HDMI stands for High Definition Multimedia Interface. It's a means of transferring video and audio signals from a source device while keeping it digital instead of converting it into analog just to have it go back to digital again, incorporating loss.
HDMI 1.3 adds these features to 1.2:
Increases single-link bandwidth to 340 MHz (10.2 Gbps)
Supports 30-bit, 36-bit, and 48-bit (RGB or YCbCr) color depths or over one billion colors, up from 24-bit in previous versions.
Supports xvYCC color standards.
Incorporates automatic audio syncing (lip sync) capability.
Supports output of Dolby TrueHD and DTS-HD Master Audio streams for external decoding by AV receivers.
TrueHD and DTS-HD are lossless audio codec formats used on HD DVDs and Blu-ray Discs. If the disc player can decode these streams into uncompressed audio, then HDMI 1.3 is not necessary, as all versions of HDMI can transport uncompressed audio.
Availability of a new mini connector for devices such as camcorders.

HDMI, short for high definition multimedia interface, is quickly becoming the standard for digital audio and video connection, as it is the first type of cable that can carry all digital audio and video signals uncompressed over the same interconnect. Used as the official connector for high definition television sets, HDMI Cable eliminates the need for multiple cables behind your home theater system because it carries both audio and video signals. Its counterpart, DVI cabling, only supports digital video, meaning a separate audio cable is also necessary. Therefore, if you’re looking to increase quality and decrease clutter, HDMI cables are the way to go.

HDMI cable: The Catalyst for the DTV Revolution
Backed by some of the industry's biggest names, High-Definition Multimedia Interface (HDMI) cables will enable true high definition audio/video content for consumers. Content providers, system operators and consumer electronics manufacturers are rallying behind a standard that will finally deliver on DTV's long-awaited promises.
What are HDMI cables?
HDMI cables are the first industry-supported, uncompressed, all-digital audio/video interface cable. HDMI stands for "High-Definition Multimedia Interface". By delivering crystal-clear, all-digital audio and video signals with a single cable, HDMI cables dramatically simplifies cabling and helps provide consumers with the highest-quality home theater experience. HDMI connection jacks are most often found on home theater devices that are capable of outputting some form of digital High Definition video signals such as digital HDTV televisions & projectors, up converting HD DVD players, HDTV cable & satellite boxes, home theater receivers and digital video recorders.
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 version 1.3 adds additional support for new lossless digital audio formats such as Dolby TrueHD and DTS-HD with bandwidth to spare to accommodate future enhancements and requirements. HDMI 1.3, released in June of 2006, is backwards compatible with all previous HDMI versions. More information and products please check our website www.wholesalehdmicable.com
