supports HDCP.

Bandwidth more than doubled from 165 MHz(4.95 Gbps) to 340 MHz (10.2 Gbps) to supportHigher Resolution, Faster Refresh, and DeepColor.
HDMI is a conduit or pipe that moves data.
With more bandwidth we have more room for
more goodies today and in the future.
Backward compatible with legacy versions.

Manufacturing, non-approved HDMI cables can
produce poor results
Poor installation, long cable runs, improperactive devices, lack of knowledge
Conglomerations of circuit boards, twisted
cables, interconnects, connectors, andelectronic components can create a maze of
signal loss
