With the launch of version 1.3, HDMI continues to increase its overall capabilities to meet the needs of the High-Definition marketplace. HDMI 1.3 includes the following new features:
Higher Speed - 10.2 Gbps HDMI 1.3 increases its single-link bandwidth from 165 MHz (4.95 Gbps) to 340 MHz (10.2 Gbps) to support the demands of future high definition display devices:
Deep Color - increasing the color depth from millions to billions of colors
Higher resolutions - over 400% greater resolutions than 720p HDTV
High frame rates - higher refresh rates (up to 120 Hz) for smoother motion
New Lossless Audio Formats HDMI 1.3 adds additional support for new, loss less compressed digital audio formats Dolby® TrueHD and DTS-HD Master Audio™ for theater-like, professional sound quality.
Lip Sync HDMI 1.3 incorporates an automatic audio/video syncing capability that allows
devices to perform this synchronization automatically with accuracy.
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.
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.
