With the adoption of Deep Color and the xvYCC color space, HDMI 1.3 removes the previous interface-related restrictions on color selection. The interface will no longer be a constraining pipe that forces all content to fit within a limited set of colors, unlike all previous video interfaces.New HDMI 1.3 capabilities include: -- Higher speed: HDMI 1.3 increases its single-link bandwidth from 165MHz (4.95 gigabits per second) to 340 MHz (10.2 Gbps) to support the demands of future high definition display devices, such as higher resolutions, Deep Color and high frame rates. In addition, built into the HDMI 1.3 specification is the technical foundation that will let future versions of HDMI reach significantly higher speeds. -- Deep Color: HDMI 1.3 supports 30-bit, 36-bit and 48-bit (RGB or YCbCr) color depths, up from the 24-bit depths in previous versions of the HDMI specification. - Lets HDTVs and other displays go from millions of colors to billions of colors - Eliminates on-screen color banding, for smooth tonal transitions and subtle gradations between colors - Enables increased contrast ratio - Can represent many times more shades of gray between black and white. At 30-bit pixel depth, four times more shades of gray would be the minimum, and the typical improvement would be eight times or more -- Broader color space: HDMI 1.3 removes virtually all limits on color selection. - Next-generation "xvYCC" color space supports 1.8 times as many colors as existing HDTV signals - Lets HDTVs display colors more accurately - Enables displays with more natural and vivid colors -- New mini connector: With small portable devices such as HD camcorders and still cameras demanding seamless connectivity to HDTVs, HDMI 1.3 offers a new, smaller form factor connector option. -- Lip Sync: Because consumer electronics devices are using increasingly complex digital signal processing to enhance the clarity and detail of the content, synchronization of video and audio in user devices has become a greater challenge and could potentially require complex end-user adjustments. HDMI 1.3 incorporates an automatic audio/video synching capability that allows devices to perform this synchronization automatically with accuracy. -- New lossless audio formats: In addition to HDMI's current ability to support high-bandwidth uncompressed digital audio and currently-available compressed formats (such as Dolby(R) Digital and DTS), HDMI 1.3 adds additional support for new, lossless compressed digital audio formats Dolby(R) TrueHD and DTS-HD Master Audio(TM).
Products implementing the new HDMI specification will continue to bebackward compatible with earlier HDMI products.
"The dramatic increase in maximum speed achieved in HDMI 1.3 will enableHDMI to stay far ahead of the bandwidth demands of future high definition source and display devices," said Leslie Chard , president of HDMI Licensing,LLC. "As the de facto standard digital interface for the high definition and consumer electronics markets, HDMI is implementing the most innovative technologies today to fulfill the demands of tomorrow's consumers."

HDMI is the first and only consumer electronics industry-supported,uncompressed, all-digital audio/video interface. By delivering crystal-clear,all-digital audio and video via a single cable, HDMI dramatically simplifies cabling and helps provide consumers with the highest-quality home theaterexperience. HDMI provides an interface between any audio/video source, such asa 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.
