Higher speed: HDMI 1.3 increases its single-link bandwidth 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 Colour 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 colour: HDMI 1.3 supports 30-bit, 36-bit and 48-bit (RGB or YCbCr) colour depths, up the 24-bit depths in previous versions of the HDMI specification. Lets HDTVs and other displays go millions of colours to billions of colours Eliminates on-screen colour banding, for smooth tonal transitions and subtle gradations between colours 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 colour space: HDMI 1.3 removes virtually all limits on color ion. Next-generation colour space supports 1.8 times as many colours as existing HDTV signals Lets HDTVs display colours more accurately Enables displays with more natural and vivid colours 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 current ability to support high-bandwidth uncompressed digital audio and currently-available compressed formats (such as Dolby?Digital and DTS), HDMI 1.3 adds additional support for new, lossless compressed digital audio formats Dolby?TrueHD and DTS-HD Master Audio? -----------------------------
