HDMI 1.3 is an improved specification for the HDMI standard, with upgrades to each of the HDMI components.
HDMI 1.3 offers a higher video throughput, at 340Mhz, to allow for higher resolution displays, Deep Color (up to 48-bit RGB or YCbCr color depths), and the new Dolby standards for lossless compressed high-definition audio.
HDMI 1.3 uses a smaller connector than the original HDMI connector. They are both similar in appearance, but the HDMI 1.3 plug measures about half the size.
HDMI 1.3 is expected to appear in commercial products by the end of the year, starting with the release of the Sony Playstation 3. Models of DVD players, high-definition displays, and AV receivers released in 2007 are also being designed with HDMI 1.3 connectors.

WHAT IS HDMI ?
HDMI stands for (H)igh (D)efinition (M)ultimedia (I)nterface.
In a constantly changing industry, HDMI is the current standard of an all-in-one, standardized, universal connector for audio/video applications. Featuring a modern design and backed by the biggest names in the electronic industry, HDMI is attempting to finally unify all digital media components with a single cable, remote, and interface.
HDMI is built with a 5 Gbps bandwidth limit, over twice that of HDTV (which runs at 2.2 Gbps), and is built forwards-compatible by offering unallocated pipeline for future technologies. The connectors are sliding contact (like FireWire and USB) instead of screw-on (like DVI), and are not nearly as bulky as most current video interfaces.
HDMI 1.3 further increases the bandwith limit to 10.2 Gbps, to allow for the video and audio improvements of the upgraded standard.

HDMI supports standard, enhanced, or high-definition video, plus multi-channel digital audio on a single cable. This video data is then encoded into TMDS for transmission digitally over HDMI. HDMI also includes support for 8-channel uncompressed digital audio. Beginning with version 1.2, HDMI now supports up to 8 channels of one-bit audio. One-bit audio is what is used on Super Audio CDs.
The standard Type A HDMI connector has 19 pins, and a higher resolution version called Type B, has been defined, although it is not yet in common use. Type B has 29 pins, allowing it to carry an expanded video channel for use with high-resolution displays. Type-B is designed to support resolutions higher than 1080p.
